Public methods
shouldInterceptRequest
@WorkerThread @Nullable abstract fun shouldInterceptRequest(@NonNull request: WebResourceRequest): WebResourceResponse?
Notify the host application of a resource request and allow the application to return the data. If the return value is null
, the Service Worker will continue to load the resource as usual. Otherwise, the return response and data will be used.
Note: This method is called on a thread other than the UI thread so clients should exercise caution when accessing private data or the view system.
This method is called only if
is supported. You can check whether that flag is supported using WebViewFeature#isFeatureSupported(String)
.
