When I got my phone my gmail was working flawlessly. About a week or so ago my email was compromised somehow but wasn't affected since I have phone verification enabled. Anyway, I changed my password just to be on the safe side and as soon as I changed it, my gmail has stopped working. It would say that my password was incorrect which I did happen to change in the settings. I deleted the whole gmail account and set it up from scratch again but all it will do now is try to Synchronize. After some time, in the email and accounts section it will say that there is some attention required for the account which asks me to enter my password again and try to re-synchronize. So I have no idea why it would be doing this..
