WebViewClientCompat()

Compatibility version of android.webkit.WebViewClient.

Public methods

onPageCommitVisible

@UiThread open fun onPageCommitVisible(
    @NonNull view: WebView, 
    @NonNull url: String
): Unit

Notify the host application that android.webkit.WebView content left over from previous page navigations will no longer be drawn.

This callback can be used to determine the point at which it is safe to make a recycled android.webkit.WebView visible, ensuring that no stale content is shown. It is called at the earliest point at which it can be guaranteed that WebView#onDraw will no longer draw any content from previous navigations. The next draw will display either the background color of the WebView, or some of the contents of the newly loaded page.

This method is called when the body of the HTTP response has started loading, is reflected in the DOM, and will be visible in subsequent draws. This callback occurs early in the document loading process, and as such you should expect that linked resources (for example, CSS and images) may not be available.

For more fine-grained notification of visual state updates, see .

Please note that all the conditions and recommendations applicable to WebViewCompat#postVisualStateCallback also apply to this API.

This callback is only called for main frame navigations.

This method is called only if WebViewFeature#VISUAL_STATE_CALLBACK is supported. You can check whether that flag is supported using .

Parameters
`view`	WebView: The `android.webkit.WebView` for which the navigation occurred.
`url`	String: The URL corresponding to the page navigation that triggered this callback.
