     * would not correctly retrieve the final configuration density when
     * the resource ID passed here is an alias to another Drawable resource.
     * This means that if the density configuration of the alias resource
     * is different than the actual resource, the density of the returned
     * Drawable would be incorrect, resulting in bad scaling.  To work
     * around this, you can instead retrieve the Drawable through
     * {@link TypedArray#getDrawable TypedArray.getDrawable}.  Use

     * Context.obtainStyledAttributes} with
     * an array containing the resource ID of interest to create the TypedArray.</p>
