WebView: Uncaught ReferenceError: Android is not defined

Question

I am creating a WebView with code rather than loading via an XML layout. The webview appears to be created properly, but I am seeing the errors:

W/AwContent         


        

Answer 1

You didn't defined Android as a javascripinterface you have to write below lines

 // If your callback methods are in same class then just same class object
 webView.addJavascriptInterface(this, "Android");

Syntax of addJavascriptInterface() method

      addJavascriptInterface(Object object, String name);        
   //  1. `object` – *the Java object to inject into this WebView’s JavaScript context.*
   //  2. `name` – *the name used to expose the object in JavaScript*
