     * Return the raw data associated with a particular resource ID.
     *
     * @param id The desired resource identifier, as generated by the aapt
     *           tool. This integer encodes the package, type, and resource
     *           entry. The value 0 is an invalid identifier.
     * @param outValue Object in which to place the resource data.
     * @param resolveRefs If true, a resource that is a reference to another
     *                    resource will be followed so that you receive the
     *                    actual final resource data. If false, the TypedValue
     *                    will be filled in with the reference itself.
     *
     * @throws NotFoundException Throws NotFoundException if the given ID does not exist.
