I have had this problem in the past and I didn't think much of it as I was only just experimenting with the IDE. However, I have realized the error also shows up when I create a fresh new application, even when I have added no code of my own I still get this error, any help would be appreciated to fix this issue.
So far i have tried to run methods on the UI thread as well as an asynchronous thread, but still no luck.
error:
E/AbstractTracker: Can't create handler inside thread that has not called Looper.prepare()
D/AppTracker: App Event: stop
