Public methods

getInstance

@NonNull open static fun getInstance(): ServiceWorkerControllerCompat

Returns the default ServiceWorkerController instance. At present there is only one ServiceWorkerController instance for all WebView instances, however this restriction may be relaxed in the future.

This method should only be called if WebViewFeature#isFeatureSupported(String) returns true for WebViewFeature#SERVICE_WORKER_BASIC_USAGE.

Return
`ServiceWorkerControllerCompat`	the default ServiceWorkerController instance

getServiceWorkerWebSettings

@NonNull abstract fun getServiceWorkerWebSettings(): ServiceWorkerWebSettingsCompat

Gets the settings for all service workers.

Return
`ServiceWorkerWebSettingsCompat`	the current `ServiceWorkerWebSettingsCompat`

setServiceWorkerClient

abstract fun setServiceWorkerClient(@Nullable client: ServiceWorkerClientCompat?): Unit

Sets the client to capture service worker related callbacks. A ServiceWorkerClientCompat should be set before any service workers are active, e.g. a safe place is before any WebView instances are created or pages loaded.
