Question

У меня есть приложение, отображающее текущее местоположение пользователя на карте Google, приложение работает в эмуляторе (хотя оно не показывает местоположение), однако оно сбой в реальном устройстве. Здесь ошибка я получаю

почему Google Map пустой? Я использую API в моем мета ДЭТА

Изменить Вас или создать, чтобы начать с

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

Удалить дополнительные setContentView вызовы.

Использование getMapAsyc для обработки асинхронной инициализации карты:

SupportMapFragment supportMapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap); 
supportMapFragment.getMapAsync(new OnMapReadyCallback(){ 
    @Override 
    public void onMapReady(final GoogleMap map) { 
     map.setMyLocationEnabled(true); 
    } 
});
