The following videos show a variety of example add-on
applications. Each video generally walks through a short sample app to give you
a jump start in trying specific platform features.
Expedite expense reports with Gmail add-ons
Add-ons let you extend Gmail as well as integrate
functionality from your app into Gmail's user interface. In
this video, learn about the ExpenseIt! Gmail
add-on,
helping working professionals process receipts directly from their inbox into a
Sheet, creating one place to complete their expense reports. Build the
add-on piece-by-piece with its corresponding
codelab.
(Running time: 5:18)
This feature is also described in the blog post
"Gmail add-ons framework now available to all
developers".
Make progress (bars) with Slides add-ons
Google Slides doesn't have progress bars. Wouldn't this be a useful feature
for both presenters as well as audiences? In this video, developers learn how to
implement simple progress bars by using the Slides
service to create an
add-on.
With this add-on, users can enable
or hide progress bars in their presentations. The code and a full description
of this add-on can be found in the documentation as a
Quickstart example.
