Google launches Android O Developer Preview 4 with final system behaviors


In the fourth Android O developer preview, tapping on the Android version multiple times in your settings menu will still bring up that pretty orange "O" logo that we've seen in the past.

It's been almost two months since Google last released a new Android O Developer Preview update, but today that drought is finally ending. Google has slated the final version for release "later this summer" (in Q3 2017).

Google released the initial Android O Developer Preview back in March, and I've been using it ever since on my Pixel XL.

Developers can look forward to incremental updates to the SDK, tools, and Android Emulator system images are said to be coming in the next few days. The official end of summer is September 22, so we suspect Android O will hit sometime before that date.

Google launched the first Android O developer preview in March, the second developer preview in May at its I/O 2017 developer conference, and the the third developer preview in June. You can enroll in the Android Beta Program right here if you're not already in it.

We're also introducing a new version of Android Testing Support Library that includes new features like Android Test Orchestrator, Multiprocess Espresso, and more. Like the previous build, it also includes finalized system behaviors, along with the latest bug fixes and optimizations to ensure smooth performance on modern smartphone hardware.
