I am trying to run my android app in the “Android Developer Tools Build: v21.0.0-519525” for mac osx. The emulator starts fine but just keeps looking like this:

Yesterday it worked just fine. I have tried to close ADT and run:
>adb kill-server
>adb start-server
as described here:
Android app not launching on emulator
are there any temporaries that needs to be deleted?
Take the emulator off the screenlock by swiping the lock from left to right first before starting the app.
