how to force stop android service programmatically

Question

I make tow buttons one to start service and other to stop it when I press stop button notify me service is stopped but actually it still working in the background i use timer in my onStartCommand() method repeat every second is it the reason..? and how to force stop service immediately.

public int onStartCommand(Intent intent, int flags, int startId) {
    Toast.makeText(getApplicationContext(),"start..",Toast.LENGTH_SHORT).show();
    new Timer().scheduleAtFixedRate(new TimerTask() {

        private Handler handler = new Handler(){
            @Override
            public void dispatchMessage(Message msg) {
                Toast.makeText(getApplicationContext(),""+(counter+=1),Toast.LENGTH_SHORT).show();
            }
        };
        @Override
        public void run() {
            handler.sendEmptyMessage(0);
        }
    },0,1000);


    return START_STICKY;
}

`

and my buttons action :-

public void btnStart(View view){

    startService(new Intent(MainActivity.this,MyService.class));

}
public void btnStop(View view){

   stopService(new Intent(MainActivity.this,MyService.class));
}

i found answer ..! the answer is must cancel timer and timerTask in onDestroy method

Please put in your Service class and how you call your service so we can troubleshoot :) — Brandon, May 01 '19 at 01:16

Here's a simplified description of how to stop services :

stopSelf() is used to always stop the current service.

stopSelf(int startId) is also used to stop the current service, but only if startId was the ID specified the last time the service was started.

stopService(Intent service) is used to stop services, but from outside the service to be stopped.

please replace

return START_STICKY;

by

return START_NOT_STICKY;

Difference:

START_STICKY

the system will try to re-create your service after it is killed

START_NOT_STICKY

the system will not try to re-create your service after it is killed

So why don't you just create a function inside you service that stop the timer , and then call it after you stop the service ? – ismail alaoui May 02 '19 at 13:35

If you intend to stop a service you start you should call stopService(Intent) ex:

Intent intent = new Intent(MainActivity.this, YourService.class);
stopService(intent);

I use this cod but also still running – Noah Mohamed May 01 '19 at 03:32
you should override the onDestory() method and stop your timer on it. – Shalan93 May 01 '19 at 14:00
