Android to get full path using Uri

String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(uri, filePathColumn, null, null, null);
cursor.moveToFirst();
 int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
 String picturePath = cursor.getString(columnIndex);

public String getRealPathFromURI(Uri contentUri) 
{
     String[] proj = { MediaStore.Audio.Media.DATA };
     Cursor cursor = managedQuery(contentUri, proj, null, null, null);
     int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
     cursor.moveToFirst();
     return cursor.getString(column_index);
