Question

我在Stackoverflow和其他论坛上遇到的问题discussed很多，但我有点奇怪。

我在Android上开发了一个谷歌地图v2，昨天工作正常，今天早上我打开地图的应用程序时没有显示地图。我卸载了应用程序并重新生成了地图api的密钥。现在它显示地图但不将地理坐标（纬度，经度）转换为字符串地址并出现异常：

这是我出现异常的代码片段。

private String getCompleteAddress(Context context,LatLng latLng) {

            Geocoder geocoder = new Geocoder(context);
            double latitude = latLng.latitude;
            double longitude= latLng.longitude; 

            try {
                List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 3);
                String address = addresses.get(0).getAddressLine(0);
                String city = addresses.get(0).getAddressLine(1);
                String country = addresses.get(0).getAddressLine(2);

                String completeAddress = "";

                if(address != null)
                    completeAddress = completeAddress +address+", ";
                if(city != null)
                    completeAddress = completeAddress +city+", ";
                if(country != null)
                    completeAddress = completeAddress +country;
                return completeAddress;

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return "";
        }

注意：该应用程序昨天工作正常，我用于测试的设备是三星Tab 3 10.1 Android v = 4.2.2
