* @deprecated Sticky broadcasts should not be used. They provide no security (anyone

* The recommended pattern is to use a non-sticky broadcast to report that <em>something</em>
* has changed, with another mechanism for apps to retrieve the current value whenever
* desired.
*
* @param intent The Intent to broadcast; all receivers matching this
* Intent will receive the broadcast, and the Intent will be held to
