Is there a way for an Activity to find out who (i.e. class name) has sent an Intent? I'm looking for a generic way for my Activity to respond to a received intent by sending one back to the sender, whoever that may be.

There may be another way, but the only solution I know of is having Activity A invoke Activity B via startActivityForResult(). Then Activity B can use getCallingActivity() to retrieve Activity A's identity.

A:
Generally you don't need to know this. If the calling activity uses startActivityForResult(Intent, int), the callee can use setResult(int, Intent) to specify an Intent to send back to the caller. The caller will receive this Intent in its onActivityResult(int, int, Intent) method.

The intent from `setResult` is only sent once the child Activity is closed. I would like to be able to arbitrarily send intents back to parent activity while child activity is operating.
