Yeah, I miss this method greatly in Android ;)

To execute JavaScript and get response you can do as follows:

  1. Define JavaScript callback interface in your code:

    class MyJavaScriptInterface {
        @JavascriptInterface
        public void someCallback(String jsResult) {
             // your code...
        }
    }
    
  2. Attach this callback to your WebView

    MyJavaScriptInterface javaInterface = new MyJavaScriptInterface();
    yourWebView.addJavascriptInterface(javaInterface, "HTMLOUT");
    
  3. Run your JavaScript calling window.HTMLOUT.someCallback from the script:

    yourWebView.loadUrl("javascript:( function () { var resultSrc = document.getElementById("image").getAttribute("src"); window.HTMLOUT.someCallback(resultSrc); } ) ()");
    

Hope this helps!
