BREAKING CHANGE:
This release introduces the `setSupportMultipleWindows` prop for Android. This sets the underlying Android WebView setting `setSupportMultipleWindows`. This prop defaults to `true` (previously `false`), and serves to mitigate the security advisory [CVE-2020-6506](https://github.com/react-native-webview/react-native-webview/security/advisories/GHSA-36j3-xxf7-4pqg).
The primary way this new behavior changes existing React Native WebView implementations on Android is that links that open in new tabs/windows (such as `<a target="_blank">`) will now prompt to open in the system browser, rather than re-using the current WebView.
If this behavior is not desirable, you can set this new prop to `false`, but be aware that this exposes your app to the security vulnerability listed above. Make sure you have read and understand the whole advisory and relevant links.
iOS & Windows are unaffected.
```jsx
<WebView
// ...
setSupportMultipleWindows={true} // default: true
/>
```
Thanks to @mrcoinbase, @kelset, and @Titozzz for their work on this.
* Update SSL error handling for Android WebView
Update SSL error handling to call onReceivedError() only on top-level navigations. This prevents iframes and other subresources from causing user-visible SSL error messages. The desired behavior is only to have top-level navigations show user-visible error messages. All other requests should be cancelled automatically with no user-visible error message.
* Update RNCWebViewManager.java
Clarify comments and add warning on blocked subresource

This solves a class of issues when the WebView loses "context"
that a subsequent page load is the same as what was attempted
to be loaded previously. This solves a bug where a HTTP redirect
in combination with history manipulations causes a user to be
stuck and prevented from going back. Since WebView requests are
allowed to happen normally, debugging the WebView and tracking
redirects and page load initiators is more accurate and easier.
This will also bypass bridge latency and provide a faster navigation.
To do this, we must lock in the shouldOverrideUrlLoading callback
and send an event to JS. Currently, this callback is ran on
the main UI thread, of which we have no control over. This is
problematic as using the bridge in most ways seems to require
the main UI thread, which will cause a deadlock. However, using
BatchedBridge for Java->JS and a synchronous method for JS->Java
doesn't cause any problems. Additionally, it's been designed so
that if WebView suddenly runs the callback on a different thread
allowing for concurrency, it will continue to work.
There is a bug in the WebView that causes a spurious call to onReceivedError
whenever you download a file.
This commit is a workaround for that bug. The idea here is to try and detect
these spurious errors and drop them before they cause problems.
This commit should be reverted once those chromium bugs are fixed.
* Ensure each mounted WebView binds their personal onMessage handler
* Changed unique ref generation to uuid
Uses `uuid` npm package.
Dashes are removed from the ref for sanity.
* Filter out extra onLoadProgress calls; add url to onLoadProgress
* remove note about onLoadProgress not having the url property in docs
* Update Reference.md
* - add focus functionality for devices without touch screen
(faced problem while developing for android TV, cause there only remote controller for device)
* Reimplement as a ref method.
* - remove redundant requestFocus
* fix(Android): WebRTC permission request (#231)
* fix(Android): Avoid unintentionally granting requests for new permissions (#231)
* ContextCompat import migrated to androidx new artifact
* RNCWebViewManager.java original format restored
Hello, in order to use react-native-webview > 6.0.2 please make your android/gradle.properties contains:
```
android.useAndroidX=true
android.enableJetifier=true
```
This enables AndroidX libraries which are the new standard.

* Add `onScroll` callback for iOS & Android
This code was mostly extracted from https://github.com/react-native-community/react-native-webview/pull/202
I tried and tried to make it work with `Animated.event`'s `useNativeDriver`, but I was unsuccessful 😢 that'll have to be done later once I understand better how Animated's native stuff is hooked up.
* fix crash for missing onScroll
* Extract WebChromeClient from an anonymous class
* Support fullscreen videos on Android
Forces landscape mode while playing.
* Use sticky immersive mode for fullscreen videos
No longer forces landscape mode as that is a problem for portrait videos - allow
the user to rotate as necessary.
Only supports KitKat or greater, and falls back to leaving the status and navigation
bars visible for lower than KitKat. This is the easiest way to prevent issues with
resizing the video during playback.
Also implement a lifecyle event listener which means if a user backgrounds the app
or locks the screen with the video fullscreen, the UI visibility is re-applied.
* Add allowsFullscreenVideo prop to control whether videos can be fullscreen on Android
Luckily, we're able to change the WebChromeClient on demand in response to prop changes
without seeming to do any harm. If you switch to disallow fullscreen, it will attempt
to close the currently fullscreened video (if there is one) so users aren't stuck.
I did notice a bug that if you go from fullscreen allowed, to fullscreen disallowed,
the fullscreen button will remain on the video. Tapping the button will have no effect.
When setting a custom font size in the Android system, an undesirable scale of the site interface in WebView occurs.
I researched that when setting the standard textZoom (100) parameter size, this undesirable effect disappears.
This can be very useful if you need to avoid the scale of content in WebView when changing the size of system fonts, or change textZoom property directly.
Example:
`
<WebView
textZoom={100}
/>
`
