Здравствуйте, у меня проблема с фрагментом OnDestroy при интеграции карт Google во фрагмент пейджера просмотра. проблема возникает всякий раз, когда фрагмент карты уничтожается, и я пытаюсь уничтожить фрагмент контейнера. По крайней мере, я так считаю.
Поэтому всякий раз, когда есть причина уничтожить основное действие, приложение получает прикрепленную ошибку. (выйти из системы, нажать кнопку «Назад» и т. д.).

Фрагмент карты , метод OnDestroy, который я использовал на основе других предложений stackoverflow, помогает при изменении вкладок, однако выдает ошибку.
package com.user;
// MAP POINTS AND BUS_POINTS ARE STILL UNTESTED
public class Fragment_Map extends Fragment implements LocationListener {
// ...
private GoogleMap map;
SqlHandler sqlHandler;
private BroadcastReceiver mMessageReceiver;
private LatLng myLocation;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_map, null, false);
sqlHandler = new SqlHandler(getActivity());
initilizeMap();
return v;
}
private void initilizeMap() {
if (map == null) {
map = ((SupportMapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (map == null) {
Toast.makeText(getActivity().getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
public void onDestroyView() {
LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(mMessageReceiver);
super.onDestroyView();
Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.remove(fragment);
ft.commit();
}
}
