Answer 1

Я заметил, что вы не добавили защиту для Служб Google Play, Google Maps V2 api требует, чтобы это выполнялось.

Возможно, проблема связана с тем, что службы Google Play не поддерживаются в AVD. Попробуйте запустить устройство.

может быть, это может помочь

Missing Google Play Services from AVD

Answer 2

Вы должны расширить FragmentActivity чем активность.

Используйте это в своей деятельности: map = ((SupportMapFragment) getSupportFragmentManager(). FindFragmentById (R.id.map)). GetMap();

И в XML в фрагмент тега написать это:

класс = "com.google.android.gms.maps SupportMapFragment."
