Call Recorder issue in some devices , Call recorder not working on device 7.1.1 , not able to record other person voice

Question

I was developing a android app for recording calls using media recorder ,it was working fine for some devices but not recording voice of other person on devices which are on 7.1.1 and greater ,specially on moto g devices .

This is my media recorder code

recorder.setMaxDuration(60 * 60 * 1000);
                    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                    recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
                    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
                    recorder.setAudioEncodingBitRate(64 * 1024);
                    recorder.setAudioSamplingRate(44 * 1000 + 100);
                    recorder.setAudioChannels(MONO_CHANNEL);

Is there any way to achieve this .please suggest

Answer 1

I meet same problem when recording call. Solve by change audioSource to VOICE_COMMUNICATION

recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION);
