API Changes

• Several improvements to PositionIndicator: ShowResult renamed PositionIndicatorVisibility. Some performance improvements to avoid recomputations when not needed (Iaed9d)
• The recommended coloring for the SplitToggleChip has been updated. SplitToggleChip's now have a solid colored background when checked or unchecked with the coloring of the ToggleControl being the primary indication of whether the component is checked or not. We have added a new ToggleDefaults.splitToggleChipColors() to support the new color scheme. We have also simplified the toggleChipColors() methods removing the splitBackgroundOverlayColor (I7e66e)
• We have added unadjustedSize to the ScalingLazyListItemInfo as it is not safe to calculate the original item size using the scaled size and scaling factor due to float maths precision. (I54657, b/221079441)
• Add HorizontalPageIndicator. It represents a total number of pages and a selected page. Might be linear or curved, depending on the shape of the device. It also supports custom indicator shape, which defines how each indicator is visually represented. (Iac898)
• We have updated PickerState so that the numberOfOptions can be updated. This supports use-cases such as a DatePicker, when the number of days in the month changes depending on the month selected. The constructor parameter for PickerState has changed to initialNumberOfOptions accordingly. (Iad066)
• Hide the PositionIndicator when is a scrollbar and can't scroll. (Id0a7f)
• For consistency with Scaffold, our full-screen Dialog component now displays a PositionIndicator and a Vignette. We are also now using ScalingLazyColumn instead of Column, which means that the Dialog contents are now in ScalingLazyListScope (and typically need to be enclosed by item { /* content */ }). Dialog supports the verticalArrangement parameter accordingly. (Idea13)
• We have changed the name of ToggleChip and SplitToggleChip toggleIcon property to toggleControl to better align with Material Design in order to help designers and developers navigate the API. (If5921, b/220129803)
• We have added a new entry caption3 to the Wear Material Theme Typology.Caption3 is a small font used for the extra long-form writing like legal texts. (I74b13, b/220128356)

Bug Fixes

• Stop the snapping animation when we are there. (Idb69d)
• Animate changes in PositionIndicator. (I94cb9)
• Based on UI/UX feedback we have changed the ScalingLazyColumn autoCentering so that it will provide only enough space to make sure the items with index ScalingLazyListState.initialCenterItemIndex or higher will be able to be fully scrolled to the center of the viewport. This allows developers to place one or two items about the item initially in the center which are not scrollable into the middle. This will mean that an autoCenter'ing ScalingLazyColumn will not be able to scroll above the initialCenterItemIndex/initialCenterItemScrollOffset (I22ee2)
• We have added a demo for a Date Picker and fixed a bug in PickerState where the initiallySelectedOption was not applied until the Picker had been displayed. (Id0d7e)
• In order to reduce the clipping of wider ScalingLazyColumn items on circular screens we have increased the default horizontal content padding from 8 to 10 dp. (I0d609)
• Ensure the PositionIndicator is shown when scrolling. (Ied9a2)

Wear Watchface: v1.1.0-alpha04

March 9, 2022

androidx.wear.watchface:watchface-*:1.1.0-alpha04 is released. Version 1.1.0-alpha04 contains these commits.

API Changes

• Up to date ComplicationData may not always be available (e.g. expired cached ComplicationData) so we've extended NoDataComplication with an optional placeholder ComplicationData and added ComplicationText.PLACEHOLDER, MonochromaticImage.PLACEHOLDER, SmallImage.PLACEHOLDER, PhotoImage.PLACEHOLDER which are only allowed to be used inside the context of a NoDataComplicationData placeholder. If selected these placeholders are suggested to be rendered with gray boxes/arcs. (I6285d)
• We've added ComplicationData.getNextChangeInstant which tells you the next Instant after the reference Instant at which any field of the complication may change. This is used internally to schedule frames for complication updates. E.g. if a watch face normally updates once per minute, setting the stop watch complication will cause it to update once per second. (I7ceb2)
• EditorSession.watchFaceId can now be used on all API levels. In addition its value will now always be consistent with WatchState.watchFaceInstanceId. (I323b9)
• The getPendingIntentForTouchEvent API is no longer necessary since the underlying issue has been fixed in the framework, so all the related APIs have been removed. Watchfaces do not need to do anything special for PendingIntents to fire, even if the home button has recently been pressed. (I1f2e8)
• We've added RendererParameters.isForScreenShot which will be true if the render is for a screen shot. Some watch faces with animations need to know this in order to make adjustments to ensure the best results. (I96d99)
• We've added WatchFaceExceptionReason to WatchFaceException to give some context to what went wrong. (I01d15)
• ComplicationDataSourceService.onImmediateComplicationRequest has been removed, instead ComplicationRequest.immediateResponseRequired has been added to signal that the provider needs to respond quickly (ideally responding in < 100ms). Note this functionality is guarded behind the privileged com.google.android.wearable.permission.USE_IMMEDIATE_COMPLICATION_UPDATE permission. (Ie6b23)
• Updated nullability in core and appcompat to match Tiramisu DP2 (I0cbb7)

Bug Fixes

• Now watchface app crashes with an exception if the schema validation fails (Ia400f)
