how to sync my university email to my Android?
This question is impossible to answer without knowing the configuration your university uses. You should ask for the details of the mail server from the university's helpdesk. You'll need to know at least the server address, username and password for your mail account, and possibly even more details such as custom port numbers, access restrictions, protocols to use, encryption etc.

I'm certain that the helpdesk can assist you in getting the email settings correctly into your phone.
