For Android developers:
It is slightly annoying when you develop that your Android phone goes to sleep. Or alternatively that when you charge it the screen stays on because of a development settings.
This app will keep your screen on during develop by listening to ADB notifications. It starts keeping your phone awake when a ADB "USB debugging connected" notification appears. It will allow your phone sleep again when the notification disappears.
Release to the store: I helps my development, hopefully it can help yours too.
