App crashes on orientation change after I change my listview in same activity

My app starts in the MainActivity and uses a loader and custom adapter to populate my listview with the users' favourites. The data will persist over the orientation change.

But then if the user performs a search the listview in the MainActivity is repopulated with the new data. That works fine. But now, an orientation change crashes my app.

I'm also confused whether I have to explicitly save my instance before an orientation change or if Android does it for me. And if I have to do it explicitly would it be better to just perform the database query again instead?
