Hi Mohanraj,

I am assuming that you are launching the SalesForceLogin page via Phonegap's InAppBrowser and once you authenticate and allow permission you want to get back to the home page. If this is your use case, here is a code that you could us for reference

You will never leave your index.html page for authentication but you would simply open a browser that loads the login page.

//on Dom Ready
$(function(){
//Listen for device ready
document.addEventListener("deviceready",onDeviceReady);
//on Device Ready
function OnDeviceReady(){
var loginURL = "https://login.salesforce.com/";
var consumerKey = '<YOUR-KEY>';
//this could be anything, once SF authentication is successful, SF will redirect your to this URL and
//your inAPPBrowser will load this
var callbackURL = 'https://login.salesforce.com/services/oauth2/success';
var client = new forcetk.Client(consumerKey, loginURL);
var authUrl = loginURL + 'services/oauth2/authorize?' + '&response_type=token&client_id=' + encodeURIComponent(consumerKey) + '&redirect_uri=' + encodeURIComponent(callbackURL);

//load the SF login page in an InAppBrowser
var authWindow = window.open(data.authUrl, "_blank", 'location=no,toolbar=no,clearsessioncache=yes');

//register a loadstop event hander on the InAppBrowser, this gets called when ever your
//inAppBrowser changes url
authWindow.addEventListener('loadstop', function(e) {
var loc = e.url;
//when url is changed check if the url contains your specific callbackURL
if (loc.search(data.callbackURL) >= 0) {
//at this point close your inapp browser
//you will land on the index page within your application.
authWindow.close();
//your code after successful authentication
}
});
}
});

Hope this helps
