Google Maps API 17で強制終了

Question

（Android Studioを使用して）ナビゲーションドロワーで簡単なマップアプリケーションを作成しようとしていますが、私は奇妙なケースに直面しています。私はVirtual Device API 24（実際のMarshmallowデバイス）で試してみましたが、正常に動作します（ログcatではエラーメッセージなし）。

しかし、Virtual Device API 17（実際のKitkat 4.4.2デバイス）を試したときに、アプリケーションがエラーをスローしました。

import com.google.android.gms.maps.model.MarkerOptions; 

import dev.dtgultom.ontelbike.R; 

public class LocationFragment extends Fragment implements OnMapReadyCallback { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.fragment_location,container,false); 
     return view; 
    } 

    @Override 
    public void onViewCreated(View view, Bundle savedInstanceState) { 
     super.onViewCreated(view, savedInstanceState); 
     MapFragment fragment = (MapFragment) getChildFragmentManager().findFragmentById(R.id.map); 
     fragment.getMapAsync(this); 
    } 

    @Override 
    public void onMapReady(GoogleMap googleMap) { 
     LatLng stockholm = new LatLng(59.3293, 18.0686); 
     googleMap.addMarker(new MarkerOptions().position(stockholm).title("User Position")); 
     googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(stockholm, 15)); 
    } 
}

をテストするとき、私はすでに解決策を試してみました：

しかし、それは動作しません。私の本当のMarshmallowデバイスと仮想デバイスAPI 24で正常に動作し、私の実際のkitkat（4.4.2）デバイスと仮想デバイスAPI 17でエラーが発生します。

Answer 1

あなたのコードで波紋エフェクトを使用している場合。

はこれを追加： -

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
     //and ripple button (Call some material design APIs here) 
    } 
else { 
    //add simple button/image (Implement without material design) 
    } 

Answer 2

私は答えを見つけました。私は、supportMapFragmentまたはMapFragmentの代わりにMapViewを使用します。
