Android相机错误100

Question

对于我的项目，我使用 MediaRecorder 来录制视频。

此代码适用于大多数设备，但在 HTC Desire（Android 2.3）中，当我调用 recorder.start(); 时，它会抛出 ERROR/Camera(25146): Error 100。有人知道如何解决它吗？

我的代码是这样的：

 Camera camera = Camera.open();

 Parameters parameters = camera.getParameters();

 if (flash) {
        parameters.setFlashMode(Parameters.FLASH_MODE_TORCH);
 }
 else {
    parameters.setFlashMode(Parameters.FLASH_MODE_OFF);
 }
 camera.setParameters(parameters);
 try {
    camera.setPreviewDisplay(holder);
 } catch (IOException e1) {
    e1.printStackTrace();
 }
 camera.startPreview();
 camera.unlock();

 recorder = new MediaRecorder();
 recorder.setCamera(camera);

 am = (AudioManager) context.getSystemService(Activity.AUDIO_SERVICE);
 am.setMode(AudioManager.STREAM_VOICE_CALL);
 am.startBluetoothSco();

 try {
        recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
        if(android.os.Build.VERSION.SDK_INT>=8){
            recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
            CamcorderProfile cp = CamcorderProfile.get(CamcorderProfile.QUALITY_LOW);
            recorder.setProfile(cp);
        }
        else{
            recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
            recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
            recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
            recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
                recorder.setVideoSize(CIF_WIDTH, CIF_HEIGHT);
                recorder.setVideoFrameRate(FRAME_RATE);
        }
        recorder.setMaxDuration(maxduration*1000);
        recorder.setPreviewDisplay(holder.getSurface());

    String data_folder=Environment.getExternalStorageDirectory().getAbsolutePath() + settings.location_in_sdcard;

            File ff=new File(data_folder);
        if(!ff.exists()){
            ff.mkdirs();
        }

            String path = data_folder+api.getCurrentTimeStamp()+".3gp";

        recorder.setOutputFile(path);

            try{
            recorder.prepare();
        }
            catch (Exception ee) {
            ee.printStackTrace();
        }
    }
catch (Exception e) {
    Log.e("ls", e.toString(), e);
} 

    recorder.start();
