Webkit Version 1.17

Version 1.17.0

August 12, 2026

androidx.webkit:webkit:1.17.0 is released. Version 1.17.0 contains these commits.

Important Changes Since 1.16.0

• Enhanced Navigation Capabilities (WebViewCompat#navigate): Introduces a modern replacement for WebView#loadUrl. 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): 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): Allows enqueuing preconnect requests in advance without forcing an immediate startup WebView.
• Favicon Download Optimization (WebSettingsCompat#setDownloadFaviconsEnabled): Enables apps to disable automatic Favicon fetching on navigation to reduce memory consumption and network bandwidth.
• Prerender Management (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 Removed experimental Profile#setOriginMatchedHeader (superseded by Profile#addCustomHeader in 1.15.0).
• Proactive Crash Prevention Lint Rule: Adds an AndroidX lint check that flags missing onRenderProcessGone 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.

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.

API Changes

• Added Profile#enqueuePreconnect API to enqueue preconnection requests without triggering immediate WebView startup. (Id7e4a, b/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, b/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.

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, b/501449506)
• Removed incorrect @RequiresFeature annotations on ScriptHandler and UserAgentMetadata#getFormFactors. (Ib9550)

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)

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.

New Features

• Added new APIs: getDownloadFaviconsEnabled and setDownloadFaviconsEnabled. These APIs will allow you to control whether Favicons will be downloaded automatically. (If9224, b/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, b/483041824)
• ExpectedNoVarySearchData is deprecated and updated to ExpectedNoVarySearchHint. ignoredQueryParameters and consideredQueryParameters are made immutable lists. (I7bb8c, b/491718321)

Bug Fixes

• Corrected RequiresFeature annotations on ProcessGlobalConfig to reference isStartupFeatureSupported instead of the incorrect isConfigFeatureSupported. (I6370b)

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.

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, b/408128748)
• Deprecated SpeculativeLoadingParameters. Apps should migrate to the more specific PrerenderParameters or PrefetchParameters for controlling speculative loading features. (I8afed)
• 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)
• Removed the experimental Profile#setOriginMatchedHeader and associated methods. The APIs have been superseded by Profile#addCustomHeader, which was released as a stable API in 1.15.0. (Ia7f5c, b/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.

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 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, NavigationListener, Navigation, and 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 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 and 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 extends the WebView\#saveState 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
• This version of the library introduces WebViewOutcomeReceiver as a library-specific implementation of 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), inject JavaScript and WebMessageListeners into isolated worlds to prevent collisions with existing page JavaScript, and execute JavaScript as a response to a web message (JavaScriptReplyProxy#executeJavaScript).

  Experimental APIs added since 1.15.0

• Added WebViewBuilder.applyTo 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 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. 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.

• 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.

API Changes

• The CallbackExecutor argument to Profile.prefetchUrlAsync is now nullable and defaults to the main thread if not provided. (Ib89ef, b/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.

API Changes

• The startUpWebView 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 has been deprecated, and users of that API should migrate to the new version, which takes a WebViewOutcomeReceiver to facilitate failure callbacks. (Iebb60, I56bf7)
• Navigation APIs no longer require the use of @OptIn annotations.
  This covers WebViewCompat#addNavigationListener, as well as the NavigationListener interface, and the Navigation and 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, b/474625648, b/448580228, b/479792864, b/432696062, b/474625648)
• Removes the experimental annotation from WebViewCompat#saveState. This API is similar to WebView#saveState, but allows the developer to specify a maximum size for the state, and whether forward history entries should be included. (Ie3fe1, b/389076708)
• Profile#setSpeculativeLoadingConfig is deprecated. Use Profile#setMaxPrerenders, PrefetchCache#setMaxPrefetches, PrefetchCache#setPrefetchTtlSeconds instead. (I9f0f7, I9b977, b/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.

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, b/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, b/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)
• Add an api to attch debug information to prefetch request. (Ibb300, b/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, b/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, b/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, I6ef8a, b/487934754)
• Changed return type of StartUpLocation.getStackInformation() from String to Throwable to allow apps to process the information better. (I938d6, b/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 WebMessageListeners 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. (I45d92, b/483103617)

• Add WebViewBuilder.applyTo API for applying builder configurations to pre-constructed WebViews (Iae133, b/463288296)

Version 1.16.0-alpha01

January 14, 2026

androidx.webkit:webkit:1.16.0-alpha01 is released. Version 1.16.0-alpha01 contains these commits.

New Features

• Added new Web Performance Metrics APIs onFirstContentfulPaintMillis, onLargestContentfulPaintMillis and onPerformanceMarkMillis to NavigationListener. These APIs allow developers to track FCP/LCP and performance marks directly in their app instead of using JavaScript to retrieve them. (I50266, b/432696062)
• Adds NAVIGATION_LISTENER_NON_NULL_PAGE_FOR_SAME_DOCUMENT_NAVIGATIONS to WebViewFeature, which can be used to determine whether Navigation#getPage will return null on same-document navigations. (I3a2aa)

Bug Fixes

• Correct nullability of string parameters in getProfilesToLoadDuringStartup (Ic2ce5)
• Expose missing WebViewBuilder feature check constant (I95534)

Version 1.15

Version 1.15.0

December 17, 2025

androidx.webkit:webkit:1.15.0 is released. Version 1.15.0 contains these commits.

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. This will then cause WebView to add a Cookie header to the 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.
• Set custom request headers. The Profile#addCustomHeader 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, app developers can specify which items appear in the context menu when a user long-presses a hyperlink.
• Trigger prerendering. WebViewCompat#prerenderUrlAsync 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 in WebView by calling the WebSettingsCompat#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 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. If you have any feedback on these APIs, please share it either by sending an email to android-webview-dev@chromium.org or by submitting feedback in our issue tracker.

The following features are experimental:

• ProcessGlobalConfig#setUiThreadStartupMode 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 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#startUpWebViewAPI:
  • You can now specify a set of profiles to load 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 and 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 should be run.
• Warm up the renderer process for a Profile by calling 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 allows apps to tell WebView to prefer QUIC / HTTP3 when connecting to the provided origins.
• Profile#preconnect 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 has been updated to allow applications to provide multiple listener instances, which can optionally be configured with a custom Executor for background thread callbacks. This was previously the WebNavigationClient API, which has been deprecated in favour of the new API. Additionally, this update also adds timing information to the onFirstContentfulPaint callback, providing the time information from navigation start to the paint event.

API Changes

• Add experimental WebViewBuilder APIs (I06828, b/409740828)
• Add UiThreadStartupMode for async startup that stops isMultiProcessEnabled() call from startup up Chromium (I524ee, b/397372092)
• Hiding UserAgent form factor until 1.16 release (Ibac8a, b/430554841, b/454438418)
• Update navigation API to allow applications to provide NavigationListener instances, which can optionally be configured with a custom Executor for background thread callbacks. Multiple NavigationListener instances can now be added to a single WebView.
  Additionally, this update also adds timing information to the onFirstContentfulPaint callback, providing the time information from navigation start to the paint event. (I6aa8e, b/448580228)
• Adds Profile#addQuicHints which allows apps to tell WebView to prefer QUIC / HTTP3 when connecting to the provided origins. (I8e364, b/445339041)
• Updated feature constants with experimental annotations, and updated library README with more information about experimental APIs. (I1b914)

Version 1.15.0-alpha03

October 08, 2025

androidx.webkit:webkit:1.15.0-alpha03 is released. Version 1.15.0-alpha03 contains these commits.

API Changes

• Introduces a new API to set custom request headers. 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. (Id7d30, b/419469873, b/429269470)
• Removal of the X-Requested-With header in WebView has been cancelled, and the header will again be sent on all requests by default. The allowlist API is no longer necessary, and has been deprecated. (I884c3, b/447094379)
• Add a new API to WebSettingsCompat to allow developers to configure WebView's back-forward cache, such as setting the timeout in seconds or page cache limits. (I642b2, b/432395269)
• Add HyperlinkContextMenu API to allow item customisation in WebView hyperlink context menu (Idb809, b/382654667)
• Add getAsyncStartUpLocations API for debugging cases where WebView was started up asynchronously without using the startUpWebView API. (I6bf4b, b/417434566)

Version 1.15.0-alpha02

August 27, 2025

androidx.webkit:webkit:1.15.0-alpha02 is released. Version 1.15.0-alpha02 contains these commits.

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)
• A new prerenderUrlAsync 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)
• 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)
• Add a new API to WebSettingsCompat to enabled/disable BackForwardCache on the WebSettings object. This API was previously released as experimental, and can now be used without the @OptIn annotation. (Ie413b)
• 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, b/430554841)

API Changes

• Add API to ProcessGlobalConfig to configure WebView's UI thread initialization (I5e85a, b/433273850, b/397372092)
• Add a new feature name for WebViewStartupConfig.Builder#setProfilesToLoadDuringStartup API (I36451)
• Moving the default minSdk from API 21 to API 23 (Ibdfca, b/380448311, b/435705964, b/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, b/419469873, b/429269470)
• The UI thread requirement for Profile#prefetchUrlAsync() has been removed. It can now be called from any thread. (I83d57)
• 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)
• Renames [is/set]IncludeCookiesOnShouldInterceptRequestEnabled to [are/set]CookiesIncludedInShouldInterceptRequest in WebSettingsCompat. (Ife9e9, b/428924452)
• Adding experimental API annotations to Profile.ExperimentalUrlPrefetch that had previously been omitted. (Ic54eb, b/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.

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, b/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() 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, b/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)

API Changes

• Add a new method to the experimental Navigation interface to provide the URL of the navigation. (I1c6c0)
• Update the Profile Prefetch feature name to clarify that the Prefetch API can now be invoked on a background thread. (I7c83a)

PaymentRequest is disabled by default and WebView host apps can call WebSettingsCompat.setPaymentRequestEnabled(settings, true) to enable it. In addition, PaymentRequest requires a <queries> tag in AndroidManifest.xml. See documentation for setPaymentRequestEnabled() for more information. (I3304e, b/404920055)
• Introducing Experimental Navigation Callbacks. This release introduces experimental APIs for enhanced web navigation tracking and management within WebView. These APIs provide detailed information about navigation events. Key Features:
  • WebNavigationClient Interface: Introduces a new interface, WebNavigationClient, with callbacks for navigation events:
  • onNavigationStarted(Navigation navigation): Notifies when a navigation begins.
  • onNavigationRedirected(Navigation navigation): Notifies when a navigation is redirected.
  • onNavigationCompleted(Navigation navigation): Notifies when a navigation completes.
  • Navigation Interface: Provides detailed information about a navigation, including: URL, page initiation status, same-document status, reload status, history status, back/forward status, commit status, error page status, status code, and session restore status. The Navigation object serves as a unique identifier for each navigation, allowing developers to correlate related navigation events.
  • Page class: Introduces the Page class, which serves as a key for page-associated data. (I351a6)
• Introduce a new experimental API to toggle the behaviour of caching provider objects. (I14636)

API Changes

• Updated the PROFILE_URL_PREFETCH feature value in WebViewFeature. (I606fd)
• Adds WebViewCompat#saveState, akin to WebView#saveState, but allows restricting the size of the returned state and deciding whether or not to save forward history entries. (Iea7d6)
• Add maxPrerenders config to SpeculativeLoadingConfig API (I67245)

Important changes since 1.12.0

• Introduce a new experimental API for Url prerendering to allow developers to speculative prerender candidate urls resulting in faster navigations. (I0cfe7)
• Introducing a set of new APIs to delete browsing data stored by WebView. The new APIs in WebStorageCompat should be preferred over the existing APIs in android.webkit.WebStorage, as they will guarantee deletion of all local storage, including the network cache and cookies, as well as any installed service workers. If new storage APIs are introduced in the future, then these new methods will be updated to include them in the storage deleted. (Iad54f, b/382273208)
• Add setPartitionedCookiesEnabled API. This will allow developers to enable and disable partitioned cookies in WebView. (Ic506a, b/364904765)

Version 1.9.0

November 29, 2023

androidx.webkit:webkit:1.9.0 is released. Version 1.9.0 contains these commits.

Important changes since 1.8.0

• Added a new multi-profile API for WebViews.
  • The Profile interface has different APIs to use to get associated data with this profile such as its name, GeoLocationPermissions, ServiceWorkerController, CookieManager and 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 method and retrieved using WebViewCompat#getProfile
  • The newly introduced ProfileStore let you manage the available profiles in your application, including the default profile.
  • Existing WebView APIs such as CookieManager#getInstance will continue to operate on the Default profile.
• Added an API to inject and run Javascript before page load.
  • The WebViewCompat#addDocumentStartJavascript 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, this API will allow execution of scripts in embedded Iframes when they load. Apps can use this new API in combination with WebViewCompat#addWebMessageListener 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 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.
• Added APIs to override user-agent metadata for client hints.
  • We introduced a new API, WebSettingsCompat#setUserAgentMetadata 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 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 to ensure the correct values are being used in all situations.

Version 1.9.0-rc01

November 15, 2023

• Annotating ProfileStore, WebViewCompat#setProfile and WebViewCompat.getProfile with @UiThread. (I499b2)

Version 1.9.0-alpha01

October 18, 2023

androidx.webkit:webkit:1.9.0-alpha01 is released. Version 1.9.0-alpha01 contains these commits.

New Features

• We added the multi-profile API which allows you to have separate browsing sessions between WebViews, each profile has its own data (e.g. cookies). 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, ServiceWorkerController, CookieManager and WebStorage. Each WebView will run with the default profile by default however, you can change that using WebViewCompat#setProfile Related to that, a WebViews profile can be retrieved using WebViewCompat#getProfile. (I32d22)
• Add APIs to modify how Attribution Reporting events are registered. We introduced a new API WebSettingsCompat#setAttributionRegistrationBehavior which allows developers to configure whether 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. (I661f2)
• Add APIs to override user-agent metadata. 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)
• Add an API to inject Javascript to be run during page load. The WebViewCompat.addDocumentStartJavascript API allows apps to inject scripts into a WebView which will be 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, this API will allow execution of scripts in embedded Iframes when they load. (Ide063)

January 25, 2023

androidx.webkit:webkit:1.6.0 is released. Version 1.6.0 contains these commits.

Important changes since 1.5.0

• A new ProcessGlobalConfig API has been added to allow apps to provide configuration settings that need to be set before loading WebView, such as the WebView data directory suffix. 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 API has been added to expand 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 the effect of EnterpriseAuthenticationAppLinkPolicy if set by admin in WebView, and to get the current setting. 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 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

ProcessGlobalConfig objects no longer have any restrictions on how many times setters can be called. (I456c3)

Version 1.6.0-alpha03

November 9, 2022

androidx.webkit:webkit:1.6.0-alpha03 is released. Version 1.6.0-alpha03 contains these commits.

New Features

• Add ProcessGlobalConfig class enabling users to set process global config before loading WebView. WebView has some process-global configuration parameters that cannot be changed once WebView has been loaded (e.g. the WebView data directory). 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. (I7c0e0, b/250553687)
• Adding new API 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. (I0adfe, b/226552535)

API Changes

• The WebSettingsCompat#setAlgorithmicDarkeningAllowed API is supported on all Android versions in WebView version 105 and later. Previous versions of WebView only supported the API on Android Q and later. As a result, this api is no longer marked @RequiresApi(Build.VERSION_CODES.Q). (I3ac1d)

Version 1.3.0

Version 1.3.0

August 19, 2020

androidx.webkit:webkit:1.3.0 is released. Version 1.3.0 contains these commits.

Major changes since 1.2.0

• ForceDarkStrategy API provides more control to WebView darkening (CSS/web content darkening versus auto darkening).
• WebMessageListener and its related APIs provide a simple and secure mechanism to establish communication between web contents and the WebView embedder app.
• isMultiProcessEnabled API to check whether WebView is running in multi process. This is possible starting in Android O and it means web content is rendered in a sandboxed renderer process separate to the application process. This sandboxed renderer may be shared with other WebViews in the same application but it's not shared with other application processes.
