android - google map ne s'affiche pas sur certains appareils

Question

J'ai testé mon application sur beaucoup de téléphones et cela fonctionne bien et affiche la carte correctement, mais il ne s'affiche pas sur certains appareils. Il est très étrange que les appareils qui n'affichent pas la carte fonctionnent correctement dans d'autres applications utilisant des cartes. Je veux dire, que les appareils montre la carte et fonctionne très bien dans d'autres applications/

voici mon code:

public class Maps extends AppCompatActivity { 
    MapFragment googleMap; 
    GoogleMap Map; 
    Intent locatorService = null; 
    Double lat = 0.0, lon = 0.0; 
    Typeface typeface; 
    int isAvailable = 777; 
    private LatLng location; 
    Boolean forEdit = false; 

    @Override 
    protected void onCreate(@Nullable Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.maps); 

     isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this); 
     typeface = Func.getTypeFace(this); 

     final Bundle bl = getIntent().getExtras(); 
     if (bl != null) { 
      forEdit = true; 
     } 

     if (isAvailable == 0) { 
      googleMap = (MapFragment) getFragmentManager().findFragmentById(R.id.map); 
      googleMap.getMapAsync(new OnMapReadyCallback() { 
       @Override 
       public void onMapReady(GoogleMap googleMap) { 
        Map = googleMap; 

        if (googleMap == null) { 
         Toast.makeText(getApplicationContext(), 
           "نقشه روی گوشی شما قابل نمایش نیست", Toast.LENGTH_SHORT) 
           .show(); 
        }

      ActivityCompat.requestPermissions(Maps.this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1); 
     } else {

     } 


    }

c'est la mise en page xml:

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <fragment 
     android:id="@+id/map" 
     android:name="com.google.android.gms.maps.MapFragment" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

</FrameLayout> 

pourriez-vous me aider? quel est le problème avec mon code?

Vérifiez la réponse de isGooglePlayServicesAvailable, il y a une bonne chance d'obtenir "SERVICE_VERSION_UPDATE_REQUIRED". L'utilisateur doit mettre à jour Google Play Services dans ce cas.

Les services Google Play seront automatiquement mis à jour si d'autres applications Google telles que Google+, GoogleMaps, Google Duo, etc. sont mises à jour.

switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity())) { 
     case ConnectionResult.SUCCESS: 
      googleMap = (MapFragment) getFragmentManager().findFragmentById(R.id.map); 
      googleMap.getMapAsync(new OnMapReadyCallback() { 
      @Override 
      public void onMapReady(GoogleMap googleMap) { 
       map = googleMap; 
       } 
      }); 
      break; 
     case ConnectionResult.SERVICE_MISSING: 
      Toast.makeText(getActivity(), "Google Play Services Missing", Toast.LENGTH_SHORT).show(); 
      break; 
     case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED: 
      //The user has to update play services 
      Toast.makeText(getActivity(), "Update Google Play Services", Toast.LENGTH_SHORT).show(); 
      break; 
     default: 
      Toast.makeText(getActivity(), GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity()), Toast.LENGTH_SHORT).show(); 
    }
