I know how to use the TelephonyManager to get a device id, country code (even telephone number I believe).
However, I would like to retrieve the "username" similar to when you post a note in the Android market.
It seems the market application is able to fill in your username (perhaps this is the first part of an email address, I don't know) automatically.
I'd like to be able to have users post notes in my application too, without also having to enter a username.
Does anybody know how to achieve this?
