Google releases Android O Developer Preview

Google has released the first Developer Preview for Android O, which is probably going to be released somewhere in the Fall. There’s a lot changes in this one, but the biggest one is probably the limits Android O is going to place on applications running in the background.

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. Check out the documentation on background
execution limits
and background location limits for details.

There’s more – improvements in keyboard navigation, Navigation Channels for managing notifications, picture-in-picture on smartphones, wide-gamut colour support for applications, several new Java 8 features, and more. A big one for audio people: Sony has contributed a lot of work to audio in Android O, adding the LDAC wireless audio codec.

It’s available on the usual Nexus devices.
