i am able to use java function from my phonegap java script function and android 2.2
but same code is not run on API 17. what should i have to do to call native java code on from java script in API 17.

i use this code in my java file

 objCustomNativeAccess = new CustomNativeAccess(this, appView);

            appView.addJavascriptInterface(objCustomNativeAccess,

                    CustomNativeAccess);

    super.loadUrl(file:///android_asset/www/index.html);

my CustomNativeAccess class is

public class CustomNativeAccess {

        private WebView mAppView;

        private DroidGap mGap;



        /**

         * Constructor

         * 

         * @param gap

         * @param view

         */

        public CustomNativeAccess(DroidGap gap, WebView view) {

            mAppView = view;

            mGap = gap;

        }



        /**

         * Get the device phone number

         * 

         * @return

         */

        public JSONObject login(String email, String password) {

            JSONObject object = new JSONObject();

                    object.put(Login_Status, login_status);

            object.put(date, dateString);

            return object;

        }

and in my java script i use this line to call this login function

 var value = window.CustomNativeAccess.login(email,pass);

so using this i successfully call this on api 2.2 but when i run this code on api 17 it give me error

Uncaught TypeError: Object [object Object] has no method 'login' at file:///android_asset/www/index.html:81

how i can i use this on api 17
