Xamarin Android Google Maps Uygulama haritası boş ve hiçbir hata yok

Question

Monodroid android uygulaması üzerinde çalışıyorum. Google haritalarını bir fragmanla ekledim ancak harita görünmeyecek ve herhangi bir hata atılmayacağım.

Benim Axml kodu:

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

Etkinlik Kodu:

protected async override void OnResume() 
    { 
     base.OnResume(); 


     tblLocations location = Nav.GetAndRemoveParameter<tblLocations>(Intent); 
     LatLng latLng = new LatLng(location.Latitude, location.Longitude); 
     CameraPosition.Builder builder = CameraPosition.InvokeBuilder(); 
     builder.Target(latLng); 
     builder.Zoom(5); 

     CameraPosition cameraPosition = builder.Build(); 
     CameraUpdate cUpdate = CameraUpdateFactory.NewCameraPosition(cameraPosition); 

     mapFrag = (MapFragment)FragmentManager.FindFragmentById(Resource.Id.map); 
     map = mapFrag.Map; 
     if (map != null) 
     { 
      map.MoveCamera(cUpdate); 
     } 
    } 

Ben API anahtarı ile bir şey fark ama burada ne eksik?

Answer 1

Google API konsolunuza sağlanan karma kodun doğru olduğundan emin olun, debug.keystore için bir tane ve üretim anahtar deposu için bir tane olmak üzere iki karma sağlayabilirsiniz.

karma değerinin doğru olup olmadığını kontrol etmek için uygulamanızı hata ayıklama/üretim anahtar deposu ile çalıştırın, bu snippet'in günlük çıktısını kontrol edin (Java'da ancak Xamarin'de benzer API'lar olduğunu düşünüyorum) ve bunu karşılaştırmak için API konsolu: Burada

PackageInfo info; 
try { 
    info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES); 
    for (Signature signature : info.signatures) { 
     MessageDigest md; 
     md = MessageDigest.getInstance("SHA"); 
     md.update(signature.toByteArray()); 
     String something = new String(Base64.encode(md.digest(), 0)); 
     //String something = new String(Base64.encodeBytes(md.digest())); 
     Log.e("hash key", something); 
    } 
} catch (NameNotFoundException e1) { 
    Log.e("name not found", e1.toString()); 
} catch (NoSuchAlgorithmException e) { 
    Log.e("no such an algorithm", e.toString()); 
} catch (Exception e) { 
    Log.e("exception", e.toString()); 
} 

Answer 2

eklemek deneyin aşağıdaki uyarıyı vermeye başladı: AndroidManifest.xml'deiçinde <application> İçinde

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

Answer 3

C# uygulama

private void CheckSignatureHash() 
    { 
    try 
    { 
       PackageInfo info = PackageManager.GetPackageInfo("com.package.name", PackageInfoFlags.Signatures); 
       string hash = ""; 
       foreach (var sign in info.Signatures) 
       { 
        MessageDigest md = MessageDigest.GetInstance("SHA"); 
        md.Update(sign.ToByteArray()); 
        hash += Base64.EncodeToString(md.Digest(), Base64Flags.Default); 
        Console.WriteLine("***********************************"); 
        Console.WriteLine("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"); 
        Console.WriteLine("KeyHash:" + hash); 
        Console.WriteLine("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"); 
        Console.WriteLine("***********************************"); 
       } 

       //Toast.MakeText(this, hash, ToastLength.Short).Show(); 
    } 
    catch (PackageManager.NameNotFoundException e) 
    { 
    } 
    catch (NoSuchAlgorithmException e) 
    { 
    } 
}
