This MP3 player has been tested on Android 11, 14 and 16.
It doesn't use extensions to access folders; it uses the tools available in Mit App Inventor 2 and a few tricks...;
Button functions:
-
SEL - select the folder containing the music you want to play. It must be located above Downloads, of course, due to security restrictions. Playback starts from the selected song until the end of the list;
-◄◄ AND ►► - play previous/next song; -
SI - enable textToSpeech for the currently playing title, which can be disabled;
-
|| - pause/play button
-
X - close the app;
-
file+ - add files to the selected list or create a new one;
-
file- - delete files from the list;
-
Save... to save the list permanently with a name of your choice;
-
Lists - access saved lists and select to play;
-
SH starts random playback (shuffle) of the selected list;
-
Del - deletes the saved list;
I added the joeDevMedia extension solely for managing the headphones (play, pause, next, prev) by enabling media session;
Since this is audio playback, it shouldn't stop when the screen is off, but it should still disable battery saving.
Have fun!
