Я разработал приложение, которое отображает MapView в основном действии (MapActivity), и это представление карты содержит наложения, при нажатии на которые открывается всплывающее окно с ViewPager и фрагментами внутри. Я успешно реализовал это, вызвав другое действие, используя FragmentActivity во всплывающем окне с помощью окна просмотра, но оно приостанавливает мой MapActivity, чего я не хочу. Однако это решение не вызывает IntentReceiver leaks.
Другим моим решением было изменить MapActivity на FragmentActivity, и вызов всплывающего окна с помощью окна просмотра работает очень хорошо. Однако при закрытии активности срабатывает IntentReceiver leaks. Погуглил и обнаружил, что решение этой проблемы включает отмену регистрации получателей намерений по методу onDestroy, но я не зарегистрировал ни одного.
Утечки NetworkConnectivityListener$ConnectivityBroadcastReceiver & maps.FSTileCache. Кстати, я использую библиотеку mapquest. И я тоже использую библиотеки совместимости.
Вот код:
Использование MapActivity
public class MyMapActivity extends MapActivity {

}
TrafficProfilePopUpActivity (всплывающее окно с окном просмотра и фрагментами)

Как я могу решить эту проблему?
