Range values to be calculated in PHP Loop

This question was asked by a Abdullah on stackoverflow. So i thought of giving him a better solution.

513b78e69337473f9f7b16e586f7dc9d

As you can see from the above image. For a range of number, each number must be added and divided by the length to get the average and then check if the average is greater than or equal to 7.5, he need to set the is heavy value to yes if not No.

Here is the solution i gave him.

<?php

$results = heavyDecC(2685, 5875);

// Display results like this
foreach ($results as $id){
        echo "--------------------------<br/>";
        foreach($id as $key => $val){
            echo $key . " - " . $val . "<br />";
        }
    }

function heavyDecC ($x,$y) {

	for($i=$x; $i<=$y; $i++){
		$num = $x;
		$isHeavy = "No";
		$num_length = strlen((string)$num);
		$array  = array_map('intval', str_split($num));
		$sum = array_sum($array);
		$average = ($sum / $num_length);

			if($average > 7){
				$isHeavy = "Yes";
			}else {
				$isHeavy = "No";
			}

		$newdata =  array (
		      'Number' => $num,
		      'average' => $average,
		      'is_heavy' => $isHeavy
		    );

		$md_array[$i]= $newdata;
		$x++;
	}

return $md_array;
}

?>

<?php

$results = heavyDecC(2685, 5875);

// Display results like this

foreach ($results as $id){

echo "--------------------------<br/>";

foreach($id as $key => $val){

echo $key . " - " . $val . "<br />";

}

function heavyDecC ($x,$y) {

for($i=$x; $i<=$y; $i++){

$num = $x;

$isHeavy = "No";

$num_length = strlen((string)$num);

$array = array_map('intval', str_split($num));

$sum = array_sum($array);

$average = ($sum / $num_length);

if($average > 7){

$isHeavy = "Yes";

}else {

$isHeavy = "No";

}

$newdata = array (

'Number' => $num,

'average' => $average,

'is_heavy' => $isHeavy

);

$md_array[$i]= $newdata;

$x++;

}

return $md_array;

}

Results looks like this.

Number - 2996
average - 6.5
is_heavy - No
--------------------------
Number - 2997
average - 6.75
is_heavy - No
--------------------------
Number - 2998
average - 7
is_heavy - No
--------------------------
Number - 2999
average - 7.25
is_heavy - Yes
--------------------------
Number - 3000
average - 0.75
is_heavy - No
--------------------------
Number - 3001
average - 1
is_heavy - No
--------------------------
Number - 3002
average - 1.25
is_heavy - No

Number - 2996

average - 6.5

is_heavy - No

--------------------------

Number - 2997

average - 6.75

is_heavy - No

--------------------------

Number - 2998

--------------------------

Number - 2999

average - 7.25

--------------------------

Number - 3001

average - 1

is_heavy - No

--------------------------

Number - 3002

average - 1.25

is_heavy - No

Hope this will be helpfull. Tnx. 🙂

Permissions in Android 6.0 API Level 23

One of the important change that was introduced in Android 6.0 (API level 23) is the users grant permissions to apps. With this change all the device that is running Android 6.0 and above will have to request the permissions while the app is running, not when they install the app.

This approach will help the users to decide which permissions are necessary for an app and to decide weather to give that permission or not. Now its all depends on the users hand. It also gives the user more control over the app’s functionality.

for example, a user could choose to give a camera app access to the camera but not to the device location. The user can revoke the permissions at any time, by going to the app’s Settings screen.

System permissions are divided into two sections, normal and dangerous:

Normal permissions do not directly risk the user’s privacy. If your app lists a normal permission in its manifest, the system grants the permission automatically.
Dangerous permissions can give the app access to the user’s confidential data. If your app lists a normal permission in its manifest, the system grants the permission automatically. If you list a dangerous permission, the user has to explicitly give approval to your app.

Below you can find the list of Normal and Dangerous permissions list.

Normal permissions

Dangerous permissions

In this tutorial i will give you instructions of loading images in a recycler view using Picasso library. One you complete this tutorial your application will look like this.

This application will list image of the android versions and its version names. OK. lets get started.

1. Create a new project.

Open up your android studio and create a new project with the name Recyclerimage. Note you can give any name you like, but for this tutorial i suggest using the same name.

2. Create a layout for the recycler view.

Inside your res/layout/ folder create a new file called row_layout.xml . This file will have a simple image view and a text view and copy and paste the below code.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    card_view:cardCornerRadius="5dp">

    <RelativeLayout
        android:layout_marginLeft="20dp"
        android:layout_marginTop="20dp"
        android:layout_marginBottom="20dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ImageView
            android:layout_width="60dp"
            android:layout_height="60dp"
            android:id="@+id/img_android"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:layout_marginRight="20dp"/>

        <TextView
            android:layout_marginTop="10dp"
            android:textSize="18sp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/tv_android"
            android:textStyle="bold"
            android:layout_centerVertical="true"
            android:layout_toRightOf="@+id/img_android" />
    </RelativeLayout>

</android.support.v7.widget.CardView>

<?xml version="1.0" encoding="utf-8"?>

<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"

xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginTop="5dp"

android:layout_marginLeft="5dp"

android:layout_marginRight="5dp"

card_view:cardCornerRadius="5dp">

<RelativeLayout

android:layout_marginLeft="20dp"

android:layout_marginTop="20dp"

android:layout_marginBottom="20dp"

android:layout_width="match_parent"

android:layout_height="wrap_content">

<ImageView

android:layout_width="60dp"

android:layout_height="60dp"

android:id="@+id/img_android"

android:layout_alignParentLeft="true"

android:layout_alignParentTop="true"

android:layout_marginRight="20dp"/>

<TextView

android:layout_marginTop="10dp"

android:textSize="18sp"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/tv_android"

android:textStyle="bold"

android:layout_centerVertical="true"

android:layout_toRightOf="@+id/img_android" />

</RelativeLayout>

</android.support.v7.widget.CardView>

Then add a recycler view to your activity_main.xml as shown in below code. Make sure to change your tools:contex property according to your project package name.

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="baman.lankahomes.lk.recyclerimage.MainActivity">

<android.support.v7.widget.RecyclerView
    android:id="@+id/card_recycler_view"
    android:scrollbars="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</android.support.design.widget.CoordinatorLayout>

<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:fitsSystemWindows="true"

tools:context="baman.lankahomes.lk.recyclerimage.MainActivity">

<android.support.v7.widget.RecyclerView

android:id="@+id/card_recycler_view"

android:scrollbars="vertical"

android:layout_width="match_parent"

android:layout_height="match_parent"/>

</android.support.design.widget.CoordinatorLayout>

3. Add permissions to Android manifest.

This application need internet connection to download images from URL, therefore it is necessary to add request the internet permission through your AndroidManifest.xml file as shown in the below code.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="baman.lankahomes.lk.recyclerimage">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="baman.lankahomes.lk.recyclerimage">

<uses-permission android:name="android.permission.INTERNET" />

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:supportsRtl="true"

android:theme="@style/AppTheme">

<intent-filter>

</intent-filter>

</activity>

</application>

</manifest>

4. Creating data adapter.

Now create a new java class called DataAdapter.java inside your package and then copy and paste the below code.

package baman.lankahomes.lk.recyclerimage;

/**
 * Created by baman on 6/17/16.
 */

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import com.squareup.picasso.Picasso;

import java.util.ArrayList;

public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> {
    private ArrayList<AndroidVersion> android_versions;
    private Context context;

    public DataAdapter(Context context,ArrayList<AndroidVersion> android_versions) {
        this.context = context;
        this.android_versions = android_versions;

    }

    @Override
    public DataAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.row_layout, viewGroup, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int i) {

        viewHolder.tv_android.setText(android_versions.get(i).getAndroid_version_name());
        Picasso.with(context).load(android_versions.get(i).getAndroid_image_url()).resize(60, 60).into(viewHolder.img_android);
    }

    @Override
    public int getItemCount() {
        return android_versions.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder{
        TextView tv_android;
        ImageView img_android;
        public ViewHolder(View view) {
            super(view);

            tv_android = (TextView)view.findViewById(R.id.tv_android);
            img_android = (ImageView)view.findViewById(R.id.img_android);
        }
    }
}

package baman.lankahomes.lk.recyclerimage;

/**

* Created by baman on 6/17/16.

import android.content.Context;

import android.support.v7.widget.RecyclerView;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

import android.widget.TextView;

import com.squareup.picasso.Picasso;

import java.util.ArrayList;

public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> {

private ArrayList<AndroidVersion> android_versions;

private Context context;

public DataAdapter(Context context,ArrayList<AndroidVersion> android_versions) {

this.context = context;

this.android_versions = android_versions;

}

@Override

public DataAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {

View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.row_layout, viewGroup, false);

return new ViewHolder(view);

}

@Override

public void onBindViewHolder(ViewHolder viewHolder, int i) {

viewHolder.tv_android.setText(android_versions.get(i).getAndroid_version_name());

Picasso.with(context).load(android_versions.get(i).getAndroid_image_url()).resize(60, 60).into(viewHolder.img_android);

}

@Override

public int getItemCount() {

return android_versions.size();

}

public class ViewHolder extends RecyclerView.ViewHolder{

TextView tv_android;

ImageView img_android;

public ViewHolder(View view) {

super(view);

tv_android = (TextView)view.findViewById(R.id.tv_android);

img_android = (ImageView)view.findViewById(R.id.img_android);

}

Make sure to change the package name according to your project.

Now create another class inside your package and name it as AndroidVersion.java and then copy and paste the blow code.

package baman.lankahomes.lk.recyclerimage;

/**
 * Created by baman on 6/17/16.
 */

public class AndroidVersion {

    private String android_version_name;
    private String android_image_url;

    public String getAndroid_version_name() {
        return android_version_name;
    }

    public void setAndroid_version_name(String android_version_name) {
        this.android_version_name = android_version_name;
    }

    public String getAndroid_image_url() {
        return android_image_url;
    }

    public void setAndroid_image_url(String android_image_url) {
        this.android_image_url = android_image_url;
    }
}

package baman.lankahomes.lk.recyclerimage;

/**

* Created by baman on 6/17/16.

public class AndroidVersion {

private String android_version_name;

private String android_image_url;

public String getAndroid_version_name() {

return android_version_name;

}

public void setAndroid_version_name(String android_version_name) {

this.android_version_name = android_version_name;

}

public String getAndroid_image_url() {

return android_image_url;

}

public void setAndroid_image_url(String android_image_url) {

this.android_image_url = android_image_url;

}

Make sure to change the package name.

Now lets modify the MainActivity.java class to get the list of images and strings to add it in to the recycler view.

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;


import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    private final String android_version_names[] = {

        recyclerView.setHasFixedSize(true);
        RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
        recyclerView.setLayoutManager(layoutManager);

        ArrayList androidVersions = prepareData();
        DataAdapter adapter = new DataAdapter(getApplicationContext(),androidVersions);
        recyclerView.setAdapter(adapter);

    }
    private ArrayList prepareData(){

        ArrayList android_version = new ArrayList<>();
        for(int i=0;i<android_version_names.length;i++){
            AndroidVersion androidVersion = new AndroidVersion();
            androidVersion.setAndroid_version_name(android_version_names[i]);

5. Modify compile dependencies in your Build.gradle file.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "baman.lankahomes.lk.recyclerimage"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
}

apply plugin: 'com.android.application'

android {

compileSdkVersion 23

buildToolsVersion "23.0.2"

defaultConfig {

applicationId "baman.lankahomes.lk.recyclerimage"

minSdkVersion 17

targetSdkVersion 23

versionCode 1

versionName "1.0"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

testCompile 'junit:junit:4.12'

compile 'com.squareup.picasso:picasso:2.5.2'

compile 'com.android.support:recyclerview-v7:23.1.1'

compile 'com.android.support:cardview-v7:23.1.1'

compile 'com.android.support:appcompat-v7:23.1.1'

compile 'com.android.support:design:23.1.1'

}

That’s it. Save the project and run it on your device or emulator. It should work fine. If you have any comments or queries leave it in the comments section below. Thank you. Happy coding 🙂

Yesterday, i have done an piratical test for an interview. The task provided is to post a username and password to an https url and also to get the response results using an https connection in another url. I have successfully completed the task, but it took me around five hours. I wasted lot of time in researching on how to do an https post. Therefore i thought i could share some of the important information, so that it will we helpful for some one. please not i am not going to share the entire solution.

First create an custom socket factory inside your package. Use the below code.

package baman.lankahomes.lk.zupportdesk;

/**
 * Created by baman on 6/13/16.
 */
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.conn.ssl.SSLSocketFactory;

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class MySSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
}

package baman.lankahomes.lk.zupportdesk;

/**

import javax.net.ssl.SSLContext;

public class MySSLSocketFactory extends SSLSocketFactory {

SSLContext sslContext = SSLContext.getInstance("TLS");

public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {

super(truststore);

TrustManager tm = new X509TrustManager() {

public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

}

public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

}

public X509Certificate[] getAcceptedIssuers() {

return null;

}

};

sslContext.init(null, new TrustManager[] { tm }, null);

}

@Override

public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {

return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);

}

@Override

public Socket createSocket() throws IOException {

return sslContext.getSocketFactory().createSocket();

}

Add this function inside your MainActivity class to create a httpClient using custom socket factory. As shown in the below code.

    public HttpClient getNewHttpClient() {
        try {
            KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
            trustStore.load(null, null);

            MySSLSocketFactory sf = new MySSLSocketFactory(trustStore);
            sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

            HttpParams params = new BasicHttpParams();
            HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
            HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

            SchemeRegistry registry = new SchemeRegistry();
            registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
            registry.register(new Scheme("https", sf, 443));

            ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
            return new DefaultHttpClient(ccm, params);
        } catch (Exception e) {
            return new DefaultHttpClient();
        }
    }

public HttpClient getNewHttpClient() {

try {

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());

trustStore.load(null, null);

MySSLSocketFactory sf = new MySSLSocketFactory(trustStore);

sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

HttpParams params = new BasicHttpParams();

HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);

HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

SchemeRegistry registry = new SchemeRegistry();

registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));

registry.register(new Scheme("https", sf, 443));

ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

return new DefaultHttpClient(ccm, params);

} catch (Exception e) {

return new DefaultHttpClient();

}

Then Run an Async task for https post like this.

 //Async tak to UserToken
    class getToken extends AsyncTask<String, Void, String> {

        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(MainActivity.this);
            pDialog.setMessage("Please wait. Logging in...");
            pDialog.show();
        }

            @Override
            protected String doInBackground(String... arg0) {

                try {
                    //Post Username and password
                    HttpClient httpclient = getNewHttpClient();
                    HttpPost httppost = new HttpPost(BASEURL);
                    List<BasicNameValuePair> nameValuePairs = new ArrayList<>(1);
                    nameValuePairs.add(new BasicNameValuePair("Email", arg0[0]));
                    nameValuePairs.add(new BasicNameValuePair("Password", arg0[1]));

                    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                    // Execute HTTP Post Request
                    HttpResponse response = httpclient.execute(httppost);
                    HttpEntity entity = response.getEntity();
                    String responseString = EntityUtils.toString(entity, "UTF-8");
                    pDialog.dismiss();
                    Log.d("Results ", "tryLogin: "+responseString);
                    return responseString;
                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                } catch (ClientProtocolException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }

                return null;
            }
        }

//Async tak to UserToken

class getToken extends AsyncTask<String, Void, String> {

protected void onPreExecute() {

super.onPreExecute();

pDialog = new ProgressDialog(MainActivity.this);

pDialog.setMessage("Please wait. Logging in...");

pDialog.show();

}

@Override

protected String doInBackground(String... arg0) {

try {

//Post Username and password

HttpClient httpclient = getNewHttpClient();

HttpPost httppost = new HttpPost(BASEURL);

List<BasicNameValuePair> nameValuePairs = new ArrayList<>(1);

nameValuePairs.add(new BasicNameValuePair("Email", arg0[0]));

nameValuePairs.add(new BasicNameValuePair("Password", arg0[1]));

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request

HttpResponse response = httpclient.execute(httppost);

HttpEntity entity = response.getEntity();

String responseString = EntityUtils.toString(entity, "UTF-8");

pDialog.dismiss();

Log.d("Results ", "tryLogin: "+responseString);

return responseString;

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return null;

}

And if you want to do an https Get request. See the code below

   class getUserToken extends AsyncTask<String, Void, String> {

        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(Profile.this);
            pDialog.setMessage("Please wait. Loading data...");
            pDialog.show();
        }

        @Override
        protected String doInBackground(String... arg0) {

            try {
                // get user token
                HttpClient httpclient = getNewHttpClient();
                HttpGet httpget = new HttpGet(BASEURL);

                // Execute HTTP get Request
                HttpResponse response = httpclient.execute(httpget);
                HttpEntity entity = response.getEntity();
                String responseString = EntityUtils.toString(entity, "UTF-8");
                pDialog.dismiss();
                Log.d("Results ", "get login : "+responseString);
                return responseString;
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

            return null;
        }
    }

class getUserToken extends AsyncTask<String, Void, String> {

protected void onPreExecute() {

super.onPreExecute();

pDialog = new ProgressDialog(Profile.this);

pDialog.setMessage("Please wait. Loading data...");

pDialog.show();

}

@Override

protected String doInBackground(String... arg0) {

try {

// get user token

HttpClient httpclient = getNewHttpClient();

HttpGet httpget = new HttpGet(BASEURL);

// Execute HTTP get Request

HttpResponse response = httpclient.execute(httpget);

HttpEntity entity = response.getEntity();

String responseString = EntityUtils.toString(entity, "UTF-8");

pDialog.dismiss();

Log.d("Results ", "get login : "+responseString);

return responseString;

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return null;

}

As we all know one of the new feature announced in Ubuntu 16.04 is moving your sidebar or launcher position. In this article i will share the command that will help you to move your launcher position to bottom.

Just use the below command to move your launcher to bottom of the screen.

gsettings set com.canonical.Unity.Launcher launcher-position Bottom

1	gsettings set com.canonical.Unity.Launcher launcher-position Bottom

And if you want to move the launcher to its original position to its original position (left) use the below command.

gsettings set com.canonical.Unity.Launcher launcher-position Left

1	gsettings set com.canonical.Unity.Launcher launcher-position Left

Hope this helps. Thank you. 🙂

In this tutorial, we will be looking at how to load images from server in to android grid view. Once you complete this tutorial, your application will look like this.

Screenshot_2016-06-02-23-44-47

Lets call this application as a Movie Database. This will display list of movies and the name in a grid view.

1 . Creating Database

First of all lets create a database content_db. Create a new file named content_db.sql and copy and paste the below code and save it.

-- phpMyAdmin SQL Dump

SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";


/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;

Now import the this file in to the database you have created.

2. Creating an API

Now you have the database ready, lets create an API to get all movies using PHP.

Copy the below code and save it in to file named content_db_getAllMovies.php in localhost location ( in my case its /var/www/html/). you can save it in your localhost location.

<?php


class Movies{



	public function getallmovies(){
		$db = new Db();

		$results = $db->getmovies();
		echo json_encode($results);
	
	}

}


class Db {
	public $connection;

	private $servername = "localhost";
	private $username   = "root";
	private $password   = "sathyabaman";
	private $database   = "content_db";


	public function connect(){
		try {
			$this->connection = new PDO("mysql:host={$this->servername};dbname={$this->database}", $this->username, $this->password);
			// set the PDO error mode to exception
			$this->connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    		$this->connection->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
			//$this->logger->writeLog('MySQL Connection Success');
			return $this->connection;
		} catch(PDOException $e) {
			$this->logger->writeLog('MySQL Connection failed');
			return false;
		}
	}

	public function getmovies(){
		$this->connect();
				$query = "SELECT id, title AS name, poster AS image FROM tb_movies";
				$stmt = $this->connection->prepare($query);
				$result = $stmt->execute();
				$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
				return $results;
	}

}


$movies = new Movies();
$movies->getallmovies();

<?php

class Movies{

public function getallmovies(){

$db = new Db();

$results = $db->getmovies();

echo json_encode($results);

}

class Db {

public $connection;

private $servername = "localhost";

private $username = "root";

private $password = "sathyabaman";

private $database = "content_db";

public function connect(){

try {

$this->connection = new PDO("mysql:host={$this->servername};dbname={$this->database}", $this->username, $this->password);

// set the PDO error mode to exception

$this->connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$this->connection->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

//$this->logger->writeLog('MySQL Connection Success');

return $this->connection;

} catch(PDOException $e) {

$this->logger->writeLog('MySQL Connection failed');

return false;

}

public function getmovies(){

$this->connect();

$query = "SELECT id, title AS name, poster AS image FROM tb_movies";

$stmt = $this->connection->prepare($query);

$result = $stmt->execute();

$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

return $results;

}

$movies = new Movies();

$movies->getallmovies();

Make sure to change your database configuration as per your database credentials, In the above file.

    private $servername = "localhost";
	private $username   = "root";
	private $password   = "sathyabaman";
	private $database   = "content_db";

private $servername = "localhost";

private $username = "root";

private $password = "sathyabaman";

private $database = "content_db";

3. Creating an Android application

Now lets create a new android application called MovieDatabase, when you create an new application in android studio it will automatically create a new activity called MainActivity. You can change it to anything you want, but i recommend to leave it as it is for this tutorial.

4. Creating Styles and Drawable

Copy and paste the below code inside /res/values/colors.xml file.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#3F51B5</color>
    <color name="colorPrimaryDark">#303F9F</color>
    <color name="colorAccent">#FF4081</color>

    <color name="colorClear">#FFFF</color>
</resources>

<?xml version="1.0" encoding="utf-8"?>

</resources>

save and close it.

Now create a new file called grid_color_selector.xml inside /res/drawable/ folder and then copy and paste the below code.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@color/colorPrimary" android:state_pressed="true" />
    <item android:drawable="@color/colorPrimary" android:state_selected="true" />
    <item android:drawable="@color/colorClear" />

</selector>

<?xml version="1.0" encoding="utf-8"?>

</selector>

save and close it.

5. Creating Layout files

Now create a new file called grid_item_layout.xml in your /res/layout/ folder and copy and paste the below code.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:background="@drawable/grid_color_selector"
    android:orientation="vertical"
    android:padding="5dp">

    <ImageView
        android:id="@+id/grid_item_image"
        android:layout_width="100dp"
        android:scaleType="fitCenter"
        android:layout_height="100dp" />

    <TextView
        android:id="@+id/grid_item_title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"
        android:ellipsize="marquee"
        android:gravity="center"
        android:maxLines="2"
        android:textSize="12sp" />

</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="5dp"

android:background="@drawable/grid_color_selector"

android:orientation="vertical"

android:padding="5dp">

<ImageView

android:id="@+id/grid_item_image"

android:layout_width="100dp"

android:scaleType="fitCenter"

android:layout_height="100dp" />

<TextView

android:id="@+id/grid_item_title"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginTop="5dp"

android:ellipsize="marquee"

android:gravity="center"

android:maxLines="2"

android:textSize="12sp" />

</LinearLayout>

save and close it.

Now open your activity_main.xml which is located in /res/layout/ folder. open the file and copy and paste the below code.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#f0f0f0">

    <GridView
        android:id="@+id/gridView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:columnWidth="100dp"
        android:drawSelectorOnTop="true"
        android:gravity="center"
        android:numColumns="auto_fit"
        android:stretchMode="columnWidth"
        android:verticalSpacing="5dp"
        android:focusable="true"
        android:clickable="true"/>

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/progressBar"
        android:layout_centerInParent="true"
        android:visibility="gone"/>
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="#f0f0f0">

<GridView

android:id="@+id/gridView"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_margin="5dp"

android:columnWidth="100dp"

android:drawSelectorOnTop="true"

android:gravity="center"

android:numColumns="auto_fit"

android:stretchMode="columnWidth"

android:verticalSpacing="5dp"

android:focusable="true"

android:clickable="true"/>

<ProgressBar

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/progressBar"

android:layout_centerInParent="true"

android:visibility="gone"/>

</RelativeLayout>

Save and close it.

6. Java classes

create a new java file named GridViewAdapter.java inside your package and copy and paste the below code. make sure to change your package name.

package baman.lankahomes.lk.moviedatabase;

        notifyDataSetChanged();
    }

    @Override

        View row = convertView;
        ViewHolder holder;

        if (row == null) {
            LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);

save and close it.

Now create another new file called GridItem.java inside your package and then copy and paste the below code.

package baman.lankahomes.lk.moviedatabase;

    public String getId(){ return id; }


    public String getImage() {
        return image;
    }

    public void setImage(String image) {
        this.image = image;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;

public void setImage(String image) {

this.image = image;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

save and close it.

Now open you MainActivity.java class and make sure it looks like the below code.

save and close it.

7. Create a second activity

Now we need to create a new activity to be viewed when ever the movie is clicked. So lets create a new activity called DetailsActivity using your android studio.

8. Modify Manifest file.

This application need a internet connection to get data from the server, therefore it is necessary to add that permission to the manifest file. As shown in the below code.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="baman.lankahomes.lk.moviedatabase">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".DetailsActivity"
                  android:label="@string/details"></activity>
    </application>

</manifest>

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="baman.lankahomes.lk.moviedatabase">

<uses-permission android:name="android.permission.INTERNET" />

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:supportsRtl="true"

android:theme="@style/AppTheme">

<intent-filter>

</intent-filter>

</activity>

<activity android:name=".DetailsActivity"

android:label="@string/details"></activity>

</application>

</manifest>

9. Gradle Build

It is important to tell the gradle how to build the application. Note this application is using HttpClient package which is no more supported in android studio. Therefore its is very important how you set the build.gradle file.

Make sure your build.gradle file looks exactly as shown in the below code snippet.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "baman.lankahomes.lk.moviedatabase"
        minSdkVersion 8
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    testCompile 'junit:junit:4.12'
    compile 'com.squareup.picasso:picasso:2.5.2'
}

apply plugin: 'com.android.application'

android {

compileSdkVersion 23

buildToolsVersion "23.0.2"

useLibrary 'org.apache.http.legacy'

defaultConfig {

applicationId "baman.lankahomes.lk.moviedatabase"

minSdkVersion 8

targetSdkVersion 23

versionCode 1

versionName "1.0"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

compile 'com.android.support:appcompat-v7:22.2.0'

testCompile 'junit:junit:4.12'

compile 'com.squareup.picasso:picasso:2.5.2'

}

make sure to set your applicationId. That’s it. compile the application and run it on your device or emulator. It should work fine.

10. Happy coding.

I have tried the us diversity program for the past three years, but i have not found lucky enough. In this article i will give you some information and screenshots of the US diversity program.

Usually the us diversity program opens for application in the period of October and November. Usually they accept application for around 30 days.
