change setAudioSource(MediaRecorder.AudioSource.VOICE_CALL) TO setAudioSource(MediaRecorder.AudioSource.MIC) . It will work on android 6.0 and above. Make sure all permission's are allowed. — Hemant Parmar, Jan 05 '18 at 07:37

The MediaRecorder.AudioSource.VOICE_CALL source requires CAPTURE_AUDIO_OUTPUT permission which will be granted just for system apps and NOT for 3rd-party applications.

Perfect! Then how 3rd party apps are successful in recording caller and callie voice? – CopsOnRoad Mar 09 '18 at 14:27

They use NDK and cpp codes for that. please check the url: https://github.com/ViktorDegtyarev/CallRecLib – Homayoon Ahmadi Mar 10 '18 at 20:04
