AppCompat-v7:21 provides a very useful way of dealing with pressed/focused/activated states maintaining backwards compatibility downto API-7, but there's a small issue (big for some) with the default selectableItemBackground: It uses some PNGs and/or default values for API<21.

The main reason is that android drawable resource definitions (prior API 21) CANNOT use theme attributes at all, so there's no way of making something like:
<shape android:shape="rectangle">
        <solid android:color="?attr/colorControlHighlight" />
</shape>

For this, I've put this simple mockup on how to give your app better drawables that the appcompat defaults.
