With python3's htag (< v0.90.0) module.
Android's Apk built thru the htagapk recipe
To build : you can use the Build github's action or make.py
This is a (working) POC, just to see if the whole idea is OK.
history: I've got an android auto radio, with a 1280x480 (6.86") ... I don't like the current music player. So i try to replace it with something of my own. It's just to try if an android apk, using htag, can replace the current app.
You can test the APK on appetize (but there are no mp3 in the appetize vm, so you can't go further)
Basically, it's a "folder browser" which let you play mp3s. It will automatically create a playlist of random ones (those in the same or children/descending folders). You can play/pause by clicking on the cover (issued from mp3 tag), or increase/decrease volume.
And when it restarts, it will continue where it ended. (the 3 square/cross buttons are other paths on the device (usb/mass storage), to try ;-)).
