Android Wear Beta

Posted by Hoi Lam, Lead Developer Advocate, Android Wear

LG Watch Sport

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.

Notification Channels

In this update, users can choose the types of notifications they receive via an app through notification channels. This gives users finer-grained control than muting all notifications from the app. For notifications generated locally by Android Wear apps, users will be able to customise the notifications channel they want to see, right on their watch. Please refer to the Wear notification sample for more details. For notifications bridged from the phone, the phone notifications channel settings will dictate what is shown on the watch.


if (Bui   ld.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    mNotificationManager.createNotificationChannel(
        NotificationChannel("1001", "New Follower",
            NotificationManager.IMPORTANCE_DEFAULT))

    mNotificationManager.createNotificationChannel(
        NotificationChannel("1002", "Likes",
            NotificationManager.IMPORTANCE_LOW))
}

Background Limits

There are increased restrictions on background services. Developers should assume services can no longer run in the background without a visible notification. In addition, the background location update frequency will be reduced. Battery-saving best practices such as using JobScheduler should be adopted to ensure your app is battery-efficient and able to perform background tasks when possible.

Please give us your feedback

We expect this to be the only beta release before the final pr oduction release. Thank you for your feedback so far. Please submit any bugs you find via the Android Wear issue tracker. The earlier you submit them, the higher the likelihood that we can include the fixes in the final release.
