WatchState

The current user interruption settings. See NotificationManager. This is initially null because the watch face is created before the system has sent the state. Based on the value the watch face should adjust the amount of information it displays. For example, if it displays the number of pending emails, it should hide it if interruptionFilter is equal to NotificationManager.INTERRUPTION_FILTER_NONE. interruptionFilter can be NotificationManager.INTERRUPTION_FILTER_NONE, NotificationManager.INTERRUPTION_FILTER_PRIORITY, NotificationManager.INTERRUPTION_FILTER_ALL, NotificationManager.INTERRUPTION_FILTER_ALARMS, or NotificationManager.INTERRUPTION_FILTER_UNKNOWN.

Whether or not the watch is in ambient mode. This is initially null because the watch face is created before the system has sent the state. The order in which ambient vs style changes are reported is not guaranteed. Likewise the order of isAmbient flow callbacks and Renderer.CanvasRenderer.render or Renderer.GlesRenderer.render calls is not defined. For rendering please refer to RenderParameters.drawMode instead of isAmbient because you might receive requests for rendering non-ambient frames while the watch is ambient (e.g. editing from the companion phone).

Whether or not we should conserve power due to a low battery which isn't charging. This is initially null because the watch face is created before the system has sent the state. Only valid if android.support.wearable.watchface.WatchFaceStyle.hideNotificationIndicator is true.

Whether or not the watch face is visible. This is initially null because the watch face is created before the system has sent the state.

Whether or not the watch hardware supports low bit ambient support.

Whether or not the watch hardware supports burn in protection.

UTC reference time for previews of analog watch faces in milliseconds since the epoch.

UTC reference time for previews of digital watch faces in milliseconds since the epoch.

the size, in pixels, of the chin or zero if the device does not have a chin. A chin is a section at the bottom of a circular display that is visible due to hardware limitations.

Whether or not this is a headless watchface.

The ID associated with the watch face instance. Note there may be more than one instance associated with a WatchFaceService. See androidx.wear.watchface.client.WatchFaceId for more details.
