Android Call Recording Incoming voice not getting recorded

Question

I\'m working auto call recorder app, I\'m able to record voice call on below android 6 using MediaRecorder.AudioSource.VOICE_CALL, From android 6 not able to r

Answer 1

First these 3 permissions are needed in Manifest as well as a runtime permission request if the device is above Marshmallow,

2. MediaRecorder.AudioSource.VOICE_CALL is not supported on all phones so you need to continue using MediaRecorder.AudioSource.MIC.

I use this and works fine on most of the devices,

      recorder = new MediaRecorder();
      recorder.setAudioSource(audioSource);
      recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
      recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
      recorder.setOutputFile(your_path);

3. You need to set this to record your calls properly,

   audioManager.setMode(AudioManager.MODE_IN_CALL);

raise volume level when you start recording

audioManager.setStreamVolume(AudioManager.STREAM_VOICE_CALL,audioManager.getStreamMaxVolume(AudioManager.STREAM_VOICE_CALL), 0);

When you stop recording set the mode to normal, audioManager.setMode(AudioManager.MODE_NORMAL); and also set the stream volume to back how it was.
