PermissionRequest


abstract class PermissionRequest
kotlin.Any
   ↳ android.webkit.PermissionRequest

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 and WebChromeClient#onPermissionRequestCanceled. Either grant() or deny() must be called in UI thread to respond to the request. New protected resources whose names are not defined here may be requested in future versions of WebView, even when running on an older Android release. To avoid unintentionally granting requests for new permissions, you should pass the specific permissions you intend to grant to grant(), and avoid writing code like this example:

permissionRequest.grant(permissionRequest.getResources())  // This is wrong!!!
  
See the WebView's release notes for information about new protected resources.
