How to get the email of current logged in user from twitter in android -

i'm integrating twitter application using twitter 4j library. i'm trying extract email of logged in user. there way can take email address of user without having prompt them?

i've checked here, doesn't quite explain how achieve i'm after.

you can't email user easily, if check documentation need whitelisted twitter. if aren't, can't email, twitter4j doesn't provide method achieve that.
