Public methods

getInstance

Added in API level 24

 public static ServiceWorkerController getInstance ()

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.

Returns
`ServiceWorkerController`	the default ServiceWorkerController instance This value cannot be `null`.

getServiceWorkerWebSettings

Added in API level 24

 public abstract ServiceWorkerWebSettings getServiceWorkerWebSettings ()

Gets the settings for all service workers.

Returns
`ServiceWorkerWebSettings`	the current ServiceWorkerWebSettings This value cannot be `null`.

setServiceWorkerClient

Added in API level 24

 public abstract void setServiceWorkerClient (ServiceWorkerClient client)

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

Parameters
`client`	`ServiceWorkerClient`: This value may be `null`.
