Clockwise is a watch face framework for Android Wear developed by ustwo. It extends the Android Wear Watch Face API and provides base classes and helpers for quickly and correctly developing watch faces. This includes properly handling the various modes of operation, hardware constraints, changes in date/time/time zone, access to data, and performance considerations.
ustwo worked with Google to develop the first watch faces on the Android Wear platform, and in doing so, we learned a great deal and identified the benefit of extending the existing watch face API into an open source framework. The purpose of Clockwise is to help developers more easily consider the inherent nuances in developing watch faces on the Android Wear platform, including varying hardware specifications and battery life conservation. The goal is that by utilizing the Clockwise development framework in conjunction with the Watch Face design guidelines (co-created with ustwo), developers can enhance the user's experience on Android Wear.
Here are links to the ustwo's existing watch faces in the Play Store, all built on top of Clockwise:
We are working diligently to bring the following functionality to Clockwise:
- 3rd party/phone data integration (e.g. weather, fitness, etc.)
- you can currently utilize the ConnectedWatchFace to help achieve this, however we plan to completely manage the communication layer and allow developers to just focus on writing data update code (e.g. a weather web service) and reacting to it in a callback in the watch face.
- Custom watch face configuration
- also currently possible (see our example watch face, Museum) utilizing ConnectedWatchFace, however we plan to extend and allow developers to focus on creating mobile and wearable configuration activities and leaving the persistence, syncing, etc. to Clockwise.
If you would like to contribute to Clockwise, please feel free to fork the repository and submit pull requests. When submitting code, please be sure to follow the Android Code Style Guidelines.
