I want to know how to get an array of pixels from the preview webcam (which I will run in a service). I've heard that the preview has to be displayed on a surface, but there will be no surface if I use a service.

I am very new to Android development, sorry for any misconceptions.

Thanks.

  • is it an external WebCam (USB or WiFi or BT), or the internal camera *used as* a WebCam? – Alex Cohn Jun 28 '14 at 09:34

  Parameters parameters = camera.getParameters();
       Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();

       if(display.getRotation() == Surface.ROTATION_0)
       {
           parameters.setPreviewSize(640, 480);                           
           camera.setDisplayOrientation(90);
       }
      camera.setParameters(parameters);


      camera.setPreviewDisplay(cameraSurfaceHolder);
      camera.startPreview();
      previewing = true;
