我是Android开发的新手,我正在开发一个Android应用程序,我将地址转换为纬度和经度。我正在使用地理编码器。但是,当我打电话给那个功能app力量关闭。 这是我的代码段
public void getLatLongFromGivenAddress(String address)
{
double lat= 0.0, lng= 0.0;
Geocoder geoCoder = new Geocoder(this, Locale.getDefault());
try
{
List<Address> addresses = geoCoder.getFromLocationName(address , 1);
if (addresses.size() > 0)
{
GeoPoint p = new GeoPoint(
(int) (addresses.get(0).getLatitude() * 1E6),
(int) (addresses.get(0).getLongitude() * 1E6));
lat=p.getLatitudeE6()/1E6;
lng=p.getLongitudeE6()/1E6;
String lati =String.valueOf(lat);
String longi =String.valueOf(lng);
Log.d("Latitude", ""+lat);
Toast.makeText(getApplicationContext(), lati, Toast.LENGTH_LONG).show();
Log.d("Longitude", ""+lng);
Toast.makeText(getApplicationContext(), longi, Toast.LENGTH_LONG).show();
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
这是我的logcat

我应该做些什么改变? 谢谢!
