Communication between Android Java and Phonegap Javascript?

I finally made it work.

• Create a class with methods you want to use:

  publicclassMyClass{privateWebView mAppView;privateDroidGap mGap;publicMyClass(DroidGap gap,WebView view){
      mAppView = view;
      mGap = gap;}publicString getTelephoneNumber(){TelephonyManager tm =(TelephonyManager) mGap.getSystemService(Context.TELEPHONY_SERVICE);String number = tm.getLine1Number();return number;}}

• In your main activity add a Javascript interface for this class:

  publicclassMainextendsDroidGap{privateMyClass mc;@Overridepublicvoid onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);super.init();
  
          mc =newMyClass(this, appView);
          appView.addJavascriptInterface(mc,"MyCls");super.loadUrl(getString(R.string.url));}}

• In Javascript call window.MyCls methods:

  <script>
    $(function(){
      $("#phone").text("My telephone number is: "+ 
              window.MyCls.getTelephoneNumber());});</script>
