WatchFaceRuntimeService


public abstract class WatchFaceRuntimeService extends WatchFaceService


WatchFaceRuntimeService is a special kind of WatchFaceService, which loads the watch face definition from another resource only watch face package (see the resourceOnlyWatchFacePackageName parameter passed to createUserStyleSchema, createComplicationSlotsManager, createUserStyleFlavors and createWatchFace).

WatchFaceRuntimeServices are required to be stateless as multiple can be created in parallel. If per instance state is required please use StatefulWatchFaceRuntimeService.

Note because a WatchFaceRuntimeService loads it's resources from another package, it will need the following permission:

    <uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"
tools:ignore="QueryAllPackagesPermission" />

Currently Wear OS only supports the runtime for the Android Watch Face Format (see https://developer.android.com/training/wearables/wff for more details).

Note only one watch face definition per resource only watch face package is supported.

Added in 1.3.0-alpha04
protected final @NonNull ComplicationSlotsManager createComplicationSlotsManager(
    @NonNull CurrentUserStyleRepository currentUserStyleRepository
)

If the WatchFaceService's manifest doesn't define a androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta data tag then override this factory method to create a non-empty ComplicationSlotsManager. This manager will be passed to createUserStyleFlavors and createWatchFace. This will be called from a background thread but the ComplicationSlotsManager should be accessed exclusively from the UiThread afterwards.

Parameters
@NonNull CurrentUserStyleRepository currentUserStyleRepository

The CurrentUserStyleRepository constructed using the UserStyleSchema returned by createUserStyleSchema.

createComplicationSlotsManager

Added in 1.2.0
@WorkerThread
protected abstract @NonNull ComplicationSlotsManager createComplicationSlotsManager(
    @NonNull CurrentUserStyleRepository currentUserStyleRepository,
    @NonNull String resourceOnlyWatchFacePackageName
)

If the WatchFaceService's manifest doesn't define an androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta data tag then override this factory method to create a non-empty ComplicationSlotsManager. This manager will be passed to createUserStyleFlavors and createWatchFace. This will be called from a background thread but the ComplicationSlotsManager should be accessed exclusively from the UiThread afterwards.

Parameters
@NonNull CurrentUserStyleRepository currentUserStyleRepository

The CurrentUserStyleRepository constructed using the UserStyleSchema returned by createUserStyleSchema.

@NonNull String resourceOnlyWatchFacePackageName

The android package from which the watch face definition should be loaded.

createUserStyleFlavors

Added in 1.3.0-alpha04
protected final @NonNull UserStyleFlavors createUserStyleFlavors(
    @NonNull CurrentUserStyleRepository currentUserStyleRepository,
    @NonNull ComplicationSlotsManager complicationSlotsManager
)

If the WatchFaceService's manifest doesn't define a androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta data tag then override this factory method to create non-empty UserStyleFlavors. This is called on a background thread. The system reads the flavors once and changes may be ignored until the APK is updated. Metadata tag "androidx.wear.watchface.FLAVORS_SUPPORTED" should be added to let the system know the service supports flavors.

Parameters
@NonNull CurrentUserStyleRepository currentUserStyleRepository

The CurrentUserStyleRepository constructed using the UserStyleSchema returned by createUserStyleSchema.

@NonNull ComplicationSlotsManager complicationSlotsManager

The ComplicationSlotsManager returned by createComplicationSlotsManager

Returns
@NonNull UserStyleFlavors

The UserStyleFlavors, which is exposed to the system.

    @NonNull String resourceOnlyWatchFacePackageName
)

If the WatchFaceService's manifest doesn't define an androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta data tag then override this factory method to create non-empty UserStyleFlavors. This is called on a background thread. The system reads the flavors once and changes may be ignored until the APK is updated.

protected final @NonNull UserStyleSchema createUserStyleSchema()

If the WatchFaceService's manifest doesn't define an androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta data tag then override this factory method to create a non-empty UserStyleSchema. A CurrentUserStyleRepository constructed with this schema will be passed to createComplicationSlotsManager, createUserStyleFlavors and createWatchFace. This is called on a background thread.

createUserStyleSchema

Added in 1.2.0
@WorkerThread
protected abstract @NonNull UserStyleSchema createUserStyleSchema(@NonNull String resourceOnlyWatchFacePackageName)

If the WatchFaceService's manifest doesn't define a androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta data tag then override this factory method to create a non-empty UserStyleSchema.

Parameters
@NonNull String resourceOnlyWatchFacePackageName

The android package from which the watch face definition should be loaded.

createWatchFace

protected final @NonNull WatchFace createWatchFace(
    @NonNull SurfaceHolder surfaceHolder,
    @NonNull WatchState watchState,
    @NonNull ComplicationSlotsManager complicationSlotsManager,
    @NonNull CurrentUserStyleRepository currentUserStyleRepository
)

Override this factory method to create your WatchFaceImpl. This method will be called by the library on a background thread, if possible any expensive initialization should be done asynchronously. The WatchFace and its Renderer should be accessed exclusively from the UiThread afterwards. There is a memory barrier between construction and rendering so no special threading primitives are required.

Warning the system will likely time out waiting for watch face initialization if it takes longer than MAX_CREATE_WATCHFACE_TIME_MILLIS milliseconds.

Parameters
@NonNull SurfaceHolder surfaceHolder

The SurfaceHolder to pass to the Renderer's constructor.

@NonNull WatchState watchState

The WatchState for the watch face.

@NonNull ComplicationSlotsManager complicationSlotsManager

The ComplicationSlotsManager returned by createComplicationSlotsManager.

@NonNull CurrentUserStyleRepository currentUserStyleRepository

The CurrentUserStyleRepository constructed using the UserStyleSchema returned by createUserStyleSchema.

Returns
@NonNull WatchFace

A WatchFace whose Renderer uses the provided surfaceHolder.

createWatchFace

@WorkerThread
protected abstract @NonNull WatchFace createWatchFace(
    @NonNull SurfaceHolder surfaceHolder,
    @NonNull WatchState watchState,
    @NonNull ComplicationSlotsManager complicationSlotsManager,
    @NonNull CurrentUserStyleRepository currentUserStyleRepository,
    @NonNull String resourceOnlyWatchFacePackageName
)

Override this factory method to create your WatchFaceImpl. This method will be called by the library on a background thread, if possible any expensive initialization should be done asynchronously. The WatchFace and its Renderer should be accessed exclusively from the UiThread afterwards. There is a memory barrier between construction and rendering so no special threading primitives are required.

Warning the system will likely time out waiting for watch face initialization if it takes longer than WatchFaceService.MAX_CREATE_WATCHFACE_TIME_MILLIS milliseconds.

Parameters
@NonNull SurfaceHolder surfaceHolder

The SurfaceHolder to pass to the Renderer's constructor.

@NonNull WatchState watchState

The WatchState for the watch face.

@NonNull ComplicationSlotsManager complicationSlotsManager

The ComplicationSlotsManager returned by createComplicationSlotsManager.

@NonNull CurrentUserStyleRepository currentUserStyleRepository

The CurrentUserStyleRepository constructed using the UserStyleSchema returned by createUserStyleSchema.

@NonNull String resourceOnlyWatchFacePackageName

The android package from which the watch face definition should be loaded.

Returns
@NonNull WatchFace

A WatchFace whose Renderer uses the provided surfaceHolder.
