Answer 1

Yes it is possible for that use SurfaceHolder.Callback Interface . And

        @TargetApi(9)
    public void surfaceCreated(SurfaceHolder holder){
        Log.e(TAG, "surfaceCreated");
        mCamera = Camera.open(CaptureCameraImage.cameraID);
    }

    public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
        Log.e(TAG, "surfaceChanged");

        if (mPreviewRunning){
            mCamera.stopPreview();
        }

        try{
            mCamera.setPreviewDisplay(holder);
        }catch (Exception e){
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        mCamera.startPreview();
        mPreviewRunning = true;
        mCamera.takePicture(null, mPictureCallback, mPictureCallback);
    }

    public void surfaceDestroyed(SurfaceHolder holder) {
        Log.e(TAG, "surfaceDestroyed");
        //mCamera.stopPreview();
        //mPreviewRunning = false;
        //mCamera.release();
    }

For that use dummy surfaceview so you can take picture from background.

like

 SurfaceView dummy=new SurfaceView(context);
  dummy.addCallback(this);

And do some reasearch work on this dummy Surfaceview.
