How can we fix this error? java.lang.IllegalStateException

How should we go about fixing this code. We've spent the past 24 hours straight trying to get audio to save in Android

Our tired eyes would much appreciate the help!

We're trying to create an audio analysis app which analyses a microphone input

package com.example.opus2;

import android.content.ContentValues;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import java.io.IOException;



public class audioTest extends MainActivity{

    public int saveMarker=0;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.save_test);
    }


    public void onClick(View view){
        switch (view.getId()){

            case R.id.saveBttn: {

                Button saveButton= (Button) findViewById(R.id.saveBttn);
                if(saveMarker==0){
                    TextView done = (TextView) findViewById(R.id.done_text);
                    done.setText("Done2");
                    saveButton.setText("Saved?");
                    saveMarker=1;
                    String save_file = "viola";
                    try {
                        recordAudio(save_file);
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                    break;
                }
                else{
                    saveButton.setText("Save");
                    saveMarker=0;

                    break;
                }

            }
        }
    }

    public void recordAudio(String fileName) throws IOException {
        TextView done = (TextView) findViewById(R.id.done_text);
        done.setText("Done1");

        final MediaRecorder recorder = new MediaRecorder();
        ContentValues values = new ContentValues(3);
        values.put(MediaStore.MediaColumns.TITLE, fileName);
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
        recorder.setOutputFile("/sdcard/sound/" + fileName+".mp4");

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

        /* final ProgressDialog mProgressDialog = new ProgressDialog(audioTest.this);
        mProgressDialog.setTitle(R.string.lbl_recording);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        mProgressDialog.setButton("Stop recording", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                mProgressDialog.dismiss();
                recorder.stop();
                recorder.release();
            }
        });

        mProgressDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
            public void onCancel(DialogInterface p1) {
                recorder.stop();
                recorder.release();
            }
        });
        mProgressDialog.show();
        */

        recorder.start();
        done = (TextView) findViewById(R.id.done_text);
        done.setText("Done");
        }
}

Try to check the state of your Media Recorder if it actually is prepared. If not: wait for some milliseconds until it is prepared before calling the start record.

Also check the reference on android developers for more information on the different recorder states: http://developer.android.com/reference/android/media/MediaRecorder.html
