Is it possible to receive Objects from the JS side via WebView.addJavascriptInterface?

Can I receive an Object through the WebView.addJavascriptInterface interface ? something like:

public class JavaScriptInterface {
    public void method(WhatEverKindOfType param) {
        Log.i(tag, param.toString());
    }
}

( with: theView.addJavascriptInterface(new JavaScriptInterface(), "obj"); )

and in the JS, for example: obj.method(myEvent);

I obviously tried that, with Object param and String param, but they all come as null. I know I can JSON.stringify it, but this brings that circular object issue (which is solvable, I know, but I don't want to start messing with it)

Is it even possible ?

First off you should not use addJavascriptInterface if you are using PhoneGap. Please, please write a PhoneGap plugin instead. The reason you want to use our Plugin interface is that we have worked around a number of issues with addJavascriptInterface.

When you use the plugin interface you pass a JSONArray to the Java side. That supports all the basic types like int, String, boolean and of course JSONObject. It is the JSONObject that you can store more structured data.
