java.io.IOException：grpc失败了

当我使用call getFromLocationName时,我得到一个IOException,其描述为“grpc failed”.

运行的代码

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    try {
        Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
        List<Address> listAdresses = geocoder.getFromLocationName("London", 10);
        Log.i("PlaceInfo", listAdresses.get(0).toString());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

控制台输出错误：

Android SDK版本(API级别)：25

Android Studio插件是最新的.

提前致谢！

编辑：

现在问题似乎已解决,这是我的solution.

解决方法:

可能你只是在genymotion和android studio模拟器中遇到这个问题.我面临与genymotion和android工作室模拟器相同的问题,然后我在Android真实设备中检查它.这对我有用.你在真实的设备上检查过吗？
