You need to add "android:process=:any_name" in the manifest under the inside the service attributes.

For example,

      <service android:name=".MyService"
        android:process=":MyService"
        android:enabled="true"/>

Below is the code of my Service class.

public class MyService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}


@Override
public void onCreate() {
    super.onCreate();
    Log.e("onCreate", "onCreate");
    Toast.makeText(AppController.getInstance(),"Created",Toast.LENGTH_SHORT).show();
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.e("servicedestroy", "servicedestroy");
    Toast.makeText(AppController.getInstance(),"service destroy",Toast.LENGTH_SHORT).show();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Timer t = new Timer();
    t.scheduleAtFixedRate(new TimerTask() {
                              @Override
                              public void run() {

                                  new Handler(Looper.getMainLooper()).post(new Runnable() {
                                      @Override
                                      public void run() {
                                          Toast.makeText(AppController.getInstance(),"Running",Toast.LENGTH_SHORT).show();
                                      }
                                  });


                              }

                          },
            0,
            5000);

    return START_STICKY;
}

@Override
public void onTaskRemoved(Intent rootIntent) {
    Intent restartServiceIntent = new Intent(getApplicationContext(), this.getClass());
    restartServiceIntent.setPackage(getPackageName());

    PendingIntent restartServicePendingIntent = PendingIntent.getService(getApplicationContext(), 1, restartServiceIntent, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    alarmService.set(
            AlarmManager.ELAPSED_REALTIME,
            SystemClock.elapsedRealtime() + 1000,
            restartServicePendingIntent);

    super.onTaskRemoved(rootIntent);
}

}

On some devices (notably Xiaomi, Huawei, Lenovo) you need to add your app to a list of "protected apps" or "apps that are allowed to run in the background". If your app isn't in the list, Android will NOT automatically restart your Service, even if you have returned START_STICKY from onStartCommand(). This is a "battery saving feature" that unfortunately makes a lot of problems for developers!

Look in the Android settings under Power management, Security or Apps for these settings.

Code might help you in HourlyService class onStartCommand method returns START_STICKY

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return START_STICKY;
}

Inside Activity

 private HourlyService mHourlyService;
private ServiceConnection mServiceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        // We've bound to LocalService, cast the IBinder and get LocalService instance
        LocalBinder binder = (LocalBinder) iBinder;
        mHourlyService = binder.getService();
        mBound = true;
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        mBound = false;
    }
};

@Override
protected void onStart() {
    super.onStart();
    // Bind to LocalService
    Intent intent = new Intent(this, HourlyService.class);
    bindService(intent, mServiceConnection, Context.BIND_AUTO_CREATE);
}

@Override
protected void onStop() {
    super.onStop();
    unbindService(mServiceConnection);
    mBound = false;
}
