[messages][messagegui] - fix music info handling

[kidneyhex]

Closing this: The fix requires design choices, so I'll just log an issue and let someone else decide. :P

I'll hold off reviewing / testing until this is out of draft, but with it being a core app I'll tag @gfwilliams in the meanwhile

The current code is working, but I ran into an app where GadgetBridge isn't sending musicinfo even on play/pause (libro.fm), so the music entry/controls aren't showing up.

If we could just request the info/state, it would simplify things and reduce the need for writing to flash. (I think?)

I see someone else proposed this too (https://codeberg.org/Freeyourgadget/Gadgetbridge/issues/4886), and it wasn't outright rejected, so I might do that this weekend and see if it's accepted, then revise this to use it.

--- I don't have access to an apple device though, so that does complicate things a little.

Cool! For that last bit, you could ask in discussions, I think there's a few iPhone users about

I'm really not convinced about requesting state (it feels like a hack to work around a bug somewhere) - I've put some more of my thoughts on this on https://codeberg.org/Freeyourgadget/Gadgetbridge/issues/4886#issuecomment-8622057

edit:

This is kind of what I mean - we should fix this in Gadgetbridge (or maybe it's a libro.fm issue?), and then it'll help everyone using it (even those without a Bangle.js).
