Implemented AsyncQueryHandler, but UI still locks up

I'm trying to asynchronously query another apps ContentProvider, but it's not going too well so far. I am able to query the database and get a result, but only synchronously (even with an asynchronous implementation).

I have created the following implementation of AsyncQueryHandler:
gist.github.com/Healios/4024afa6f73eaafc8ced291fbbfa75c9#file-dbasyncqueryhandler-cs

I am using the AsyncQueryHandler in my service in the following way:
gist.github.com/Healios/4024afa6f73eaafc8ced291fbbfa75c9#file-xxdbservice-cs

I am using the service in my ViewModel in the following way:
gist.github.com/Healios/4024afa6f73eaafc8ced291fbbfa75c9#file-testpageviewmodel-cs

With the above, supposedly asynchronous implementation, the UI still locks up/freezes. What am I doing wrong?
I need to be able to do asynchronous CRUD operations.

Does anyone have any experience in this area? It's not like it's booming with documentation on this subject.
