DevBytes: Watch Faces for Android Wear

Watch faces in Android Wear leverage a dynamic digital canvas to tell time using colors, animations, and relevant contextual information. The Android Wear companion app provides watch faces with different styles and shapes. When users select one of the available watch faces on the wearable or on the companion app, the wearable device previews the watch face and lets the user set configuration options.

手表表盘使用动态的数字的画布去用颜色，动画显示时间，和一些实质性的上下文信息。 Android Wear companion app提供了不同的风格和尺寸的表盘。当用户选择了一个可以用的表盘在手表上或者相关的app 上面的时候。手表设备预览了手表的表盘并且让用户设置配置选项。

Android Wear enables you to create custom watch faces for Wear devices. When users install a handheld app that contains a wearable app with watch faces, they become available in the Android Wear companion app on the handheld device and in the watch face picker on the wearable device.

Android 手表让你可以自定义手表的表盘。当用户安装了含有手表表盘应用的手机应用的时候。他们就可以在手机中的手表相应的应用选择相应的表盘。

This class teaches you to implement custom watch faces and to package them inside a wearable app. This class also covers design considerations and implementation tips to ensure that your designs integrate with system UI elements and are power-efficient.

这个课程叫你去实现自定义的表盘，并且去将他们打包在手机的应用中。这个课程还包含了设计考虑点和实现小提示去保证你的设计可以整合到系统的UI项目中并且是电源高效的。

Note: We recommend using Android Studio for Android Wear development, as it provides project setup, library inclusion, and packaging conveniences. This training assumes you are using Android Studio.

注意：我们建议使用android Studio
