Deepank Mehta :
I have background services which captures location from the users device but when I stop it using the stopService method from anther activity it does not stop and due to this the app crashes as the app is not able to send the lat long to server.
Note - I have a retrofit post request which is made to the server when the location is not null and also when I click on the stop service button in main activity the notification disappears from the device but actually the service does not stop and the location is logged in the logcat. But it is not posted to the server due to this timeout error is received and app crashes.
Here is the service class:

Nensi Kasundra :
Start service like below:
Intent intent = new Intent(this, LiveLocationService.class);
intent.putExtra("empCode", empCode);
intent.putExtra("year", year);
intent.putExtra("month", month);
intent.putExtra("date", dateToday);
startService(intent);
ContextCompat.startForegroundService(this, intent)
Stop service like below:
stopService(new Intent(this, LiveLocationService.class));
Service onDestory() method like below:
@Override
public void onDestroy() {
super.onDestroy();
// Stop location udates
//hide your notification here
}
