We've already gathered up a bunch of screenshots from the Android L preview release, but there will be way more to Android L than just the notification panel, settings, dialer, and calculator.

To get a better idea of what's in store for us, we went on a screenshot hunt for Google-created Material Design apps. Between various Google I/O sessions and the Material Design guidelines, the company has been dropping a ton of hints about what L will look like. After scouring all the design docs and I/O sessions, we threw together a gallery of the more revealing design examples.

A lot of these mockups are from the Material Design guidelines and (mostly) don't represent Google-branded products. You can see an example of this above, where the example e-mail app (left) doesn't have the correct color theme or action button, items have an extra line of text, and the app is missing some minor UI elements like stars and a timestamp.

The "generic" version of the app is still 90 percent of the way there, though, and this is the style of the majority of the screenshots we'll be looking at. Google is trying to show developers what it thinks an app should look like without spoiling its own designs, but as you can see above, Google apparently plans on sticking pretty close to these guidelines for its own designs. Do note that these apps are all works in progress, so things could change before release. Still, this screenshot collection is our best look at the wider Google app selection that is sure to come with Android L when it finally launches later this year.

When you're done checking out the gallery, there's a good addendum over at Android Police. The site just scored a few screenshots of the work-in-progress redesign of the Google Play Store.
