stop IntentService from Activity

问题:

I need help with this situation:

1. I have activity, what starts IntentService.
2. Service do some job in while cycle and sleep for some time.
3. Main cycle of service is endless, so I need to stop it from activity again.

4. I must be able to end activity, start it again and stop IntentService from new "instance" of activity.

   public class MyService extends IntentService {
   
       public MyService()
       {
           super("MyService");
       }
   
       public MyService(String name) {
           super(name);
       }
   
       @Override
       protected void onHandleIntent(Intent intent) {
           Log.d("SERVICE", "start");
   
           while(true)
           {
               SystemClock.sleep(1000);
               Log.d("SERVICE", "tick");
           }
       }
   
       @Override
       public void onDestroy() {
           Log.d("SERVICE", "end");
           super.onDestroy();
       }
   

...

Intent intent = new Intent(getApplicationContext(), MyService.class);
startService(intent);       

I tried calling stopService(), but it's not working. Is there any solution how to do this? Thanks in advance.

IMHO, this is an inappropriate use of IntentService. Please create a regular Service, with your own background thread that you manage yourself.

Create a regular Service, with your own background thread that you manage yourself. For example, you could use a ScheduledExecutorService instead of your sleep() loop, using shutdown() or shutdownNow() in the service's onDestroy().
