After query returns the cursor, it has to be moved forward. It can be done
as follows:
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(photoUri, new String[] {
MediaStore.Images.
>
> ImageColumns.LATITUDE,
> MediaStore.Images.ImageColumns.LONGITUDE
> }, null, null, null);
if (cursor != null && cursor.getCount() > 0) {
cursor.moveToFirst();
long fname = cursor.getLong(cursor.
>
> getColumnIndexOrThrow
> (MediaStore.Images.ImageColumns.LATITUDE));
>
> chatscreen.append("File Name: "+fname);
}
