Android Camera as a Service无法在所有设备上运行

Question

此单击图像作为服务的代码在某些方面非常有效：三星聊天，但不适用于：HTC One，Google Nexus。在调用takepicture时抛出RuntimeException。给我一些建议，我在这个实现中出错了。

public class cs extends Service implements SurfaceHolder.Callback{

     private SurfaceView sv;
     boolean previewing = false;
     private SurfaceHolder sHolder; 
     private Camera mCamera=null;
     private Parameters parameters;

    @SuppressLint("NewApi")
    public cs( Context cc) {

         mCamera = Camera.open(); //using default camera
         sv = new SurfaceView(cc);

        try {
              mCamera.startPreview();
              mCamera.takePicture(null, null, mCall);

         } catch (Exception e) {
               e.printStackTrace();
         }

        sHolder = sv.getHolder();
        sHolder.addCallback(this);
        sHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        mCamera.release();
        }

       Camera.PictureCallback mCall = new Camera.PictureCallback()
       {
          public void onPictureTaken(byte[] data, Camera camera)
          {

                    FileOutputStream outStream = null;
                     try{
                         outStream = new FileOutputStream("/sdcard/Image.jpg");
                         outStream.write(data);
                         outStream.close();
                     } catch (FileNotFoundException e){
                         Log.d("CAMERA", e.getMessage());
                     } catch (IOException e){
                         Log.d("CAMERA", e.getMessage());
                     }
               }
       };

     @Override
     public IBinder onBind(Intent intent) {
           // TODO Auto-generated method stub
           return null;
     }

     public void surfaceChanged(SurfaceHolder holder, int format, int width,int height) {
           if(previewing){
               System.out.println("stop previewing");
               mCamera.stopPreview();
               previewing = false;
           }

     }

     public void surfaceCreated(SurfaceHolder holder) {
           // TODO Auto-generated method stub

     }

     public void surfaceDestroyed(SurfaceHolder holder) {
           System.out.println("camera stop previewing");
           mCamera.stopPreview();
           mCamera.release();
           mCamera = null;
           previewing = false;   
     }

     }
