Passing a JavaScript object using addJavascriptInterface() on Android

Is it possible to pass a JavaScript object from JavaScript to Java using addJavascriptInterface()? Something along these lines:

var javaScriptObject = {"field1":"string1", "field2":"string2"};
JavaScriptInterface.passObject(javaScriptObject);

How would such a call be captured on the Java side? I have no problem setting up the interface to send a string, but when I send an object, I receive null on the Java end.

AFAIK, addJavascriptInterface() only works with primitive types and Strings, and so you cannot pass arbitrary Javascript objects.

I can run this feature

In Javascript :

var data = {
            'username' : $('#username').val().trim(),
            'password' : $('#password').val().trim(),
            'dns' : $('#dns').val().trim()
        }
        var str = JSON.stringify(data);
        Native.getLoginService(str);

In Android : 

@JavascriptInterface
public void getLoginService(String jsonData){
    try{
        JSONObject data = new JSONObject(jsonData);
        String username = data.getString("username");
        String password = data.getString("password");
        String dns = data.getString("dns");

        Log.i("TAG",username + " - " + password + " - " + dns);

    }catch (Exception ex){
        Log.i("TAG","error : " + ex);
    }
}

Good luck with...
