Compose 1.12.0 went stable August 12, and alpha01 of 1.13 dropped the same day. FlexBox graduates from experimental (no more @OptIn), a new SelectionState API gives you programmatic text selection control, and click sounds are now automatic on Android.

Compose 1.12.0 hit stable August 12 alongside Fragment 1.9.0, Tracing 2.0.0, and Navigation3 1.1.6. What's genuinely new vs RC01 (WCG, variable fonts, Dialog blur), what breaks on upgrade, and the exact migration checklist before you bump the BOM.

X shipped a fully rebuilt Android app on July 20, 2026 — 100% Kotlin, Jetpack Compose end to end, and Kotlin Multiplatform powering X Chat's E2E encryption across Android, iOS, and Web. Here's what a year-long clean-slate rewrite looks like and what every Android engineer can take from it.

Seven alphas, one beta, and the Benchmark library has its most consequential upgrade since stable. UiAutomator 2.4 lands in MacrobenchmarkScope, requireAot flips to true by default to stop silent JIT-warm measurements, TraceProcessor moves to benchmark-common, and beta01 lets PerfettoCapture merge Tracing 2.0 in-process events into one Perfetto file.

Fragment 1.9.0 is at RC01. Three practical changes: fragment-ktx is absorbed into the main artifact (Jake Wharton contribution), AndroidFragment gets a maxLifecycle param to fix lifecycle leaks in Compose pagers, and Fragment officially enters maintenance mode. Here's what each means and what to do about it.

Media3 1.11.0 graduated to stable on August 5. Beyond what alpha01 and beta01 shipped, stable adds OggMuxer and WavMuxer for audio output, MP4 chapter extraction, enablePerStreamMediaProgression() for startup latency, HLS Content Steering, and five API removals to fix before you upgrade.

Google's official Android Skills are built for deprecation by design — every skill should eventually make itself obsolete as models improve. The philosophy, the evaluation framework (think integration tests for AI knowledge), when skills actually add value, and why only ~20 official ones exist.

RC01 shipped July 29 — stable is weeks away. Beyond the visual APIs covered in beta, 1.12 adds SoundEffectOnInteraction for accessibility-aware click sounds, credentialRequest Semantics for passkey-ready Compose login forms, a breaking TextObfuscationMode rename in BasicSecureTextField, and InterceptPlatformTextInput promoted to stable.

Three new experimental layout primitives bring CSS-inspired adaptive layouts to Jetpack Compose: FlexBox for flowing content sections, a structural Grid for 2D panels without lazy loading, and mediaQuery() for branching on device posture, pointer precision, and viewing distance — not just window width.

Navigation 2.10.0-beta01 ships multiplatform support for Desktop, macOS, iOS, WASM, tvOS, and watchOS; NavBackStackEntryInfo for custom predictive back animations; NavUri replacing android.net.Uri; and a deep link security fix. Plus the honest maintenance mode reality check and a decision tree for Navigation 2.x vs Navigation3.

Google's 'Build intelligent Android apps' series introduced @Generable annotations for type-safe structured output via KSP, and a new genai-speech-recognition 1.0.0-alpha1 library. Here's the integration guide: setup, data class annotations, streaming transcription, and how to go from 13-second receipts parsing to under 2 seconds.

Google's Play Age Signals API expands to Australia and Canada in mid-August, then globally by year-end. Integration guide with AgeSignalsManager, the four default age tiers, testing with FakeAgeSignalsManager, and the strict policy restrictions that govern what you can actually do with the data.

Seven security and privacy behavior changes in Android 17 that aren't in the other posts: ACCESS_LOCAL_NETWORK permission for LAN access, banned static-final reflection, enforced ECH and Certificate Transparency, stricter native DCL, Contacts Provider 2 PII removal, and more.

Alpha25 lands six API renames and two deprecations as M3 Expressive hardens toward stable — trailingIcon becomes trailingContent, TonalToggleButton becomes FilledTonalToggleButton, SplitButtonLayout is deprecated, and ComponentOverride is removed entirely. Plus alpha24's new material3-ripple artifact for inset focus rings.

Alpha07 adds BackStackMatcher — a declarative way to build a synthetic back stack when handling deep links — plus DeepLinkSerializer for complex argument types, five targeted bug fixes, and Navigation3 1.1.5 stable on the same day.

Navigation3 1.2.0-alpha05/06 adds UriDeepLinkMatcher for URI-to-NavKey resolution and ResultEventBus for typed result passing between destinations — the two features that 1.1.4 stable shipped without. Full API surface with real code.

As of July 22, your Play Store app listing is available to rival US stores by default. Downloads still flow through Play, billing is unchanged, but you now have a decision to make in Play Console. Here's the opt-in/out trade-off, the Epic settlement context, and what actually changes in your app (spoiler: nothing in the APK).

Samsung announced Galaxy Glasses at Unpacked today — phone-tethered, display-free, Gemini Live API as the app model. One codebase targets headset, display glasses, and audio glasses at runtime. Here's the developer model that matters before hardware ships this fall.

Alpha19 lands EditablePdfDocument for inline form filling with autofill, a pdf-core module split that decouples document models from the UI layer, OcrProvider APIs for scanned documents, and public AnnotationView. The case for dropping your third-party PDF SDK just got stronger.

Tracing 2.0.0-beta01 replaces the android.os.Trace wrapper with a full in-process Perfetto engine. TraceDriver brings metadata-tagged slices, coroutine context propagation across suspend/resume boundaries, and JVM support — the tracing story production apps actually needed.

Quail 2 (2026.1.2) is stable. Run multiple Gemini agent chats in parallel, get LeakCanary heap analysis at 5x speed on your development machine, and triage production crashes with full source context — not just the stack trace.

Beta01 lands Format.selectionPriority for HLS/DASH adaptive streaming, multi-Location DASH fallback for CDN resilience, and fixes a ForegroundServiceStartNotAllowedException crash that bites every background music app.

DataStore 1.3.0-alpha finally adds Tink-backed AES-256-GCM encryption, a new DataStore.Builder that enforces application-scoped context, and Kotlin Multiplatform Web support with OPFS, localStorage, and sessionStorage.

Alpha02 lands pinch-to-zoom and tap-to-focus natively in CameraXViewfinder, adds a Night Mode Indicator API, exposes GPU-native ImageAnalysis via HardwareBuffer, and brings granular audio controls and AE/AWB locking to the recorder.

FloatingToolbar, ButtonGroup, WavyProgressIndicator, and 10+ other Expressive APIs graduated to stable in alpha23. Plus a unified rememberBottomSheetState() that deprecates two separate sheet state APIs. Here's what to adopt today.

asItemSnapshotListFlow() converts your PagingData flow into a standard Flow you can combine() with other state, and the new append/prepend/refresh/retry methods give you manual load control that isn't tied to scroll position.

Android Bench migrated to Harbor on July 8 — adding latency, cost, and CI range dimensions. Claude Fable 5 tops at 84.5%, open-weight models now included. Here's how to read the leaderboard for your actual Android workflow.

AppFunctions is Android 16's on-device MCP equivalent — annotate Kotlin suspend functions, write clear KDoc, and AI agents like Gemini discover and execute your app's capabilities without the user opening your UI.

rememberHiltViewModelFactory() drops the ViewModelStoreOwner parameter, the Compose artifact is now separate from navigation, and paired with Lifecycle 2.11's rememberViewModelStoreOwner it finally makes per-Pager-page Hilt ViewModels clean to write.
