Google map not showing in android activity?

Question

In my android app I want to have a MainActivity with a google map occupying the entire screen.

My problem is that the google map does not display a map, only the go

Google maps likes to get the different activity lifecycle states. So you should send it: map_view.onCreate(savedInstanceState) and map_view.onResume(). It also likes onPause(), onLowMemory(), onSaveInstanceState(outState), onDestroy() if they occur.
