I am new to android family.I bought a galaxy trend mobile.I got it configured from one of my friend.I would like to know the gmail application automatically receives all the new mail and shows it as notifications.I want to know is it possible to password protect the application as it is risky because if for any reason my cellphone is lost the thief may gain access to the confidential mails as it is easy even to break the phone password as my friend got it done easily by approaching mobile shop.Please tell me the solution
