WatchFaceService and WatchFace are a pair of classes intended to handle much of the boilerplate needed to implement a watch face without being too opinionated. The suggested structure of a WatchFaceService based watch face is:

Sub classes of WatchFaceService are expected to implement createWatchFace which is the factory for making WatchFaces. If the watch faces uses complications then createComplicationSlotsManager should be overridden. All ComplicationSlots are assumed to be enumerated up upfront and passed as a collection into ComplicationSlotsManager's constructor which is returned by createComplicationSlotsManager.

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

Watch face styling (color and visual look of watch face elements such as numeric fonts, watch hands and ticks, etc...) and companion editing is directly supported via UserStyleSchema and UserStyleSetting. To enable support for styling override createUserStyleSchema.

WatchFaceService can expose pre-populated style presets by overriding createUserStyleFlavors or via XML (see below). Each presents represents separate style configured with UserStyle and complication slot policies configured with androidx.wear.watchface.complications.DefaultComplicationDataSourcePolicy. The system will only access flavors if metadata tag is present in manifest:

    <meta-data
      android:name="androidx.wear.watchface.FLAVORS_SUPPORTED"
      android:value="true" />

WatchFaces are initially constructed on a background thread before being used exclusively on the ui thread afterwards. There is a memory barrier between construction and rendering so no special threading primitives are required.

To aid debugging watch face animations, WatchFaceService allows you to speed up or slow down time, and to loop between two instants. This is controlled by MOCK_TIME_INTENT intents with a float extra called "androidx.wear.watchface.extra.MOCK_TIME_SPEED_MULTIPLIE" and to long extras called "androidx.wear.watchface.extra.MOCK_TIME_WRAPPING_MIN_TIME" and "androidx.wear.watchface.extra.MOCK_TIME_WRAPPING_MAX_TIME" (which are UTC time in milliseconds). If minTime is omitted or set to -1 then the current time is sampled as minTime.

E.g., to make time go twice as fast: adb shell am broadcast -a androidx.wear.watchface.MockTime
--ef androidx.wear.watchface.extra.MOCK_TIME_SPEED_MULTIPLIER 2.0

To use the sample on watch face editor UI, import the wear:wear-watchface-editor-samples library and add the following into your watch face's AndroidManifest.xml:

<activity
  android:name="androidx.wear.watchface.editor.sample.WatchFaceConfigActivity"
  android:exported="true"
  android:label="Config"
  android:theme="@android:style/Theme.Translucent.NoTitleBar">
  <intent-filter>
    <action android:name="androidx.wear.watchface.editor.action.WATCH_FACE_EDITOR" />
    <category android:name=
        "com.google.android.wearable.watchface.category.WEARABLE_CONFIGURATION" />
    <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>
</activity>

To register a WatchFaceService with the system add a tag to the in your watch face's AndroidManifest.xml:

<service
  android:name=".MyWatchFaceServiceClass"
  android:exported="true"
  android:label="@string/watch_face_name"
  android:permission="android.permission.BIND_WALLPAPER">
  <intent-filter>
    <action android:name="android.service.wallpaper.WallpaperService" />
    <category android:name="com.google.android.wearable.watchface.category.WATCH_FACE" />
  </intent-filter>
  <meta-data
     android:name="com.google.android.wearable.watchface.preview"
     android:resource="@drawable/my_watch_preview" />
  <meta-data
    android:name="com.google.android.wearable.watchface.preview_circular"
    android:resource="@drawable/my_watch_circular_preview" />
  <meta-data
    android:name="com.google.android.wearable.watchface.wearableConfigurationAction"
    android:value="androidx.wear.watchface.editor.action.WATCH_FACE_EDITOR"/>
  <meta-data
    android:name="android.service.wallpaper"
    android:resource="@xml/watch_face" />
  <meta-data
    android:name=
       "com.google.android.wearable.watchface.companionBuiltinConfigurationEnabled"
    android:value="true" />
</service>

Multiple watch faces can be defined in the same package, requiring multiple tags.

By default the system will only allow the user to create a single instance of the watch face. You can choose to allow the user to create multiple instances (each with their own styling and a distinct WatchState.watchFaceInstanceId) by adding this meta-data to your watch face's manifest:

    <meta-data
      android:name="androidx.wear.watchface.MULTIPLE_INSTANCES_ALLOWED"
      android:value="true" />

A watch face can declare the UserStyleSchema, ComplicationSlots and UserStyleFlavors in XML. The main advantage is simplicity for the developer, however meta data queries (see androidx.wear.watchface.client.WatchFaceMetadataClient) are faster because they can be performed without having to bind to the WatchFaceService.

To use xml inflation, add an androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition meta date tag to your service:

    <meta-data
        android:name="androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition"
        android:resource="@xml/my_watchface_definition" />

And the linked xml/my_watchface_definition resource must contain a XmlWatchFace node. E.g.:

     <XmlWatchFace xmlns:android="http://schemas.android.com/apk/res/android"
             xmlns:app="http://schemas.android.com/apk/res-auto">
         <UserStyleSchema>
             <ListUserStyleSetting

If you use resources references to specify identifiers, they should be locale independent (i.e. translatable="false").

If you use XmlSchemaAndComplicationSlotsDefinition then you shouldn't override createUserStyleSchema or createComplicationSlotsManager. However if tags are defined then you must override getComplicationSlotInflationFactory in order to provide the CanvasComplicationFactory and where necessary edge complication ComplicationTapFilters.

Note the tag does not support configExtras because in general a Bundle can not be inflated from XML.

Note it is an error to define a XmlSchemaAndComplicationSlotsDefinition and not use it.

As of Wear OS 4, complications can provide data using dynamic values, that the platform evaluates continuously and sends the evaluated results to the watch face. Privileged watch faces that can utilize the unevaluated dynamic values, can include the privileged permission com.google.wear.permission.GET_COMPLICATION_DYNAMIC_VALUE in their manifest, which will tell the system to avoid pruning them from the ComplicationData, where they will show up in the relevant fields next to the evaluated values.

getBackgroundThreadHandler

Added in 1.0.0

Deprecated in 1.3.0-alpha07

fun getBackgroundThreadHandler(): Handler

Returns the lazily constructed background thread Handler. During initialization createUserStyleSchema, createComplicationSlotsManager and createWatchFace are posted on this handler.

getUiThreadHandler

Deprecated in 1.3.0-alpha07

fun getUiThreadHandler(): Handler

Returns the ui thread Handler.

onConfigurationChanged

open fun onConfigurationChanged(newConfig: Configuration): Unit

final fun onCreateEngine(): WallpaperService.Engine

Creates an interactive engine for WallpaperService.

Protected functions

createComplicationSlotsManager

Added in 1.0.0

Deprecated in 1.3.0-alpha07

@WorkerThread
protected open fun createComplicationSlotsManager(
    currentUserStyleRepository: CurrentUserStyleRepository
): ComplicationSlotsManager

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
`currentUserStyleRepository: CurrentUserStyleRepository`	The `CurrentUserStyleRepository` constructed using the `UserStyleSchema` returned by `createUserStyleSchema`.

Returns
`ComplicationSlotsManager`	The `ComplicationSlotsManager` to pass into `createWatchFace`.

createUserStyleFlavors

Added in 1.2.0

Deprecated in 1.3.0-alpha07

@WorkerThread
protected open fun createUserStyleFlavors(
    currentUserStyleRepository: CurrentUserStyleRepository,
    complicationSlotsManager: ComplicationSlotsManager
): UserStyleFlavors

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
`currentUserStyleRepository: CurrentUserStyleRepository`	The `CurrentUserStyleRepository` constructed using the `UserStyleSchema` returned by `createUserStyleSchema`.
`complicationSlotsManager: ComplicationSlotsManager`	The `ComplicationSlotsManager` returned by `createComplicationSlotsManager`

Returns
`UserStyleFlavors`	The `UserStyleFlavors`, which is exposed to the system.

createUserStyleSchema

Added in 1.0.0

Deprecated in 1.3.0-alpha07

@WorkerThread
protected open fun createUserStyleSchema(): UserStyleSchema

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.

Returns
`UserStyleSchema`	The `UserStyleSchema` to create a `CurrentUserStyleRepository` with, which is passed to `createComplicationSlotsManager` and `createWatchFace`.

createWatchFace

@WorkerThread
protected abstract suspend fun createWatchFace(
    surfaceHolder: SurfaceHolder,
    watchState: WatchState,
    complicationSlotsManager: ComplicationSlotsManager,
    currentUserStyleRepository: CurrentUserStyleRepository
): WatchFace

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
`surfaceHolder: SurfaceHolder`	The `SurfaceHolder` to pass to the `Renderer`'s constructor.
`watchState: WatchState`	The `WatchState` for the watch face.
`complicationSlotsManager: ComplicationSlotsManager`	The `ComplicationSlotsManager` returned by `createComplicationSlotsManager`.
`currentUserStyleRepository: CurrentUserStyleRepository`	The `CurrentUserStyleRepository` constructed using the `UserStyleSchema` returned by `createUserStyleSchema`.

Returns
`WatchFace`	A `WatchFace` whose `Renderer` uses the provided `surfaceHolder`.

getComplicationSlotInflationFactory

Added in 1.1.0

Deprecated in 1.2.0

@WorkerThread
protected open fun getComplicationSlotInflationFactory(): ComplicationSlotInflationFactory?

Used when inflating ComplicationSlots from XML (i.e the manifest contains androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition metadata) to provide a ComplicationSlotInflationFactory which provides the CanvasComplicationFactory and where necessary edge complication ComplicationTapFilters needed for inflating ComplicationSlots.

If an androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition metadata tag is defined for your WatchFaceService 's manifest, and your XML includes tags then you must override this method.

getComplicationSlotInflationFactory

Added in 1.2.0

Deprecated in 1.3.0-alpha07

@WorkerThread
protected open fun getComplicationSlotInflationFactory(
    currentUserStyleRepository: CurrentUserStyleRepository
): ComplicationSlotInflationFactory

If an androidx.wear.watchface.XmlSchemaAndComplicationSlotsDefinition metadata tag is defined for your WatchFaceService 's manifest, and your XML includes tags then you must override this method. A NotImplementedError exception will be thrown if you don't.

Parameters
`currentUserStyleRepository: CurrentUserStyleRepository`	The `CurrentUserStyleRepository` constructed using the `UserStyleSchema` returned by `createUserStyleSchema`.
