Prepare to start making calls to the currently registered callbacks. This creates a copy of the callback list, which you can retrieve items from using RemoteCallbackList.GetBroadcastItem(int). Note that only one broadcast can be active at a time, so you must be sure to always call this from the same thread (usually by scheduling with Android.OS.Handler) or do your own synchronization. You must call RemoteCallbackList.FinishBroadcast when done.
A typical loop delivering a broadcast looks like this:
java Example
int i = callbacks.beginBroadcast();
while (i > 0) {
i--;
try {
callbacks.getBroadcastItem(i).somethingHappened();
} catch (RemoteException e) {
// The RemoteCallbackList will take care of removing
// the dead object for us.
}
}
callbacks.finishBroadcast();
