Intents? How to register to be alerted for incoming emails?

Extreme Android developer newbie here...well, new to Android development, not development in general.

I want to write an application that gets notified when emails come into the device, and takes various actions based on data in the email (subject, sender, to, etc). I think what I have to do is create a BroadcastReceiver with an IntentFilter. The problem I'm having is figuring out what Intent(s) I need to "listen" for. Can anyone point me in the right direction?开发者_C百科 Thanks.

There are no broadcast Intents for incoming emails. Email is handled at the application level, and there are lots of possible email clients.

Sorry!
