Simple recording app, need help

Hi,

I am trying to create a really simple audio recording app.
I followed the guide here: http://www.brighthub.com/mobile/google- ... 40735.aspx for the audio recording elements.

My app uses start and stop buttons to begin and end a recording. When I press Start, the app dies with the
"Sorry!: The application AudioRec has stopped unexpectedly. Please try again." error message. I am not sure what I could be doing wrong. My code is below, if anyone can find what I am doing wrong please let me know.

import java.io.IOException;
 
import java.lang.Object;
 
import android.app.Activity;
 
import android.media.MediaRecorder;
 
import android.os.Bundle;
 
import android.view.View;
 
import android.widget.Button;
 
import android.widget.TextView;
 
public class AudioRec extends Activity 
 
{
 
        public String PATH_NAME = "/sdcard/Music/Records";
 
        MediaRecorder MRX = new MediaRecorder();
 
    /** Called when the activity is first created. */
 
    @Override
 
    public void onCreate(Bundle savedInstanceState) {
 
        super.onCreate(savedInstanceState);
 
        setContentView(R.layout.main);
 
        final Button button = (Button) findViewById(R.id.Button01);
 
        button.setOnClickListener(new View.OnClickListener() 
 
        {
 
            public void onClick(View v) 
 
            {
 
                MRX.setAudioSource(MediaRecorder.AudioSource.MIC);
 
                MRX.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
 
                MRX.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
 
                MRX.setOutputFile(PATH_NAME);
 
                try {
 
                                MRX.prepare();
 
                        } catch (IllegalStateException e) {
 
                                // TODO Auto-generated catch block
 
                                e.printStackTrace();
 
                        } catch (IOException e) {
 
                                // TODO Auto-generated catch block
 
                                e.printStackTrace();
 
                        }
 
                MRX.start();
 
            }
 
        });
 
        final Button button2 = (Button) findViewById(R.id.Button02);
 
        button2.setOnClickListener(new View.OnClickListener() 
 
        {
 
            public void onClick(View v) 
 
            {
 
                MRX.stop();
 
                MRX.release();
 
            }
 
        });
 
    }
 
}

Hope it helps.
