Alpha animation for "fading in" an image?
<p>I have an image that I would like to slowly fade in; I've played around with the standard animation constructs, but it never seems to work.</p>

<p>(Code for the image:)</p>

<pre><code>@Override
    public void draw(Canvas c, Layer layer) {
        if ( layer == Layer.BACKGROUND ) {              

            Animation a = new AlphaAnimation(1.00f, 0.00f);
            a.setDuration(4000);

            instructions.startAnimation(a);

            location.left = (view.getWidth() - instructions.getMinimumWidth() ) /2;
            location.right = location.left + instructions.getMinimumWidth();
            location.top = view.getHeight() / 2;
            location.bottom = location.top + instructions.getMinimumHeight();
            instructions.setBounds(location);
            instructions.draw(c);
        }
        //explosions.draw(c, layer);
    }
};
</code></pre>

<p>... "startAnimation is undefined for the type BitmapDrawable," it says.</p>
