Android Java：地理编码器 grpc 失败异常

如何解决Android Java：地理编码器 grpc 失败异常

我将带您了解关键点，请耐心等待。

我在做什么

我从位置管理器获取位置并使用地理编码器获取城市名称。

我是怎么做的 在位置更改功能中，我创建了一个新线程并创建了一个新地址列表，以便在 try catch 块中从地理编码器获取地址。

代码

public void onLocationChanged(Location location) {
    Log.d("onLocationChanged","Before if");
    if (location != null){
        Log.d("if location not null","start");
        Geocoder geocoder = new Geocoder(getContext(),Locale.getDefault());
        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    Log.d("TAG","onLocationChanged: Location : " +location);
                    List<Address> addresses = geocoder.getFromLocation(location.getLatitude(),location.getLongitude(),1);
                    Log.d("TAG","onLocationChanged address: "+addresses);
                    city = addresses.get(0).getLocality();
                    search(city);
                    return;
                } catch (IOException e) {
                    progressDialog.dismiss();
                    Log.d("IOException","at geocoder " + e.getMessage());
                    //Toast.makeText(getContext(),"Slow Connection...Try Later.",Toast.LENGTH_LONG).show();
                    e.printstacktrace();
                }
            }
        });
        thread.start();

    }
    else {
        progressBar.setVisibility(View.INVISIBLE);
        Log.d("Location is null","else");
        Toast.makeText(fl.getContext(),"Cannot Access Current Location...",Toast.LENGTH_LONG).show();
        return;
    }

}

发生了什么

根据日志，正在获取位置，但调用 geocoder.getFromLocation 函数时发生 grpc Failed 异常。

注意：这个函数在上个月运行得很好，没有抛出任何异常。

谢谢，感谢任何建议或反馈。
