Summary

Nested classes
`interface`	`WebViewCompat.VisualStateCallback` Callback interface supplied to `WebViewCompat.postVisualStateCallback(WebView, long, WebViewCompat.VisualStateCallback)` for receiving notifications about the visual state.
`interface`	`WebViewCompat.WebMessageListener` This listener receives messages sent on the JavaScript object which was injected by `WebViewCompat.addWebMessageListener(WebView, String, Set, WebViewCompat.WebMessageListener)`.

Public methods
`static void`	`addWebMessageListener(WebView webView, String jsObjectName, Set<String> allowedOriginRules, WebViewCompat.WebMessageListener listener)` Adds a `WebViewCompat.WebMessageListener` to the `WebView` and injects a JavaScript object into each frame that the `WebViewCompat.WebMessageListener` will listen on.
`static WebMessagePortCompat[]`	`createWebMessageChannel(WebView webview)` Creates a message channel to communicate with JS and returns the message ports that represent the endpoints of this message channel.
`static PackageInfo`	`getCurrentWebViewPackage(Context context)` If WebView has already been loaded into the current process this method will return the package that was used to load it.
`static Uri`	`getSafeBrowsingPrivacyPolicyUrl()` Returns a URL pointing to the privacy policy for Safe Browsing reporting.
`static WebChromeClient`	`getWebChromeClient(WebView webview)` Gets the WebChromeClient.
`static WebViewClient`	`getWebViewClient(WebView webview)` Gets the WebViewClient for the WebView argument.
`static WebViewRenderProcess`	`getWebViewRenderProcess(WebView webview)` Gets the WebView renderer associated with this WebView.
`static WebViewRenderProcessClient`	`getWebViewRenderProcessClient(WebView webview)` Gets the renderer client object associated with this WebView.
`static boolean`	`isMultiProcessEnabled()` Returns true if `WebView` is running in multi process mode.
`static void`	`postVisualStateCallback(WebView webview, long requestId, WebViewCompat.VisualStateCallback callback)` Posts a `WebViewCompat.VisualStateCallback`, which will be called when the current state of the WebView is ready to be drawn.
`static void`	`postWebMessage(WebView webview, WebMessageCompat message, Uri targetOrigin)` Post a message to main frame.
`static void`	`removeWebMessageListener(WebView webview, String jsObjectName)` Removes the `WebMessageListener` associated with `jsObjectName`.
`static void`	`setSafeBrowsingAllowlist(Set<String> hosts, ValueCallback<Boolean> callback)` Configures a set of hosts (domain names/IP addresses) that are exempt from SafeBrowsing checks.
`static void`	`setSafeBrowsingWhitelist(List<String> hosts, ValueCallback<Boolean> callback)` This method is deprecated. Please use `setSafeBrowsingAllowlist(Set, ValueCallback)` instead.
`static void`	`setWebViewRenderProcessClient(WebView webview, Executor executor, WebViewRenderProcessClient webViewRenderProcessClient)` Sets the renderer client object associated with this WebView.
`static void`	`setWebViewRenderProcessClient(WebView webview, WebViewRenderProcessClient webViewRenderProcessClient)` Sets the renderer client object associated with this WebView.
`static void`	`startSafeBrowsing(Context context, ValueCallback<Boolean> callback)` Starts Safe Browsing initialization.

Public methods

addWebMessageListener

public static void addWebMessageListener (WebView webView, 
                String jsObjectName, 
                Set<String> allowedOriginRules, 
                WebViewCompat.WebMessageListener listener)

Adds a WebViewCompat.WebMessageListener to the WebView and injects a JavaScript object into each frame that the WebViewCompat.WebMessageListener will listen on.

The injected JavaScript object will be named jsObjectName in the global scope. This will inject the JavaScript object in any frame whose origin matches allowedOriginRules for every navigation after this call, and the JavaScript object will be available immediately when the page begins to load.

Each allowedOriginRules entry must follow the format SCHEME "://" [ HOSTNAME_PATTERN [ ":" PORT ] ], each part is explained in the below table:
