I am developing an Android App using Android Auto (not AAOS).
The application needs to have access to the audio streams natively produced by the car (e.g. the radio audio stream), therefore NOT generated by the connected phone. Is there a way to do so?
I suppose that turning on the radio in the car would bypass Android Auto and directly flow into the speakers, which would hinder my approach, however I cannot find any clear documentation that states so.
My only current alternative is to capture the radio stream using the microphone, but it is an obviously lossy workaround.
