# WebMessagePort.WebMessageCallback

`public static abstract class WebMessagePort.WebMessageCallback`
`extends Object` ``

java.lang.Object
↳ | android.webkit.WebMessagePort.WebMessageCallback

The listener for handling MessagePort events. The message callback methods are called on the main thread. If the embedder application wants to receive the messages on a different thread, it can do this by passing a Handler in `WebMessagePort#setWebMessageCallback(WebMessageCallback, Handler)`. In the latter case, the application should be extra careful for thread safety since WebMessagePort methods should be called on main thread.
