This class defines a permission request and is used when web content requests access to protected resources. The permission request related events are delivered via WebChromeClient.OnPermissionRequest(PermissionRequest) and WebChromeClient.OnPermissionRequestCanceled(PermissionRequest). Either PermissionRequest.Grant(String[]) or PermissionRequest.Deny must be called in UI thread to respond to the request.
