Steps: 1. Go into Activity A-> Activity B -> Activity A by sending goback keycode 2. Call getLastActivity in ActivityMonitor class Result: The current activity is still Activity B. I think it's code defect. The relate code is following. If *mLastActivity*<http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.1_r1/android/app/Instrumentation.java#Instrumentation.ActivityMonitor.0mLastActivity> isn't null, it can't get updated even if it has been changed. It really blocks UI automation because getCurrentActivity is a common and necessary scenario in test cases. /**
