android相机故障代码解决方法,Android相机服务器死机和相机错误 – 100

我在测试我的Android应用程序时遇到Camera错误100,我在StackOverflow上找到了一些主题,但它们并没有那么有用.我正在寻找解决错误的相关解决方案.

我写的代码：

mrec = new MediaRecorder(); // Works well

mCamera = Camera.open();

mCamera.unlock();

mrec.setCamera(mCamera);

mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);

mrec.setAudioSource(MediaRecorder.AudioSource.MIC);

mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));

mrec.setOutputFile("/sdcard/zzzz.3gp");

mrec.prepare();

mrec.start();

记录相机的代码：

protected void startRecordingVideo() throws IOException

{

camera = Camera.open();

camera.unlock();

SimpleDateFormat timeStampFormat = new SimpleDateFormat(

"yyyy-MM-dd-HH.mm.ss");

String fileName = "video_" + timeStampFormat.format(new Date())

+ ".3gp";

String fileURL = "/sdcard/"+fileName;

surfaceView = (SurfaceView) findViewById(R.id.surface_camera);

surfaceHolder = surfaceView.getHolder();

surfaceHolder.addCallback(this);

surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

mrec = new MediaRecorder();

mrec.setCamera(camera);

mrec.setPreviewDisplay(surfaceHolder.getSurface());

mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);

mrec.setAudioSource(MediaRecorder.AudioSource.MIC);

mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_LOW));

mrec.setPreviewDisplay(surfaceHolder.getSurface());

mrec.setOutputFile("/sdcard/"+fileName);

mrec.prepare();

mrec.start();

}

protected void stopRecordingVideo() {

mrec.stop();

mrec.release();

camera.release();

}

private void releaseMediaRecorder(){

if (mrec != null) {

mrec.reset(); // clear recorder configuration

mrec.release(); // release the recorder object

mrec = null;

camera.lock();

}

}

private void releaseCamera(){

if (camera != null){

camera.release();

camera = null;

}

}

@Override

public void surfaceChanged(SurfaceHolder holder, int format, int width,

int height) {

// TODO Auto-generated method stub

}

@Override

public void surfaceCreated(SurfaceHolder holder) {

// TODO Auto-generated method stub

if (camera != null){

Parameters params = camera.getParameters();

camera.setParameters(params);

}

else {

Toast.makeText(getApplicationContext(), "Camera not available!", Toast.LENGTH_LONG).show();

finish();

}

}

@Override

public void surfaceDestroyed(SurfaceHolder holder) {

releaseMediaRecorder();

camera.stopPreview();

camera.release();

}

以下是Logcat输出：
