Looks like you don't have the right permissions to use the camera service. Try adding this to your manifest file:

EDIT: It works for me! I used the same code as you, I know that I've said it before but check your permissions:

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.screen.portrait" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

I'm wondering that you add proper permission. you have to add permission in menifest.

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />

When you using camera, if camera is connected with another app, then you can't use camera(it maybe cause Fail to connect camera service).

So, you have to make sure only your app use camera service.

I hope you fix your error

Bye!

According to your crash log

02-20 05:42:56.054: W/System.err(4991): java.lang.RuntimeException: Fail to connect to camera service
W/System.err(4991):     at android.hardware.Camera.native_setup(Native Method)
02-20 05:42:56.054: W/System.err(4991):     at android.hardware.Camera.<init>(Camera.java:344)
02-20 05:42:56.054: W/System.err(4991):     at android.hardware.Camera.open(Camera.java:321)
02-20 05:42:56.054: W/System.err(4991):     at fun.audios.maker.VideoRecorderActivity.startRecording(VideoRecorderActivity.java:144)

, the camera couldn't be opened successfully in MediaRecorder.

You can read the Android tutorial - capture video Code:

private boolean prepareVideoRecorder(){

    mCamera = getCameraInstance();
    mMediaRecorder = new MediaRecorder();

    // Step 1: Unlock and set camera to MediaRecorder
    mCamera.unlock();
    mMediaRecorder.setCamera(mCamera);

    // Step 2: Set sources
    mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
    mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    // Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
    mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));

    // Step 4: Set output file
    mMediaRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).toString());

    // Step 5: Set the preview output
    mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());

    // Step 6: Prepare configured MediaRecorder
    try {
        mMediaRecorder.prepare();
    } catch (IllegalStateException e) {
        Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage());
        releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage());
        releaseMediaRecorder();
        return false;
    }
    return true;
}

If the code can't work, it should be your ROM issue.

I dont want facing-front camera! and also I now try you told. same exception gives me!! — sarah, Feb 20 '14 at 03:46
I've edited my answer. You can refer to Google's tutorial to have a try — yushulx, Feb 20 '14 at 05:51
what do i do with my ROM @yushulx ? cuz code dosnt worked. I write my code exactly according your code. — sarah, Feb 20 '14 at 07:28
Upgrade your system version, or flash other ROMs, such as CyanogenMod. Sometimes, the standard Android APIs can't work well on some devices. The compatibility is really a big problem of Android. I ever tried my own program on different smartphones with different ROMs, they performed differently. — yushulx, Feb 20 '14 at 08:34

Finally i found solution. I remove a part of my code and then start faild error didnt happen. i change code to this :

private void startRecording()  
    {
         mrec = new MediaRecorder(); 
         mCamera.unlock();

         mrec.setCamera(mCamera); 

         mrec.setAudioSource(MediaRecorder.AudioSource.MIC);
         mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);

         mrec.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

         mrec.setVideoFrameRate(15);
         mrec.setVideoSize(720, 480);

         mrec.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
         mrec.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);

         mrec.setPreviewDisplay(surfaceHolder.getSurface());   
         mrec.setOrientationHint(90); 

         mrec.setOutputFile(Videopath);

         try 
         {
             mrec.prepare();
             mrec.start(); 
         } 
         catch (IllegalStateException e) 
         {
           //  releaseRecorder();
          //   return false;
         } 
         catch (IOException e) 
         {
          //   releaseRecorder();
           //  return false;
         }
         catch (RuntimeException e) 
         {
            e.printStackTrace();
         }
         catch(Exception e)
         {
          //  return false;
         }

     }

i guess parameters values for invoke method has issue while setting.If you have some better resplonse revolving making better quality like my invoke method post your responses for help to me and other people read this post.
