remember IntentReceivers have no GUI
and IntentReceiver != Activity
Don't know what you are exactly trying to do, but you could define your own Intent:
Using java Syntax Highlighting
protected static final String MY_INTENT_BLA_BLA = new String("android.intent.action.MY_INTENT_BLA_BLA");
Parsed in 0.011 seconds, using GeSHi
You'll should then to make your IntentReceiver listen to that Intent (in AndroidManifest.xml).
