Most of the support was already there, so this is just a few small steps:
- notify.js gets a dismiss_and_hide() exported function that can send the "notify-" event to Gadgetbridge, if installed
- dismiss_and_hide() is called when the Bangle.js screen is touched, instead of just hide()
- Gadgetbridge's widget.js saves "notify"-type events to a variable
- Gadgetbridge's widget.js sends a DISMISS action back to the Android app on "notify-" events, using the saved event data
Note that this is a limited implementation. For example, only the most recent notfication is saved (when a new one comes in, the old one is overridden in the variable), so it will be dismissed on the phone. A more advanced implementation might make it possible to choose which notification to dismiss.
From my own testing, this does properly count as a "swipe-away" style dismiss event in Android, so apps that react to notifications being swiped away will be triggered as expected.
