Hi! I'm trying to query the Android's MediaStore.Images.Media to get
the images contained in the device. I get my cursor on the DB like
this:
Cursor cursor =
context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projections, selection, null, sortColumn);
and I get the indices of the columns this way:
int dataIdx = cursor.getColumnIndex(DATA);
...
int idIdx = cursor.getColumnIndex(MediaStore.Images.Media._ID);
unfortunately it seems that the column index idIdx is always -1, which
means the column doesn't exist. Am I doing something wrong? Is there
anyone else experiencing the same?
Thanks!
