I reproduce the issue with the Auto emulator.
With dev branch it works fine, that's due to a more recent version of the SDK.
When you say dev branch, do you mean dev branch of VLC or of Android Auto? (I'm assuming dev branch of Android Auto, because I'm still having the issue with the latest VLC Nightly, but I just wanted to verify.)
I'll try to figure out what's the difference, but I'm not sur I can fix it for 3.0 :/
Once again, when you say "3.0", do you mean VLC 3.0 or Android Auto 3.0? (It's a little confusing since both are at version 3.0 right now.)
