Benchmark: v1.2.0-alpha08

December 7, 2022

androidx.benchmark:benchmark-*:1.2.0-alpha08 is released. Version 1.2.0-alpha08 contains these commits.

API Changes

• Added experimental new APIs PerfettoTrace.record {} and PerfettoTraceRule to capture Perfetto traces (also known as System Traces) as part of a test, to inspect test behavior and performance. (I3ba16)
• BaselineProfileRule now accepts a filter predicate instead of a list of package prefixes. This gives the test full control on filtering. (I93240)
• Add an experimental API BaselineProfileRule.collectStableBaselineProfile which waits until a baseline profile is stable for N iterations. (I923f3)
• Add the ability to specify an output file name prefix when generating baseline profiles using BaselineProfileRule. (I7b59f, b/260318655)

Bug Fixes

• Improve safety of file output writing, which should prevent output files from silently not being written / appended, especially on API 21/22. (If8c44, b/227510293)
• Fix simpleperf trace output to create and place the file correctly. This should also more generally fix issues where a file is unsuccessfully pulled by gradle. (I12a1c, b/259424099)
• Improve profileinstaller error message printed when profileinstaller is too old. This now tells you to update profileinstaller version (1.2.1) for measuring baseline profiles on API 31 through 33, instead of saying it's not supported. (Ia517f, b/253519888)
• Fix several shell command failures onerror message Print needed API <=23, including failed perfetto capture binary setup and trace capture failures (Ib6b87, b/258863685)
• Automatically sort generated profile rules to minimize the number of changes as they change over time (when checking-in profile rules into source control). (Ie2509)
• Fixed crash on unrooted builds below Android 13 (API 33) with message Expected no stderr from echo 3 > /proc/sys/vm/drop_caches (I6c245, b/259508183)
• Fix MacrobenchmarkScope.dropShaderCache() to no longer crash by fixing broadcast registry in profileinstaller manifest (I5c728, b/258619948)

Browser: v1.5.0-alpha02

December 7, 2022

androidx.browser:browser:1.5.0-alpha02 is released. Version 1.5.0-alpha02 contains these commits.

API Changes

• Changed the CustomTabsCallback#onActivityResized behavior and added new parameters to it.
• Renamed EXTRA_ACTIVITY_RESIZE_BEHAVIOR to EXTRA_ACTIVITY_RESIZE_HEIGHT_BEHAVIOR to better reflect that it is height specific. (Ic864e)
• Make parts of CustomTabsCallback APIs asynchronous. (Ic86df)

CameraX: v1.2.0

December 7, 2022

androidx.camera:camera-*:1.2.0 is released. Version 1.2.0 contains these commits.

Important changes since 1.1.0

• New library camera-mlkit-vision. Easily integrate CameraX with many MLKit features, including barcode scanning, face detection, text detection, etc. Added MLKitAnalyzer as new APIs.
• New experimental Zero-Shutter Lag API. Optimizes capture pipeline to have better latency while keeping good image quality. When the capture mode is set to CAPTURE_MODE_ZERO_SHUTTER_LAG, the latency between the shutter button is clicked and the picture is taken is expected to be minimized, compared with other capture modes. On devices that don’t support ZERO_SHUTTER_LAG, it’ll fallback to CAPTURE_MODE_MINIMIZE_LATENCY.
• Deprecate android.camera.core.VideoCapture.
• Added setStreamUseCase() as a public Camera2Interop API.
• Added API level requirement for setOutputImageRotationEnabled.
• Renamed ImageAnalysis.Analyzer#getTargetResolutionOverride() to ImageAnalysis.Analyzer#getDefaultTargetResolution().
• Added API for setting location metadata to the saved video.
• Fixed low framerate when using VideoCapture and Preview use cases with 16:9 aspect ratio
• Fixed the black preview issue that happens when BOKEH extension is enabled on some Samsung devices and the user switches the cameras.
• Fixed Samsung J7 Prime (SM-G610M) and J7 (SM-J710MN) Preview/VideoCapture stretched issue on API level 27 devices.
• Disabled the workaround to flip the AF region horizontally of front cameras on Samsung Android T since the issue was fixed

CameraX: v1.3.0-alpha02

December 7, 2022

androidx.camera:camera-*:1.3.0-alpha02 is released. Version 1.3.0-alpha02 contains these commits.

API Changes

• add a new API for applying post-processing effect to Preview output. (Ic17d5)
• Renamed OutputOptions.getDurationLimit to OutputOptions.getDurationLimitMillis and OutputOptions.setDurationLimit to OutputOptions.setDurationLimitMillis. (I91f0c)
• Add AudioConfig class to handle the audio related setting while recording video. The @RequiresPermission annotation is moved from startRecording functions to AudioConfig to avoid unnecessary permission requests for the cases that audio is not needed. (I28755)
• Remove Metadata, OnVideoSavedCallback, OutputFileOptions and OutputFileResults classes that are no longer used after applying the new video capture API. (I38cd8)
• Apply the new video capture API. The getVideoCaptureTargetSize and setVideoCaptureTargetSize methods are replaced with the getVideoCaptureTargetQuality and the setVideoCaptureTargetQuality methods accordingly, as setTargetResolution is no longer supported. (I2a1d5)

Bug Fixes

• Remove deprecated core.VideoCapture API. (I531e0)
• Fixed the issue that the onError callback is not called when taking pictures without the storage permission.(I936db, b/244807669)
• Improve camera extensions quality and reliability. Camera extensions are disabled on Motorola devices using Camera Extensions v1.1.0 and older due to issues with Bokeh support, image capture, and preview not resuming. (Id3ce3)
• Fixed native crash when video cropping via ViewPort is enabled on legacy devices. (I16b8a, b/251357665)

Car App: v1.3.0-rc01

Compose Animation: v1.3.2

December 7, 2022

androidx.compose.animation:animation:1.3.2, androidx.compose.animation:animation-core:1.3.2, and androidx.compose.animation:animation-graphics:1.3.2 are released. Version 1.3.2 contains these commits.

Bug Fixes

• Updated to support androidx.compose.ui 1.3.2

Compose Animation: v1.4.0-alpha03

December 7, 2022

androidx.compose.animation:animation:1.4.0-alpha03, androidx.compose.animation:animation-core:1.4.0-alpha03, and androidx.compose.animation:animation-graphics:1.4.0-alpha03 are released. Version 1.4.0-alpha03 contains these commits.

API Changes

• In UI tests using a Compose rule, continuations resumed during withFrameNanos callbacks will not be dispatched until after all frame callbacks have finished running. This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail. This should only affect code that calls withFrameNanos or withFrameMillis directly, and has logic outside of callback passed to those functions that may need to be moved inside the callbacks. See the animation test changes in this CL for examples.
• Added optional onPerformTraversals: (Long) -> Unit parameter to TestMonotonicFrameClock constructor and factory function to run code after withFrameNanos callbacks but before resuming callers' coroutines. (Idb413, b/254115946, b/222093277, b/255802670)
• New param in AnimatedContent for tooling label (Iebe2d)

Compose Foundation: v1.4.0-alpha03

December 7, 2022

androidx.compose.foundation:foundation:1.4.0-alpha03 and androidx.compose.foundation:foundation-layout:1.4.0-alpha03 are released. Version 1.4.0-alpha03 contains these commits.

API Changes

• In UI tests using a Compose rule, continuations resumed during withFrameNanos callbacks will not be dispatched until after all frame callbacks have finished running. This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail. This should only affect code that calls withFrameNanos or withFrameMillis directly, and has logic outside of callback passed to those functions that may need to be moved inside the callbacks.

• Introduce Page accessibility actions: PageUp, PageDown, PageLeft, PageRight. Note that these are only available from API 29. (Ida4ab)
• Introduce HorizontalPager and VerticalPager, a way of showing composables in a Pager manner. Introduced PagerState to control the Pagers as well as query information about the Pager's current state. Introduced PageSize, a way of controlling the size of a Pager's page, this can be used to create a carousel like Pagers. Introduced PagerSnapDistance, a way to control how snapping will work in Pager's fling behavior. (I01120)
• Introduced an overload in SnapFlingBehavior.performFling to help to understand where the fling will settle. (I569f6)
• Removed OverscrollEffect#isEnabled. Instead of needing to remember and set this flag, just don't dispatch events to the overscroll effect in cases where you do not want overscroll to show (for example if ScrollableState#canScrollForward/backward both return false). (I1a4b0, b/255554340, b/255557085)
• Added ScrollableState#canScrollForward and ScrollableState#canScrollBackward to query whether a ScrollableState has room to scroll in either direction (whether it is at the minimum / maximum of its range). This defaults to true for backwards compatibility with existing implementations of ScrollableState. Consumers can use this to show indication to the user that there is still room to scroll, and this could also be used to avoid dispatching delta to ScrollableStates that have no room to scroll in a given direction, to reduce unnecessary work. (Idf1a0, b/255557085)
• Added an Modifier API to query ancestors scroll info. (I2ba9d, b/203141462)
• Used in Clickable to correctly delay press interactions, when gestures could become scroll events.
• Fixed Clickables not correctly delaying ripples, when used inside an Scrollable ViewGroup.
• Updated Drawers and Sheets to correctly delay presses in case gestures can become scroll events.
• Update snapStepSize naming to be consistent with other methods in SnapLayoutInfoProvider. (Ife67c)
• Added EmojiCompat to Compose (Ibf6f9, b/139326806)
• Renamed consumedWindowInsets() to consumeWindowInsets() and withConsumedWindowInsets() to onConsumedWindowInsetsChanged() and made the Modifiers public. (Ie44e1)

Bug Fixes

• The crash with Modifier.animateItemPlacement() and Lazy grids was fixed. It was happening in some conditions when the new items count is smaller then the previous one. (I0bcac, b/253195989)

Compose Material: v1.4.0-alpha03

December 7, 2022

Wear Compose: v1.2.0-alpha01

December 7, 2022

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

New Features

• We’ve updated the experimental Placeholder functionality so that the “Wipe Off” effect is immediately applied when the content is ready rather than waiting for the next animation loop to start. We have also made some updates to the shimmer and wipe off animations. (I5a7f4)

API Changes

• We have added a HierarchicalFocusCoordinatorcomposable to enable marking sub-trees of the composition as focus enabled or focus disabled.(I827cb)
• We have added a new property to override the semantic role for ToggleButton.(I67132)
• We have updated TimeTextDefaults.TimeFormat12Hours to remove AM/PM in TimeText. This will change the default value of timeSource parameters in TimeText API. (I1eb7f)
• We have extended the Picker API to improve accessibility for screens with multi-picker. There is a new property userScrollEnabled to control whether the picker is active for user scrolling. (I3c3aa)

Bug Fixes

• We have changed the default border width for an OutlinedButton/OutlinedCompactButton from 2.dp to 1.dp to match final UX specs. (Icf84d)
• In order to reduce the effect of the first item added to an empty ScalingLazyColumn appearing to scroll into place we have added an estimated autoCentering topPadding when the contents are empty. This change calculates the amount of top padding needed by assuming an initial item of height 0.dp. For ScalingLazyListAnchorType.ItemStart this will calculate the correct top padding, for ScalingLazyListAnchorType.ItemCenter this calculation will be incorrect as the height of the items is needed to correctly size the contents resulting in a small scroll into place effect based on the items real height.(I239a4)
• We have updated the background scrim applied to the SwipeToDismiss animation to match the Wear platform. (I9003e)
• We have fixed PositionIndicator handling of LazyListState and ScalingLazyListState for list items of size 0 to avoid divide by zero errors.(Ic28dd)

December 7, 2022

androidx.wear.compose:compose-foundation:1.1.0, androidx.wear.compose:compose-material:1.1.0, and androidx.wear.compose:compose-navigation:1.1.0 are released. Version 1.1.0 contains these commits.

Important changes since 1.0.0

• Stable release of Compose for Wear OS 1.1.0 (read more).
• For a list of the key changes in Wear Compose 1.1 see the release notes for (Compose for Wear OS 1.1 Beta01).

New Features

• We’ve updated the experimental Placeholder functionality so that the “Wipe Off” effect is immediately applied when the content is ready rather than waiting for the next animation loop to start. We have also made some updates to the shimmer and wipe off animations. (I5a7f4)

Bug Fixes

• We have changed the default border width for an OutlinedButton/OutlinedCompactButton from 2.dp to 1.dp to match final UX specs. (Icf84d)
• In order to reduce the effect of the first item added to an empty ScalingLazyColumn appearing to scroll into place we have added an estimated autoCentering topPadding when the contents are empty. This change calculates the amount of top padding needed by assuming an initial item of height 0.dp. For ScalingLazyListAnchorType.ItemStart this will calculate the correct top padding, for ScalingLazyListAnchorType.ItemCenter this calculation will be incorrect as the height of the items is needed to correctly size the contents resulting in a small scroll into place effect based on the items real height.(I239a4)
• We have updated the background scrim applied to the SwipeToDismiss animation to match the Wear platform.(I9003e)
• We have fixed PositionIndicator handling of LazyListState and ScalingLazyListState for list items of size 0 to avoid divide by zero errors.(Ic28dd)

Wear Watchface: v1.2.0-alpha05

December 7, 2022

androidx.wear.watchface:watchface-*:1.2.0-alpha05 is released. Version 1.2.0-alpha05 contains these commits.

New Features

• A while back we added support for hierarchical UserStyleSettings, and from android T it’s now possible to have more than one ComplicationSlotsUserStyleSetting in a hierarchy. Only one ComplicationSlotsUserStyleSetting will be active, based on the user’s style selections.

• We’re improving screen reader support for ListOption and ComplicationSlotsOption by adding a screenReaderName field, note prior to android T this field will be ignored by companion editors.

API Changes

• We've added a new optional screenReaderName field to ListOption and ComplicationSlotsOption for use by editors - will be ignored by companion editors on devices before android T. (I75326)
• From android T multiple ComplicationSlotsUserStyleSettings are now supported in a style hierarchy as long as at most only one of them can be active at any one time. We've added a utility function findComplicationSlotsOptionForUserStyle to UserStyleSchema to help find the active ComplicationSlotsOption if any. (Ic2b06)
• RangedValuesTypes have been pulled into RangedValueComplicationData's companion object and renamed to TYPE_UNDEFINED, TYPE_RATING and a new TYPE_PERCENTAGE has been added. (I55d02)
• We've renamed experimental DynamicFloat to FloatExpression and marked it as @hide. (Idf4f1)
• Adding @JvmDefaultWithCompatibility annotation (I8f206)

The apply method should only be called once per process, as early as possible, and will throw IllegalStateException if called more than once. ProcessGlobalConfig objects no longer have any restrictions on how many times setters can be called. (I456c3)
