I have a service which returns START_STICKY on #onStartCommand() and it is being started in my MainActivity's #onCreate() method. When i close my app, Service is being destroyed and it starts itself again. However, when it starts itself, ActivityManager can't find it. So there are 2 instance of my service running..

I use this code to check is service dead, it returns true everytime even if it lives after service starts itself.

public static boolean isServiceDead(Context context) {
    final ActivityManager am = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE);
    for (ActivityManager.RunningServiceInfo runningServiceInfo : am.getRunningServices(Integer.MAX_VALUE))
        if (runningServiceInfo.service.getClassName().equals(LockerService.class.getName()))
            return false;

    return true;
}

what are you doing in your activity on destroy ? i mean "When i stop my Activity" ? – Quick learner Jan 03 '19 at 11:32
I'm doing nothing on destroy. When I close the app, service is being destroyed and creates itself again because of START_STICKY @Quicklearner edited question. – melianor Jan 03 '19 at 11:33
which device are you using for testing ? – Quick learner Jan 03 '19 at 11:41
Android Emulator API 27 @Quicklearner – melianor Jan 03 '19 at 11:55
please test it on real device , stock android and Customized OS devices and check the behaviour – Quick learner Jan 03 '19 at 12:10
its same on nexus 5 @Quicklearner – melianor Jan 03 '19 at 12:31
In your `isServiceDead()` method, add some debug logging in the `for` loop and output the value that `getClassName()` returns for each `Service` it finds. That may help you find the problem. – David Wasser Jan 03 '19 at 15:27
Yes, i have tried it. When I start service with startService() command, for loop prints my service, but after it destrorys and starts itself, for loop prints nothing @DavidWasser – melianor Jan 03 '19 at 15:58
How do you know your Servicecis restarted? Do you know for sure your Service is running? Hiw? – David Wasser Jan 03 '19 at 17:32
I'm logging in onCreate method, it's being created @DavidWasser – melianor Jan 03 '19 at 18:03
Just being created does not mean it is running. `onStartCommand()` must be called and depending on the return value it will either be running or not. – David Wasser Jan 04 '19 at 12:28
You call also use `adb shell dumpsys activity services` to get more information about running `Services`. – David Wasser Jan 04 '19 at 12:33
