Google has now released Android O Developer Preview 4. This is expected to be the final build before the official release of Google’s new mobile OS.
The official release of Android O is expected some time next month. The official line from Google is that it is coming this summer.
Developer Preview 4 is a release candidate build of Android O that you can use to complete your development and testing in time for the upcoming official release. It includes the final system behaviors, the latest bug fixes and optimizations, and the final APIs (API level 26) already available since Developer Preview 3.
We’re releasing the Developer Preview 4 device system images today, together with the stable version of the Android 26.0.0 Support Library. Incremental updates to the SDK, tools, and Android Emulator system images are on the way over the next few days.
