So, I finally updated my Android player (Android 8+). I´m using libopenmpt for playing the library's supported formats. I first wrote the routines for mod and xm myself, but that was too much work for such a hobby project, so I decided to use this great library!
The player is not finished yet, subsongs are not selectable, a playlist is missing and there is no configuration page yet.
There are also a few minor issues such as scrolling back from the tracker view when a module has more than 4 tracks. This is a nested scrolling problem, but I still don't know if the problem is on my side or on Google´s.
You can mute the channels in oscilloscope view oder tracker view and solo them with long press. Long pressing forward/previous buttons for song position jump selects the next/previous song.
I also wanted to add support for the AHX format at some point, as the sound of these files reminds me a lot of the good old Amiga :-)
You can find the player here:
