Android. How to record the microphone over audio stream?

问题

In my application playing music, the user should say at this time into the microphone. Can you please tell me how to make a record? Music and top path from the microphone. I looked through MediaRecorder, but there is not, in my opinion, an appropriate recording source.

For Recording Through Mic

Start and stop recording through Mic....

Start Recording

static MediaRecorder recorder = new MediaRecorder(); 
static String path, filename, time;
static int duration;
     public void startRecording() { 
        try {  
            recorder = new MediaRecorder();  
            recorder.setAudioSource(MediaRecorder.AudioSource.MIC);  
            recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);    
            recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);  
            System.currentTimeMillis();
            filename = ListenCallState.number + "_" + time + ".amr";
            File f = new File(getBaseURL());
            f.mkdirs();

            path = getBaseURL() + filename;
            recorder.setOutputFile(path);
            recorder.prepare();
            recorder.start();

        } catch (Exception {
        }
    }

Stop Recording

public static void stopRecording() {
        recorder.stop();
        recorder.release();
        try {
            MediaPlayer p = new MediaPlayer();
            p.setDataSource(path);
            p.prepare();
            duration = p.getDuration();
        } catch (Exception e) {
        }
 }
