Answer 1

You have to annotate (@JavascriptInterface) methods in Java class that you want to make available to JavaScript.

    public class JavaScriptInterface {
Context context;


JavaScriptInterface(Context c) {
    context = c;
}

@JavascriptInterface
public void edit(String postid) {
    Log.d("myApp", "EDIT!");
    //do stuff
}    }

Its worked for me. Try out this.

From the Android 4.2 documentation:

Caution: If you've set your targetSdkVersion to 17 or higher, you must add the @JavascriptInterface annotation to any method that you want available your web page code (the method must also be public). If you do not provide the annotation, then the method will not accessible by your web page when running on Android 4.2 or higher.
