I need a web and mobile application which will work on android, iphone and windows as well.
I want to use facebook login for my apps and customer can like my page after login thats why i am using cordova to convert my web app into android app but i need to integrate facebook-like option which i didn't get in plugin.
So i implemented this using oglike
$scope.facebookLike = function() {
if($localStorage.hasOwnProperty("accessToken") === true) {
$http.post("https://graph.facebook.com/me/og.likes?access_token="+$localStorage.accessToken+"&object=https://www.facebook.com/Nxtlife-Technologies-Ltd-UK-180614345644169/?ref=br_rs");
alert("like sucessfully done");
} else {
alert("Not signed in");
$scope.facebookLogin();
}
}
Problem:
The code will not throwing any error but after success message it didin't make any changes to my page. like count is remains same.
og.likes is for Open Graph objects – external URLs, outside of Faceook.
You can not like Facebook pages by any other means than the official Like button.

i'am trying to made cordova application that need user login to (google + or Facebook)
so i show button for sign in to (google+ or Facebook)
but after i close the app and open it again i need the sign in button hide depending on last signed in account
i need to know how i can check if user signed after closing my application?
ie check if user subscribe with data login to my app or no?
You can check this when your application gets loaded in
function onDeviceReady() {
// Now safe to use device APIs
//Create small function which check for is access toke valid or not
//which returns Boolean true or false
// Else you can use localStorage.isSignInned and once logged in set it as true.
if(isSignInned)
{
//hide buttons
}
}
You can check facebook javascript api here and google javascript api here
It depends upon how you want your application to work.
I am attaching working sample which i created for Facebook for GooglePlus
hope this helps.!
I am trying to use the Grails Facebook Authentication plugin but am running into problem. I have (I believe) successfully installed the plugin, put a facebook connect control on a page, and ran the installation script.
When I click on the Facebook Connect button I am correctly brought to Facebook, where I login correctly. At this point the popup closes and nothing happens. I have a custom FacebookAuthService but no breakpoints inside ever get called. I believe I have either 1) hooked up the Service incorrectly or 2) hosed up my Facebook settings so that I am not getting the information back, but I am not sure how to diagnose the problem.
When I run the app locally, it runs on http://localhost:8080/TestApp
In my Facebook App Settings I have tried using "http://localhost", "http://localhost:8080", and "http://localhost:8080/TestApp" as the Site URL and I have "localhost" as the App Domain. What am I missing?
Here is a link to the GitHub Project (I've changed the fb private key).
Any ideas? Thanks.
Button authorize you only on client side, because of Facebook Javascript SDK. Please reload page after susseccful authization, like:
FB.getLoginStatus(function(response) {
if (typeof(response) == 'undefined') {
return
}
if (response.status == 'connected') {
window.location.reload();
}
})
The JS SDK does not currently have support for non-standard ports in this scenario, but come Tuesday, this will be corrected, and it will once again support it.
I am developing iPhone application which loads login page of my website. I am able to load my login page using phonegap/childbrowser. I am newbie to JS, Phonegap.
How do my native/phonegap application should handle logout and login event has performed on the webpage? Please guide me how to know user has logged out.
Also is it possible to add support for Push Notification in phonegap/childbrowser application ? How?
So far have seen facebook login-logout questions around but hard to understand and couldnt simulate similar approach.
does your whole app run using the childbrowser? If so why not just have the login log out as piece of your app?
Also if you have to use the childbrowser best bet is to set up a locationchange event and if the location equals a login success page then append some arguments and store those using localstorage.
example -
client_browser.onLocationChange = function(loc){
locationchange(loc);
};
function locationchange(loc){
if(loc.indexOf("http://www.example.com/success?login=true&user=foo") > -1){
var user = loc.match(/user=(.*)$/)[1]; // grab user info
localStorage.setItem('login','true'); // set login as true
localStorage.setItem('user',user); // set username
}
}
that will save to your app locally that the user is logged in and their username, which you can use later if you need to use the childbrowser by passing that in the url you open and on the server side you'll have to look for those arguments.
to log out just open the childbrowser and send a logout argument
www.example.com/logout?user=foo
and in your localStorage
localStorage.setItem('login','false');
Honestly this is kind of a vague question, it would really help to understand why you're wanting to do this in the childBrowser vs your app...
For our iPhone native application we have a URL : example://
On the iPhone if I type this URL (example://) in safari it automatically opens up my application.
From my "regular" website I have a link which when the user clicks it opens the application. The problem is that if the application is not installed on the iPhone it throws "Unable to open" error.
So before rendering the link on my "regular" site I need to check if the app is installed, one solution is to make an Ajax call and check for status code:
$.ajax({
type: 'POST',
url: 'example://',
complete: function (transport) {
if (transport.status == 200) {
alert('Success');
} else {
alert(transport.status);
alert('Failed');
}
}
});
But this code is always returning a status code "0".
Is there a way to find out from the web if the native iPhone app is installed?
If u are referring to Mobile Safari, you're out of luck. There's no documented public API that I know of that can do this. Mobile Safari is sandboxed away from the OS.
If it's in a webview within an app, u can request the URL and let the webview delegate talk to the native app / query the handling of example://. Otherwise, no way the browser can know existence of any installed app.
I have a Facebook app that is built as an iFrame. I am using the JavaScript client API loaded via:
http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php
In my initialization code, I use the requireLogin method to ensure that the user has authorized the app. I have found this to be necessary to be able to gather the user's name, avatar, etc. for the scoreboard. Here's a representative code snippet:
FB_RequireFeatures(["Connect","Api"], function() {
FB.Facebook.init("...API_KEY_HERE...", "xd_receiver.htm");
var api = FB.Facebook.apiClient;
api.requireLogin(function() {
api.users_getInfo(
FB.Connect.get_loggedInUser(),
["name", "pic_square", "profile_url"],
function(users, ex) {
/* use the data here */
});
});
});
This causes the iframe to redirect causing the Facebook authorization screen to load within my app's iFrame. This looks junky and is somewhat confusing to the user, e.g. there are two Facebook bars, etc.
Question 1: is there anything I can do to clean this up while still implementing as an iFrame, and still using the JavaScript APIs?
According to the FB API documentation:
FB.ApiClient.requireLogin
This method is deprecated - use
FB.Connect.requireSession instead.
My experience though when I replace api.requireLogin with FB.Connect.requireSession it never gets invoked. I'd prefer the recommended way of doing it but I struggled and was not able to find a way to get it to work. I tried adding various arguments for the other two parameters as well with seemingly no effect. My expectation is that this method will load in a dialog box inside my app iFrame with a similar authorization message.
Question 2: what am I missing with getting FB.Connect.requireSession to properly prompt the user for authorization?
Finally, at the end of the game, the app prompts the user for the ability to publish their score to their stream via FB.Connect.streamPublish. Which leads me to...
Question 3: am I loading the correct features? Do I need both "Api" and "Connect"? Am I missing any others?
Here is a summary of the changes I needed to make to clean up the authorization process. It appears that iFrames must fully redirect to properly authorize. I tried using the FBConnect authorization but it was a strange experience of popup windows and FBConnect buttons.
Ultimately this game me the expected experience that I've seen with other FB apps:
FB_RequireFeatures(["Connect","Api"], function() {
var apiKey = "...",
canvasUrl = "http://apps.facebook.com/...";
function authRedirect() {
// need to break out of iFrame
window.top.location.href = "http://www.facebook.com/login.php?v=1.0&api_key="+encodeURIComponent(apiKey)+"&next="+encodeURIComponent(canvasUrl)+"&canvas=";
}
FB.Facebook.init(apiKey, "xd_receiver.htm");
FB.ensureInit(function() {
FB.Connect.ifUserConnected(
function() {
var uid = FB.Connect.get_loggedInUser();
if (!uid) {
authRedirect();
return;
}
FB.Facebook.apiClient.users_getInfo(
uid,
["name", "pic_square", "profile_url"],
function(users, ex) {
/* user the data here */
});
},
authRedirect);
});
For iFrames, the solution was ultimately to redirect to the login URL which becomes the authorization URL if they are not already logged in.
I think that FB.requireSession only works from a FB connect site outside of
Facebook. If you're using an app hosted on apps.facebook.com use the php api
call instead,
$facebook = new Facebook($appapikey, $appsecret);
$facebook->require_login();
or link to the login page.
Of these methods to login
* Using the PHP client library
* Directing users to login.php
* Including the requirelogin attribute in a link or form
* Using FBML
only the first 2 are available to iframe apps hosted on apps.facebook.com
I think requirelogin and fbml only work with fbml canvas apps.

Question 1: is there anything I can do
to clean this up while still
implementing as an iFrame, and still
using the JavaScript APIs?
Question 2: what am I missing with
getting FB.Connect.requireSession to
properly prompt the user for
authorization?
Please have a look at this. This article discusses correct use of require session and provides links on how to implement that. And yes, you are right, the requireLogin has been deprecated and won't help any more.
Question 3: am I loading the correct
features? Do I need both "Api" and
"Connect"? Am I missing any others?
As far as I know, you can use both API and Connect together, basically you access Facebook's API with the help of JavaScript.
For iframe apps however, there is no great help and minimum support of API with some handful functionality available. See this for more info.
This causes the iframe to redirect
causing the Facebook authorization
screen to load within my app's iFrame.
This looks junky and is somewhat
confusing to the user, e.g. there are
two Facebook bars, etc.
Finally and personally I have not seen any iframe app requiring user to add the app first. This will create the problem of two bars you mentioned as quoted above.
The link I posted at the beginning of my answer has some useful links to get you started and decide the next-steps or possibly making changes to your apps.
