NewContextHubCallbackStub creates a server-side IContextHubCallback wrapping the given server implementation. The returned value satisfies IContextHubCallback and can be passed to proxy methods; its AsBinder() returns a *binder.StubBinder that is auto-registered with the binder driver on first use.

type IContextHubCallbackServer 

type IContextHubCallbackServer interface {
