Android在服务中使用地理编码器获取位置地址

我跟着 this 获取位置坐标和地址

所以这里每10秒更新一次位置坐标纬度和经度

我正试图找到他们的地址

这里是我使用的地址 Const 班

public class Const {

public static String getCompleteAddressString(Context m_context, double LATITUDE, double LONGITUDE) {
    String strAdd = "";
    Geocoder geocoder = new Geocoder(m_context, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
        if (addresses != null) {
            Address returnedAddress = addresses.get(0);
            StringBuilder strReturnedAddress = new StringBuilder("");

            for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
                strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
            }
            strAdd = strReturnedAddress.toString();
            Log.v("My Current location add", "" + strAdd.toString());
        }
    } catch (Exception e) {
        e.printStackTrace();
        Toast.makeText(m_context, "Sorry, Your location cannot be retrieved !" + e.getMessage(), Toast.LENGTH_SHORT).show();

    }
    return strAdd;
}
}

现在在 Main Activity 获取我使用的地址

private void updateUI() {
mLatitudeTextView.setText(String.format("%s: %f", mLatitudeLabel,
        mCurrentLocation.getLatitude()));
mLongitudeTextView.setText(String.format("%s: %f", mLongitudeLabel,
        mCurrentLocation.getLongitude()));
mLastUpdateTimeTextView.setText(String.format("%s: %s", mLastUpdateTimeLabel,
        mLastUpdateTime));

//For Address

mLocAddTextView.setText(String.format("%s: %s", mLocAddressLabel,
Const.getCompleteAddressString(this, mCurrentLocation.getLatitude(), mCurrentLocation.getLongitude())));
 }

但在这里它的显示没有人能告诉我这有什么错
