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.
