title: Apply an Animation on a Drawable in Android
body: <p>I am adding a glow animation effect to a logo. So far, I have managed to get the glow image behind the logo, using a LayeredDrawable, but I can't figure out how to animate it. I have found that AlphaAnimation would achieve the desired effect, but unfortunately I can only apply it on Views, not Drawables. How can I achieve this effect?</p>
