🛰️ Compose Radar Report - Jul 2, 2026

Here is what Google released this week for Compose:

Compose Runtime

Fixed

• Fixed an ArrayIndexOutOfBoundsException in the new LinkComposer path when nested movableContentOf content recomposes into a different location.

Material 3 Compose

Added

• Added a new expressive scroll variant for TimePicker.

Changed

• Promoted SearchBarState and the slot-based SearchBar APIs to stable, while deprecating the older expanded / onExpandedChange overloads.
• Promoted expressive slider APIs such as VerticalSliderLegacy and SliderDefaults to stable. The previous experimental VerticalSlider now remains as deprecated VerticalSliderLegacy, and the thumb overload that took SliderState is replaced by one that takes isVertical.

Fixed

• Fixed ExposedDropdownMenuBox so Switch Access can activate editable anchors and focus the text field correctly.
• Fixed TextField and OutlinedTextField TalkBack announcement order when prefix or suffix content is present.
• Improved SplitButtonLayout measurement so the trailing action keeps its space and long leading labels wrap less aggressively.

Compose Remote Creation

Added

• Added remote-aware LocalRemoteDensity.
• Added path-building support around RemoteCreationDisplayInfo so remote path construction can be expressed through the new DSL APIs.

Changed

• Exposed RemoteDensityBehavior, density-behavior-aware RemoteCreationDisplayInfo constructors, the densityBehavior property on creation-state APIs, and the public RemoteComposeCreationComposeFlags surface.

Fixed

• Fixed density-dependent corner sizes, RemoteText layout, and modifier resolution when using RemoteDensityBehavior.Dp or overriding local remote density.

Wear Foundation

Added

• Added TransformingLazyColumnFirstLayoutItemProvider plus state helpers such as firstVisibleItemLayoutItemInfo and layoutItemInfoOf, making it easier to control how content shifts during list updates.

Changed

• Enhanced TransformingLazyColumn placement animations so items pushed out of the viewport slide away instead of fading abruptly, while also fixing offscreen scaling snaps during those animations.
• Switched firstVisibleItemLayoutItemInfo to index-based anchoring so reorder and shuffle updates keep the viewport visually pinned to the top edge.

Wear Material 3 Compose

Added

• Exposed ButtonContent, AppCardContent, and TitleCardContent publicly so custom wrappers can reuse standard Wear Material 3 layout, spacing, and typography.
• Added new state-driven coordination around Modifier.oneHandedGesture, replacing the older InteractionSource-based flow for gesture indicators.

Changed

• Temporarily removed built-in one-handed gesture support from AlertDialog due to dependency issues for apps that do not otherwise use the Wear SDK gesture stack.
• Removed the default gestureLabel from Modifier.oneHandedGesture, pushing accessibility labels to call sites explicitly.

Fixed

• Fixed ScreenScaffold so recompositions no longer recreate ScrollInfoProvider and reset scrollAway tracking state.

XR Compose

Added

• Added a new movable overload that takes MovePolicy, while starting the deprecation path for the previous movable and transformingMovable APIs.

Changed

• Changed requestHomeSpace and requestFullSpace to return status results instead of relying on exceptions for reporting.
• Changed session initialization to be asynchronous, so LocalSession and related XR composition locals can resolve to null or non-XR fallbacks until the XR session is ready.
• Deprecated allowUnboundedSubspace on Subspace and removed it from FollowingSubspace; unbounded layouts should now use requiredSizeIn.
• Removed the deprecated semantics modifier overload in the XR subspace modifier stack.
• Removed the deprecated SceneCoreEntitySizeAdapter function.

That's all for this week.
