I'm working on an android app with an advanced integration of Google Maps API V2. I'm using SupportFragment and everything worked fine until I started to put the map in an further child fragment - there is a deep fragment hierarchy:
SplitViewFragment->RightChildFragment->ViewPagerFragment->SupportMapFragment
I want to achieve a special layout for tablets, so it is not possible to remove one fragment level.
So far, so good - everything is working very well on Android 4.3+ Devices but on lower API levels, the map fragment always remains blank/transparent - the google logo and the zoom controls are visible. There is no logcat error. Google Map is working on the same device when I remove one nested fragment; so it's not an authentication problem, as often described.
I also tried to initialize the MapFragment with zOrderOnTop without success:
GoogleMapOptions options = new GoogleMapOptions();
options.zOrderOnTop(true);
SupportMapFragment mapFragment = SupportMapFragment.newInstance(options);
I spent two complete days on trying to find an answer for this problem and did an extensive research - without success.
I'm so looking forward to your answers. Thanks a million!
Unbelievable - I have an animation view in hierarchy with hardware acceleration - I removed the acceleration for API Levels < 18 as there is a problem with clipPath:
setLayerType(View.LAYER_TYPE_SOFTWARE, null);
I fixed it by removing the deactivation of the hardware acceleration. I've to find another solution to be able to deactive the hardware acceleration.
Thanks a lot for your help.
