Android intents to launch music app on phone

Yeah, this grew a bit while working it out - scope creep is a real thing I guess 😛. But I've learnt a lot and it felt worthwhile to add as much functionality as possible when I already got going. Hopefully someone other than me will end up using it 😅.

I feel like this is pretty much done now. But if anyone has questions or suggestions for improving intents functionality going forward I'd be happy to at least give some input or potentially implement stuff myself.

(edit: One thing on my radar is handling of service-intents maybe will have to be done differently in the future, with workmanager instead. But I had a hard time wrapping my head around that..)

And thanks for your help on this as well!
