When Google first started releasing developer previews of new Android versions a few years ago, it was pretty rare to see any of the apps adopting new APIs until the new version was finalized. With Android O, there's a very visible change to that trend as many apps in Google's lineup have already taken features like Notification Channels to heart. Another brand new user-facing feature found support in the latest release of Play Movies & TV: Picture-in-Picture Mode.
The picture above was taken with the Android Messages app in the background while A Stork's Journey plays in a PiP window driven by Play Movies & TV. This is the third notable Google app to add support for Picture-in-Picture, following the version of YouTube included with the first developer preview and Duo, which gained support early last month.
If you're running either version of the Android O developer previews, Picture-in-Picture mode can still only be activated by a custom button added to the navigation bar through the System UI Tuner. It's a simple enough process, but it really shouldn't be necessary. During the Google I/O Keynote, it was said picture-in-picture mode would be activated by pressing the home button, but that behavior doesn't appear to work in either of the developer previews.
Picture-in-Picture is definitely one of the more popular user-facing additions in Android O, so it's pretty great to see it's getting attention in the apps that can really make the most of it.
The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
