Version 1.19.0-alpha01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/fb536a9a01ea26779570787c8a6af74256f17cb0..21b800145da7b651ce947785e2e20815a3132c9d/webkit/webkit). **API Changes** - Fix accidental hidden callback on `NavigationListener` ([I1cd2e](https://android-review.googlesource.com/#/q/I1cd2e8bbaa6c3b827f44d8223ad68af2525b02df), [b/576625538](https://issuetracker.google.com/issues/576625538)) - Added an overload of `WebViewCompat#startUpWebView` that accepts an `Executor` on which to invoke the `WebViewOutcomeReceiver` callback, allowing applications to handle startup completion on a background thread rather than the main looper. ([I51748](https://android-review.googlesource.com/#/q/I517483734a80c8d8662e454a9b8ce955be526593)) - Changed `Navigation/Page#snapshotState` to `#captureState` and edited `NavigationState#didCommitErrorPage` javadoc ([I0405a](https://android-review.googlesource.com/#/q/I0405a2d341e77bae624e70e05148ed658c9e291a)) - Adds `NavigationState` and `PageState` which are immutable copies of `Navigation` and `Page` at a certain point in time. They are supplied via new callbacks within `NavigationListener`, which have `NavigationState` and `PageState` as parameters instead of `Navigation` and `Page`. The state objects can also be supplied by `Navigation#snapshotState` and `Page#snapshotState`. - Added `NavigationState#getNavigationStartUptimeMillis` which returns the navigation's start up time in milliseconds. - Added `NavigationState#getResponseHeaders` and `NavigationRedirectParameters` which is supplied via `onNavigationRedirect(NavigationState,NavigationRedirectParameters)` which exposes the HTTP response headers for the Navigation. ([I9886a](https://android-review.googlesource.com/#/q/I9886a73001f22295762a7cc268812454c86347f1)) - Added support for `Profile#addQuicHints` to take wildcards as URLs (such as `https://*.example.com` or \`https://\*) ([Ic6d67](https://android-review.googlesource.com/#/q/Ic6d67d674316386681dbabb4c28d22c2a0297051), [b/442161273](https://issuetracker.google.com/issues/442161273)) - Deprecated `WebSettingsCompat.getAttributionRegistrationBehavior`, `WebSettingsCompat.setAttributionRegistrationBehavior`, and related constants as `WebView` no longer supports Attribution Reporting in version 152 and later. ([I3453a](https://android-review.googlesource.com/#/q/I3453a4cf11826a8d6fd3bcd4ce9fef83f4a73e09), [b/528282384](https://issuetracker.google.com/issues/528282384)) ## Webkit ### Version 1.18 ### Version 1.18.0-rc01 October 07, 2026 `androidx.webkit:webkit:1.18.0-rc01` is released. Version 1.18.0-rc01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/b2b5ae7b0fe1bb4eece7018878fe5f18c5967a2f..69f085f69ab093b8540b58892cdbbefb88f20e94/webkit/webkit). **Bug Fixes** - Clarified in documentation that Profile custom request header changes take effect on document load. ([Id3b6f](https://android-review.googlesource.com/#/q/Id3b6fc1e7657e7e1248b2c6253c00526892221b3), [b/561650101](https://issuetracker.google.com/issues/561650101)) ## Version 1.18 ### Version 1.18.0 October 21, 2026 `androidx.webkit:webkit:1.18.0` is released. Version 1.18.0 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/013da5fafa75f04bd7850047ad492700d7a10335..fb536a9a01ea26779570787c8a6af74256f17cb0/webkit/webkit). **Important changes since 1.17.0:** - **Cross-Origin Isolation Management:** Introduces new profile-level APIs (`Profile#setCrossOriginIsolatedAllowlist` and `getCrossOriginIsolatedAllowlist`) to allow the use of `SharedArrayBuffer` and other APIs that require [cross-origin isolation](https://developer.mozilla.org/en-US/docs/Web/API/Window/crossOriginIsolated). Web pages must also opt in by setting the [`Document-Isolation-Policy`](https://developer.chrome.com/blog/document-isolation-policy) header as appropriate. When this feature is used, origins on the allowlist will be permitted to use these APIs despite not being fully cross-origin isolated. Care must be taken to only allowlist trusted origins. - **Prefetch Queue Draining Control:** Adds a new `WEBVIEW_NAVIGATE_DRAIN_PREFETCH` constant to `WebViewFeature` which can be used to determine whether `Navigation#navigate` will drain the prefetch queue before navigating to the new URL. - **API Modernization \& Cleanups:** Includes several method renames for clarity. `PrefetchParameters#isJavaScriptEnabled` has been renamed to `includeClientHints`, with the older method now marked as deprecated, and `isJavaScriptEnabled` marked as deprecated. Additionally, `Profile#addQuicHints` has been renamed to `preferQuicFor`. ### Version 1.18.0-alpha02 September 23, 2026 `androidx.webkit:webkit:1.18.0-alpha02` is released. Version 1.18.0-alpha02 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/e4bd62f853853bf3522ed15681c58ef28b09ed44..b84c5dac76c0b59a5da8d54b2db2e8e1c7175665/webkit/webkit). ### Version 1.18.0-alpha01 September 09, 2026 `androidx.webkit:webkit:1.18.0-alpha01` is released. Version 1.18.0-alpha01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/86a006fbdf97644dbc4072bf0ee700e15ce02986..3b87180049780b1f2b8f0fd7b42372a617394079/webkit/webkit). **New Features** - Added `Profile#setCrossOriginIsolatedAllowlist` and `Profile#getCrossOriginIsolatedAllowlist` API to opt out of origin isolation security features, allowing the use of `SharedArrayBuffer`. ([I889d3](https://android-review.googlesource.com/#/q/I889d38a9362c2ea94370fe796357d8194925a4e2), [b/545572447](https://issuetracker.google.com/issues/545572447)) **API Changes** - Renames `PrefetchParameters#isJavaScriptEnabled` to `includeClientHints`. `isJavaScriptEnabled` is marked as deprecated. ([I269d3](https://android-review.googlesource.com/#/q/I269d341e2299d72e312240bf830f8c509947aba0), [b/537260697](https://issuetracker.google.com/issues/537260697)) - Adds `WEBVIEW_NAVIGATE_DRAIN_PREFETCH` to `WebViewFeature`, which can be used to determine whether Navigation#navigate will drain the prefetch queue before navigating to the new URL. ([I6a7a9](https://android-review.googlesource.com/#/q/I6a7a9000bc4383d220ae74126afe7deb47694a51)) - Renames `Profile#addQuicHints` to `preferQuicFor`. ([I9a663](https://android-review.googlesource.com/#/q/I9a66326cc7e39d6fbd4b23af96ac7becadec59bf)) ## Webkit Version 1.17 ### Version 1.17.1 September 23, 2026 `androidx.webkit:webkit:1.17.1` is released. Version 1.17.1 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/86a006fbdf97644dbc4072bf0ee700e15ce02986..013da5fafa75f04bd7850047ad492700d7a10335/webkit/webkit). **Bug Fixes** - Removed Kotlin from the `webkit` library to unblock apps that have issues with kotlinc. ### Version 1.17.0 August 12, 2026 `androidx.webkit:webkit:1.17.0` is released. Version 1.17.0 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/5744fa6296a0f6147952e836b3d92dd87ff7d4dd..86a006fbdf97644dbc4072bf0ee700e15ce02986/webkit/webkit). **Important Changes Since 1.16.0** - **Enhanced Navigation Capabilities ([`WebViewCompat#navigate`](https://developer.android.com/reference/kotlin/androidx/webkit/WebViewCompat#navigate(android.webkit.WebView,java.lang.String,androidx.webkit.NavigationParameters))):** Introduces a modern replacement for [`WebView#loadUrl`](https://developer.android.com/reference/android/webkit/WebView#loadUrl(java.lang.String,%20java.util.Map%3Cjava.lang.String,java.lang.String%3E)). Key capabilities include replacing history entries, returning a trackable `Navigation` object, and consistent header persistence during state save/restore. - **HTTP Cache Quota Control ([`Profile#getHttpCache`](https://developer.android.com/reference/kotlin/androidx/webkit/Profile#getHttpCache())):** Provides APIs to inspect and adjust profile-level HTTP cache quotas, benefiting static-content-heavy applications and reducing cache directory footprint when unused. - **Preconnection Queueing ([`Profile#enqueuePreconnect`](https://developer.android.com/reference/kotlin/androidx/webkit/Profile#enqueuePreconnect(java.lang.String))):** Allows enqueuing preconnect requests in advance without forcing an immediate startup WebView. - **Favicon Download Optimization ([`WebSettingsCompat#setDownloadFaviconsEnabled`](https://developer.android.com/reference/kotlin/androidx/webkit/WebSettingsCompat#setDownloadFaviconsEnabled(android.webkit.WebSettings,boolean))):** Enables apps to disable automatic Favicon fetching on navigation to reduce memory consumption and network bandwidth. - **Prerender Management ([`Profile#getMaxPrerenders`](https://developer.android.com/reference/kotlin/androidx/webkit/Profile#getMaxPrerenders()) / `clearMaxPrerenders`):** Introduces methods to retrieve and reset maximum allowed concurrent prerenders. - **API Modernization \& Cleanups:** Deprecated `SpeculativeLoadingParameters` in favor of `PrerenderParameters` / `PrefetchParameters`. Removed experimental `Profile#setOriginMatchedHeader` (superseded by [`Profile#addCustomHeader`](https://developer.android.com/reference/androidx/webkit/Profile#addCustomHeader(androidx.webkit.CustomHeader)) in 1.15.0). - **Proactive Crash Prevention Lint Rule:** Adds an AndroidX lint check that flags missing [`onRenderProcessGone`](https://developer.android.com/reference/android/webkit/WebViewClient#onRenderProcessGone(android.webkit.WebView,%20android.webkit.RenderProcessGoneDetail)) implementations when a custom `WebViewClient` is attached, encouraging developers to handle renderer crashes gracefully. ### Version 1.17.0-rc01 July 29, 2026 `androidx.webkit:webkit:1.17.0-rc01` is released. Version 1.17.0-rc01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/e37cf4eae99bdc35def1209921d658612e2edbc3..678a668bbdc36a8cba0176b1551cb64d90e12427/webkit/webkit). There are no changes since `androidx.webkit:webkit:1.17.0-alpha04` ### Version 1.17.0-alpha04 July 15, 2026 `androidx.webkit:webkit:1.17.0-alpha04` is released. Version 1.17.0-alpha04 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/ba3014c143b9c9782fe30bc766c5dced55e13453..903140ec0e76f2d1c0d1ab18afeeb326f8fc5706/webkit/webkit). **API Changes** - Added `Profile#enqueuePreconnect` API to enqueue preconnection requests without triggering immediate `WebView` startup. ([Id7e4a](https://android-review.googlesource.com/#/q/Id7e4a0206746df4fa155fd78c33946afd3ed9025), [b/511156405](https://issuetracker.google.com/issues/511156405)) - Added `WebSettingsCompat#setDownloadFaviconsEnabled` and `WebSettingsCompat#getDownloadFaviconsEnabled` which allows developers to set or get whether a Favicon will be downloaded upon a navigation, by disabling the downloading of Favicons there will be a decrease in memory and bandwidth. ([I9f87e](https://android-review.googlesource.com/#/q/I9f87e3ba0ceaad2af5d7e60e86fb9d7ee48de49a), [b/510229667](https://issuetracker.google.com/issues/510229667)) ### Version 1.17.0-alpha03 July 01, 2026 `androidx.webkit:webkit:1.17.0-alpha03` is released. Version 1.17.0-alpha03 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/14c2f2ed81d0f61a3227641684cd875e95dd6529..f7668b81600bdf22bc975d3fc38e6fd22c94b585/webkit/webkit). **API Changes** - Added an `HttpCache` API, accessible via `Profile#getHttpCache`, providing the ability to query and manage the HTTP cache quota for a profile. This can benefit the performance and availability of apps which rely heavily on web-served static content, or alternatively reduce cache directory usage where HTTP caching is not needed. This feature requires `WebView` version M151 or higher. ([I40a7f](https://android-review.googlesource.com/#/q/I40a7fcc6370a80afab7e825ec6ec1ce7bca6950f), [b/501449506](https://issuetracker.google.com/issues/501449506)) - Removed incorrect `@RequiresFeature` annotations on `ScriptHandler` and `UserAgentMetadata#getFormFactors`. ([Ib9550](https://android-review.googlesource.com/#/q/Ib955074b281a2f2f0ea92c31e5a9807ded2c5e4c)) **Lint Checks** - Introduced a lint warning for unhandled `onRenderProcessGone` callback. This callback gives developers an opportunity to gracefully recover from a render process shutting down rather than crashing their app. A warning will be linted if a `WebViewClient` has been used but it has not overridden this callback. ([Ia4e41](https://android-review.googlesource.com/#/q/Ia4e4117807bfb34dad392d774a4041682059eb73)) ### Version 1.17.0-alpha02 June 17, 2026 `androidx.webkit:webkit:1.17.0-alpha02` is released. Version 1.17.0-alpha02 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/b5d2acb5ad0a36c9d2aba8feb4c7951165f30fbe..14c2f2ed81d0f61a3227641684cd875e95dd6529/webkit/webkit). **New Features** - Added new APIs: `getDownloadFaviconsEnabled` and `setDownloadFaviconsEnabled`. These APIs will allow you to control whether Favicons will be downloaded automatically. ([If9224](https://android-review.googlesource.com/#/q/If922448ab7e6ade223c241ce429f7213c436e931), [b/510229667](https://issuetracker.google.com/issues/510229667)) **API Changes** - Update the `prefetchUrlAsync` API that accepts `PrefetchResult` as a callback type to report users if there is a duplicate prefetch request. ([Icc796](https://android-review.googlesource.com/#/q/Icc79674269aeba0f42746109f17b455217e19218), [b/483041824](https://issuetracker.google.com/issues/483041824)) - `ExpectedNoVarySearchData` is deprecated and updated to `ExpectedNoVarySearchHint`. `ignoredQueryParameters` and `consideredQueryParameters` are made immutable lists. ([I7bb8c](https://android-review.googlesource.com/#/q/I7bb8cbb22fcd6f2ba77ad1d7ae15c3d874ba0bd9), [b/491718321](https://issuetracker.google.com/issues/491718321)) **Bug Fixes** - Corrected `RequiresFeature` annotations on `ProcessGlobalConfig` to reference `isStartupFeatureSupported` instead of the incorrect `isConfigFeatureSupported`. ([I6370b](https://android-review.googlesource.com/#/q/I6370bc2413fdb443c1231a84ea581e2c5702a118)) ### Version 1.17.0-alpha01 May 19, 2026 `androidx.webkit:webkit:1.17.0-alpha01` is released. Version 1.17.0-alpha01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/5744fa6296a0f6147952e836b3d92dd87ff7d4dd..b5d2acb5ad0a36c9d2aba8feb4c7951165f30fbe/webkit/webkit). **API Changes** - Added `WebViewCompat#navigate`, an enhanced version of `WebView#loadUrl`. Like `loadUrl`, this method will load the specified url in the `WebView`, but offers the following additional capabilities: - Allows replacing the current page in the navigation history. - Returns a Navigation object, allowing the developer to match between the navigate call and navigation callbacks. - Handles extra headers in a more consistent and understandable manner, including saving and restoring them when using save state. ([Iedefd](https://android-review.googlesource.com/#/q/Iedefd179043f289d6dc905995c979119adf1d0df), [b/408128748](https://issuetracker.google.com/issues/408128748)) - Deprecated `SpeculativeLoadingParameters`. Apps should migrate to the more specific `PrerenderParameters` or `PrefetchParameters` for controlling speculative loading features. [(I8afed)](https://android-review.googlesource.com/q/I8afed51cd6b037a9907f10015fbbc02f7c23a3a8) - Added new methods to `Profile` to manage prerendering behavior: `Profile#getMaxPrerenders()` to get the current limit and `Profile#clearMaxPrerenders()` to reset it to the default. ([I696ed](https://android-review.googlesource.com/#/q/I696eddc59807ba85890583fe83066a260aadffb3)) - Removed the experimental `Profile#setOriginMatchedHeader` and associated methods. The APIs have been superseded by [Profile#addCustomHeader](https://developer.android.com/reference/androidx/webkit/Profile#addCustomHeader(androidx.webkit.CustomHeader)), which was released as a stable API in `1.15.0`. ([Ia7f5c](https://android-review.googlesource.com/#/q/Ia7f5cff673f5bfc152e575c660aaa57736161072), [b/485235632](https://issuetracker.google.com/issues/485235632)) ## Webkit Version 1.16 ### Version 1.16.0 May 06, 2026 `androidx.webkit:webkit:1.16.0` is released. Version 1.16.0 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/f35ed15ba0388327d2b70a31d141da182ff721c8..5744fa6296a0f6147952e836b3d92dd87ff7d4dd/webkit/webkit). **Important changes since 1.15.0:** The 1.16.0 stable release brings multiple APIs out of experimental status, significantly improving stability and developer experience for features like async `WebView` startup and navigation listening. The minimum supported SDK (minSdk) for this library has been increased to 24. - The [`startUpWebView`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#startUpWebView(android.content.Context,androidx.webkit.WebViewStartUpConfig,androidx.webkit.WebViewOutcomeReceiver%3Candroidx.webkit.WebViewStartUpResult,androidx.webkit.WebViewStartupException%3E)) API and related async startup configuration APIs in `ProcessGlobalConfig` and `WebViewStartUpConfig` have been graduated from experimental to stable. These APIs let applications trigger WebView startup earlier, ensuring portions of the startup run in the background to improve responsiveness. The previous version of `startUpWebView` has been deprecated, and users should migrate to the new version, which takes a `WebViewOutcomeReceiver` to facilitate failure callbacks. - The navigation APIs, including [`WebViewCompat\#addNavigationListener`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#addNavigationListener(android.webkit.WebView,java.util.concurrent.Executor,androidx.webkit.NavigationListener)), [`NavigationListener`](https://developer.android.com/reference/androidx/webkit/NavigationListener), [`Navigation`](https://developer.android.com/reference/androidx/webkit/Navigation), and [`Page`](https://developer.android.com/reference/androidx/webkit/Page) have been graduated to stable. These APIs let app developers receive callbacks from WebView during the different stages of page navigation through the [`NavigationListener`](https://developer.android.com/reference/androidx/webkit/NavigationListener) interface. This also includes the option to receive performance metrics from the page, which makes it easier for app developers to measure performance of first-party pages in their apps. The [`Navigation`](https://developer.android.com/reference/androidx/webkit/Navigation) and [`Page`](https://developer.android.com/reference/androidx/webkit/Page) objects serve as unique identifiers that serve as the link between the different callbacks when multiple WebViews or navigations might be happening concurrently. The `Navigation` object also provides more information about the specific nature of the ongoing navigation, including how it was started, and whether it succeeded or resulted in an error page, while the `Page` object provides the specific URL. - [`WebViewCompat\#saveState`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#saveState(android.webkit.WebView,android.os.Bundle,int,boolean)) extends the [`WebView\#saveState`](https://developer.android.com/reference/android/webkit/WebView.html#saveState(android.os.Bundle)) method with more controls that allow developers to specify a maximum size for the state and whether forward history entries should be included. The saved state object is still compatible with [`WebView\#restoreState`](https://developer.android.com/reference/android/webkit/WebView.html#restoreState(android.os.Bundle)) - This version of the library introduces [`WebViewOutcomeReceiver`](https://developer.android.com/reference/androidx/webkit/WebViewOutcomeReceiver) as a library-specific implementation of [`android.os.OutcomeReceiver`](https://developer.android.com/reference/android/os/OutcomeReceiver), which allows this library to provide a similar mechanism for asynchronous callback result handling without a need to depend on higher `targetSdk` values. This class was named `androidx.webkit.OutcomeReceiverCompat` while in experimental status but has been renamed to avoid any name clashes. - **External Contribution:** New APIs were introduced to inject persistent `JavaScript` as part of the document loaded event ([`WebViewCompat#addJavaScriptOnEvent`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#addJavaScriptOnEvent(android.webkit.WebView,java.lang.String,int,java.util.Set%3Cjava.lang.String%3E,androidx.webkit.JavaScriptExecutionWorld))), inject `JavaScript` and `WebMessageListeners` into [isolated worlds](https://developer.android.com/reference/androidx/webkit/JavaScriptExecutionWorld) to prevent collisions with existing page `JavaScript`, and execute `JavaScript` as a response to a web message ([`JavaScriptReplyProxy#executeJavaScript`](https://developer.android.com/reference/androidx/webkit/JavaScriptReplyProxy#executeJavaScript(java.lang.String,androidx.webkit.WebViewOutcomeReceiver%3Cjava.lang.String,androidx.webkit.JavaScriptExecutionException%3E))). **Experimental APIs added since 1.15.0** - Added [`WebViewBuilder.applyTo`](https://developer.android.com/reference/androidx/webkit/WebViewBuilder#applyTo(T)) API for applying builder configurations to pre-constructed `WebViews`. This lets you use the configuration capabilities of the `WebViewBuilder` API, and the corresponding guarantees that settings won't change, with pre-existing `WebView` objects. This is intended to be used with `WebView` instances created from layout inflation, or with subclasses of `WebView`. **Experimental APIs updated since 1.15.0** - The [`BackForwardCacheSettings`](https://developer.android.com/reference/androidx/webkit/BackForwardCacheSettings) object has been changed from a configuration object that is provided through `WebSettingsCompat` to a live object that can be obtained by calling [WebSettingsCompat#getBackForwardCacheSettings](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#getBackForwardCacheSettings(android.webkit.WebSettings)). The object now has setter methods that update the settings directly. The previous `Builder` nested class has been removed, as has `WebSettingsCompat#setBackForwardCacheSettings.` Apps that previously used these methods will experience build errors when upgrading. - `Profile#setSpeculativeLoadingConfig` is deprecated. Use `Profile#setMaxPrerenders`, `PrefetchCache#setMaxPrefetches`, and `PrefetchCache#setPrefetchTtlSeconds` instead. - Removed `Profile#clearPrefetchAsync` as it was a no-op. - Changed the return type of `StartUpLocation.getStackInformation()` from `String` to `Throwable` to allow apps to process the information better. ### Version 1.16.0-rc01 April 22, 2026 `androidx.webkit:webkit:1.16.0-rc01` is released. Version 1.16.0-rc01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/951845221205b7a428a9d779107760fc929863ee..69a3842c3da27089adcfd5f6593cace86258fa9b/webkit/webkit). - There are no changes since `androidx.webkit:webkit:1.16.0-beta01` . ### Version 1.16.0-beta01 April 08, 2026 `androidx.webkit:webkit:1.16.0-beta01` is released. Version 1.16.0-beta01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/4f1927c2c3b66d0c3a6b9118974d818d2dc5a06a..cf4acc3c7b7fb09822200e21faddec615955dafe/webkit/webkit). **API Changes** - The `CallbackExecutor` argument to `Profile.prefetchUrlAsync` is now nullable and defaults to the main thread if not provided. ([Ib89ef](https://android-review.googlesource.com/#/q/Ib89ef77acac24aa312d13f1328abf0dfc1710fce), [b/483041824](https://issuetracker.google.com/issues/483041824)) ### Version 1.16.0-alpha04 March 25, 2026 `androidx.webkit:webkit:1.16.0-alpha04` is released. Version 1.16.0-alpha04 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/1a508f033de883ba2853b9f9ae1853eec7010638..4f1927c2c3b66d0c3a6b9118974d818d2dc5a06a/webkit/webkit). **API Changes** - The [`startUpWebView`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#startUpWebView(android.content.Context,androidx.webkit.WebViewStartUpConfig,androidx.webkit.WebViewOutcomeReceiver)) API and related async startup configuration APIs in `ProcessGlobalConfig` and `WebViewStartUpConfig` have been graduated from experimental to stable. WebView startup can be a time-consuming process, so these APIs allow applications to trigger WebView startup at the right time, ensuring that portions of WebView startup which are able to run in the background will do so, improving the responsiveness of the first WebView usage. These APIs were previously released as experimental, and can now be used without an `@OptIn` annotation. The [previous version of `startUpWebView`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#startUpWebView(android.content.Context,androidx.webkit.WebViewStartUpConfig,androidx.webkit.WebViewCompat.WebViewStartUpCallback)) has been deprecated, and users of that API should migrate to the new version, which takes a `WebViewOutcomeReceiver` to facilitate failure callbacks. ([Iebb60](https://android-review.googlesource.com/#/q/Iebb606901c73244f24f9d9f78bfa8dde6e8f791f), [I56bf7](https://android-review.googlesource.com/#/q/I56bf73694714021668fd6e3497c68020f2983b17)) - Navigation APIs no longer require the use of `@OptIn` annotations. This covers [`WebViewCompat#addNavigationListener`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#addNavigationListener(android.webkit.WebView,java.util.concurrent.Executor,androidx.webkit.NavigationListener)), as well as the [`NavigationListener`](https://developer.android.com/reference/androidx/webkit/NavigationListener) interface, and the [Navigation](https://developer.android.com/reference/androidx/webkit/Navigation) and [Page](https://developer.android.com/reference/androidx/webkit/Page) classes. Note that the `Navigation` and `Page` types are now classes instead of interfaces. These APIs should now be feature checked using the new `WebViewFeature#NAVIGATION_LISTENER` feature constant. ([I410c8](https://android-review.googlesource.com/#/q/I410c8377e6139cbb5f6e65999701fec8f1ce5907), [b/474625648](https://issuetracker.google.com/issues/474625648), [b/448580228](https://issuetracker.google.com/issues/448580228), [b/479792864](https://issuetracker.google.com/issues/479792864), [b/432696062](https://issuetracker.google.com/issues/432696062), [b/474625648](https://issuetracker.google.com/issues/474625648)) - Removes the experimental annotation from [`WebViewCompat#saveState`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#saveState(android.webkit.WebView,android.os.Bundle,int,boolean)). This API is similar to [`WebView#saveState`](https://developer.android.com/reference/android/webkit/WebView#saveState(android.os.Bundle)), but allows the developer to specify a maximum size for the state, and whether forward history entries should be included. ([Ie3fe1](https://android-review.googlesource.com/#/q/Ie3fe1e984db78d359f3f4c7d2a46f1be62d8f30b), [b/389076708](https://issuetracker.google.com/issues/389076708)) - `Profile#setSpeculativeLoadingConfig` is deprecated. Use `Profile#setMaxPrerenders`, `PrefetchCache#setMaxPrefetches`, `PrefetchCache#setPrefetchTtlSeconds` instead. ([I9f0f7](https://android-review.googlesource.com/#/q/I9f0f744d0fb419be6f2505d68695ba77a0de82de), [I9b977](https://android-review.googlesource.com/#/q/I9b97740a1c0826132cd0b6dabb7d6f2a34958285), [b/466301565](https://issuetracker.google.com/issues/466301565)) ### Version 1.16.0-alpha03 March 11, 2026 `androidx.webkit:webkit:1.16.0-alpha03` is released. Version 1.16.0-alpha03 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/cdf076c6abd0f3125cb0302756fcb77fe981ab7c..1a508f033de883ba2853b9f9ae1853eec7010638/webkit/webkit). **New Features** - Added new Web Performance Metrics APIs `onFirstContentfulPaintMillis`, `onLargestContentfulPaintMillis` and `onPerformanceMarkMillis` to `NavigationListener`. These APIs allow developers to track First/Largest Contentful Paint and performance marks directly in their app instead of using JavaScript to retrieve them. ([Idb93b](https://android-review.googlesource.com/#/q/Idb93b3661861a723d1d0429e7aab6ad779ee52f2), [b/432696062](https://issuetracker.google.com/issues/432696062)) - Added error information to the Navigation object, see `Navigation#getWebResourceError` and `WebResourceError#getDebugCode.` If a navigation load fails due to a net error, error information about why this occurred is now available on the navigation object. ([I18bdc](https://android-review.googlesource.com/#/q/I18bdcf902e63e5726f0b985e46978ce29d3fdaf5), [b/474625648](https://issuetracker.google.com/issues/474625648)) - Update the API shape of `BackForwardCache` settings by a new `BackForwardCacheSettings` object that can be obtained by calling `WebSettingsCompat#getBackForwardCacheSettings`, and can be used to alter each setting through set/get methods. Note: We are removing `WebSetingsCompat#setBackForwardCacheSettings` and `BackForwardCacheSettings.Builder`, so this change may cause compilation errors when you update to this version if you were using the removed API. ([I377f4](https://android-review.googlesource.com/#/q/I377f434d6dc93b2c0fde9cd82c49ff37eaa06f37)) - Add an api to attch debug information to prefetch request. ([Ibb300](https://android-review.googlesource.com/#/q/Ibb30018c5154fc01d6aa0bdc75c67133150f0fef), [b/474559983](https://issuetracker.google.com/issues/474559983)) **API Changes** - The minimum supported SDK (minSdk) has been increased to 24. Apps targeting SDK versions below 24 will need to update their target SDK to use this and future versions of the library. ([I4df32](https://android-review.googlesource.com/#/q/I4df32317770517242777fb87b41f17c27a0d1dc4), [b/452708695](https://issuetracker.google.com/issues/452708695)) - Removed the experimental `Profile#clearPrefetchAsync` since it was no-op. This was in-development functionality that never worked. If you need to clear the cache, please submit a feature request. ([I341a4](https://android-review.googlesource.com/#/q/I341a4e62142ab0bbe439bbceddec00902359873b), [b/483043529](https://issuetracker.google.com/issues/483043529)) - Migrate `androidx.webkit.OutcomeReceiverCompat` to stable status, and renamed it to `WebViewOutcomeReceiver`. This library-specific copy of the interface allows the `webkit` library to maintain `compileSdk = 33`, and the new name prevents name clashes. ([I0ebf7](https://android-review.googlesource.com/#/q/I0ebf70c1a865512c57185e5edba8dc92a155af5a), [I6ef8a](https://android-review.googlesource.com/#/q/I6ef8a1d6016d354d948f94352b955417ebd11fa7), [b/487934754](https://issuetracker.google.com/issues/487934754)) - Changed return type of `StartUpLocation.getStackInformation()` from `String` to `Throwable` to allow apps to process the information better. ([I938d6](https://android-review.googlesource.com/#/q/I938d6669c83acc98c71a4a83ef5cd02160a18e98), [b/417434566](https://issuetracker.google.com/issues/417434566)) **External Contribution** - Introducing new APIs to - Inject persistent JavaScript as part of the document loaded event. This works similar to the existing `WebViewCompat#addDocumentStartJavaScript`, but ensures that the DOM is ready when the script runs. The new API is `WebViewCompat#addJavaScriptOnEvent`. - Inject JavaScript and `WebMessageListener`s into isolated worlds, to prevent collisions with existing page JavaScript. The new APIs are `WebViewCompat#addJavaScriptOnEvent` and `WebViewCompat#addWebMessageListener`. - Execute JavaScript as response to a web message sent from a page in the same frame/world combo that sent the message. The new API is `JavaScriptReplyProxy#executeJavaScript`.

Version 1.15.0 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/e0db6d8bb2835e53b913e6bf0a913b68f6aaf6d7..f35ed15ba0388327d2b70a31d141da182ff721c8/webkit/webkit). **Important changes since 1.14.0** This release increases the `minSdk` from API 21 to API 23. It also introduces the following new API capabilities: - Access and set cookies as part of `shouldInterceptRequest` callbacks for WebView and Service Workers. App developers who currently access the `CookieManager` API as part of their `shouldInterceptRequest` can now instead enable cookie headers directly by calling [WebViewCompat#setCookiesIncludedInShouldInterceptRequest](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setCookiesIncludedInShouldInterceptRequest(android.webkit.WebSettings,boolean)). This will then cause `WebView` to add a `Cookie` header to the [WebResourceRequest.getRequestHeaders()](https://developer.android.com/reference/android/webkit/WebResourceRequest#getRequestHeaders()) map which will be the exact cookies that apply to the request. This will also correctly handle any partitioned cookies. Apps can provide `Set-Cookie` header values through the newly added [WebResourceResponseCompat#setCookies](https://developer.android.com/reference/androidx/webkit/WebResourceResponseCompat#setCookies(java.util.List%3Cjava.lang.String%3E)) API. The `Set-Cookie` values added there will be processed by `WebView` as part of the response handling. - Set custom request headers. The [Profile#addCustomHeader](https://developer.android.com/reference/androidx/webkit/Profile#addCustomHeader(androidx.webkit.CustomHeader)) API allows app developers to set a list of static header name-value pairs, which will be sent on any requests that match the specified origin pattern. - Allow item customization in WebView hyperlink context menu. By calling [WebViewCompat#setHyperlinkContextMenuItems](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setHyperlinkContextMenuItems(android.webkit.WebSettings,int)), app developers can specify which items appear in the context menu when a user long-presses a hyperlink. - Trigger [prerendering](https://developer.chrome.com/docs/web-platform/prerender-pages). [WebViewCompat#prerenderUrlAsync](https://developer.android.com/reference/androidx/webkit/WebViewCompat#prerenderUrlAsync(android.webkit.WebView,java.lang.String,android.os.CancellationSignal,java.util.concurrent.Executor,androidx.webkit.PrerenderOperationCallback)) allows applications to speculatively prerender URLs before they are displayed in a `WebView`. Prerendering can dramatically improve loading performance by fetching the page ahead of time. When the user navigates to the URL, the prerendered page is displayed instantly. - Control the specifics of the [BackForwardCache](https://developer.chrome.com/blog/back-forward-cache) in `WebView` by calling the [WebSettingsCompat#setBackForwardCacheSettings](http://setBackForwardCacheSettings) API. This API allows you to set the timeout in seconds or adjust the page cache limits. - Finally, the removal of the `X-Requested-With` header in `WebView` has been canceled, and the header will again be sent on all requests. The [allowlist API](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setRequestedWithHeaderOriginAllowList(android.webkit.WebSettings,java.util.Set%3Cjava.lang.String%3E)) is thus no longer necessary, and has been deprecated. **Experimental APIs added since 1.14.0** - The `WebView` library has also introduced a number of APIs that currently have experimental status. You can read more about these APIs in the [package summary](https://developer.android.com/reference/kotlin/androidx/webkit/package-summary#experimental-apis). If you have any feedback on these APIs, please share it either by sending an email to [android-webview-dev@chromium.org](mailto:android-webview-dev@chromium.org) or by submitting feedback in our [issue tracker](https://issuetracker.google.com/issues/new?component=460423). The following features are experimental: - [ProcessGlobalConfig#setUiThreadStartupMode](https://developer.android.com/reference/androidx/webkit/ProcessGlobalConfig#setUiThreadStartupMode(android.content.Context,int)) allows you to configure WebView's UI thread initialization. In particular, this will let you choose whether startup should run as a single task, or should be split into smaller tasks that yield control to the UI thread Looper. - Create `WebView` instances with a restricted configuration that cannot be changed afterwards with the [WebViewBuilder](https://developer.android.com/reference/androidx/webkit/WebViewBuilder) API. Initially, this means that it is now possible to add JavaScript interface objects that are only injected in a specified list of origins, which greatly improves the security of using it. This will then also disable any further calls to `addJavascriptInterface` on the constructed `WebView` instance, which ensures an immutable configuration. - Expanded on the [WebViewCompat#startUpWebView](https://developer.android.com/reference/androidx/webkit/WebViewCompat#startUpWebView(android.content.Context,androidx.webkit.WebViewStartUpConfig,androidx.webkit.WebViewCompat.WebViewStartUpCallback))API: - You can now specify a [set of profiles to load](https://developer.android.com/reference/androidx/webkit/WebViewStartUpConfig.Builder#setProfilesToLoadDuringStartup(java.util.Set%3Cjava.lang.String%3E)) synchronously. This allows app developers to skip loading any profiles at all, or specify the exact set of profiles the app uses, to ensure they are all loaded. - Debugging async startup is now easier by using the [getUiThreadBlockingStartUpLocations](https://developer.android.com/reference/androidx/webkit/WebViewStartUpResult#getUiThreadBlockingStartUpLocations()) and [getNonUiThreadBlockingStartUpLocations](https://developer.android.com/reference/androidx/webkit/WebViewStartUpResult#getNonUiThreadBlockingStartUpLocations()) callbacks to determine locations in the app where WebView startup blocks either the UI thread or a background thread. - You can configure how `WebView`'s [UI thread initialization](https://developer.android.com/reference/androidx/webkit/ProcessGlobalConfig#setUiThreadStartupModeV2(android.content.Context,int)) should be run. - Warm up the renderer process for a Profile by calling [Profile#warmUpRendererProcess](https://developer.android.com/reference/androidx/webkit/Profile#warmUpRendererProcess()). This API can be used by applications with complex `WebView` lifecycles to ensure that the renderer process is running, even if all WebView instances have been destroyed. - [Profile#addQuicHints](https://developer.android.com/reference/kotlin/androidx/webkit/Profile#addQuicHints(java.util.Set%3Cjava.lang.String%3E)) allows apps to tell `WebView` to prefer QUIC / HTTP3 when connecting to the provided origins. - [Profile#preconnect](https://developer.android.com/reference/androidx/webkit/Profile#preconnect(java.lang.String)) allows apps to open a connection to an origin before navigating to it in order to speed up future loads. **Experimental APIs updated since 1.14.0** - The [Navigation Listener API](https://developer.android.com/reference/androidx/webkit/NavigationListener) has been updated to allow applications to [provide multiple listener instances](https://developer.android.com/reference/androidx/webkit/WebViewCompat#addNavigationListener(android.webkit.WebView,java.util.concurrent.Executor,androidx.webkit.NavigationListener)), which can optionally be configured with a custom Executor for background thread callbacks. This was previously the [WebNavigationClient API](https://developer.android.com/reference/androidx/webkit/WebViewCompat#setWebNavigationClient(android.webkit.WebView,androidx.webkit.WebNavigationClient)), which has been deprecated in favour of the new API. Additionally, this update also adds timing information to the [onFirstContentfulPaint](https://developer.android.com/reference/androidx/webkit/WebNavigationClient#onFirstContentfulPaint(androidx.webkit.Page)) callback, providing the time information from navigation start to the paint event. ### Version 1.15.0-rc01 December 03, 2025 `androidx.webkit:webkit:1.15.0-rc01` is released.

This is an iteration on the previous experimental API, and now allows the application to set multiple values for each header, each mapped to a different set of origin patterns. The new API also allows the application to inspect the configured headers.

Version 1.15.0-alpha02 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/1b437892629a2cdedb46d9b7232575987b2cc6b5..cd8ce2bdb21194a81a76325a8e65dad5d7e28681/webkit/webkit). **New Features** - Adds `Profile#preconnect` which allows apps to open a connection to an origin before navigating to it in order to speed up future loads. ([I8db41](https://android-review.googlesource.com/#/q/I8db410905622dea61d31322d4ad88afe30dccabc)) - A new [`prerenderUrlAsync`](https://developer.android.com/reference/androidx/webkit/WebViewCompat#prerenderUrlAsync(android.webkit.WebView,java.lang.String,android.os.CancellationSignal,java.util.concurrent.Executor,androidx.webkit.PrerenderOperationCallback)) API has been added to `WebViewCompat`, allowing applications to speculatively prerender URLs before they are displayed in a WebView. Prerendering can dramatically improve loading performance by fetching the page ahead of time. When the user navigates to the URL, the prerendered page is displayed instantly. These APIs were previously released as experimental, and can now be used without the `@OptIn` annotation. ([Ie14f5](https://android-review.googlesource.com/#/q/Ie14f5e58ccf53e28bfbf63a0e071d62f991b9a70)) - You can now specify a set of profiles to load synchronously when calling the `startUpWebView` API. This is configured by passing the profile names to a new method in `WebViewStartUpConfig.Builder` ([I9a6e6](https://android-review.googlesource.com/#/q/I9a6e6a25f3f19d79a6b5a5bbbfbe2214559acf9c)) - Add a new API to `WebSettingsCompat` to enabled/disable [BackForwardCache](https://developer.chrome.com/blog/back-forward-cache) on the `WebSettings` object. This API was previously released as experimental, and can now be used without the `@OptIn` annotation. ([Ie413b](https://android-review.googlesource.com/#/q/Ie413ba37340e467e8949d2281b6bd313fc4b3a0d)) - Add support for overriding User-Agent form factors, The `UserAgentMetadata` class has new methods to get and set user-agent metadata form factors. The `UserAgentMetadata.Builder` has a new `setFormFactors()` method for overriding the `Sec-CH-UA-Form-Factors` User-Agent client hint. The current override values can be retrieved via the new `getFormFactors()` method. ([I6d08c](https://android-review.googlesource.com/#/q/I6d08c9c7403bead863182cbbde93fcae809d2d9f), [b/430554841](https://issuetracker.google.com/issues/430554841)) **API Changes** - Add API to `ProcessGlobalConfig` to configure `WebView`'s UI thread initialization ([I5e85a](https://android-review.googlesource.com/#/q/I5e85a13fd0e0378bcb09b1f9ddc2d2510a3a2018), [b/433273850](https://issuetracker.google.com/issues/433273850), [b/397372092](https://issuetracker.google.com/issues/397372092)) - Add a new feature name for `WebViewStartupConfig.Builder#setProfilesToLoadDuringStartup` API ([I36451](https://android-review.googlesource.com/#/q/I36451e15092610c874e99e9a7d209a79438ed0ae)) - Moving the default minSdk from API 21 to API 23 ([Ibdfca](https://android-review.googlesource.com/#/q/Ibdfca5942dbb414ca07594ba240093db14aad4df), [b/380448311](https://issuetracker.google.com/issues/380448311), [b/435705964](https://issuetracker.google.com/issues/435705964), [b/435705223](https://issuetracker.google.com/issues/435705223)) - Update origin matched header API to allow overwriting header values by calling `setOriginMatchedHeader` multiple times for the same header name. Also adds a new `hasOriginMatchedHeader` method to check if the header name is already in use. This change also marks the API as experimental, as it currently only supports setting a single value and origin mapping for each header value, and it will likely undergo changes in the future to make it support multiple values mapped to different origins. ([I03365](https://android-review.googlesource.com/#/q/I033651e3ea50a4263da7438f7522af7052a85ec5), [b/419469873](https://issuetracker.google.com/issues/419469873), [b/429269470](https://issuetracker.google.com/issues/429269470)) - The UI thread requirement for `Profile#prefetchUrlAsync()` has been removed. It can now be called from any thread. ([I83d57](https://android-review.googlesource.com/#/q/I83d5761e5d2384b66415d770bf0c0dfc54d299be)) - The `OutcomeReceiverCompat` interface has been removed in favor of the official `androidx.core.os.OutcomeReceiverCompat` version. The library now requires `compileSdk` 35 or higher. ([Ie1ea5](https://android-review.googlesource.com/#/q/Ie1ea50e6945402b245416145048213d389c2159e)) - Renames `[is/set]IncludeCookiesOnShouldInterceptRequestEnabled` to `[are/set]CookiesIncludedInShouldInterceptRequest` in `WebSettingsCompat`.

([Ic54eb](https://android-review.googlesource.com/#/q/Ic54eb7fc6176a032820f13cf46627d76197e2cc7), [b/417458061](https://issuetracker.google.com/issues/417458061)) ### Version 1.15.0-alpha01 July 2, 2025 `androidx.webkit:webkit:1.15.0-alpha01` is released. Version 1.15.0-alpha01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/e0db6d8bb2835e53b913e6bf0a913b68f6aaf6d7..1b437892629a2cdedb46d9b7232575987b2cc6b5/webkit/webkit). **New Features** - A new API to set HTTP header name-value pairs on requests to specific origins. The `Profile.setOriginMatchedHeader` method lets the application specify that the header name and value should be set on all HTTP/HTTPS requests to the origins that match the provided allowlist when sent from WebViews and service workers that use the given Profile. The API only allows a single mapping for each header name, and will throw an exception if the header name is already set. Use `Profile.clearOriginMatchedHeader` to remove an existing mapping, and `Profile.clearAllOriginMatchedHeaders` to remove all mappings. ([Ida7f1](https://android-review.googlesource.com/#/q/Ida7f131d30731734b9ca29f9e67fca95f9a429d3), [b/419469873](https://issuetracker.google.com/issues/419469873)) - A new API to access and set cookies as part of `shouldInterceptRequest` callbacks for WebView and Service Workers. App developers who currently access the `CookieManager` API as part of their `shouldInterceptRequest` can now enable cookie headers directly by calling `setIncludeCookiesOnShouldInterceptRequest`. This will then cause WebView to add a `Cookie` header to the [WebResourceRequest.getRequestHeaders()](https://developer.android.com/reference/android/webkit/WebResourceRequest#getRequestHeaders()) map which will be the exact cookies that apply to the request. This will also correctly handle any partitioned cookies. Apps can provide `Set-Cookie` header values through the newly added `WebResourceResponseCompat.setCookies` API. The `Set-Cookie` values added there will be processed by WebView as part of the response handling. ([Idbfd1](https://android-review.googlesource.com/#/q/Idbfd14469ebc1eb0278a3eae3ea18ee4272cb2c6), [b/414769380](https://issuetracker.google.com/issues/414769380)) - A new experimental API to warm up the renderer process for a `Profile`. This API can be used by applications with complex WebView lifecycles to ensure that the renderer process is running, even if all WebView instances have been destroyed. ([Ia8fc8](https://android-review.googlesource.com/#/q/Ia8fc858b9b26de3abe9168c47e82cf382638cd05)) **API Changes** - Add a new method to the experimental [Navigation](https://developer.android.com/reference/androidx/webkit/Navigation) interface to provide the URL of the navigation. ([I1c6c0](https://android-review.googlesource.com/#/q/I1c6c0ee582cb4a6855adc9cd224569fc8bef4aef)) - Update the Profile Prefetch feature name to clarify that the Prefetch API can now be invoked on a background thread. ([I7c83a](https://android-review.googlesource.com/#/q/I7c83ad4effc502e1b19cc4b44e608f5e42bbe793)) ## Version 1.14 ### Version 1.14.0 June 4, 2025 `androidx.webkit:webkit:1.14.0` is released.

In addition, `PaymentRequest` requires a `` tag in `AndroidManifest.xml`. See documentation for `setPaymentRequestEnabled()` for more information. - Introducing the experimental Navigation API for enhanced web navigation tracking and management within `WebView`. These APIs provide detailed information about navigation events. Get started by calling [WebViewCompat.setNavigationClient](https://developer.android.com/reference/androidx/webkit/WebViewCompat#setWebNavigationClient(android.webkit.WebView,androidx.webkit.WebNavigationClient)) with an implementation of the new [WebNaviagationClient](https://developer.android.com/reference/androidx/webkit/WebNavigationClient) interface to get detailed information about page navigation.

[Version 1.9.0 contains these commits.](https://android.googlesource.com/platform/frameworks/support/+log/40bb8c8db91df80e03503485d4964664f87cde66..d905464a8027b0af72851565b52e77892405085d/webkit/webkit) **Important changes since 1.8.0** - **Added a new multi-profile API for WebViews.** - The [Profile](https://developer.android.com/reference/androidx/webkit/Profile) interface has different APIs to use to get associated data with this profile such as its name, [GeoLocationPermissions](https://developer.android.com/reference/android/webkit/GeolocationPermissions), [ServiceWorkerController](https://developer.android.com/reference/android/webkit/ServiceWorkerController), [CookieManager](https://developer.android.com/reference/android/webkit/CookieManager) and [WebStorage](https://developer.android.com/reference/android/webkit/WebStorage). These objects are specific to the profile, and information is not shared between different profiles in the application. - The profile used by a `WebView` instance can be changed using the [WebViewCompat#setProfile](https://developer.android.com/reference/androidx/webkit/WebViewCompat#setProfile(android.webkit.WebView,java.lang.String)) method and retrieved using [WebViewCompat#getProfile](https://developer.android.com/reference/androidx/webkit/WebViewCompat#getProfile(android.webkit.WebView)) - The newly introduced [ProfileStore](https://developer.android.com/reference/androidx/webkit/ProfileStore) let you manage the available profiles in your application, including the default profile. - Existing WebView APIs such as [CookieManager#getInstance](https://developer.android.com/reference/android/webkit/CookieManager#getInstance()) will continue to operate on the Default profile. - **Added an API to inject and run Javascript before page load.** - The [WebViewCompat#addDocumentStartJavascript](https://developer.android.com/reference/androidx/webkit/WebViewCompat#addDocumentStartJavaScript(android.webkit.WebView,java.lang.String,java.util.Set%3Cjava.lang.String%3E)) API allows apps to inject scripts into a `WebView` which are guaranteed to run before any page scripts are executed. The API allows the app to specify a target list of origins for the script to be enabled on, ensuring that it only runs on intended pages. Unlike [WebView#evaluateJavascript](https://developer.android.com/reference/android/webkit/WebView#evaluateJavascript(java.lang.String,%20android.webkit.ValueCallback%3Cjava.lang.String%3E)), this API will allow execution of scripts in embedded Iframes when they load. Apps can use this new API in combination with [WebViewCompat#addWebMessageListener](https://developer.android.com/reference/androidx/webkit/WebViewCompat#addWebMessageListener(android.webkit.WebView,java.lang.String,java.util.Set%3Cjava.lang.String%3E,androidx.webkit.WebViewCompat.WebMessageListener)) to set up two-way communication with JavaScript in the page in a reliable way. - **Added APIs to modify how Privacy Sandbox Attribution Reporting events are registered.** - We introduced a new API [WebSettingsCompat#setAttributionRegistrationBehavior](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setAttributionRegistrationBehavior(android.webkit.WebSettings,int)) which allows developers to configure whether attribution sources and triggers are registered as coming from the app itself or coming from the web content in the WebView. This method can also be used to disable Attribution Reporting in WebView. Additionally we added a new API `WebSettingsCompat#getAttributionRegistrationBehavior` to get the current behavior. - For more information see the [Privacy Sandbox documentation](https://developer.android.com/design-for-safety/privacy-sandbox/attribution-app-to-web#attribution_source_and_trigger_registration_from_webview). - **Added APIs to override user-agent metadata for client hints.** - We introduced a new API, [WebSettingsCompat#setUserAgentMetadata](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setUserAgentMetadata(android.webkit.WebSettings,androidx.webkit.UserAgentMetadata)) to override the user-agent metadata for WebView used to populate the user-agent client hints, and we also added another new API [WebSettingsCompat#getUserAgentMetadata](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#getUserAgentMetadata(android.webkit.WebSettings)) to get current user-agent overrides. We encourage apps to use the new API to set the right override values whenever the app changes the default user agent string using [WebSettings.setUserAgentString](https://developer.android.com/reference/android/webkit/WebSettings#setUserAgentString(java.lang.String)) to ensure the correct values are being used in all situations. ### Version 1.9.0-rc01 November 15, 2023 `androidx.webkit:webkit:1.9.0-rc01` is released. This release contains no changes from the `1.9.0-beta01` release. ### Version 1.9.0-beta01 November 1, 2023 `androidx.webkit:webkit:1.9.0-beta01` is released.

You can create profiles, assign them to `WebView` instances, and retrieve them later for any data access. There is a singleton class `ProfileStore` to help you manage profiles by creation or deletion with APIs; `getOrCreateProfile`, `getProfile`, `getAllProfileNames` and `deleteProfile`. The `Profile` class will have different APIs to use to get associated data with this profile such as its name, [`GeoLocationPermissions`](https://developer.android.com/reference/android/webkit/GeolocationPermissions), [`ServiceWorkerController`](https://developer.android.com/reference/android/webkit/ServiceWorkerController), [`CookieManager`](https://developer.android.com/reference/android/webkit/CookieManager) and [`WebStorage`](https://developer.android.com/reference/android/webkit/WebStorage). Each `WebView` will run with the default profile by default however, you can change that using `WebViewCompat#setProfile` Related to that, a `WebView`'s profile can be retrieved using `WebViewCompat#getProfile`. ([I32d22](https://android-review.googlesource.com/#/q/I32d2278b5028d43bb49a0dbc71d13ab594bcba11)) - Add APIs to modify how Attribution Reporting events are registered.

We introduced a new API `WebSettingsCompat#setUserAgentMetadata` to override the user-agent metadata for WebView, which is used to populate the user-agent client hints, and we also added another new API `WebSettingsCompat#getUserAgentMetadata` to get current user-agent overrides. We encourage apps to use the new API to set the right override values instead of relying on changing user-agent. ([I74500](https://android-review.googlesource.com/#/q/I745009a8c24d287416787802fb29210a78967855)) - Add an API to inject Javascript to be run during page load.

You can enable your users to drag images out of the `WebView` by adding the new [`DropDataContentProvider`](https://developer.android.com/reference/androidx/webkit/DropDataContentProvider) to your app's manifest as described in the class documentation. - We added the [`ProcessGlobalConfig#setDirectoryBasePaths(Context,File,File)`](https://developer.android.com/reference/androidx/webkit/ProcessGlobalConfig#setDirectoryBasePaths(android.content.Context,java.io.File,java.io.File)) API which can be used to set the base directories that `WebView` will use for the current process. As with all methods on `ProcessGlobalConfig`, this method must be called before the first instance of `WebView` is instantiated. This method is added to provide Android framework the capability to tweak `WebView` settings. For general purpose applications, using this method is not recommended. ### Version 1.7.0-rc01 May 10, 2023 `androidx.webkit:webkit:1.7.0-rc01` is released with no changes since `1.7.0-beta01`.

The configuration should be set up and applied as early as possible during application startup, to ensure that it happens before any other thread can call a method that loads `WebView` into the process. - A new [CookieManagerCompat](https://developer.android.com/reference/androidx/webkit/CookieManagerCompat) API has been added to expand [android.webkit.CookieManager](https://developer.android.com/reference/android/webkit/CookieManager) with a new `getCookieInfo` method, which retrieves all attributes for all cookies set on a specific URL. This differs from the existing getCookie API in `CookieManager` which returns only the name and value attributes of the cookies. - `WebSettingsCompat` has new methods to [enable/disable](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setEnterpriseAuthenticationAppLinkPolicyEnabled(android.webkit.WebSettings,boolean)) the effect of `EnterpriseAuthenticationAppLinkPolicy` if set by admin in `WebView`, and to [get the current setting](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#getEnterpriseAuthenticationAppLinkPolicyEnabled(android.webkit.WebSettings)). This feature lets WebView open an Authentication app instead of opening the authentication URL. This feature has no effect on devices that are not managed by an enterprise policy. - Adding [a new API](https://developer.android.com/reference/androidx/webkit/WebSettingsCompat#setRequestedWithHeaderOriginAllowList(android.webkit.WebSettings,java.util.Set%3Cjava.lang.String%3E)) to `WebSettingsCompat` to let applications explicitly send the app package name in the `X-Requested-With` header to allowlisted origins. The header has traditionally been sent on every request from `WebView`. ### Version 1.6.0-rc01 January 11, 2023 `androidx.webkit:webkit:1.6.0-rc01` is released.

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.

This class allows apps to set these parameters. The configuration should be set up and applied as early as possible during application startup, to ensure that it happens before any other thread can call a method that loads `WebView` into the process.

Apps targeting SDK 33 and higher (T) should use the new API, as the old API will no longer have any effect for those apps. - An allow-list of URLs to use the configured proxy can now be set through `ProxyCofig.Builder` by setting `setReverseBypassEnabled` to `true`. When this is in effect, all other URLs will bypass the configured proxy. ### Version 1.5.0-rc01 August 10, 2022 `androidx.webkit:webkit:1.5.0-rc01` is released with no changes since `1.5.0-beta01`.
