How to know whether Send/Discard/Cancel button pressed in Email Compose Activity - Android

I have launched email compose Activity by using Intent.ACTION_SEND.

Can someone please tell me how I can g开发者_开发问答et the confirmation/callback when user Send, Discard or Cancel email?

You can't. There is no standardized intent returned by email apps in response to ACTION_SEND. The best way to do it would be to provide the form for creating the email yourself, and only send the intent off if the user chooses to actually send it.
