title: How get Activity form BroadcastReceiver in onReceive
body: <p>I define BroadcastReceiver in an application manifest and the receiver receives events in onReceive as expected. However I do not create the receiver class so I can't pass any information about my activity which the receiver is supposed to control. Context parameter gives me only application context and no any activity reference. So what is right way to make communication between application activities and broadcast receiver?</p>
