Android Splash screen cannot load another activity

The following is the code for my Android splash screen activity.

When it attempts to load another activity, the application crashes on Android 4.0 and 4.1.

I have no idea what's causing this because when it crashes, it does not log any error.

Has anyone come across anything like this befere?
