NsdManager.ServiceInfoCallback
| android.net.nsd.NsdManager.ServiceInfoCallback

Callback to listen to service info updates.
For use with NsdManager.registerServiceInfoCallback to register, and with
NsdManager.unregisterServiceInfoCallback to stop listening.
Summary
Public methods
onServiceInfoCallbackRegistrationFailed
public abstract void onServiceInfoCallbackRegistrationFailed (int errorCode)
Reports that registering the callback failed with an error.
Called on the executor passed to NsdManager.registerServiceInfoCallback.
onServiceInfoCallbackRegistrationFailed will be called exactly once when the callback
could not be registered. No other callback will be sent in that case.
onServiceInfoCallbackUnregistered
public abstract void onServiceInfoCallbackUnregistered ()
Reports that service info updates have stopped.
Called on the executor passed to NsdManager.registerServiceInfoCallback.
A callback unregistration operation will call onServiceInfoCallbackUnregistered
once. After this, the callback may be reused.
onServiceUpdated
public abstract void onServiceUpdated (NsdServiceInfo serviceInfo)
Reports updated service info.
Called on the executor passed to NsdManager.registerServiceInfoCallback. Any
service updates will be notified via this callback until
NsdManager.unregisterServiceInfoCallback is called. This will only be called once
the service is found, so may never be called if the service is never present.

NsdServiceInfo: This value cannot be null. |
