Auto App start on Boot Completion

You can start your application when the device starts again thru BroadcastReceiver:

public class PhoneStateReceiver extends BroadcastReceiver{

   

    @Override

    public void onReceive(final Context context, Intent intent) {

       

        if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){

            Intent launch = new Intent(context, ActivityToLaunch.class);

            launch.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

            context.startActivity(launch);

        }

    }

}

In your manifest add this:

<receiver android:name=".receiver.PhoneStateReceiver">

    <intent-filter>

        <action android:name="android.intent.action.BOOT_COMPLETED" />

    </intent-filter>

</receiver>   

Add permission:

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