MediaRecorder Exeption, wo liegt der Grund?

computer_freak · 04.04.2011, 21:18

Hallo!

Ich versuche seit einigen Tagen verzweifelt den MediaRecorder zum laufen zu bringen. Habe schon umfangreich gegoogelt, aber keine passende Antwort gefunden.

Nun zum eigentlichen Problem:

Code:

Und Hier meine Klasse, in der das Problem verursacht wird:

Code:

package com.testApp;

import java.io.File;
import java.io.IOException;

import android.app.Activity;
import android.content.res.Configuration;
import android.media.MediaPlayer;
import android.media.MediaRecorder;
import android.media.MediaRecorder.OnInfoListener;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class Record extends Activity
{

	private boolean IsRecording = false;
	
	private MediaRecorder recorder;
	
	private String tempFilePath = Environment.getExternalStorageDirectory().getAbsolutePath()+ "/Android/data/testApp/" ;
	public void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.record);
		tempFilePath += String.valueOf(System.currentTimeMillis()) + ".3gp";

		Log.d(RECORD_LOG, "onCreate done");
		
		recorder = new MediaRecorder();
		//recorder.reset();
		recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
		recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); // THREE_GPP = .3gp, RAW_AMR 
		recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
		Log.d(RECORD_LOG, "onCreate|tempFilePath=" + tempFilePath);
		recorder.setOutputFile(tempFilePath);
		recorder.setMaxDuration(6000);
		recorder.setOnInfoListener(new OnInfoListener()
		{
			@Override
			public void onInfo(MediaRecorder mr, int what, int extra)
			{
				if(what == MediaRecorder.MEDIA_RECORDER_INFO_MAX_DURATION_REACHED)
				{
					Log.d(RECORD_LOG, "recorder.onInfo called");
				}
			}			
		});
		
		try
		{
			recorder.prepare();
		}
		catch (IllegalStateException e)
		{
			e.printStackTrace();
		}
		catch (IOException e)
		{
			e.printStackTrace();
		}
	}
	
	public void recClicked()
	{
		
		if(IsRecording)
		{
			Log.d(RECORD_LOG, "recClicked entered, IsRecording = true, so we stop that thing");
			recorder.stop();
			recorder.reset();
			recorder = null;
			
			btn_play.setEnabled(true);
		}
		else
		{
			Log.d(RECORD_LOG, "recClicked entered, IsRecording = false, so we start that thing");
			btn_record.setText(R.string.record_rec2);
						
			recorder.start();
		}

		IsRecording = !IsRecording;
		
	}

	
	
}

Ich hoffe, jemand kann mich hier etwas aufklären
