Bound Service Example in Android Studio 2.1.2

Code Verified on-
Android Studio 2.1.2

Step1: main_activity.xml
Take a new Project and open activity_main.xml file. Coding will be like following.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:orientation="vertical"
    tools:context="androidhubb.setvices.MainActivity"
    android:layout_margin="16dp"
    android:gravity="center_vertical">

   <Button
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:text="Start Services"
       android:onClick="onStart"/>

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Stop Services"
        android:onClick="onStop"/>
</LinearLayout>

Step 2:- To start a Bound Service we have to take another java file MyService.java | code will be like..

package androidhubb.boundservice;

import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.support.annotation.Nullable;

/** * Created by Supriya on 8/24/2016. */

public class MyService extends Service {
    MediaPlayer mp;
    @Nullable    @Override   

 public IBinder onBind(Intent intent) {
        return null;
    }

    @Override    

public void onCreate() {
        super.onCreate();
        mp=MediaPlayer.create(this,R.raw.sanam);
        mp.setLooping(true);
    }

    @Override    

public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        mp.start();
    }

    @Override   

 public void onDestroy() {
        super.onDestroy();
        mp.stop();
    }
}

3. MainAvtivity.java

package androidhubb.boundservice;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    @Override    
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void onStart(View v){
        startService(new Intent(getApplicationContext(),MyService.class));
    }
    public void onStop(View v){
        stopService(new Intent(getApplicationContext(),MyService.class));
    }
}
