Make sure the browser works with Gmail. Browsers such as Chrome, Firefox, and Safari work well with Gmail, but some browsers don't. If you have problems and you know the browser is compatible, enable cookies and JavaScript. Use another browser or device.

Tap the Gmail app icon on your home screen or in the App Drawer. Tap Sign in. It's at the bottom of the screen. If you aren't currently logged into your preferred Google Account on your Android, you can instead tap Add another email address, tap Google, and enter your email address and password when prompted.

On your computer, go to Gmail. Enter your Google Account email or phone number and password. If information is already filled in and you have to sign in to a different account, click Use another account. If you get a page that describes Gmail instead of the sign-in page, at the top right of the page, click Sign in.
