Keep getting the error whenever I press the button. This does not make sense to me. Please ignore the class name as I wrote that out of frustration of this not working. android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. This is the error which keeps appearing.
