Add possibility to select audio data source from external audio card

I have external audio card, Nexus 7 can work with external audio card, but in SDK I have no see any for this.

mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);

but need something like this:
mRecorder.setAudioSource(MediaRecorder.AudioSource.EXTERNAL_CARD_MIC);

also need advanced audio API for using - Line IN from external audio card.

I wanted to create open source universal oscilloscope(with input data source plugins system) for android (also with a possibility to get data from 1.5 USD USB audio card), but I can't to do this easy.

this app can work with external audio card https://play.google.com/store/apps/details?id=de.sobe.usbaudio

but I think need SDK support.

Like you said, this is an SDK issue. We can't do anything about this here because Patchfield builds on top of the existing SDK. I'll close this issue now.
