Android has released Preview 1 for Android 8.x – or O as its being called and Oreo. The Developer Preview 1 is for registered developers with a sacrificial device — a Pixel or recent Nexus 5X/6P lying around. It is to make sure that developers and hardware makers are prepared. It outlines the timeline with a total of 4 previews and an anticipated Q3, 2017 release.
Android O will feature less background polling and updating for improved battery life in order to stop apps that eat up the battery. The Developers conference was informed,
Building on the work we began in Nougat, Android O puts a big priority on improving a user's battery life and the device's interactive performance. To make this possible, we've put additional automatic limits on what apps can do in the background, in three main areas: implicit broadcasts, background services, and location updates. These changes will make it easier to create apps that have minimal impact on a user's device and battery. Background limits represent a significant change in Android, so we want every developer to get familiar with them.
Google released its Android Security 2016 Year in Review as well. It is expected that you won’t be able to avoid some form of biometric or secure login, all will be encrypted and security updates sent from the company will be binding.
