Android O Developer Preview 3 Released
The third Developer Preview of Android O has been released by Google and for those who have registered devices in the Android Beta Program, you should start seeing the update hit your devices. DP3 arrived earlier than expected as Google had slated this for late June. The early June release signals that the company is overall pretty pleased with where it stands in its development and also gives developers more time to prepare their apps.
A key element of the DP3 release is the finalized APIs for developers. That means they can get started on updating or adding functionality to their apps based on these APIs, knowing they are not going to change between now and the final release. That means you can expect over the next few months to see apps start noting updates in the Play Store with support for Android O prior to the release.
