Well, it works on my Android 14 device, but media notifications use media session for data since Android 13 and I didn't get around to trying an emulator. Might also be an problem caused by Huawei considering you're the first to report it but who knows.
On an Android 10 emulator, it works just fine. Can you maybe try the latest CI build from "Actions" tab?
Hi @tinkererkzy does this happen with all songs or only this specific one? Can you change song position in the app or does that not work either?
EDIT: I'm asking because some special MP3 files cannot be seeked in which would explain the observed behaviour (it will hide the seek handle)
to reverse the question, does it happen on all songs?
in addition, can you please send an interactive bug report created in developer options to [email protected] - thanks
Yes it does happen in all songs Also what title should I use on the email
I sent it! But while capturing the report the app crashed so i reopened it mid report
also here's a dumpsys media_session report (i had to put it in a file because of markdown)
thanks @tinkererkzy (while the bug report contains that as well, having one from yt music is nice for comparision)
I'm able to see that gramophone advertises the session as seekable so that's not the problem, the file can indeed be seeked in and that gets across to the system. I'm currently suspecting DefaultMediaNotificationProvider. please try this apk
Gramophone-1.0.16.1.ea1bf33-debug.apk.zip
Sorry but it's still broken :( (Also forgot to say the seekbar works,just the handle and the times are missing)

Hi @tinkererkzy does this APK work?
This is not Gramophone, it's Google's example app how to make a media notification. Gramophone works similarily to it, hence it'd be good to know if it works
@tinkererkzy thanks for testing, I'll get back to you in a few days~weeks with more stuff to test if you don't mind
@nift4 If you want to we can hop on a call and I let you control the device directly
I know it has been a very very long time, but are you still interested in getting this bug fixed?
Yeah ofc (But if you couldn't fix it i would be surprised(since Huawei kinda sucks in terms of android skins)
The app just plain crashed after installing on my P30 pro Mean while it worked fine on my A36(OneUI 8) Bug report:

Screenshots from A36:
Altough closing maybe beneficial to you since the only person using this edge case now unsupported device has migrated and thus not affected by the bug
So what do you think?
Eh, if you're still willing to test, I'd like to continue trying to fix it, because users being so patient and receptive to test builds is not that common.
