I have given transparent frame over map but still it is flickering. please somebody give me a solution thank you

Answer 1

The transparent frame over the MapView will only solve the black hole problem, the flicker will still happen each time the map re-loads it's resources i.e. when OnCreateView() is called.

Try the solution posted here with adding a MapView in the main Activity and then hiding it once initialized.
