Capture video without preview using Media Recorder

Question

I'm trying capture video (on lollipop) using Media Recorder, as I understand this class support capture without preview (link, #7 in the note):

It is possible to use MediaRecorder without creating a camera preview first and skip the first few steps of this process. However, since users typically prefer to see a preview before starting a recording, that process is not discussed here.

So, I build app that start capture video automatically and stops by button clicking but I get exceptions any time, here is my code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    recorder.setVideoSize(640, 480);
    recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT); // Tried to put this line in comment 
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT); // Tried to put this line in comment 

    /*CamcorderProfile camcorderProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
    recorder.setProfile(camcorderProfile);*/

    recorder.setOutputFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyVideo.gpp");

    try {
        recorder.prepare();
    } catch (IOException e) {
        e.printStackTrace();
    }

    recorder.start();

    final Button btnStopCaptureVideo = (Button) findViewById(R.id.bu_StopCapture);
    btnStopCaptureVideo.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            recorder.stop();
            recorder.reset();   // You can reuse the object by going back to setAudioSource() step
            recorder.release(); // Now the object cannot be reused
            Toast.makeText(MainActivity.this, "Video create successfully", Toast.LENGTH_SHORT).show();
            btnStopCaptureVideo.setEnabled(false);
        }
    });
}

When the code is like below I got RuntimeException (on recorder.start() line) and one I comment VideoEncoder and AudioEncoder and un-comment CamcorderProfile I got IllegalStateException exception (on recorder.setProfile(camcorderProfile) line).

So, the question is how can I capture Video without preview?
