Phonegap Java call Javascript Function -

i making hello world type phonegap application android, in call javascript function native android code set text of 1 of paragraphs in app.

i have javascript function define in app's html, , want call activity once app loads up. function sets text of paragraph in app. cannot work.

here java activity code:

public class myphonegapactivity extends droidgap {      public droidgap c;     public loadinfo info;      @suppresslint("setjavascriptenabled")      @javascriptinterface     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         super.init();         c = this;         appview.getsettings().setjavascriptenabled(true);         appview.getsettings().setjavascriptcanopenwindowsautomatically(true);         appview.loadurl("file:///android_asset/www/index.html");          appview.setwebviewclient(new webviewclient() {             public void onpagefinished(webview view, string url) {                 myphonegapactivity.this.runonuithread(new runnable() {                     public void run() {                         c.sendjavascript("javascript:getmasstimes()");                     }                 });             }         });     } }

and here javascript , html code:

<!doctype html> <html> <head> <meta charset="utf-8"> <meta name="viewport"     content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"> <title>ionic seed app</title> <link href="lib/css/ionic.css" rel="stylesheet">  <link href="css/app.css" rel="stylesheet"> <link href="lib/css/mycss.css" rel="stylesheet"> <script src="lib/js/ionic.js"></script> <script src="lib/js/angular/angular.js"></script> <script src="lib/js/angular/angular-animate.js"></script> <script src="lib/js/angular/angular-sanitize.js"></script> <script src="lib/js/angular-ui/angular-ui-router.js"></script> <script src="lib/js/ionic-angular.js"></script> <script src="js/app.js"></script> <script src="js/services.js"></script> <script src="js/controllers.js"></script> <script src="http://code.jquery.com/jquery-2.1.0.js"></script> </head> <body ng-app="myapp">     <script type="text/javascript">         function getmasstimes() {             document.getelementbyid("masstimes").textcontent = "this text";         }     </script>     <div>         <header-bar title="saint david king"             class="bar bar-header bar-energized">         <h1 class="title">saint david king</h1>         </header-bar>         <br>         <content scroll="true" has-header="true" width="100%" height="100%"             id="content"> <img alt="saint david king"             src="file:///android_asset/www/img/saintdavidthekingbackground2.png"             width="100%" /> <br>         <p id="masstimes">         </p>         </content>     </div> </body> </html>
