what is the difference between sendStickyBroadcast and sendBroadcast in Android

by

Here is what the Android SDK says about sendStickyBroadcast():

Perform a sendBroadcast(Intent) that
is “sticky,” meaning the Intent you
are sending stays around after the
broadcast is complete, so that others
can quickly retrieve that data through
the return value of
registerReceiver(BroadcastReceiver,
IntentFilter). In all other ways, this
behaves the same as
sendBroadcast(Intent).

One example of a sticky broadcast sent via the operating system is ACTION_BATTERY_CHANGED. When you call registerReceiver() for that action — even with a null BroadcastReceiver — you get the Intent that was last broadcast for that action. Hence, you can use this to find the state of the battery without necessarily registering for all future state changes in the battery.
