Google map fragment crashes when clicked twice or changed fragment

StackOverflow https://stackoverflow.com/questions/23316426

Question

I have a fragment navigation issue. I made a MainActivity with a fragment using GoogleMap. With a NavigationDrawer, I choose to go to the GoogleMapFragment, it works, but if I change the fragment, and want to go back to my GoogleMapFragment already initiated, it crashs.

Solution

you should override this method: (it destroys the google_map_fragment correctly after you clicked in another fragment ..)

  public void onDestroyView() 
     {
        super.onDestroyView(); 
        Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));  
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
    }

you have to override this method aswell if you want to initialize the map fragment everytime :)

@Override
public void onPause(){
super.onPause();
if(googleMap != null) {   
    googleMap = null;
  {
}
