ANDROID - Measuring the level of sound a user made and displaying it

I am currently writing an app that shows how loud the user is. I currently have it recording the sound when they press record using MediaRecorder and then allowing them to listen to that recording again by pressing play, this uses MediaPlayer.

I now want to some how output how loud the noise was that they recorded. Due to using the MediaRecorder I am trying to retrieve the loudness through.getMaxAplitude(). Using this I am then trying to display it in a textview so the user can see their results.

Therefore in doing this I have the current code in the begin recording function is 

 recorder = new MediaRecorder();
 recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
 recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
 recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
 recorder.setOutputFile(OUTPUT_FILE);
 recorder.prepare();
 recorder.start();

 int test = recorder.getMaxAmplitude();
 txtView.setText(test);

As you would have already guessed this doesn't work, the recording the audio does work but acquiring or showing the amplitude to the user isn't

Any ideas?

Probably you can take a view on the stackoverflow post here.

Also a similar kind of project is available in code.google.com
