        mTimer = new Timer();
        mTimer.schedule(timerTask, 2000, 2 * 1000);

    }

    @Override

        } catch (Exception e) {

            if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            Log.i("Service Stops", "Ohhhhhhh");
            context.startService(new Intent(context, ServiceTest.class));;

Answer 1

In theory, this is not possible; according to the Android security model.

As Panaj Kumar points out in the comments:

When user does force stop, means he does not want to run this application (any component). he is not interested anymore, and this is rights of user. SO android does not gives a way to keep running your service, even after forced close your app.

Android will prevent the app from restarting using the START_STICKY flag, and will disable the RECEIVE_BOOT_COMPLETED receiver. The system will also disable all Alarms that have been set for this app.

Before the system will allow the app to run again, the user must run an Activity of the app themselves.

---

That said, it seems that certain apps are still able to break the rules in this way. This should be considered incorrect and would be taking advantage of a security hole, however it shows that it is still possible, even on KitKat.

The Discovery Insure driving app seems to be able to restart itself when it has been force stopped, and will restart on boot:

• Discovery Insure Driving Challenge on Play Store

However, this functionality should not be relied on - hopefully this security flaw will be fixed in future system updates.

Answer 2

Write this on in your OnCreate of the main launching activity

if(!isMyServiceRunning(ServiceClass.class))
    context.startService(new Intent(context.getApplicationContext(),ServiceClass.class));

here is the running service check function

private boolean isMyServiceRunning(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}

and Create your service with this architecture.Observe the return START_STICKY

public class ServiceClass extends IntentService {
    public ServiceClass()
    {
        super("null");
    }
    public Context context;
    public Intent intent;
    public Date currentTime;

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

    @Override
    protected void onHandleIntent(@Nullable Intent intnt) {

        currentTime = Calendar.getInstance().getTime();
        context = getApplicationContext();
        this.intent = intnt;
        Log.d("ServiceClass","Service class running "+ currentTime);

    }
}
