I do not want to use or extend SupportMapFragment or MapFragment. I have my own base class with a bunch of code in it.

The documentation clearly states that when someone uses MapView by itself, all corresponding lifecycle methods (onCreate() onResume() etc.) should be called.

Most of the lifecycle methods in a Fragment are similar to an Activity but when I switch back and forth between my Fragment I eventually get an obfuscated NPE in onDestroy() or in onResume() methods.

All the samples provided use an Activity with a MapView but not a custom Fragment.

Has someone done that already? Can you provide sample code of a MapView in your own Fragmentclass?

    I succeeded in including a MapView (v2) in a custom Fragment itself embedded in a ViewPager. In my case, the MapView is included in the Fragment layout file. I have had to call lifecycle methods on MapView (onCreate() called onCreateView() from the Fragment), and to call manually MapsInitializer.initialize(context) to avoid a NullPointerException from class BitmapDescriptorFactory (to get the bitmap for markers). This last trick is strange, and I don’t know why the Map system isn’t properly initialized itself without this call, maybe it’s just a bug in the current version …

    In my case I haven’t had any NullPointerException in onResume() or onDestroy().
