Is it possible to place an android animation on top of the phonegap web view?

I'm new to phonegap / java. Because CSS Animation/Javascript animation is slow in Android, I am trying to create a Phonegap plugin that will place a native android animation on 'top' of the webview Phonegap uses.

Example: A clock background in the asset HTML, and a 'handRotation' plugin that will put an a native android animation of rotating hands on top of the webview.

If this is not clear let me know. I will continue trying to see if this is possible, and post my findings here, but any assistance is appreciated!

***UPDATE

I figured it out.

So given you have gotten through the Phonegap Plugin tutorial and you're sitting at your class that extends Plugin, here is what I did:

public PluginResult execute(String arg0, JSONArray arg1, String arg2) {
    // TODO Auto-generated method stub


    new Thread(new Runnable(){
        public void run(){
            final SampleView hands = new SampleView(webView.getContext());
            webView.post(new Runnable(){
                public void run(){
                    webView.addView(hands, new RelativeLayout.LayoutParams(
                            ViewGroup.LayoutParams.FILL_PARENT,
                            ViewGroup.LayoutParams.FILL_PARENT
                            ));
                }
            });
        }
    }).start();


    return new PluginResult(Status.OK,  webView.getId());
}

*The thread/runnable stuff is from the 2nd example in the Android UI Thread 开发者_Go百科Ref (any edits to the webView must be ran by the UI Thread)

** The magic door was knowing about the webView variable in the Plugin class, which refers back to the Phonegap webview. I found out about this only after peaking into the class.

***The SampleView is a view that contains a rotationAnimation. Here is the code for reference:

    public static class SampleView extends View {
    private AnimateDrawable mDrawable;

    public SampleView(Context context) {
        super(context);
        setFocusable(true);
        setFocusableInTouchMode(true);

        Drawable dr = context.getResources().getDrawable(R.drawable.handtrim);
        dr.setBounds(0, 0, dr.getIntrinsicWidth(), dr.getIntrinsicHeight());
        Log.v("test", "test");



        RotateAnimation an = new RotateAnimation(0f, 360f, 13f, 133f);

        an.setDuration(2000);
        an.setRepeatCount(-1);



        an.setInterpolator(getContext(), android.R.anim.linear_interpolator);
        an.initialize(10, 10, 10, 10);

        mDrawable = new AnimateDrawable(dr, an);
        an.startNow();
    }

    @Override protected void onDraw(Canvas canvas) {
        canvas.drawColor(Color.TRANSPARENT);
        int w = canvas.getWidth();
        int h = canvas.getHeight();
        int cx = w / 2;
        int cy = h / 2 - mDrawable.getIntrinsicHeight();

        canvas.translate(cx, cy);

        mDrawable.draw(canvas);
        invalidate();
    }
}
