Get Mail Sent Notification in onActivityResult "Android"

I am launching a mail activity by

//Sending mail

final int SENT_MAIL = 1;

startActivityForResult(Intent.createChooser(i, "Send mail"),SENT_MAIL);

and in

onActivityResult(int req, int res,Intent data)

i am trying to find the result of email sending, so as to confirm if my mail wa开发者_StackOverflow社区s sent or was discarded by the user. I am recieving null for Intent data

i.e data =null

parameter in onActivityResult(int req, int res, Intent data), res is always 0.

ie. res = 0;

Please let me know what can be done in this case?

Thanks in advance!

You need to contact the developers of everything that could possibly ever respond to your Intent (which you do not show above) and ask them if they support startActivityForResult() for such an Intent. Odds are, few do, and you will have difficult tracking down all possible Android email clients, anyway. If they do not support startActivityForResult(), while you can still call that method, you will not get meaningful results in onActivityResult().

Hence, what you want is impractical, IMHO.
