            Calendar cal = Calendar.getInstance();
            // start 30 seconds after boot completed

Answer 1

my problem solve with

Autostart.java

public class Autostart extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Intent alarm = new Intent(context, AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarm, 0);
        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

        System.out.println("[*******-----------> Autostart  <-----------*******]");

        alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), 15000, pendingIntent);

    }

}

AlarmReceiver.java

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent background = new Intent(context, NewsServiceReceiver.class);
        context.startService(background);
    }

}

NewsServiceReceiver.java

public class NewsServiceReceiver extends Service {

    private boolean isRunning;
    private Context  contex;
    private Thread backgroundTread;

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

    @Override
    public void onCreate(){
        this.contex = this;
        this.isRunning = false;
        this.backgroundTread = new Thread(myTask);

    }

    private Runnable myTask = new Runnable() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            System.out.println("[*******-----------> BACKGROUND  <-----------*******]");

            //------------My Code Here--------------

            stopSelf();
        }
    };


    @Override
    public void onDestroy(){
        this.isRunning = false;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if(!this.isRunning){
            this.isRunning = true;
            this.backgroundTread.start();
        }
        return START_STICKY;
    }

}

SplashActivity.java -> May first Activity when app run

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
-
        this.context=this;
        Intent alarm = new Intent(this.context, AlarmReceiver.class);
        boolean alarmRunning = (PendingIntent.getBroadcast(this.context, 0, alarm, PendingIntent.FLAG_NO_CREATE) != null);
        if(alarmRunning == false){
            PendingIntent pendingIntent = PendingIntent.getBroadcast(this.context, 0, alarm, 0);
            AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
            alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), 15000, pendingIntent);
        }
}
