Gmail stopped syncing messages For some reason, Gmail on my Nexus S is not pulling new messages anymore. I added a second Gmail account; could it possibly be the reason?
The second account probably has nothing to do with the other. 

You'll want to go to Menu | Settings | Accounts &amp; sync and click on the account that's not working. Ensure that "Sync Gmail" is checked.

If that doesn't help, then you should try what I do for all truculent apps.


Force stop


if that doesn't help


Clear cache


if that doesn't help


Clear data


if that doesn't help


Restart the phone (turn off/turn on the phone, unless you have a "restart" option)


and if that still doesn't help, try the nuclear option:


uninstall and re-install
