java - Android - 地理编码器未获取地址字符串

Question

在提供纬度和经度后，我有以下代码来获取完整的地址字符串。但它一直在给出异常(exception)。我不知道为什么这段代码没有返回地址。请帮忙。谢谢。

private String getCompleteAddressString(double LATITUDE, double LONGITUDE) {
        String strAdd = "";
        Geocoder geocoder = new Geocoder(this, 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.w("My Current loction address", "" + strReturnedAddress.toString());
            } else {
                Log.w("My Current loction address", "No Address returned!");
            }
        } catch (Exception e) {
            e.printStackTrace();
            Log.w("My Current loction address", "Canont get Address!");
        }
        return strAdd;
    }

地理编码器非常不稳定。当它进入您报告的状态时，重启设备通常会“修复”它。如果您想要一个可靠的解决方案，我建议您查看 Google Geocoding API。
