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.

To find all your Gmail accounts or Google accounts, you can follow these steps: Open a web browser and go to the Google Account Recovery page (https://accounts.google.com/signin/recovery). On the account recovery page, enter the email address or phone number associated with your Google accounts and click "Next."
