ANDROID：错误 W/DynamiteModule：com.google.android.gms.googlecertificates 的本地模块描述符类未找到

Question

我正在尝试使用 Android Studio 进行 MapActivity。它必须显示用户的位置。

好吧，我知道我需要一个密钥才能使用 API，相信我，我至少更改了四次密钥……我还拥有 AndroidManifest.xml 中的权限。

问题是我可以在没有用户位置的情况下显示地图，但是如果我尝试显示他/她的位置，那么应用程序编译良好但是当我尝试执行它时，它会停止并且我收到此错误：

11-12 09:13:28.416 21576-21653/raquel.mapapplication W/DynamiteModule: Local module descriptor class for com.google.android.gms.googlecertificates not found.

它提到了一些关于谷歌证书的东西，这就是为什么我认为它可能与密钥有关......但我不确定，我不知道我做错了什么。

感谢您的帮助。

////////

好的，我会尝试发布一些代码...我一直在更改代码，但这是我最后一次尝试（我也尝试过 setMyLocationEnable(true)，因为不推荐使用 getMyLocation()，但我得到同样的错误）：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        Location location=mMap.getMyLocation();

        double lat=location.getLatitude();
        double lon=location.getLongitude();

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(lat, lon);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
}

感谢回答我的人和编辑我评论的人...我仍然不知道如何格式化文本...

加载证书可能是 API 中的错误，我认为任何谷歌开发人员也曾在某处描述过，播放服务正在尝试登录以验证播放应用程序或第三方应用程序，因此这可能是错误的。我不知道更多。

但是如果您仍然无法在用户位置上放置标记，您可以尝试下面的代码，我已经对其进行了测试并且正在应用程序中工作

@Override
public void onMapReady(GoogleMap googleMap)

{
    myGoogleMap = googleMap;
    placeMarkerOnPosition();
}

public void placeMarkerOnPosition() {
//// check permissions to access resources ///////// 
if (ActivityCompat.checkSelfPermission(this, 
android.Manifest.permission.ACCESS_FINE_LOCATION) != 
PackageManager.PERMISSION_GRANTED && 
ActivityCompat.checkSelfPermission(this, 
android.Manifest.permission.ACCESS_COARSE_LOCATION) != 
PackageManager.PERMISSION_GRANTED) {

    return;
}
    LocationManager locationManager = (LocationManager) 
    getSystemService(Context.LOCATION_SERVICE);

现在你可以通过两种方式找到它

////////////////  find location if GPS provider is available (GPS should 
enable to envoke this callback)

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, 
new LocationListener() 
{
 @Override
 public void onLocationChanged(Location location) {

try {
    Geocoder geocoder = new Geocoder(getApplicationContext());                              
    myLatitude = location.getLatitude();
    myLongitude = location.getLongitude();
    LatLng myPosition = new LatLng(myLatitude,myLongitude);
    List<Address> places=geocoder.getFromLocation(myLatitude, 
    myLongitude,1);
    myLocation = places.get(0).getSubLocality() 
                 +""+places.get(0).getLocality();

    myGoogleMap.clear();
    myGoogleMap.addMarker(new 
    MarkerOptions().position(myPosition).title(myLocation));

    myGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myPosition, 
                                                                 13.5f));


    } catch (IOException e) {
      e.printStackTrace();
    }
   }

    @Override
    public void onStatusChanged(String s, int i, Bundle bundle) {

    }

    @Override
    public void onProviderEnabled(String s) {

    }

    @Override
    public void onProviderDisabled(String s) {

    }
    });

////////////////   checking with network providers   /////////


if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {


locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 
                                       0, new LocationListener() {
@Override
public void onLocationChanged(Location location) {
myLatitude = location.getLatitude();

LatLng myPosition = new LatLng(myLatitude, myLongitude);
myGoogleMap.clear();
myGoogleMap.addMarker(new MarkerOptions().position(myPosition).title("My 
                                                             Position"));

myGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myPosition, 
                                                              13.5f));

}

                @Override
                public void onStatusChanged(String s, int i, Bundle bundle) 
                {

                }

                @Override
                public void onProviderEnabled(String s) {

                }

                }

打开sdk manager，下载/更新google play services。 并创建一个新的模拟器。
