用于录制呼叫的媒体录制器有时无法录制对方语音

Question

在我的应用程序中，有一个录制语音呼叫的功能，它工作得很好。但在(三星s7、s8 )上测试时，效果并不好。该应用程序只能记录呼叫者的语音，而不能记录来自另一端的语音。以下是我的代码检查，请提出解决方案

MediaRecd = new MediaRecorder();
            MediaRecd.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL
            );

            MediaRecd.setAudioChannels(ConstantVariables.audioChannels);//monoRecording

   MediaRecd.setAudioEncodingBitRate(64);
            MediaRecd.setAudioSamplingRate(44100);


            MediaRecd.setOutputFormat(output_formats[pos]);//.mp3
            MediaRecd.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);//I already try with all possible CAMCORDER , MIC , Default etc etc but none was working
            MediaRecd.setOutputFile(Currentfilename);

            try {
                MediaRecd.prepare();
                MediaRecd.start();


            } catch (Exception e) {
                MediaRecd.reset();
                MediaRecd.release();
                MediaRecd = null;

            }

请帮帮忙

AudioSource.VOICE_CALL在一些安卓设备上不起作用，所以用下面的代码代替VOICE_CALL

先试试MediaRecorder.AudioSource.CAMCORDER

 MediaRecd = new MediaRecorder();
        MediaRecd.setAudioSource(MediaRecorder.AudioSource.CAMCORDER
        );

如果上述方法不起作用，则使用MediaRecorder.AudioSource.MIC

MediaRecd = new MediaRecorder();
        MediaRecd.setAudioSource(MediaRecorder.AudioSource.MIC
        );
