request cannot be fulfilled (whether or not a timeout was specified).
[Android.Runtime.Register("onUnavailable", "()V", "GetOnUnavailableHandler", ApiSince=26)]

Remarks
If the callback was registered with one of the requestNetwork methods, this will be called if no network is found within the timeout specified in #requestNetwork(NetworkRequest, NetworkCallback, int) call or if the requested network request cannot be fulfilled (whether or not a timeout was specified).
If the callback was registered when reserving a network, this method indicates that the reservation is removed. It can be called when the reservation is requested, because the system could not satisfy the reservation, or after the reserved network connects.
When this callback is invoked the associated NetworkRequest will have already been removed and released, as if #unregisterNetworkCallback(NetworkCallback) had been called.
