Receives a message sent by a postMessage() on the injected JavaScript object.

Note that when the frame is file: or content: origin, the value of sourceOrigin is a string "null". However we highly recommend to not use file: or content: URLs, see WebViewAssetLoader for serving local content under http: or https: domain.

view: WebView	The WebView containing the frame which sent this message.
message: WebMessageCompat	The message from JavaScript.
sourceOrigin: Uri	The origin of the frame that the message is from.
