# Event Listener

The Android SDK provides event listener to listen to various events on the client app. Through these event delegates, TapTalk.io notifies the client app of events that happen on your app.

You can listen through general events from the Live Chat SDK through the **TapTalkLiveListener** class. An instance of TapTalkLiveListener will be required to initialize the Live Chat SDK. A more complete implementation will be explained in this page.
