CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch views

Look like you are on the wrong thread. Try using a Handler to update the GUI on the right thread. See Handling Expensive Operations in the UI Thread example from android.com. Basically you would wrap byeSetup in a Runnable and invoke it with a Handler instance.

Handler refresh = new Handler(Looper.getMainLooper());
refresh.post(new Runnable() {
    public void run()
    {
        byeSetup();
    }
});
