MapFragment or MapView getMap() returns null on Lollipop

Question

I\'ve been using Google Maps API v2 for a long time on Android 4.x versions without a problem. Now I installed latest Lollipop build on my Nexus devices (5 and 7) trying to

It looks like this might be an issue with a targetSdkVersion of 21: https://code.google.com/p/android-developer-preview/issues/detail?id=1947

However, switching to getChildFragmentManager() worked for me:

findFragmentById for SupportMapFragment returns null in Android Studio

Google now made a more convenient way to get the map using the following method

    myMapFragment.getMapAsync(new OnMapReadyCallback) {
         @Override
         public void onMapReady(GoogleMap googleMap) {
             myMap = googleMap;
         }
    });

I had exactly the same problem but this is what worked for me:

Replace this...

GoogleMap map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

with this...

GoogleMap map = getMapFragment().getMap();

then slip this bad boy in and give it a whirl...

private MapFragment getMapFragment() {
    FragmentManager fm = null;

    Log.d(TAG, "sdk: " + Build.VERSION.SDK_INT);
    Log.d(TAG, "release: " + Build.VERSION.RELEASE);

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
        Log.d(TAG, "using getFragmentManager");
        fm = getFragmentManager();
    } else {
        Log.d(TAG, "using getChildFragmentManager");
        fm = getChildFragmentManager();
    }

    return (MapFragment) fm.findFragmentById(R.id.map);
}

Have you tried isGooglePlayServicesAvailable to check why its returning null? null has many reasons on getmap, try using this to check why its giving null
