Feature description

I want to be able to forward Antennapod's audio through ADB using sndcpy

Suggested solution:

Solution should be pretty straightforward. You only need to add android:allowAudioPlaybackCapture="true" to Antennapod's manifest

Thanks!

@abhisht51 Thanks! Those errors you were getting in your PR #4373 are pretty strange. Maybe the build tools need to be upgraded. Looks like implementing this is harder than I thought.

ExoPlayer 2.11 release notes:

Add allowedCapturePolicy field to AudioAttributes to allow to configuration of the audio capture policy.

Looks like after merging #4381, this will be easy to fix (cc @TacoTheDank)
