Android GeocoderNominatim.getFromLocationName（）给了我一个异常

我在OSMBonuspackV5.1中使用OSMDroidV4.3

我将国家名称“玻利维亚”传递给getLocationFromName，但我在浏览器的行列表中得到了一个IOException，我得到了一个正确的JSON

您知道如何解决这个问题吗？

NetworkOnMainThreadException=>请参阅

您有3种解决方案：

使用异步任务

Android SDK为了让它对我来说简单，我选择了change StrictMode.ThreadPolicy！工作得很好！请参见此处的操作方法：

GeocoderNominatim coderNominatim = new GeocoderNominatim(context);
try {
    List<Address> geoResults = coderNominatim.getFromLocationName("Bolivia", 1);

    if (geoResults.size() == 0) { 
             Toast.makeText(context, "Country not found.", Toast.LENGTH_SHORT).show();
     } else {
            Address address = geoResults.get(0);
            Bundle extras = address.getExtras();
            BoundingBoxE6 bb = extras.getParcelable("boundingbox");
            mapView.zoomToBoundingBox(bb);
     }
} catch (IOException e) {
    Toast.makeText(context, "Geocoding error", Toast.LENGTH_SHORT).show();
}
