问题
According to Google in their Gmail Add-ons page
The contextual cards you create for your add-ons work for both web and mobile versions of Gmail. This means that you don't need to create separate web and mobile versions of the add-on—the same code works everywhere!
Note: Gmail add-ons have not yet been added to the iOS version of the Gmail app.
So the question here is really simple, I have a add-on that I'm testing on the browser, but how can I test it in the android Gmail app?
Thanks in advance.

Whatever account your using to build the add on, make sure you use that account on the gmail app on your phone. Open a message and scroll to the bottom and it will appear.
