If you can get your agent of choice to run up the app in an emulator and navigate the whole thing taking screenshots then tasks like edge-to-edge can be pretty hands off.
The way I did it was to firstly get accessibility identifiers on everything. Then have it record everything I do on an emulator to navigate the entire app. Then left it for a while to work out how to actually use the app via the emulator. Once you have this sort of baseline. A lot of changes are really quite pleasant. I often ask for an HTML gallery of screenshots covering a few device sizes as the step before I bother running it on a device myself.
We use Roborazzi[0], which is an excellent screenshot library, but:
* We target minSdk 24
* We're still using XML views
* We target a large variety of form factors
* We have a lot of screens, and these have a lot of configuration options.
I really wish it was "point an agent at it, and walk away", but many screens ended up being hours of iteration with Fable driving my phone/an emulator to produce an acceptable outcome.
Given that my Pixel 9 Pro has system screens which are still broken under edge to edge, it's not an easy change, and takes up time which could have been going towards feature development.
