WebMessagePortCompat.WebMessageCallbackCompat


abstract class WebMessagePortCompat.WebMessageCallbackCompat


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 setWebMessageCallback. In the latter case, the application should be extra careful for thread safety since WebMessagePort methods should be called on main thread.
