Обнаружена утечка службы до onDestroy

У меня есть служба, которая должна быть сохранена до тех пор, пока приложение активно. Поэтому в LoginActivity, когда пользователь не вошел в систему, я вызываю stopService, и когда пользователь входит в систему, я запускаю службу, явно просматривая startService.Обнаружена утечка службы до onDestroy

public class LoginActivity extends BaseActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_login); 

     if (accountHelper.isLoggedIn()) { 
      proceedToMainActivity(); 
     } else if (savedInstanceState == null) { 
      Fragment fragment = LoginFragment.newInstance(); 
      getSupportFragmentManager() 
        .beginTransaction() 
        .add(R.id.LoginContainer, fragment) 
        .commit(); 
     } 
    } 

    public void proceedToMainActivity() { 
     final Intent intent = MainActivity.createIntent(this); 
     intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); 
     startActivity(intent); 
    } 
//... 
}

Тогда в других мероприятиях, я связываю в OnStart и отвязать в OnStop, в службе:

@Override 
public boolean onUnbind(Intent intent) { 
    Timber.d("onUnbind: %s", intent); 
    handler.scheduleStop(KEEP_ALIVE); 
    return false; 
}

Это расписание stopSelf() после keep_alive времени (на данный момент его 500 (полсекунды), но это было нормально для 60000 (одна минута)
Служба уничтожена, когда пользователь уходит из приложения на долгое время и воссоздается успешно, однако после очень короткого времени от onCreate и onBind LeakCanary сообщает об утечке памяти этой службы. Обратите внимание, что ни onUnbind, ни onDestroy не вызывались. LeakCanary дает следующую свалку:

Почему сервис обозначен как утечка? UPD: Я удалил явный запуск/остановку службы и задержку остановки из onUnbind, но утечка остается неизменной.

для предотвращения утечек Я хотел бы предложить регистрации/ссылки на службе в методе OnCreate вашего приложения class.eg MediaUploaderService.StartService (это, MediaUploaderService.START_APP_START), то в вашей службе в onStartCommand методы убедитесь, что вы имеете возвращенное обслуживание. START_STICK, который сообщает ОС, чтобы воссоздать службу после того, как у нее достаточно памяти, и снова вызовите onStartCommand() с нулевым намерением. Это должно помочь решить проблему утечки. См. Также эту ссылку. http://stackoverflow.com/questions/9093271/start-sticky-and-start-not-sticky – Zidane

@ Zidane, это не совсем то, что я искал. На данный момент я удалил явное начало/остановку и задержку остановки службы в onUnbind, так что служба будет уничтожена, если никакая активность не будет привязана к ней быстро. Но утечка остается, возможно, это необходимая утечка для связанных служб. –

Похоже, что это неизбежно с ограниченными услугами. Я показал пример приложения, чтобы продемонстрировать эту проблему. https://github.com/KonstantinBerkow/Android-Bound-Service-Leak
