외부 사이트를 앱 화면(WebView)에 띄우고 있었다. 사용자에게는 모아동 헤더가 붙은 채로 뜨고 제목은 기본값 "웹페이지" 라 어느 사이트인지 알 단서가 없다. 주소창도 없다. 기술적으로 더 문제인 건 그 WebView 가 앱 프로세스 안이라는 것이다. onMessage 가 붙어 있어 외부 페이지가 window.ReactNativeWebView.postMessage 로 SUBSCRIBE_TOGGLE, NAVIGATE_WEBVIEW, OPEN_EXTERNAL_URL 을 그대로 호출할 수 있다. WebBrowser.openBrowserAsync 로 넘긴다. iOS SFSafariViewController, Android Chrome Custom Tabs 라 OS 브라우저 프로세스에서 돌고 앱 JS 에 닿지 못한다. 도메인이 표시되고 시스템 브라우저 세션을 공유한다. 새로 도입하는 방식이 아니다. 배너(banner.tsx), 동아리 SNS(useNavigator -> OPEN_EXTERNAL_URL), external-link.tsx 가 이미 같은 함수를 쓴다. slug=external 경로만 예외로 남아 있었다. 열기 실패는 로그만 남긴다. 실패해도 웹뷰 이동은 이미 취소된 상태라 조용히 아무 일도 안 일어나면 원인을 알 수 없다. router 는 이 콜백에서 더 쓰이지 않아 deps 에서 뺀다. handleMessage 의 내부 라우팅에는 그대로 쓴다.

- Around line 188-203: Update the `onShouldStartLoadWithRequest` flow in
`HomeWebView` to distinguish Android server redirects from direct user
navigations, using redirect information supplied by the native layer. Skip the
`WebBrowser.openBrowserAsync` branch for redirects so WebView handles them,
while retaining the existing external-browser behavior for direct user
navigations.

react-native-webview 13.15.0 Android onShouldStartLoadWithRequest server redirects callback contract
💡 Result:
For **`react-native-webview` 13.15.0 on Android**, `onShouldStartLoadWithRequest` is a synchronous **allow/deny decision for navigations Android reports to `shouldOverrideUrlLoading`**: return `true` to continue, `false` to block. The Android client passes the reported URL to JavaScript and waits briefly for that decision; if it times out, it defaults to allowing the navigation. ([github.com](https://github.com/react-native-webview/react-native-webview/blob/v13.15.0/docs/Reference.md))
**For server redirects:** the v13.15.0 docs explicitly say the callback is **not called for the first load**. The implementation handles Android navigation callbacks, but neither the docs nor this code guarantee a callback for every HTTP redirect hop. So don’t rely on it as a complete redirect-chain or HTTP-response interceptor; whether a particular server redirect destination triggers the callback is not established by these sources. ([github.com](https://github.com/react-native-webview/react-native-webview/blob/v13.15.0/docs/Reference.md))
If you need to recognize a redirect destination when it *is* reported, check `request.url` and return `false` to prevent that navigation. Keep it synchronous—an async callback won’t provide the native allow/deny decision in time. ([github.com](https://github.com/react-native-webview/react-native-webview/blob/v13.15.0/src/WebViewShared.tsx))

official Android WebViewClient shouldOverrideUrlLoading not called redirects
💡 Result:
The official Android docs say `shouldOverrideUrlLoading()` **can be called for an HTTP redirect**—for example, when a URL passed to `loadUrl()` redirects via HTTP 301. But it’s not called for every navigation: notably, it isn’t called for the initial navigation your app starts with `loadUrl()`. ([developer.android.com](https://developer.android.com/reference/android/webkit/WebViewClient.html?authuser=5&utm_source=openai))
If you need to inspect redirects, the API reference distinguishes `shouldInterceptRequest()`: that callback is called only for the initial resource URL, not subsequent redirect URLs. `WebResourceRequest.isRedirect()` can identify a request that resulted from a server-side redirect when you receive one. ([developer.android.com](https://developer.android.com/reference/android/webkit/WebViewClient?utm_source=openai))
So if your override isn’t firing, check whether the navigation is app-initiated, a POST request, or otherwise outside the callback’s coverage. AndroidX’s `WebViewClientCompat` docs specifically note that POST requests aren’t reported and that redirect handling depends on `SHOULD_OVERRIDE_WITH_REDIRECTS` support. ([developer.android.com](https://developer.android.com/reference/androidx/webkit/WebViewClientCompat?utm_source=openai))

github react-native-webview v13.15.0 RNCWebViewClient shouldOverrideUrlLoading onShouldStartLoadWithRequest Android source
💡 Result:
In **`react-native-webview` v13.15.0**, Android’s `RNCWebViewClient.shouldOverrideUrlLoading` works as follows:
- It creates a request event containing the URL and a `lockIdentifier`, then dispatches it to JavaScript for `onShouldStartLoadWithRequest`.
- It waits up to **250 ms** for JavaScript’s response. If no response arrives in time—or the wait is interrupted—it **allows** the navigation by returning `false`.
- Otherwise, it returns `true` when JavaScript rejects the request and `false` when it allows it.
- The `WebResourceRequest` overload extracts its URL and delegates to the string overload.
- When synchronous handling is unavailable (debugging or missing Catalyst instance), it dispatches the legacy event and returns `true`; JavaScript then handles the load through the older event-and-load path. ([github.com](https://github.com/react-native-webview/react-native-webview/blob/v13.15.0/android/src/main/java/com/reactnativecommunity/webview/RNCWebViewClient.java))
The `onShouldStartLoadWithRequest` prop is wired up in the v13.15.0 Android JS component. ([github.com](https://github.com/react-native-webview/react-native-webview/blob/v13.15.0/src/WebView.android.tsx))

Android에서 서버 리다이렉트를 사용자 이동으로 처리하지 마세요.
handleLoadEnd 이후 loaded는 true입니다. Android의 WebViewClient.shouldOverrideUrlLoading은 HTTP 리다이렉트에서도 호출될 수 있으며, react-native-webview 13.15.0은 이 URL을 onShouldStartLoadWithRequest로 전달합니다.
따라서 초기 로드가 끝난 뒤 내부 링크가 외부 HTTP(S) URL로 리다이렉트되면 현재 분기가 실행될 수 있습니다. 이 코드는 리다이렉트를 사용자 이동으로 판단하고 WebBrowser.openBrowserAsync로 열며 WebView 이동을 취소합니다. 이전처럼 WebView 내에서 처리해야 하는 서버 리다이렉트의 동작이 변경됩니다.
Android 네이티브 계층에서 리다이렉트 여부를 전달하고, 리다이렉트에는 외부 브라우저 분기를 적용하지 마세요. 직접 사용자 이동에만 현재 브라우저 열기 동작을 적용해야 합니다.
