Version 1.3.0-alpha03

August 24, 2022

androidx.wear:wear:1.3.0-alpha03 is released. Version 1.3.0-alpha03 contains these commits.

New Features

  • ArcLayout now supports expansion weights which operate in a similar way to regular Layout weights. This means you can specify the relative size of child elements without having to compute their angles directly. We’ve also added a best effort MaxAngleDegrees which is respected when expanding child elements with weights. E.g. you could clamp the arc with several children with weights to 90 degrees, this would also respect the space taken by any non-expanded elements..

API Changes

  • We've added weight to ArcLayout.LayoutParams which allows a widget to expand to fill the available space, if there's more than one widget then their share of the available space is proportional to their weight. In addition we've added ArcLayout.setMaxAngleDegrees so you can for example cap the expansion at 90 degrees (NB this does not affect layout of any fixed sized child widgets). Finally ArcLayout.Widget now has setSweepAngleDegrees which allows the ArcLayout to inform a Widget with a non-zero weight of its size. (I75f24)
  • Updated nullability of setColorFilter(I99ddf, b/236498063)

  • UserStyleOption.getOptionForId now accepts UserStyleOption.Id instead of a byte array. (I469be)
  • Provide constants BooleanOption.TRUE and BooleanOption.FALSE and disallow instance creation (I46e09)
  • Methods in wear-watchface-client that can throw RemoteException have now been annotated accordingly. (Ib8438)
  • For consistency we've renamed EditorSession.createOnWatchEditingSession to createOnWatchEditorSession, similarly createHeadlessEditingSession is now createHeadlessEditorSession. Their guava wrappers have also been renamed. (I1526b)
  • EditorSession is now an interface and ListenableEditorSession.commitChangesOnClose is now properly delegated. (I7dc3e)
  • We now reject any user style schema that has settings or options with conflicting IDs (Ic2715)
  • We have added an overloaded UserStyle.get which accepts UserStyleSetting.Id. (I2aa0f)

Version 1.0.0-alpha18

July 21, 2021

androidx.wear:wear-*:1.0.0-alpha18 is released. Version 1.0.0-alpha18 contains these commits.

API Changes

  • We moved ComplicationHelperActivity to androidx.wear:wear-watchface library. (I39e76)
  • For consistency and clarity, ComplicationProvider has been renamed to ComplicationDataSource and all classes with Provider in their name have been similarly renamed. (Iaef0b)
  • CanvasComplication.isHighlighted has been moved into RenderParameters.pressedComplicationSlotIds this is a step towards making CanvasComplication stateless. To support this change CanvasComplication.render now also takes the slotId as a parameter and we now pass the ComplicationSlot into GlesTextureComplication. (I50e6e)
  • We have added headlessDeviceConfig to EditorRequest, if non null this parameter is used to construct a headless instance to back the EditorSession rather than acting on the interactive instance. This allows the editor to be invoked for a watch face that isn't the current one. (I0a820)
  • We've added an experimental WatchFaceMetadataClient which allows efficient retrieval of static watch face metadata such as the UserStyleSchema and fixed details about ComplicationSlots. (I6bfdf)
  • We have renamed CanvasRenderer.uiThreadInit to init. (I6fff9)
  • We've added PreviewScreenshotParams an optional new parameter for EditorRequest which instructs EditorSession to take a preview screenshot on commit with these parameter. The preview image is exposed on EditorState.previewImage. (Ic2c16)

Bug Fixes

  • Developers no longer need to add ComplicationHelperActivity to their own manifest. (I6f0c2)

Version 1.0.0-alpha17

June 30, 2021

androidx.wear:wear-*:1.0.0-alpha17 is released. Version 1.0.0-alpha17 contains these commits.

New Features

  • In GlesRenderer, makeUiThreadContextCurrent and makeBackgroundThreadContextCurrent have been replaced by runUiThreadGlCommands and runBackgroundThreadGlCommands which both accept a Runnable. The library ensures that only one GL command runnable is executing at any given time.

  • To make UiThread initialziaion easier we’ve added CanvasRenderer.uiThreadInit which is called once on the UiThread before any calls to render. We’ve also added onRendererCreated to CanvasComplication which makes it easier for Renderer and CanvasComplication to share state.

  • For clarity we have renamed Complication to ComplicationSlot and complicationId to either complicationSlotId or complicationInstanceId depending on usage

API Changes

  • For clarity we have renamed Complication to ComplicationSlot and complicationId to either complicationSlotId or complicationInstanceId depending on usage. Classes using Complication have similarly been renamed e.g. ComplicationsManager is now called ComplicationSlotsManager. (I4da44)
  • In GlesRenderer makeUiThreadContextCurrent and makeBackgroundThreadContextCurrent have been replaced by runUiThreadGlCommands and runBackgroundThreadGlCommands which both accept a Runnable. These functions are only needed if you need to make GL calls outside of render, runBackgroundThreadGlCommands and onUiThreadGlSurfaceCreated. This is required because there can be multiple GlesRenderers each with their own contexts in the same process, potentially from different watch faces. In addition access to the shared current GL context is now synchronized. (I04d59)
  • We have added CanvasRenderer.uiThreadInit which is called once on the UiThread before any calls to render. Also for clarity in GlesRenderer we have renamed onGlContextCreated to onBackgroundThreadGlContextCreated, and onGlSurfaceCreated to onUiThreadGlSurfaceCreated. (If86d0)
  • HeadlessWatchFaceClient & InteractiveWatchFaceClient getComplicationsSlotState has been renamed to getComplicationSlotsState. In ComplicationSlot: createRoundRectComplicationBuilder, createBackgroundComplicationBuilder, and createEdgeComplicationBuilder have been renamed to createRoundRectComplicationSlotBuilder, createBackgroundComplicationSlotBuilder, and createEdgeComplicationSlotBuilder respectively. (Ib9adc)
  • We have added onRendererCreated to CanvasComplication which makes it easier for Renderer and CanvasComplication to share state. (I5e1ac)

Version 1.0.0-alpha16

June 16, 2021

androidx.wear:wear-*:1.0.0-alpha16 is released. Version 1.0.0-alpha16 contains these commits.

New Features

  • We’ve fixed a number of bugs related to the recent threading model changes as well as addressing other issues with the on watch face editor.

Bug Fixes

  • Prevent NPE in onComplicationProviderChooserResult (b/189594557)
  • Fix issues with stale surfaces and drawBlack (b/189452267)
  • Fix race in accessing complicationsManager.watchState (b/189457893)
  • Fix background thread lifetime bug (b/189445428)
  • Fix Pre-R Watch face Editor issues (b/189126313)
  • Don't update direct boot params for editor style changes (b/187177307)

Version 1.0.0-alpha15

June 2, 2021

androidx.wear:wear-*:1.0.0-alpha15 is released. Version 1.0.0-alpha15 contains these commits.

New Features

The majority of watch face initialization is now done on a background thread, however after loading all watch face rendering etc is done on the UiThread. There is a memory barrier between loading and rendering so most user watch faces don’t need to do anything special. Watch faces using GLES may be an exception since the context is thread specific and we create two linked contexts so it’s possible to upload GL resources (e.g. textures and shaders) on the background thread and use them on the UiThread.

We have split the construction of watchfaces into three functions: createUserStyleSchema, createComplicationsManager and createWatchFace. We assume that createUserStyleSchema and createComplicationsManager are fast and createWatchFace may take some time to load assets. Taking advantage of this we have introduced WatchFaceControlClient.getDefaultProviderPoliciesAndType which returns a map of Complication Ids to DefaultComplicationProviderPolicies and the default ComplicationType. This is faster than creating a headless instance since it doesn’t need to fully initialize the watch face to perform the query.

Finally complications are now constructed with a CanvasComplicationFactory which allows for lazy construction of the CanvasComplication renderers.

API Changes

  • Replaced @TargetApi with @RequiresApi. (I0184a, b/187447093, b/187447094)
  • We have introduced WatchFaceControlClient.getDefaultProviderPoliciesAndType which returns a map of Complication Ids to DefaultComplicationProviderPolicies and the default ComplicationType. Where possible a fast path is used that avoids fully constructing a watch face. To facilitate this the WatchFaceService API has had to change with two new methods being: createUserStyleSchema and createComplicationsManager the results of which are passed into createWatchFace. In addition Complications are now constructed with a CanvasComplicationFactory which allows for lazy construction of the CanvasComplication renderers. (Iad6c1)
  • We have removed MOST_RECENT_APP from SystemProviders. (I3df00)
  • ObservableWatchData is now a sealed class. (Ic940d)
  • CanvasComplicationFactory.create (which is typically io bound) is now called on a background thread for each complication before ui thread rendering commences. There is a memory barrier between construction and rendering so no special threading primitives are required. (Ia18f2)
  • Watchface construction is now done on a background thread although all rendering is done on the ui thread, GlesRenderer supports two linked contexts to support this. WatchFaceControlClient.createHeadlessWatchFaceClient and WatchFaceControlClient.getOrCreateInteractiveWatchFaceClient may resolve before WatchFaceService.createWatchFace has completed. Subsequent API calls will block until watchFace initialization has completed. (Id9f41)
  • EXPANSION_DP and STROKE_WIDTH_DP are no longer visible in api.txt. (I54801)
  • We have made EditorSession.createOnWatchEditingSession throw TimeoutCancellationException if there's an error instead of sending a null session. Additionally, the return value of EditorRequest.createFromIntent and EditorSession.createOnWatchEditingSession is now NonNull. (I41eb4)

Version 1.0.0-alpha14

May 18, 2021

androidx.wear:wear-*:1.0.0-alpha14 is released. Version 1.0.0-alpha14 contains these commits.

New Features

  • EditorSession.openComplicationProviderChooser now returns ChosenComplicationProvider which contains the complication id, ComplicationProviderInfo and a Bundle containing any additional extras returned by the provider chooser.
  • In addition we have been steadily migrating code to Kotlin and the majority of the watch face API is now defined in Kotlin.

API Changes

  • GlesRenderer properties eglContext and eglDisplay are now non-nullable. Any GL errors are now reported via GlesRenderer.GlesException rather than via RuntimeExceptions. (Ib1005)
  • We have migrated androidx.wear.watchface.complications.rendering.ComplicationDrawable from Java to Kotlin (Ibc3eb)
  • We have migrated androidx.wear.watchface.complications.rendering.ComplicationStyle from Java to Kotlin (I3375e)
  • We added information about the complication provider for each complication within EditorSession. (I37f14)
  • We extended the result of EditorSession.openComplicationProviderChooser to include information returned by the chosen. (Iead6d)

Wear Complications & Watchface Version 1.0.0-alpha13

May 5, 2021

androidx.wear:wear-*:1.0.0-alpha13 is released. Version 1.0.0-alpha13 contains these commits.

New Features

  • Watch faces can have important visual elements beyond showing the time and complications. To provide screen reader support for this, watchface can now specify accessibility ContentDescriptionLabels via the Renderer's additionalContentDescriptionLabels property. In addition, to control the ordering of ContentDescriptionLabels accessibilityTraversalIndex has been added to complications. This can be modified by a ComplicationsUserStyleSetting.

  • To encourage developers to carefully consider screen readers we have made ShortTextComplicationData.Builder's, LongTextComplicationData.Builder's and RangedValueComplicationData.Builder's contentDescription field mandatory to be passed into their constructors. If ComplicationText.EMPTY is passed in for the contentDescription, a contentDescription will be automatically generated from the text and title.

  • WatchFaceControlClient.getOrCreateInteractiveWatchFaceClient now throws ServiceStartFailureException if the watchface throws an exception during init, this makes it much easier to diagnose issues during watch face startup.

API Changes

  • We added support for having a null component name in ComplicationProviderInfo, which is needed to support older versions of Wear OS. (I744d2)
  • We have migrated androidx.wear.complications.SystemProviders from Java to Kotlin. (Ia1f8b)
  • We have hidden all classes from public API that are in android.support.wearable.complications and created corresponding wrappers in AndroidX where needed. (I7bd50)
  • We have renamed method in TimeDifferenceComplicationText.Builder from setMinimumUnit to setMinimalTimeUnit. (I20c64)
  • We have made ShortTextComplicationData.Builder's, LongTextComplicationData.Builder's and RangedValueComplicationData.Builder's contentDescription field mandatory to be passed in constructor. (I8cb69)
  • We have renamed ComplicationProviderService.onComplicationUpdate to onComplicationRequest and encapsulated id and type parameter of this method into data ComplicationRequest. Corresponding listener has been renamed to ComplicationRequestListener and its method ComplicationRequestListener.onComplicationData. (Iaf146)
  • We have removed method isActiveAt from ComplicationData and exposed field validTimeRange instead of it. This method call can be replaced with validTimeRange.contains. (I65936)
  • We have changed description of the method ComplicationProviderService.onComplicationActivated to receive a ComplicationType instead of an int. (Idb5ff)
  • Migrated ProviderUpdateRequester from Java to Koltin. (Ibce13)
  • GlesRender.makeContextCurrent is now public. Watch face code may need to make gl calls outside of render and onGlContextCreated and because there may be both an interactive and a headless context its necessary to call this. (I8a43c)
  • WatchFaceControlClient.getOrCreateInteractiveWatchFaceClient now throws ServiceStartFailureException if the watchface throws during init. In addition WatchFaceService now throws an exception if createWatchFace takes longer than 6 seconds. (I59b2f)
  • We have removed the unused id property of GlesTextureComplication. (I28958)
  • The watchface can now specify accessibility ContentDescriptionLabels via the Renderer's additionalContentDescriptionLabels property. In addition to controlling the ordering of ContentDescriptionLabels accessibilityTraversalIndex has been added to complications. This can be modified by a ComplicationsUserStyleSetting. (Ib7362)
  • Expand documentation about touch event handling in the watch face. (Iaf31e)

Bug Fixes

  • EditorSession.getComplicationsPreviewData() now returns a map for every rather only non-empty complications. An instance of EmptyComplicationData is used for empty complications. (I1ef7e)

Wear Complications & Watchface Version 1.0.0-alpha12

April 21, 2021

androidx.wear:wear-*:1.0.0-alpha12 is released. Version 1.0.0-alpha12 contains these commits.

New Features

Watch face editors need to highlight parts of the watch face to help convery which aspect of a watch is being configured. We’ve extended RenderParameters to allow styles as well as complications to be highlighted. There’s a new optional HighlightLayer which is intended to be matted on top of the watch face with alpha transparency (the screenshot apis can do this matting for you, or provide the HighlightLayer on its own for maximum flexibility). E.g. suppose you had a style that lets you configure the appearance of the watch hands, your renderer in its renderHighlightLayer can draw an outline around them.

To encourage Complication Provider support for accessibility we have made PhotoImageComplicationData.Builder's, MonochromaticImageComplicationData.Builder's and SmallImageComplicationData.Builder's contentDescription field to be a mandatory constructor argument. ComplicationTapFilter and Complication.createEdgeComplicationBuilder have been added to support edge complications (drawn around the edge of the screen). Rendering and hit testing of edge complications is left up to the watch face. Edge hit testing isn't supported from the companion editor.

API Changes

  • Added PROVIDER_ prefix to constants in SystemProviders. (I1e773)
  • We have made PhotoImageComplicationData.Builder's, MonochromaticImageComplicationData.Builder's and SmallImageComplicationData.Builder's contentDescription field mandatory to be passed in constructor. (I9643a)
  • ProviderInfoRetriever.requestPreviewComplicationData has been renamed to retrievePreviewComplicationData. (I911ee)
  • Migrated ComplicationProviderService from Java to Koltin. (I849f2)
  • Method ComplicationProviderService.onBind is now final (I39af5)
  • We've reinstated interface CanvasComplication and moved CanvasComplicaitonDrawable, GlesTextureComplication and ComplicationHighlightRenderer to wear-watchface-complications-rendering. (I84670)
  • RenderParameters has been refactored to support extended highlight rendering. It's now possible to request rendering of highlights for styles as well as all or a single complication. In addition CanvasRenderer and GlesRenderer how have a new abstract renderHighlightLayer method for rendering any highlighting requested by the editor. Layer has been renamed to WatchFaceLayer. (Ic2444)
  • ComplicationTapFilter and Complication.createEdgeComplicationBuilder have been added to support edge complications. Rendering and hit testing of edge complications is left up to the watch face. Hit testing isn't supported from within editors. (Ia6604)
  • For DoubleRangeUserStyleSetting & LongRangeUserStyleSetting: defaultValue, maximumValue and minimumValue are now kotlin properties. In addition, UserStyleSetting.Option functions like toBooleanOption, toCoplicationOptions, toListOption and similar have been removed. (I52899)
  • Add chin size to the properties of the device available to the watch face. (I76e1e)
  • ComplicationHighlightRenderer's constructor now accepts outlineExpansion and outlineStrokeWidth parameters. (I87009)
  • ComplicationDrawable.getNoDataText is now part of the public API. (I00598)

April 7, 2021

androidx.wear:wear-*:1.0.0-alpha11 is released. Version 1.0.0-alpha11 contains these commits.

New Features

  • More polish has been applied to the watch face APIs. Most of the changes are simple renamings but InteractiveWatchFaceWcsClient and InteractiveWatchFaceSysUiClient have been merged into InteractiveWatchFaceClient.

API Changes

  • ContentDescriptionLabel.text is now a ComplicationText rather than the old wearable support library TimeDependentText. (I80c03)
  • SystemProviders.GOOGLE_PAY is not guaranteed to be present on all Android R devices so it has been removed from the list. It's still possible to use this provider via DefaultComplicationProviderPolicy (If01b5)
  • We've renamed ComplicationUpdateCallback to ComplicationUpdateListener for consistency. (I61ec7)
  • The UserStyle wire format map has been changed to Map<String, byte[]> and for convenience a UserStyleData class has been added to the public API and is now used by wear-watchface-client and wear-watchface-editor. In addition CustomValueUserStyleSetting.CustomValueOption.value is now byte[] instead of String. (Iaa103)
  • UserStyleSetting and UserStyleSetting.Option now use UserStyleSetting.Id and UserStyleSetting.Option.Id respectively to store their ids rather than a String. (I63f72)
  • InteractiveWatchFaceClient.SystemState has been renamed to WatchUiState. (I6a4e0)
  • InteractiveWatchFaceWcsClient and InteractiveWatchFaceSysUiClient have been merged because it was hard to explain the division of responsibility (Iff3fa)
  • Layer enum values have been renamed for clarity. Layer#TOP_LAYER is now Layer#COMPLICATIONS_OVERLAY and Layer#BASE_LAYER is now Layer#BASE (Ia144e)
  • UserStyleListener has been renamed to UserStyleChangeListener (I18524)
  • UserStyleRepository has been renamed to CurrentUserStyleRepository (I6ea53)
  • InteractiveWatchFaceWcsClient.updateInstance has been renamed to updateWatchfaceInstance. (I321dc)
  • WatchFace TapType events have been renamed to align with MotionEvents / Compose. (I0dfd0)
  • takeWatchfaceScreenshot has been renamed to renderWatchFaceToBitmap, and takeComplicationScreenshot has been renamed to renderComplicationToBitmap (Ie0697)
  • The CanvasComplication interface has been removed in favor of the open class CanvasComplicationDrawable. (I1f81f)
  • WatcfaceControlServiceFactory has been removed from the public api. (I1f8d3)
  • We've renamed CanvasComplication.setData to CanvasComplication.loadData. (If1239)
  • ComplicationsManager.bringAttentionToComplication has been renamed to displayPressedAnimation. (Ic4297)
  • WatchFaceService.createWatchFace now has an @UiThread annotation. (Ib54c2)
  • Changed the name of a CanvasComplicationDrawable parameter to fix a bug. (I50dac)
  • We've added HeadlessWatchFaceClient.toBundle() and HeadlessWatchFaceClient.createFromBundle to support sending HeadlessWatchFaceClient over AIDL. (I07c35)
  • HeadlessWatchFaceClient and InteractiveWatchFaceClient now have ClientDisconnectListener and isConnectionAlive() to allow you to observe if the connection is broken for some reason (e.g. the watchface being killed). (Ie446d)
  • WatchFaceControlClient#getOrCreateWallpaperServiceBackedInteractiveWatchFaceWcsClientAsync is now a suspend function and has been renamed to getOrCreateInteractiveWatchFaceClient. (Ib745d)
  • EditorState.commitChanges and hasCommitChanges() has been renamed to shouldCommitChanges(). (I06e04)
  • previewComplicationData has been renamed to previewComplicationsData to indicate theres (usually) more than one complication in the map. (I56c06)
  • InteractiveWatchFaceWcsClient.bringAttentionToComplication has been renamed to displayPressedAnimation for consistency with ComplicationsManager.displayPressedAnimation. (Ic9999)
  • All instances of watchface instance id have been encapsulated in a new WatchFaceId class (I45fdf)
  • complicationState property has been renamed to complicationsState to indicate plurality. (Ided07)
  • We've removed the various wear-watchface-client Binder conversions, they should be necessary. (Icc4c0)
  • For consistency EditorServiceClient has been refactored to use listeners instead of observers. (Iec3a4)
  • We've added a couple of missing @Px annotations to InteractiveWatchFaceSysUiClient and WatchFaceControlClient. (I3277a)
  • Renamed EditorObserverCallback to EditorObserverListener for consistency. (Ie572d)
  • EditorState.watchFaceInstanceId is restricted to Android R API level and above and is no longer nullable. (Id52bb)
  • EditorSession.launchComplicationProviderChooser has been renamed to openComplicationProviderChooser. (I9d441)
  • EditorSession.createOnWatchEditingSessionAsync has been renamed to createOnWatchEditingSession and is now a suspend function. (Id257b)
  • Added several missing @UiThread annotations on EditorSession. (I6935c)
  • UserStyleSetting.affectsLayers has been renamed to affectedLayers. (I6e22b)

Version 1.0.0-alpha10

March 24, 2021

androidx.wear:wear-*:1.0.0-alpha10 is released. Version 1.0.0-alpha10 contains these commits.

New Features

  • It’s now possible to create open gl objects (e.g. textures) during WatchFaceService.createWatchFace because GlesRenderer now requires an explicit call to initOpenGLContext which can be done inside createWatchFace.

API Changes

  • IdAndComplicationData was a bit awkward and has been removed from the public API. Classes & interfaces that used it have been refactored. (I4c928)
  • We've replaced ReferenceTime with CountUpTimeReference and CountDownTimeReference which are more self explanatory. (Ib66c6)
  • Added some missing @Px and @ColorInt annotations. (I9bbc3)
  • Complication.complicationConfigExtras is now non-nullable and defaults to Bundle.EMPTY. (Iad04f)
  • GlesRenderer now requires you to call initOpenGLContext after construction. This function was an internal detail but is now on the public API to allow GL calls earlier inside createWatchFace. (I726c2)
  • We've removed Complication.setRenderer as it should not be needed. (Ie992f)
  • Complicaiton.setComplicationBounds is no longer part of the public API. If you need to adjust the position of a complication, this can be done via ComplicationsUserStyleSetting. (Ibd9e5)
  • ComplicationsManager.TapCallback.onComplicationSingleTapped has been renamed to onComplicationTapped. (I3a55c)
  • ComplicationOutlineRenderer.drawComplicationSelectOutline has been renamed to drawComplicationOutline. (I14b88)

Version 1.0.0-alpha09

March 10, 2021

androidx.wear:wear-complications-*:1.0.0-alpha09 and androidx.wear:wear-watchface-*:1.0.0-alpha09 are released. Version 1.0.0-alpha09 contains these commits.

New Features

  • The interface between WCS/SysUI host and the on watch face has evolved. It’s now possible for an editor to determine if a style change will enable or disable a complication (enabled = initiallyEnabled plus any override from ComplicationsUserStyleSetting). Also EditorService.closeEditorallows SysUI to remotely close an on watch face editor if needed.
  • In addition InteractiveWatchFaceWcsClient.setUserStyle with a more powerful command updateInstance which: changes the instance ID, sets the style, and clears complications all in one go.

API Changes

  • TraceEvents have been added to the watchface libraries. (I1a141)
  • ComplicationState now has a new property initiallyEnabled which is useful for predicting the consequences of switching styles. (I8c905)
  • We've replaced InteractiveWatchFaceWcsClient.setUserStyle with a more powerful command updateInstance which: changes the instance ID, sets the style, and clears complications. (Ife6f6)
  • WatchFaceClient screenshot APIs no longer compress the screenshots because that was slow, instead we leave any post processing up to the caller. (Id35af)
  • It's now possible to remotely close an on watchface editor via EditorService.closeEditor. (Ic5aa4)
  • Added nullability annotations (Ic16ed)

Version 1.0.0-alpha08

February 24, 2021

androidx.wear:wear-*:1.0.0-alpha08 is released. Version 1.0.0-alpha08 contains these commits.

New Features

  • Some watch faces are designed around one or more specific complications, to support this we’ve added Complication.Builder#setFixedComplicationProvider which if set to true prevents the user from changing the complication in that slot.
  • The watchface libraries are Kotlin first and use coroutines (e.g. suspend functions). For Java users we’ve provided ListenableFuture wrappers to improve interoperability in the following libraries: wear/wear-watchface-guava, wear/wear-watchface-client-guava & wear/wear-watchface-editor-guava.

API Changes

  • We've removed support for double taps on complications launching the provider chooser, this feature wasn't common in watchfaces and complicated the implementation of SysUI. (I3ef24)
  • ProviderInfoRetriever methods may throw ServiceDisconnectedException if the binder closes unexpectedly. (Ib2cc4)
  • From Android 11 onwards, there are restrictions on when the ProviderChooser can be run, in addition we'd like editors to be built with the new wear-watchface-editor so ComplicationHelperActivity is being removed from the public API. (Ib19c1)
  • Remove ComplicationText static methods in favor of builders. (Ibe399)
  • We have introduced guava ListenableFuture wrappers for the various watch face library suspended methods. (I16b2c)
  • For API clarity we've added a secondary constructor to RenderParameters which doesn't require a tint, for use with LayerModes other than LayerMode.DRAW_OUTLINED. (I497ea)
  • Previously ListUserStyleSetting was different from the other because it had a default argument. Now all the StyleSetting subclass constructors take the default value last. (I9dbfd)
  • CanvasComplication has been refactored to use have a hidden method, which makes it easier to implement a subclass (I5b321)
  • We have refactored away EditorResult in favor of a new EditorService and EditorSession.broadcastState() to stream updates to an observer (typically SysUI). (Ic4370)
  • Some watchfaces are built around a particular complication as an integral part of the watch face where the provider is not user configurable. To support this we've added Complication.Builder#setFixedComplicationProvider. (I4509e)
  • EditorRequest now specifies package name rather than ComponentName because it was inconvenient for SysUI to look up the class name of the editor, and we only really need the package name. (Ib6814)

Version 1.0.0-alpha07

February 10, 2021

androidx.wear:wear-*:1.0.0-alpha07 is released. Version 1.0.0-alpha07 contains these commits.

New Features

  • WatchFaceService.createWatchFace is now a suspend function which means the watchface no longer has to block the ui thread while waiting for IO. Similarly wear-watchface-editor and wear-complications-data

API Changes

  • Remove PhotoImage class and use Icon directly. (I8a70b)
  • Expose the validTimeRange of ComplicationData. (I91366)
  • Make image-like attributes more explicit. (I81700)
  • wear-watchface-editor and wear-complications-data have been refactored to use suspend functions instead of coroutines. Rx java & Future compat wrappers to follow. (If3c5f)
  • ProviderInfoRetriever now now throws PreviewNotAvailableException if requestPreviewComplicationData can't return preview data due to connection issues or lack of API support. (I4964d)
  • WatchFaceControlService::createWatchFaceControlClient is now a suspended fuction and getOrCreateWallpaperServiceBackedInteractiveWatchFaceWcsClient is now called getOrCreateWallpaperServiceBackedInteractiveWatchFaceWcsClientAsync returning Deferred<InteractiveWatchFaceWcsClient>. RX java and Future compat wrappers to follow. (I5d461)
  • Rename CATEGORY_PROVIDER_CONFIG_ACTION to CATEGORY_PROVIDER_CONFIG. (I7c068)
  • Please note createOnWatchEditingSession is now a suspended function because the watchface sometimes isn't available until shortly after the editor activity has started. (Ida9aa)
  • WatchFaceService.createWatchFace is now a suspend function which allows for async initialization, previously you would have had to block the main thread. (If076a)
  • UserStyle now has an array operator and we've added casting helpers to UserStyle.Option. (I35036)
  • We've fixed a marshalling bug with UserStyle wireformats changing some of the unstable hidden API. (I8be09)
  • We've added CustomValueUserStyleSetting which lets you store a single application specific string within a UserStyle. The default watch face editors will ignore this value. (Ic04d2)
  • InstanceID is not passed in the intent extras for R and older versions of Android WearOS which we can't upgrade. To support this we now allow InstancID to be null. (Id8b78)
  • EditorRequest now includes the editor ComponentName which is set as the component in WatchFaceEditorContract.createIntent (I3cd06)
  • The watchface EditorResult now includes preview ComplicationData to allow the caller to take a screenshot of the watchface after editing. (I2c561)

Bug Fixes

  • Added toString() overrides to UserStyle, UserStyleSetting and UserStyleSchema which makes working with these classes a bit nicer. (I9f5ec)

Version 1.0.0-alpha06

January 27, 2021

androidx.wear:wear-*:1.0.0-alpha06 is released. Version 1.0.0-alpha06 contains these commits.

New Features

  • We’ve introduced a new library wear/wear-watchface-editor which allows watch face developers and potentially OEMs to build a style and complication editor. SysUI will send an Intent to the watch face which will use the new EditorSession class to access WatchFace details and record the result via Activity.setWatchRequestResult. To support this we’ve added ProviderInfoRetriever.requestPreviewComplicationData which allows watch face editors to request preview ComplicationData. The advantage of preview ComplicationData is unlike live data you don’t have to worry about showing permission dialogs when rendering your editor (note if a user selects a provider with a permission they will still be prompted to grant the permission).

API Changes

  • ComplicationProviderInfo now has a field for the provider's ComponentName, support for this field will be added to WearOS at a later date and in the meantime, it will be null. (Id8fc4)
  • We've added ProviderInfoRetriever.requestPreviewComplicationData which allows watch face editors to request preview ComplicationData. This is useful because live complications may require permissions and you can now display preview data for complications that are not active. (I2e1df)
  • ComplicationManager is now an optional parameter of WatchFace constructor and the arguments have been reordered to allow this. (I66c76)
  • We've added an optional Bundle to Complications which if set gets merged in with the intent sent to launch the provider chooser activity. (Ifd4ad)
  • We've added a new wear-watchface-editor library to support on watch face and SysUi hosted editors. SysUI will launch these editors by sending an intent. The watch face activity service can use the new EditorSession class to access WatchFace details and record the result via Activity.setWatchRequestResult. (I2110d)
  • LayerMode.DRAW_HIGHLIGHTED is now called LayerMode.DRAW_OUTLINED and RenderParameters.highlightComplicationId is now called RenderParameters.selectedComplicationId which draws a highlight on the specified complication in addition to an outline. (I90a40)
  • WatchFaceControlClient.getOrCreateWallpaperServiceBackedInteractiveWatchFaceWcsClient's future can now resolve with a ServiceStartFailureException if the service dies while waiting for the watchface to be created. (I0f509)
  • EditorSession.complicationPreviewData is now a ListenableFuture because fetching this data is an asynchronous process. (Iead9d)

Bug Fixes

  • We're removing unused fields from ComplicationOverlay leaving enabled and complicationBounds. (I17b71)

Version 1.0.0-alpha05

January 13, 2021

androidx.wear:wear-*:1.0.0-alpha05 is released. Version 1.0.0-alpha05 contains these commits.

New Features

Watchfaces often support a number of complication configurations with varying numbers of complications shown. To make this easier to set up we now support initially disabled complications by calling setEnabled(false) on the builder. These can be enabled later via ComplicationsUserStyleSetting.

API Changes

  • ComplicationHelperActivity now accepts Collection<ComplicationType> rather than an int array making it easier to use. (I1f13d)
  • ProviderInfoRetriever.retrieveProviderInfo now correctly returns ListenableFuture<ProviderInfo[]>. (If2710)
  • You can now create an initially disabled complication by calling setEnabled(false) on the builder. (Idaa53)
  • WatchFaceState now has an isHeadless property which is only true for headless instances. (Ifa900)
  • ComplicationDrawable now optionally supports synchronous loading of drawables. This is used by the screenshot APIs. (I34d4a)

Version 1.0.0-alpha04

December 16, 2020

androidx.wear:wear-*:1.0.0-alpha04 is released. Version 1.0.0-alpha04 contains these commits.

New Features

  • The wear watch face library now supports setting bounds per type. E.g. you can switch to a wide bounding box for ComplicationType.LONG_TEXT whilst using a smaller bounding box for other types.

API Changes

  • Complications now use ComplicationBounds which wraps a Map<ComplicationType, RectF> to support per complication type sizes. (I1ebe7)
  • RenderParameters now lets you specify the highlight tint for use in screen shots. (Iff42b)
  • With the exception of bounds you now have to use ComplicationsUserStyleSetting to modify complications, this is to ensure the OS is kept in sync. (I8dc5d)
  • Renderer is now a sealed class. This means CanvasRenderer and GlesRenderer are now inner classes of Renderer. (Iab5d4, b/173803230)
  • CanvasComplicationDrawable.drawHighlight renamed to drawOutline. ObservableWatchData now has a few missing UiThread annotations. ScreenState has now been fully removed from WatchState. (If1393)
  • The minimum API level for wear-watchface is now 25. Note hardware canvas support requires API level 26 or above. (Ic9bbd)
  • InteractiveWatchFaceWcsClient now has a getComplicationIdAt helper. (I05811)
  • The API level for wear-watchface-client has been reduced to 25, however the screen shot APIs require API level 27. (Id31c2)

Bug Fixes

  • We now expose the complication's current ComplicationData's ComplicationType in ComplicationState. (I9b390)
  • InteractiveWatchFaceWcs now has a method `bringAttentionToComplication to briefly highlight the specified complication. (I6d31c)
  • InteractiveWatchFaceWcsClient#setUserStyle now has an overload accepting Map which can potentially avoid an extra IPC round trip necessary to construct UserStyle. (I24eec)

Version 1.0.0-alpha03

December 2, 2020

androidx.wear:wear-*:1.0.0-alpha03 is released. Version 1.0.0-alpha03 contains these commits.

New Features

The Complication class now has a compicationData property letting watch faces observe ComplicationData changes. This makes it possible to change the complication’s dimensions based on the type of the complication.

Variable frame rates are now supported by assigning to Renderer.interactiveDrawModeUpdateDelayMillis. For watch faces which run short animations every second this can lead to good power savings by going to sleep when not animating.

API Changes

  • BACKGROUND_IMAGE has been renamed to PHOTO_IMAGE along with related classes. This type of complication is not exclusively used for backgrounds hence the name change. (I995c6)
  • DefaultComplicationProviderPolicy properly annotated with IntDefs. (I3b431)
  • The hidden TimeDependentText class is no longer exposed via ContentDescriptionLabel, instead we add an accessor to get the text at a specified time. (Ica692)
  • ObservableWatchData's constructor is now internal. (I30121, b/173802666)
  • Complication now has compicationData letting watch faces observe ComplicationData changes. Complication also has a new isActiveAt call which can be used to tell if anything should be rendered at the provided datetime. (Ic0e2a)
  • The empty SharedMemoryImage is no longer in the public API. (I7ee17)
  • WatchFace.overridePreviewReferenceTimeMillis now has an IntRange annotation and the getter and setter have consistent names. (Ia5f78)
  • Complication.Builder is now created via Complication.createRoundRectComplicationBuilder or Complication.createBackgroundComplicationBuilder for clarity (I54063)
  • Added WatchFace.TapListener which allows taps not consumed by complications to be observed by the WatchFace. (Ic2fe1, b/172721168)
  • WatchFace now supports variable frame rates by assigning to Renderer.interactiveDrawModeUpdateDelayMillis. This can help preserve battery life by sleeping when not animating. (I707c9)
  • WatchFace.Builder is no longer needed and invalidate() and interactiveUpdateRateMillis have been moved to Renderer. (I329ea)
  • For better java interoperability renamed getters for boolean properties in WatchState (I6d2f1)
  • Renamed TapListener to TapCallback and InvalidateCallback to InvalidateListener for consistency. (I9414e)
  • Wear 2.0 watchface style options have been moved to their own class for clarity. WatchFace.Builder setters now have symmetrical WatchFace class getters. (Iefdfc)
  • Added InteractiveWatchFaceWcsClient and WatchFaceControlClient.getOrCreateWallpaperServiceBackedInteractiveWatchFaceWcsClient which either gets an existing instance or creates it once the wallaper service has connected and made the engine. (Id666e)
  • WatchFaceControlClient is now an interface to allow tests to mock it. (I875d9)
  • HeadlessWatchFaceClient, InteractiveWatchFaceSysUiClientImpl, InteractiveWatchFaceWcsClient are now interfaces to better facilitate testing. (I7cdc3)
  • Added annotations to methods in wear-watchface-complications-rendering (I0d65c)

Bug Fixes

  • Remove screen shape from DeviceConfig, which was duplicating android.content.res.Configuration#isScreenRound() (Ifadf4)
  • Changed WatchFaceControlClient.getOrCreateWallpaperServiceBackedInteractiveWatchFaceWcsClient to accept a Map<String, String> instead of UserStyle because it's hard to create a UserStyle without knowing the schema which you can only get after the client has been created. (Iea02a)
  • Fix InteractiveWatchFaceWcsClient to use ComplicationState instead of the wire format. (Icb8a4)
  • UserStyleSettings is now a sealed class because the watch face editors only understand the built in classes. (I2d797)

Version 1.0.0-alpha02

November 11, 2020

androidx.wear:wear-*:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

API Changes

  • ComplicationDetails is now called ComplicationState and is properly wrapped and usages of wearable support @ComplicationData.ComplicationType have been migrated to androidx ComplicationType. (I4dd36)
  • Add an optional highlightedComplicationId parameter to RenderParameters which allows you to request highlighting of a single complication in screenshots. (I66ce9)
  • ComplicationProviderService to use new style complication api for consistency (Id5aea)
  • getPreviewReferenceTimeMillis now gets reference times from DeviceConfig. (I779fe)
  • Simplifying Renderer API surface, can use SurfaceHolder.Callback to observe changes instead. (I210db)
  • CanvasComplicationRenderer doesn't extend from Renderer, renaming it for clarity. (Ibe880)

Bug Fixes

  • First version of androidx.wear:wear-watchface-client (I1e35e)
  • Changed the name of GlesTextureComplication#renderer for clarity (Ib78f7)
  • Rename StyleCategory to StyleSetting for clarity (I488c7)

  • Create androidx.wear:wear-complications-provider library. (I77f1f)
  • ComplicationsUserStyleCategory the new recommended category for configuring complications (I96909)
  • Add wear-complication-data API. (I7c268)
  • Functions with boolean return values to be prefixed with “is” rather than “get” (If36ff)
  • API advice is to avoid using protected so this class has been refactored to take parameters in via the constructor. (I61644)
  • Rename setBackgroundComplication for clarity. (I96fe3)
  • Use Kotlin properties for ComplicationDrawable isHighlighted & data (I4dcc8)
  • Instead of ComplicationRenderer.InvalidateCallback we add Complication#invalidate() (I4f4c6)
  • These APIs are being deprecated in WearableSupport and are removed here. (Ib425c)

androidx.wear:wear:1.2.0 is released. Version 1.2.0 contains these commits.

Important changes since 1.1.0

  • Added CurvedText component for easily writing curved text following the curvature of the largest circle that can be inscribed in the view. An usage example:

    <androidx.wear.widget.CurvedText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="example curved text"
            app:anchorAngleDegrees="180"
            app:anchorPosition="center"
            app:clockwise="false"
            style="@android:style/TextAppearance.Large"
    />
    

    An example of curved text in Android Wear

  • Added ArcLayout container for laying out its child elements one by one on an arc in either the clockwise or counterclockwise direction. Its children can be both standard android widget or "curved" widgets which implement the ArcLayout.Widget interface. (I536da) An usage example:

    <androidx.wear.widget.ArcLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:anchorPosition="center">
          <ImageView
                  android:layout_width="20dp"
                  android:layout_height="20dp"
                  android:src="@drawable/ic_launcher"
          />
          <androidx.wear.widget.CurvedText
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:text="Curved Text"
                  style="@android:style/TextAppearance.Small"
                  android:padding="2dp"
           />
      </androidx.wear.widget.WearArcLayout>
    

    An example of arch text in Android Wear

  • Added a new layout container, DismissibleFrameLayout, which handles back-button-dismiss and/or swipe-to-dismiss, intended for use within an activity. At least one listener must be added to act on a dismissal action. A listener will typically remove a containing view or a fragment from the current activity. setSwipeDismissible(boolean) & setBackButtonDismissible(boolean) are provided for direct control over the features. This new layout is meant to replace the existing SwipeDismissFrameLayout.

  • Added support for indicating that an Activity can be “auto-resumed” when the device leaves ambient mode in the AmbientModeSupport class. This functionality was previously available in the deprecated WearableActivity class from WearableSupportLibrary. (I336ab)

  • Migrated WearableCalendarContract class from Wearable Support Library. This API provides a subset of the data available through CalendarContract, but is automatically synced to wearable devices. (I6f2d7)

  • Added a new API WearTypeHelper in androidx.wear.utils for determining whether the given wear device is for China. (Ib01a9)

  • Added accessibility features to androidx.wear.widget.ConfirmationOverlay that will read out messages if set followed by animation description. (I524dd)

  • Fixed bug that caused ConfirmationActivity to crash if no message was provided. (Ie6055)

  • Fixed bug where horizontally scrolling RecyclerViews caused WearableDrawerLayout to peek on all interactions. (I24c7f)

Version 1.2.0-alpha06

January 27, 2021

androidx.wear:wear:1.2.0-alpha06 is released. Version 1.2.0-alpha06 contains these commits.

API Changes

  • Migrate the Ongoing Activities library to a new sub-library: wear-ongoing. Classes now live in the androidx.wear.ongoing package (previously was androidx.wear.ongoingactivities) (I7c029)
  • Migrate WearableCalendarContract class from Wearable Support Library to AndroidX. This API provides a subset of the data available through CalendarContract, but is automatically synced to wearable devices. (I6f2d7)

API Changes

  • Added support for indicating that an Activity can be “auto-resumed” when the device leaves ambient mode in the AmbientModeSupport class. This functionality was previously available in the deprecated WearableActivity class from WearableSupportLibrary. (I336ab)
  • OngoingActivity
    • Category can now be set when creating an OngoingActivity, e.g. OngoingActivitiy.Builder.getCategory(String)
    • OngoingActivityData now has a timestamp of when the OngoingActivity was built - OngoingActivityData.getTimestamp()
    • (I91cb4)
  • Added support for setting margins on children of WearArcLayout by changing the layout params to extend MarginLayoutParams, i.e. WearArcLayout.LayoutParams extends android.view.ViewGroup.MarginLayoutParams. (I2cd88)
  • Change WearCurvedTextView's anchor type default to WearArcLayout.ANCHOR_CENTER (was WearArcLayout.ANCHOR_START). This simplifies the contract between the arc layout and the curved text as the curved text by default draws itself x-centered at the top, and the parent arc layout can rotate it to where it needs to be. (I105ff)

Version 1.2.0-alpha03

December 2, 2020

androidx.wear:wear:1.2.0-alpha03 is released. Version 1.2.0-alpha03 contains these commits.

New Features

A new layout container DismissibleFrameLayout, which handles back-button-dismiss and/or swipe-to-dismiss, intended for use within an activity. At least one listener must be added to act on a dismissal action. A listener will typically remove a containing view or a fragment from the current activity. setSwipeDismissible(boolean) & setBackButtonDismissible(boolean) are provided for direct control over the features. This new layout is meant to replace the existing SwipeDismissFrameLayout.

Curved widgets now handle touch events. Normal widgets inside an WearArcLayout will receive all touch events, mapped to their coordinate space. WearCurvedTextView (inside an WearArcLayout or not) can set onClick and onLongClick handlers.

Ongoing activities classes are now VersionedParcelables instead of using custom serialization/deserialization. The static icon and touch intent are now required.

API Changes

  • The attribute "sweepDegrees" for WearCurvedTextView is separated into minSweepDegrees and maxSweepDegrees to give a more flexible layout of this widget.

Version 1.2.0-alpha02

November 11, 2020

androidx.wear:wear:1.2.0-alpha02 is released. Version 1.2.0-alpha02 contains these commits.

This release adds a new “Ongoing Activities API” for the first time. This API can be used by developers to signal that a long running activity, such as a fitness exercise or a media playback session is on-going. It allows developers to provide periodic status updates such as “distance and time run” or “current track playing” for display on the watch face or in the app launcher. This functionality is targeted at future devices with the on-going activity functionality enabled.

API Changes

  • New API for Ongoing Activities, this is a no-op on "unsupported devices.". (I69a31)

Version 1.2.0-alpha01

October 28, 2020

androidx.wear:wear:1.2.0-alpha01 is released. Version 1.2.0-alpha01 contains these commits.

New Features

  • Added WearCurvedTextView component for easily writing curved text following the curvature of the largest circle that can be inscribed in the view. An usage example:
<androidx.wear.widget.WearCurvedTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="example curved text"
        app:anchorAngleDegrees="180"
        app:anchorPosition="center"
        app:clockwise="false"
        style="@android:style/TextAppearance.Large"
/>

An example of curved text in Android Wear

  • Added WearArcLayout container for laying out its child elements one by one on an arc in either the clockwise or counterclockwise direction. Its children can be both standard android widget or "curved" widgets which implement its ArcLayoutWidget interface. An usage example:
<androidx.wear.widget.WearArcLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:anchorPosition="center">
      <ImageView
              android:layout_width="20dp"
              android:layout_height="20dp"
              android:src="@drawable/ic_launcher"
      />
      <androidx.wear.widget.WearCurvedTextView
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:text="Curved Text"
              style="@android:style/TextAppearance.Small"
              android:padding="2dp"
       />
  </androidx.wear.widget.WearArcLayout>
