Android Wear 2.0 for China - Developer Preview

Posted by Hoi Lam, Developer Advocate

Today at Google Developer Day China, we are happy to announce a developer preview of Android Wear 2.0 for developers creating apps for China. Android Wear 2.0 is the biggest update since our partners launched their first devices in China last year.

We're making a Developer Preview available today and plan to release additional updates in the coming months. Please send us your feedback by filing bugs or posting in our Android Wear Developers community.

Developing for the Chinese Market

With Android Wear 2.0, apps can access the internet directly on Android Wear devices. As a result, for the majority of apps, having a companion phone application is no longer necessary. This means that most developers creating apps for Android Wear 2.0 may no longer need to import the Google Play services library.

There are two situations where developers will need to import Google Play services for China:

  • Apps that require direct interaction with the paired mobile device - some experiences require Android Wear to connect directly to a paired phone. In this case, the Data Layer API introduced in Android Wear 1.0 will continue to function.
  • New FusedLocationProvider for China - we have added location detection to the SDK for Chinese developers. With the user's permission, your app can receive location updates via the FusedLocationProvider.

You can find more details about how to import the China compatible version of Google Play services library here.

Product testing for Android Wear 2.0 for China

The Android Wear 2.0 Developer Preview includes an updated SDK with tools, and system images for testing using the Huawei Watch.

To get started, follow these steps:

We will update this developer preview over the next few months based on your feedback. The sooner we hear from you, the more we can include in the final release, so don't be shy!

Android Wear 2.0 中国版 - 开发者预览版

编辑: 林海泉, Android Wear 开发平台负责人

今天在上海举办的Google 开发者大会上,我们正式宣布了一款专门针对中国市场的Android Wear 2.0 开发者预览版。Android Wear 2.0系统,将是自我们的合作伙伴首次发布手表产品以来最重大的更新。

开发者预览版已于今日正式上线。与此同时,我们也计划在未来的几个月内持续进行更新。请您将您遇到的问题在此提交反馈,或者在我们的Android Wear开发者论坛发表意见。


在Android Wear 2.0系统中,应用可以由Android Wear手表直接连接至互联网。因此,对于大多数应用来说,手机端的伴侣应用也就变得不再必要。这也意味着,多数为Android Wear 2.0开发应用的开发者将不再需要引用Google Play services客户端库。

目前,在两个情况下开发者仍然需要引入Google Play Services客户端库来为中国市场开发应用:

  • 需要与手机直接进行通信的应用 - 有一些用例需要Android Wear手表与已配对手机直接连接。在这种情况下,Android Wear 1.0中引入的Data Layer API仍然可以继续使用。
  • 使用 FusedLocationProvider - 我们在最新的中国版SDK中加入了定位的支持。在用户的许可下,您的应用可以通过FusedLocationProvider来接收定位更新。

您可以在这里找到关于如何引入与中国版兼容的Google Play service的更多信息。
