I have an activity with a fragment, I have a cursorloader in the fragment, all my code seems to be fine but for some reason in my onLoadFinished event the view just shows a loading circle and none of the contacts from the phone are displayed – here’s my code

PS. There are alot of comments from android documentation as I am still learning so bear with me
