title: Can Instrumentation.ActivityMonitor look for any activity being started?
body: <p>According to the Android documentation, Instrumentation.ActivityMonitor is able to return an Activity that is being started. That is, you pass it an IntentFilter in its constructor so it knows what it's looking for. My question is, is it possible for ActivityMontior to look for any kind of Activity starting? In other words, is it possible to use ActivityMonitor to return the top most Activity showing on the foreground?</p>
