According to a report coming from AndroidPolice's David Ruddock, Google might have pushed the release of Android O for Pixel beyond the August 21 date. The company has also introduced a new version of Android Testing Support Library that includes features like Android Test Orchestrator, Multiprocess Espresso, and more. Earlier info had said that the newest version of Android will receive it's name on the 21st ( on the day of solar eclipse) and now we hear that it will be launched as well on the same day. Google has been working hard to refine the underlying operating system for improved battery efficiency and overall ease of use, and the new Android O feature set reflects this. Putting two and two together, it's really not that hard to predict what Android O will be called: it's going to be Oreo. Earlier rumors have revealed that this year Google will be releasing the Android O earlier this year.
Android users are often left wanting more when it comes to their phone's camera. Ruddock is of the view that the official name of Android 8.0 will be declared on August 21, the day of the solar eclipse.
Google's next big release - Android O beta - has entered Developer Preview 2. Another possible name for Android O is Oatmeal Cookie, evidence of this has already been found inside Android's code. Android O, back at Google I/O this year. It could be days or even weeks.
Of course unless you have a Pixel or Nexus phone you're unlikely to see Android O for a good while yet - get in touch with your Android phone manufacturer to see if and when you can expect to see the latest version of the mobile OS on your own handset.
