 * Denotes that the annotated element should only be called on the given API level
 * or higher.
 * <p>
 * This is similar in purpose to the older {@code @TargetApi} annotation, but more
 * clearly expresses that this is a requirement on the caller, rather than being
 * used to "suppress" warnings within the method that exceed the {@code minSdkVersion}.
