Cross-platform asynchronous calls between Android and JS, and androidjs asynchronous calls

WebView settings

WebSettings mWebSettings = getSettings();

MWebSettings. setdefatextextencodingname ("UTF-8"); // sets the default display Encoding

MWebSettings. setJavaScriptEnabled (true); // call the JS method. The Android version is later than 17, and the annotation @ JavascriptInterface is added.
