How to get file path from Google Drive

[danmacleod]

I'm retrieving the path to an image from a Uri and saving the path in one of my domain objects for future use. This works fine for images stored on the local device by using a cursor (see below) . However, I'm not sure how to get the file path when the image is stored on my Google drive. The Uri below is an example. I've seen many posts about this issue but I haven't found a solution. Any ideas?

cursor = context.getContentResolver().query( uri, projection, selection, selectionArgs, null );
if ( cursor != null && cursor.getCount() >= 1 && cursor.moveToFirst() ) {
    final int index = cursor.getColumnIndexOrThrow( column );
    return cursor.getString( index );
}
