            }
        Address obj = addresses.get(0);

        add = obj.getAddressLine(0) + "" + obj.getAddressLine(1) + ""

      } catch (IOException ioException) {
            //捕获IO流异常
            Log.e(TAG, "service_not_available" + ioException);
       } catch (IllegalArgumentException illegalArgumentException) {
            // 捕获纬度或经度值无效。
        Log.e(TAG, "Latitude = " + lat + ", Longitude = " + lng,
                illegalArgumentException);
