Android Question ContentResolver Query query (pardon my little pun)

I am using ContentResolver to query for images in the gallery, this being the documented Query call:

Query (Uri As Uri, Projection() As String, C, SelectionArgs() As String, SortOrder As String) As CursorWrapper

It seems that the selection clause (Selection As String) can only be a simple clause like:

"relative_path = ? AND mime_type = ?"

Which I have working, but I'd like to be able to do something like:

"relative_path CONTAINS ? AND mime_type = ?"

I have tried every permutation I can think of and googled myself silly without any luck.

Is this possible? If so can anyone give me some guidance as to the exact verbage.

agraham thanks for your interest.

You set me googling on SQL Where clause, this seemed simplest and most informative:

https://www.w3schools.com/sql/sql_where.asp

this implies I should be able to query on

"relative_path LIKE ? AND mime_type = ?"

but I couldn't get this to work either 😡😡😡
