Yes, the 1.1.1 version also works on my Dudu 7. I guess I had an older version. He started for Android 10 of course, where the old "SYSTEM_ALERT_WINDOW" functionality had to be used, but he now also implemented the new Android 12+ "ACTION_MANAGE_OVERLAY_PERMISSION". (I mention it here in case someone has a good tip for me 😉 )
However, I now copied Vasyl's functions from his display media titles, and do the same, but in my case the overlay still doesn't work (hence my question if FYT still had crippled the normal Android ROM, like they have done so often).
I now added PIP functionality to create a floating window (which can be dragged anywhere), just like Google Maps does (but much smaller as it only has to show current speed and overspeed), but somehow my overpass query doesn't work. When I "copy" my overpass query in a browser it works, but not from my app. My GPS part (lat, lon, current speed) works fine, but not the max-speed function.
It might take some more time to come to a working version (or maybe not at all)
