For recording Android android.media.MediaRecorder can be used. All API are listed in this page http://developer.android.com/reference/android/media/MediaRecorder.html. This should solve all your issues. Sample code

 MediaRecorder recorder = new MediaRecorder();
 recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
 recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
 recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
 recorder.setOutputFile(PATH_NAME);
 recorder.prepare();
 recorder.start();   // Recording is now started
 ...
 while(recordingNotOver)
 {
    int lastMaxAmplitude = recorder.getMaxAmplitude();
    // you have the value here in lastMaxAmplitude, do what u want to
 }

 recorder.stop();
 recorder.reset();   // You can reuse the object by going back to setAudioSource() step
 recorder.release(); // Now the object cannot be reused
