illegalstateexception

I'm new to Robolectric and instrumentation testing in general on Android. I followed along the guide for Robolectric for testing my first test. However I'm getting: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity. I searched for the error, but no solution is helping.

I'm trying to figure out why occasionally I'm getting the IllegalStateException. I can't find any good examples that show how to load a list using a thread to query a SQLite database. I've included my code below. Most of the time it works correctly, but occasionally, I'm getting the IllegalStateException. I have also gotten a similar exception in another activity of mine that is an instance of ExpandableListActivity. That exception states "trying to requery an already closed cursor".

I'm experimenting with AudioTrack class. Basically, my app has to generate a sound when the user touches a specific object on screen. I've used this example as a guide. My app seems to work as it should but usually after touching the screen for about a minute it crashes: 07-02 20:40:53.459: E/AndroidRuntime(11973): FATAL EXCEPTION: Thread-10 07-02 20:40:53.459: E/AndroidRuntime(11973): java.lang.IllegalStateException: play() called on uninitialized AudioTrack. 07-02 20:40:53.459: E/AndroidRuntime(11973): at android.media.AudioTrack.play(AudioTrack.java:824) 07-02 20:40:53.459: E/AndroidRuntime
