AmbientMode
class AmbientMode : Fragment
Use this as a headless Fragment to add ambient support to an Activity on Wearable devices.
The application that uses this should add the WAKE_LOCK permission to its manifest.
The primary entry point for this code is the attachAmbientSupport method. It should be called with an Activity as an argument and that Activity will then be able to receive ambient lifecycle events through an AmbientCallback. The Activity will also receive a AmbientController object from the attachment which can be used to query the current status of the ambient mode. An example of how to attach AmbientMode to your Activity and use the AmbientController can be found below:
AmbientMode.AmbientController controller = AmbientMode.attachAmbientSupport(this); boolean isAmbient = controller.isAmbient();

Constants
const val EXTRA_BURN_IN_PROTECTION = "com.google.android.wearable.compat.extra.BURN_IN_PROTECTION": String!
Property in bundle passed to AmbientCallback#onEnterAmbient(Bundle) to indicate whether burn-in protection is required. When this property is set to true, views must be shifted around periodically in ambient mode. To ensure that content isn't shifted off the screen, avoid placing content within 10 pixels of the edge of the screen. Activities should also avoid solid white areas to prevent pixel burn-in. Both of these requirements only apply in ambient mode, and only when this property is set to true.
const val EXTRA_LOWBIT_AMBIENT = "com.google.android.wearable.compat.extra.LOWBIT_AMBIENT": String!
Property in bundle passed to AmbientCallback#onEnterAmbient(Bundle) to indicate whether the device has low-bit ambient mode. When this property is set to true, the screen supports fewer bits for each color in ambient mode. In this case, activities should disable anti-aliasing in ambient mode.
const val FRAGMENT_TAG = "android.support.wearable.ambient.AmbientMode": String!
Fragment tag used by default when adding AmbientMode to add ambient support to an Activity.

java-static fun <T : Activity?>attachAmbientSupport(activity: T!): AmbientMode.AmbientController!
Attach ambient support to the given activity. Calling this method with an Activity implementing the AmbientCallbackProvider interface will provide you with an opportunity to react to ambient events such as onEnterAmbient. Alternatively, you can call this method with an Activity which does not implement the AmbientCallbackProvider interface and that will only enable the auto-resume functionality. This is equivalent to providing (@code null} from the AmbientCallbackProvider.
