Google has announced a new Android Wear beta, the software is based on the latest release of Android, Android 8.0 Oreo.
The new Android Wear beta will only be available for the LG Watch Sport at first, of course this could possibly change in the future.
Today, we are launching the beta of the next Android Wear update. As we mentioned at Google I/O, this will mainly be a technical upgrade to API 26 with enhancements to background limits and notification channels. LG Watch Sport users can go to this webpage to sign up and the factory image will automatically be downloaded to the watch you enroll. As this is a beta, please be sure to review the known issues before enrolling. If you don’t have a watch to test on, you can use the Android emulator. For developers working with Android Wear for China, an updated emulator image is also available.
You can find out full information about the new beta version of Google’s Android Wear OS over at the Android Developers website at the link below.
