Add multiple Gmail accounts in Gmail app Is there a way to do this?

I currently have Android 4.1.2 on an S3, and while I can do this on the e-mail app, I much prefer to use the Gmail app for its interface.

I know that this was possible in earlier versions.

Is this still possible, and if so how?
There's nothing special you need to do within Gmail. (In fact, there's nothing you can do in Gmail.)

Simply add the Google account(s) to your device under Settings &gt; Accounts &gt; Add account. (It will then appear there listed under "Google Account".)

After that make sure you're syncing Gmail plus whatever other Google services you want (or not).
