Closing this in favour of #57, which contains only the intended one-line change. Apologies for the noise: I filed a batch of these and two target repositories shared a repository name, so both pull requests ended up pointing at the same branch on my fork. The later push overwrote the earlier one, which is why this PR showed unrelated commits and files. Nothing was wrong with your repository. #57 is on its own branch and shows the single guard change. |

- Line 121: Fix the component lifecycle issue causing native UI-automation input
to stop working after switching tabs, then remove the skip from the
“MultiMessaging Tab” test suite so multi-switch coverage runs again. Preserve
the existing navigation behavior while ensuring the Windows example remains
interactive across repeated tab switches.
- Line 72: Fix the Windows event path so window.ReactNativeWebView.postMessage
reaches the Alerts screen’s onMessage handler, then remove test.skip from “Show
Alert button triggers the in-app alert” to re-enable the regression test.
In @.circleci/config.yml:
- Line 32: Update the release job to invoke the configured ci:publish Semantic
Release command instead of npm publish, ensuring Semantic Release is available
before execution so configured versioning, release notes, GitHub release, and
release commit steps run.
In `@android/src/main/java/com/reactnativecommunity/webview/RNCWebView.java`:
- Around line 399-400: Update the print flow around print() to call the
WebView’s post() directly instead of obtaining a Handler via
getHandler().post(), preserving the existing runnable behavior while safely
handling detached views.
- Around line 445-448: Update RNCWebView.requestFocus to apply the hit-test
EDIT_TEXT_TYPE gate only for touch-driven focus requests, while preserving the
superclass behavior for programmatic and directional requests. Ensure JS
requestFocus and keyboard/D-pad navigation can delegate to super.requestFocus
without requiring a prior input-field hit.
In
`@android/src/main/java/com/reactnativecommunity/webview/RNCWebViewClient.java`:
- Line 243: Update the favicon check in the WebView error callback to handle a
null result from Uri.getPath() before comparing it with "/favicon.ico", while
preserving the existing favicon early-return behavior.
- Around line 231-236: Update RNCWebViewClient’s request-based onReceivedError
and onReceivedSslError handling to share a private error-dispatch helper,
passing request.isForMainFrame() for resource errors and true for top-level SSL
errors. Ensure the helper performs the existing main-frame failure state update,
simulated finish event, and TopLoadingErrorEvent dispatch so SSL errors reach
onLoadingError.
In `@android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManager.kt`:
- Around line 636-639: Update setNewSource in RNCWebViewManager to store the
pending source on the specific RNCWebViewWrapper rather than the shared
mPendingSource manager field, and update onAfterUpdateTransaction to read and
clear that per-view state. Preserve each WebView’s source independently when
multiple instances are updated.
- Line 132: Add the missing android.webkit.URLUtil import used by
RNCWebViewManager so the existing URLUtil.guessFileName call resolves and the
file compiles.
In `@apple/RNCWebViewImpl.m`:
- Around line 766-769: Guard the PrintingHandlerName branch and its related
message-handler registration and injected window.print script with `#if`
!TARGET_OS_OSX, while leaving them enabled for iOS and Mac Catalyst. Ensure
native macOS no longer references UIPrintInteractionController, including all
printing setup in RNCWebViewImpl.
In `@example/android/app/build.gradle`:
- Line 2: Update the Kotlin plugin application in the app module to use the same
kotlin extension-presence guard as android/build.gradle, applying
org.jetbrains.kotlin.android only when the extension is not already registered
and preventing AGP 9+ configuration conflicts.
In `@example/android/gradle.properties`:
- Around line 48-49: Remove the android.builtInKotlin=false and
android.newDsl=false opt-out properties from the Gradle configuration so AGP 10
can use built-in Kotlin and its new DSL.
In `@index.d.ts`:
- Line 4: Update the WebViewTypes export in index.d.ts to include WebViewRef,
matching the existing public export from src/index.ts so TypeScript consumers
can import the type.
In `@src/WebView.macos.tsx`:
- Line 100: Update the macOS WebView component to destructure
onLoadSubResourceError and pass it into useWebViewLogic, matching the Android
component’s handler flow so native subresource loading errors reach macOS
callers.
In `@src/WebView.windows.tsx`:
- Line 82: Update WindowsWebView and its WindowsWebViewProps contract so
useWebView2 is not silently ignored: either honor false by selecting the
supported non-WebView2 renderer while preserving the true path, or explicitly
remove/deprecate the public prop with the required breaking migration. Ensure
existing callers passing useWebView2={false} do not unexpectedly receive
RCTWebView2.
In `@src/WebViewTypes.ts`:
- Around line 1188-1190: Update the WebViewRef declarations for clearFormData
and clearHistory to be optional, matching the existing optional declarations in
index.d.ts; leave clearCache unchanged.
In
`@windows/ReactNativeWebView/codegen_manual/react/components/RNCWebViewSpec/RCTWebView2.g.h`:
- Line 635: Update the AddViewComponent registration to use L"RCTWebView2"
instead of L"WebView2", matching the name registered by
NativeComponentRegistry.get and preserving Fabric component resolution.

RNCWebViewModule::shouldStartLoadWithLockIdentifier to retain the JavaScript
decision keyed by lockIdentifier, then resolve the matching pending navigation
by allowing or cancelling it according to shouldStart. Ensure each pending
navigation is resumed or cancelled exactly once, and remove its stored state
after resolution.

Minor comments:
In `@__tests__/WebView2NewArch.test.js`:
- Around line 58-60: Update each By2.nativeName assertion in
__tests__/WebView2NewArch.test.js at lines 58-60, 64-66, 96-98, 101-103, and
112-115 to await an element operation such as isDisplayed() and assert its
result is true, ensuring the named element is actually located and usable rather
than only checking that the By2 wrapper is non-null.
In `@android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManager.kt`:
- Line 653: Update the call in the WebView debugging configuration to invoke
setWebContentsDebuggingEnabled through the declaring WebView class rather than
RNCWebView, matching the existing usage near the other WebView setup code.
In `@docs/Contributing.italian.md`:
- Line 100: Update the `bun run lint` descriptions to refer to code linting
rather than running tests. In docs/Contributing.italian.md lines 100-100,
replace the Italian testing wording; make the equivalent wording change in
docs/Contributing.portuguese.md lines 97-97, preserving the existing command and
surrounding instructions.
In `@docs/Custom-iOS.md`:
- Line 238: Update the Italian translation link in the documentation list to
reference Custom-iOS.italian.md instead of Contributing.italian.md, leaving the
other translation links unchanged.
- Line 182: Update the iOS examples in docs/Custom-iOS.md at lines 182-182 and
docs/Custom-iOS.portuguese.md at lines 180-180: import WebView from
react-native-webview, while keeping requireNativeComponent and NativeModules
imported from react-native using separate imports.
In `@docs/Getting-Started.md`:
- Around line 95-99: Update the WebView2 setup steps around autolinking, WinUI
version customization, and the Microsoft.Web.WebView2 package to use Markdown
ordered-list markers (`1.`) instead of `i.`, `ii.`, and `iii.`, preserving the
existing step text.
- Line 97: Update the WinUI version guidance sentence in the Getting Started
documentation to replace the generic “here” link text with descriptive text such
as “customizing SDK versions,” while preserving the existing documentation URL
and surrounding instructions.
- Line 5: Synchronize the localized documentation with the English requirements:
for docs/Getting-Started.md lines 5-5, add the New Architecture, React Native
0.76+, iOS 15.1+, and react-native-macos 0.76+ note to
docs/Getting-Started.italian.md and docs/Getting-Started.portuguese.md; for
docs/Guide.md lines 188-188, add the Android capture and <queries>
requirement to docs/Guide.italian.md and docs/Guide.portuguese.md.
In `@docs/Guide.italian.md`:
- Line 155: Update the iOS platform headings in the guide, including the
occurrence near the referenced second location, from level-five headings to
level-four headings, and align adjacent platform headings consistently without
changing their text.
In `@docs/Guide.md`:
- Line 371: Update the Android compatibility note in Guide.md, Guide.italian.md,
and Guide.portuguese.md to qualify the JavaScript state-loss behavior as
applying to applications targeting Android N (API 24) or later, rather than all
Android applications. Keep the existing loadUrl, evaluateJavascriptWithFallback,
and addJavascriptInterface guidance unchanged.
In `@docs/README.italian.md`:
- Line 26: Update the platform-support statement in the documentation paragraph
to remove the claim that both React Native architectures are supported, while
retaining the existing support context and aligning it with the Fabric-only
statement.
In `@docs/Reference.italian.md`:
- Line 147: Update every Italian property heading backlink, including
automaticallyAdjustsScrollIndicatorInsets, to use the existing “Indice delle
Props” anchor fragment `#indice-delle-props` instead of `#props-index`, preserving
the heading text and link structure.
In `@docs/Reference.md`:
- Line 723: Update the documented default originWhitelist values from http://_
and https://_ to http://* and https://* in docs/Reference.md:723-723,
docs/Reference.italian.md:643-643, and docs/Reference.portuguese.md:634-634;
leave the surrounding originWhitelist description and examples unchanged.
- Line 1575: Fix the Android documentation link destination in docs/Reference.md
lines 1575-1575, docs/Reference.italian.md lines 1423-1423, and
docs/Reference.portuguese.md lines 1423-1423 by removing the literal apostrophes
and using a standard HTTPS Markdown destination.
In `@example/App.tsx`:
- Around line 263-267: Remove the duplicate TouchableOpacity control identified
by testID="closeKeyboard", retaining the existing closeKeyboard control near
lines 257-261 and its behavior unchanged.
In `@example/examples/OpenWindow.tsx`:
- Around line 54-56: Import ComponentProps explicitly and use it in
OpenWindow.tsx (lines 54-56), OpenWindow.windows.tsx (lines 54-56), and
Scrolling.tsx (line 32); import FunctionComponent explicitly in
WebViewInsideScrollView.tsx (line 43) so these module files do not rely on the
React UMD global.
In `@example/examples/Scrolling.tsx`:
- Line 49: Implement the Android native setter setScrollEnabled in
RNCWebViewManager so it applies the requested scrollEnabled value to the
WebView, ensuring the Scrolling example toggle changes native scrolling
behavior; alternatively remove the scrollEnabled toggle from the example if
native support is not intended.
In `@README.md`:
- Line 20: Update the “Sponsored By” heading from level three to level two so it
follows the document’s top-level “React Native WebView” heading without skipping
a level.
- Around line 44-45: Add descriptive alt text naming the corresponding
contributors to both img elements in the contributor links, ensuring screen
readers can identify each linked contributor and resolving the markdownlint
warning.
- Line 64: Correct the visible README spelling errors by changing the package
name to create-react-native-library and the heading to How To Migrate,
preserving all surrounding documentation unchanged.
- Around line 77-78: Update the README usage example’s import references to
consistently use `@dr.pogodin/react-native-webview` instead of
react-native-webview, including the preceding usage text.

Nitpick comments:
In `@android/src/main/java/com/reactnativecommunity/webview/RNCWebView.java`:
- Around line 474-485: Update the synthetic touch dispatch in the focus-reset
block to retain each MotionEvent returned by MotionEvent.obtain, dispatch it,
and recycle it afterward. Replace the no-argument Handler construction with an
explicit main Looper (or the view’s delayed-post API), preserving the
asynchronous clearFocus behavior in the Runnable.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Guard against a null path.
Uri.getPath() returns null for opaque URIs, for example data:, mailto:, or custom non-hierarchical schemes. A failed request with such a URL dereferences null here and crashes inside the WebView error callback.
🐛 Proposed fix
- if (uri.getPath().equals("/favicon.ico")) return;
+ if ("/favicon.ico".equals(uri.getPath())) return;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
mPendingSource is manager state and leaks across WebView instances.
A single view manager instance serves every mounted RNCWebView. setNewSource writes to the shared field mPendingSource, and onAfterUpdateTransaction (line 824) consumes and clears it for whichever view is processed first. With two or more WebViews updated in the same transaction, one view can load another view's source, and the second source is dropped.
Store the pending source on the view wrapper instead of on the manager.

Microsoft.UI.Xaml.Controls.WebView2 Source dependency property setting same Uri triggers navigation
💡 Result:
In the WebView2 control, setting the Source dependency property to the same URI that is already loaded does not trigger a new navigation [1][2]. This is an intentional design choice in the WebView2 SDK [1]. When the Source property is set, the control checks if the new value is different from the current value before initiating a navigation [3]. If the values match, the navigation request is ignored, meaning events like NavigationStarting and ContentLoading are not raised [1][2]. If your application requires a refresh or re-navigation to the same URI, you should use the CoreWebView2.Reload method instead [1][4]. Alternatively, if you must use the navigation API, calling the CoreWebView2.Navigate method directly may behave differently than setting the Source property, though its behavior can also be subject to changes across runtime versions (e.g., some versions may not navigate if only a URI fragment changes) [1][2]. Key takeaways: - Setting the Source property to the current URI performs no action [3][1]. - To force a refresh, call the Reload method [1][4]. - CoreWebView2.Navigate provides a direct alternative, but be aware that behavior regarding identical URIs—especially those involving fragments (#)—has evolved in newer runtime versions [2].

Microsoft WebView2 NavigateToString called with same HTML repeatedly navigation behavior official documentation
💡 Result:
When you call NavigateToString in Microsoft WebView2, the method initiates a navigation to the provided HTML content, setting the origin of the new document to about:blank [1][2][3]. Regarding repeated calls with the same HTML: 1. Navigation Behavior: Each call to NavigateToString triggers a new navigation [4][5]. While this is similar to navigating to a URI, the documentation specifies that it initiates a navigation to the htmlContent as the source for a new document [4][3]. 2. State and Cache: Because the content is provided directly as a string parameter, it is not subject to standard HTTP cache mechanisms that affect URL-based navigation [6][7]. The NavigateToString method injects the string directly into the WebView, effectively creating a new document context [8]. 3. Functional Considerations: * Size Limit: The htmlContent parameter must not exceed 2 MB. Exceeding this limit will cause the method to return an error ("Value does not fall within the expected range") [6][1]. * Resources: NavigateToString cannot resolve local relative references (like src="image.jpg") because the base URI is about:blank [8]. External web resources (http/https) are generally unaffected by the string navigation itself, though they remain subject to standard browser caching rules [9][10]. In summary, calling NavigateToString repeatedly with the same HTML will cause the WebView2 to re-process and re-render that content as a new document each time [4][3]. It does not "cache" the string navigation itself, though any external assets referenced within that HTML may be subject to standard browser cache behavior [9][10].

Guard repeated HTML navigation.
When RCTWebView2ComponentView::UpdateProps handles an unrelated prop change, it can call m_webView.NavigateToString with unchanged HTML. NavigateToString starts a new document navigation, which can reset page state. Call it only when newProps->newSource.html differs from oldProps->newSource.html.
The equal-valued WebView2.Source assignment does not start navigation, so it does not require this guard.

The new requestFocus gate blocks programmatic and keyboard focus.
requestFocus(int, Rect) now returns false for every case except a hit-test result of EDIT_TEXT_TYPE. Two flows regress:
- The JS
requestFocuscommand reachesRNCWebViewManager.requestFocus(line 755) and thenView.requestFocus(), which routes to this override. Focus is denied unless the user already tapped an input field. - Keyboard and D-pad navigation into the WebView calls this override with a direction. Focus is denied, so users who navigate without touch cannot reach WebView content.
Restrict the gate to the touch-driven case only, and keep the default behavior for explicit and directional focus requests.

site:developer.android.com/reference/android/webkit/WebViewClient onReceivedError WebResourceRequest onReceivedSslError deprecated onReceivedError
💡 Result:
In Android development, the original onReceivedError(WebView, int, String, String) method was deprecated in API level 23 (Android 6.0) [1]. It was replaced by the modern onReceivedError(WebView, WebResourceRequest, WebResourceError) method, which is intended to provide more detailed information regarding resource loading failures [1]. Unlike the deprecated version, which primarily focused on the main page, the new callback is invoked for any resource (such as images or iframes), making it important to minimize work performed within this method [1]. The onReceivedSslError(WebView, SslErrorHandler, SslError) method is not deprecated [1]. It remains the standard mechanism for handling SSL certificate errors encountered during resource loading [1]. Developers are advised that if they override this method, they must explicitly call either SslErrorHandler.cancel or SslErrorHandler.proceed [1]. Importantly, Android documentation warns against prompting users about SSL errors, as users are generally not equipped to make informed security decisions [1]. Additionally, for non-recoverable SSL errors, the WebView will call the modern onReceivedError method with the ERROR_FAILED_SSL_HANDSHAKE argument, rather than invoking onReceivedSslError [1].

Android WebViewClient source onReceivedError WebView int errorCode String description String failingUrl empty implementation
💡 Result:
The method onReceivedError(WebView view, int errorCode, String description, String failingUrl) is a deprecated callback in the Android WebViewClient API [1][2]. It was deprecated in API level 23 (Android 6.0 Marshmallow) and replaced by the overloaded version: onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) [1][3]. An empty implementation of the deprecated method simply overrides it without performing any actions, which is the default behavior in the Android source code [4][5]. If you are implementing this for backward compatibility and wish to maintain an empty or custom implementation across different API levels, the standard practice is to use @SuppressWarnings("deprecation") and handle both versions of the method, often redirecting the logic to a common helper method [6]. Example of an empty implementation: @Override @SuppressWarnings("deprecation") public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { super.onReceivedError(view, errorCode, description, failingUrl); // Add custom logic here or leave empty } @Override public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) { super.onReceivedError(view, request, error); // Implement logic for API 23+ } It is important to note that the newer, non-deprecated method (API 23+) is triggered for all resources (such as images and iframes), not just the main page, whereas the deprecated version was triggered primarily for the main resource [1][3]. Because of this, it is recommended to perform only the minimum necessary work within the callback to avoid performance issues [1][5].

Do not retain useWebView2 as a silent no-op.
Line 82 discards this prop, but WindowsWebViewProps still documents it as the renderer selector. The component always renders RCTWebView2. Existing callers that pass useWebView2={false} now receive a different renderer without an explicit migration or failure.
Restore the supported false-path behavior, or remove and deprecate this public prop as an explicit breaking migration.

In `@src/WebView.windows.tsx` at line 82, Update WindowsWebView and its
WindowsWebViewProps contract so useWebView2 is not silently ignored: either
honor false by selecting the supported non-WebView2 renderer while preserving
the true path, or explicitly remove/deprecate the public prop with the required
breaking migration. Ensure existing callers passing useWebView2={false} do not
unexpectedly receive RCTWebView2.

Problem
Android Gradle Plugin 9 ships built-in Kotlin support and enables it by default, so
AGP registers the
kotlinextension itself. When a library also applieskotlin-androidexplicitly, the two collide and configuration fails before anything compiles. AGP
words it two ways, both the same problem:
The apply is unconditional in this module, so on an AGP 9 project this cannot be built
at all. There is no consumer-side workaround short of patching the file — setting
android.builtInKotlin=falseproject-wide just to build one dependency is not areasonable ask, and that escape hatch is removed in AGP 10.
Change
Apply the plugin only when nothing has registered the
kotlinextension yet:Files changed:
android/build.gradleThis tests the condition that actually fails, so there is no AGP version table to
keep in sync, and it covers AGP 10 — where the
android.builtInKotlinopt-out isremoved — without a special case.
android.builtInKotlinkotlinextensionfalsetruefalseThe guard sits after
apply plugin: 'com.android.library'in every file it touches,so AGP has already registered its extensions by the time it runs. I checked that
ordering per file rather than assuming it.
What I verified, and what I did not
9.2.1 and Gradle 9.4.1:
:app:assembleDebugsucceeds both with-Pandroid.newDsl=true -Pandroid.builtInKotlin=trueand with both flags off.the flags off,
compileDebugKotlinruns from the explicitly applied plugin; withthem on the build completes without it.
Phases.CONVERSIONsyntax check.Where this came from
A sweep of 500 popular React Native libraries against the AGP 9 defaults. 152 failed
with the new DSL enabled, and 144 of those failed on exactly this collision — by
far the most common blocker. Affects
@phantom/react-native-webviewhere.The same guard shape was accepted in
RevenueCat/react-native-purchases#1934,
at that maintainer's suggestion.
