TLDR: Stream music from one Android to another Android device via bluetooth, remote controlling VLC or foobar2k or another app on source Android, displaying play/pause/nex/prev button and track name, which app (besides that one that came with my car Android radio)?
I got an old NoName China Android Car Radio (Android7 from 2017). This device comes with an app just called A2DP (and just called "Bluetooth' v2.4.0) in the App list), that magically is able to control VLC music from my Android smartphone. It's just got a Play/Pause, Next and Prev button, and is also showing the current track name from VLC.
I recently wrote myself a car dashboard app that displays the current track (via NotificationListenerService) which works with LOCAL VLC on my car Android, however not with this A2DP called China app open.
From what I think i found out is, that this app is probably not announcing/broadcasting the track name to the local car Android
(see e.g. send track informations via A2DP/AVRCP)
So to test out my theory I just wanted to try out ANOTHER app that does the same thing... and guess what... i searched the App Store, F-Droid and more, with search terms containing "bluettoh" "media controller" "avrcp/a2dp" "bluetooth music player" etc.etc... I COULDN'T FIND A SINGLE APP THAT DOES WHAT THIS CHINA APP DOES :)
So I'm questioning now if i'm missing something here... hope someone can point me in the right direction ;)
Thanks
Installed almost every app on Play Store that hast to do with bluetooth, nothing works. Even random .apk files....
