Hi there! I recently started running ALAS on a cheap android tablet with a 1 minute display timeout to save energy. I also have it configured to close the game on tasks completion.
However, after ALAS goes to idle and closes the game, it would always fail with logs that look like this and a pure black screenshot:
This seems to be because the device went to sleep, so I added a new function to check for device interactivity (which is set to false when display is off), and used it in the ui_get_current_page and handle_app_login loops to wake the device if not interactive.
I've been running with these changes for the past week and it hasn't required any manual interventions yet. I've defaulted the result of the function to true in the case where we can't find the expected adb outputs to keep behavior identical for older devices and emulators, but I haven't actually tested on an emulator yet since I don't have one set up. Would appreciate some help with this from folks that run ALAS on emulators!
I'm a bit of a python noob, so there might be some mistakes in here. Happy to update this as you see fit. Thanks!
