Attempt to configure androidTest to not keep activities and background/resume activities under test

Can we configure androidTest to not keep activities and background/resume?

Note, this may not be possible / technically feasible. A quick exploratory attempt to configure an emulator programmatically (via adb?) to not keep activities is a first step. Then a load of one activity and background / resume cycle of that activity is a second step to see if it is even possible.

Would be an interesting way to surface these sorts of errors that happen semi-frequently where assumptions are made about activity (and now fragment) lifecycle in the face of need to re-construct activity

We have an "all activity load" type test that was meant to check for layout inflation issues, maybe that could be extended to not just load+inflate but also background the app while don't-keep-activities was set then foreground it again
