How can I get Activity from BroadcastReceiver ?

Generally, you can't. A BroadcastReceiver is independent from an Activity. For example, you can have BroadcastReceiver which receive broadcasts when no Activity is running.

You can, however, register/unregister a BroadcastReceiver in an Activity and use it to receive broadcasts while your Activity is running.
