The new mobile OS aims to improve battery life and device performance while offering new features like picture-in-picture display, Wi-Fi Aware support, and moreĀ  Android O introduces a number of new features and APIs to use in your apps. Here’s are just a few new things for you to start trying in this first Developer Preview:

Background limits: 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.

Notification channels: Android O also introduces notification channels, which are new app-defined categories for notification content. Channels let developers give users fine-grained control over different kinds of notifications

Autofill APIs: We are making this work more easily across the ecosystem by adding platform support for autofill.

PIP for handsets and new windowing features: Picture in Picture (PIP) display is now available on phones and tablets, so users can continue watching a video while they’re answering a chat or hailing a car. Apps can put themselves in PiP mode from the resumed or a pausing state where the system supports it

Adaptive icons: You can now create adaptive icons that the system displays in different shapes, based on a mask selected by the device.

Wide-gamut color for apps: Android developers of imaging apps can now take advantage of new devices that have a wide-gamut color capable display (AdobeRGB, Pro Photo RGB, DCI-P3, etc.).

Connectivity: Android O now also supports high-quality Bluetooth audio codecs such as LDAC codec. We’re also adding new Wi-Fi features as well

Keyboard navigation: With the advent of Google Play apps on Chrome OS and other large form factors, we’re seeing a resurgence of keyboard navigation use within these apps.

AAudio API for Pro Audio: AAudio is a new native API that’s designed specifically for apps that require high-performance, low-latency audio.

WebView enhancements: In Android O, we’re enabling multiprocess mode by default and adding an API to let your app handle errors and crashes, for enhanced security and improved app stability.

Java 8 Language API improvements: Android now supports several new Java Language APIs, including the new java.time API. In addition, the Android Runtime is faster than ever before, with improvements of up to 2x on some application benchmarks.

Partner platform contributions: Hardware manufacturers and silicon partners have accelerated fixes and enhancements to the Android platform in the O release. For example, Sony has contributed more than 30 feature enhancements including the LDAC codec and 250 bug fixes to Android O.
