So.. just in case any else comes here like me.. We used to have a profiler in android studio
View> Tool Window > Profiler..

and it would show you all the activities as you move throughout the app.. In Meerkat, its a bit more hidden, but still there,

1. Run the app in the emulator

2. open profiler

3. select Find CPU Hotspots

4. click btn Start anyway

5. use ur app..

Then u will get the recording of the activities used.
