Hi Megha!
I'm having a similar problem. I want to be able to create a
notification and schedule an alarm from a BroadcastReceiver class. Do
I have to make my BroadcastReceiver an inner class of an
Activity or is it just using a regular class that extends
BroadcastReceiver? Is it possible to launch other intents from a
BroadcastReceiver to trigger logic in an activity?
