Hey @devgianlu, amazing to see what you are achieving here!
Still, there seems to be an issue left with tremolo on the master branch. Once I see the player UI I can't actually play a track. I get this error:

I am testing on a Pixel 3aXL with Android 11. What do you think, should I open a new issue for that?

[devgianlu]

That's strange, it's complaining about a missing native method, but it's there.

Maybe @funtax knows more

[funtax]

This happens because the package of the decoder has changed. The native code is still targeting the old package/class Java_xyz_gianlu_librespot_player_codecs_tremolo_OggDecodingInputStream.

I will try to fix this later and provide a new compiled version.

[devgianlu]

Oh right, I renamed it because the terminology codec was wrong (and it has been for way too long) and this was the right time to change it.

Thank you for looking into it

[funtax]

@devgianlu Could you give me write-access to this repo? Then I don't have to open a PR for such minor changes.

[devgianlu]

@funtax Invited you

[funtax]

Perfect, thank you @devgianlu .
@mitschwimmer I have updated the native library but not tested it yet. Feel free to update and give it another try.

[mitschwimmer]

@funtax, @devgianlu just tried it. Works great 🕺
