Android-JavascriptInterface-Sample

Call Java (Android) methods from Webview using Javascript

How To

1. Create a class named JSInterface inside any Activy or other Intent

2. Create a class with public methods with @JavascriptInterface annotations (Not @JavaScriptInterface)

       public class JSInterface {
       ...
       @JavascriptInterface
       public void toastMe(String text) {
           Toast.makeText(mContext, text, Toast.LENGTH_SHORT).show();
       }
   }

3. Attach the class name as the Webview's JavascriptInterface.

   webview.addJavascriptInterface(new JSInterface(this), "JSInterface");

4. Call JSInterface.toastMe(text) from Webview's Javascript instance

   var text = "I want to be toasted";
   JSInterface.toastMe(text);
