Android Auto rejected because of audio not ducking

ExoPlayer Version

2.18.1

Devices that reproduce the issue

I have no idea which device google is using for testing Android Auto.

Here is my code.

player = ExoPlayer.Builder(context).build()
        player?.setHandleAudioBecomingNoisy(true)
        val audioAttributes: AudioAttributes = AudioAttributes.Builder()
            .setUsage(C.USAGE_MEDIA)
            .setContentType(C.AUDIO_CONTENT_TYPE_MUSIC)
            .setAllowedCapturePolicy(C.ALLOW_CAPTURE_BY_ALL)
            .build()
        player?.setAudioAttributes(audioAttributes,true)
        player?.addListener(this)

@wasmedia96 just to reassure you a little, it’s frustrating as hell, it makes everybody loose time but you get used to it, because you have no choice 😃

Same exact random rejection the 28th September, updated version code and it passed as with now nearly 30 times happened in the last 7 years of Android Auto support in that app.

Even if you appeal and they redo the tests they will ask you to republish a new APK so don’t waste time if you can’t reproduce what they say.

Good luck with your app.

Then there is probably not much we can do in this issue tracker because the player is doing the right thing. If you think the certification isn’t testing their requirements correctly, you probably need to get in touch with them to clarify that.
