I have built an app using titanium alloy
index.js
// Use the Alloy.Globals.Facebook namespace to make Facebook module API calls
var facebookModule = Alloy.Globals.Facebook;
//set facebook app id
facebookModule.appid = Ti.App.Properties.getString("ti.facebook.appid");
//set permissions i.e what data I want
facebookModule.permissions = ['user_friends','user_photos'];
// Do not force a facebook html popover but use the native dialog if possible
facebookModule.forceDialogAuth = false;
//invoke method onto button from module
$.fbButton.style = facebookModule.BUTTON_STYLE_WIDE;
$.index.open();
In my index.js controller I have this segment of code, it executes and I am presented with a log in screen.
I then fall into 2 problems:
1) "FB Session: Should only be used from a single thread"
2) I am unable to get the access token.
Not sure how to resolve both as the inbuilt login function has it's own event handler.
Cheers
Like you said, the inbuilt login function does have it's own handler.. so you should listen for event changes, something like this:
facebookModule.addEventListener('login', function(e) {
if (e.success) {
Ti.App.Properties.setString('face_token', facebookModule.getAccessToken());
// DO SOMETHING WITH THE TOKEN - open new window, auth the user...
}
});
If you try to get the access token BEFORE the login event is fired, you'll end up bad.
Now about the single thread thing.. I did run into this a while back.. I'm not sure exactly what I did to solve it, but I think it might be related to opening multiple windows or event allowing more than one call to the facebook API. Try to check if you are closing your windows and if the login function is being called more than once.
Let me know if that works for you. Good luck.

Is it possible to change the URL for $location in AngularJS within an Electon app but without implicitly loading that URL? The problem is that Electron is loading index.html (and other resources) locally, which is intended. But then of course it also sets $location to the local file system.
Background: The reason why I need $location to point to the server is that there is some existing legacy code (which I must not change) and this code uses e.g. $location.search. So after the Electron app has started I'd need to set the location correctly, so that this legacy code can work.
UPDATE 17.07.2020
Here is the requested example code:
I'm trying to set the location with window.location = "https://example.com?param1=test" so that the AngularJS function $location.search() returns param1=test. The problem is, as mentioned above, that when setting window.location, Electron loads the index.html from that server and replaces the content of the BrowserWindow. But I want to load those resources (index.html, *.js, *.css locally) I also tried:
window.location.href = ...
window.location.assign (...)
window.location.replace (...)
but all of these are reloading the page as well.
I think you'll want to add an event listener for will-navigate. Docs can be found here. The important piece:
[The will-event event will be] emitted when a user or the page wants to start navigation. It can happen when the window.location object is changed or a user clicks a link in the page.
I'd imagine your main.js file will look something like this, it's bare-bones but I hope you get the idea.
const {
app
} = require("electron");
let window;
function createWindow(){
window = new BrowserWindow(){...};
// etc....
}
app.on("ready", createWindow);
// For all BrowserWindows you make, the inner bindings will be applied to each;
// more information for "web-contents-created" is here: https://www.electronjs.org/docs/api/app#event-web-contents-created
app.on("web-contents-created", (event, contents) => {
contents.on("will-redirect", (event, navigationUrl) => {
// prevent the window from changing path via "window.location = '....'"
event.preventDefault();
return;
});
});
FYI: This event listener is mainly used for security reasons, but I don't see why you can't use it in your case.
Im implementing auth using this and am currently showing a loading icon in React when a user clicks the button to sign in and the auth2 account selection/login window shows.
However if a user closes the window, there doesnt seem to be any event fired i.e the signIn() function which returns a promise never resolves, I would have thought google would return an error for this promise if the window is closed. As a result there is no way for me to stop showing the loader icon and reshow the login menu.
I was wondering if anyone had a solution for this?
I try to modifiy my code that call Google OAuth 2.0 window.
You only have to add extra AJAX method that cover what is Google OAuth error result.
gapi.auth2.getAuthInstance().signIn()
Change it to this one,
gapi.auth2.getAuthInstance().signIn().then(function(response){
//If Google OAuth 2 works fine
console.log(response);
}, function(error){
//If Google OAuth 2 occured error
console.log(error);
if(error.error === 'popup_closed_by_user'){
alert('Oh Dude, Why you close authentication user window...!');
}
});
That's it...
For more detail about Google OAuth 2.0 information, you can visit this link.
https://developers.google.com/api-client-library/javascript/samples/samples#authorizing-and-making-authorized-requests
Sample code on JavaScript:
https://github.com/google/google-api-javascript-client/blob/master/samples/authSample.html
Although the API provides a mechanism for detecting when the user clicks the Deny button, there is not a built-in way for detecting that the user abruptly closed the popup window (or exited their web browser, shut down their computer, and so on). The Deny condition is provided in case you want to re-prompt the user with reduced scopes (e.g. you requested "email" but only need profile and will let the user proceed without giving you their email).
If the response from the sign-in callback contains the error, access_denied, it indicates the user clicked the deny button:
function onSignInCallback(authResult) {
if (authResult['error'] && authResult['error'] == 'access_denied') {
// User explicitly denied this application's requested scopes
}
}
You should be able to implement sign-in without detecting whether the window was closed; this is demonstrated in virtually all of the Google+ sample apps. In short, you should avoid using a spinner as you're doing and instead should hide authenticated UI until the user has successfully signed in.
It's not recommended you do this, but to implement detection of the pop-up closing, you could do something like override the global window.open call, then detect in window.unload or poll whether the window was closed without the user authenticating:
var lastOpenedWindow = undefined;
window.open = function (open) {
return function (url, name, features) {
// set name if missing here
name = name || "default_window_name";
lastOpenedWindow = open.call(window, url, name, features);
return lastOpenedWindow;
};
}(window.open);
var intervalHandle = undefined;
function detectClose() {
intervalHandle = setInterval(function(){
if (lastOpenedWindow && lastOpenedWindow.closed) {
// TODO: check user was !authenticated
console.log("Why did the window close without auth?");
window.clearInterval(intervalHandle);
}
}, 500);
}
Note that as I've implemented it, this mechanism is unreliable and subject to race conditions.
I would like to create a custom plugin for tracking events in my JavaScript Application using Google Analytics Measurement Tool (GA MT), but I am a newbie and not sure how to write such plugin.
My idea about the plugin:
it should have defined all types of events I am going to track (i.e. starting of an application, button clicked, 1st, 2nd, ... slide entered, etc)
if I understand how GA MT works correctly, I will need to specify an event hit for each custom event (see more)
part of the hit parameters (url) is shared (such as version, client ID, tracking ID...)
the other part of the url is custom, so I will store the differences in various functions inside of the plugin
these functions will be later called i.e. on button clicked, on goToNextSlide etc, which will send a hit to GA.
This is an example of my plugin:
(function( $ ) {
var $_document = $(document);
// Shared hit parameters
var hit = 'https://www.google-analytics.com/collect?';
hit += 'v=1'; // Version.
hit += '&t=pageview'; // Pageview hit type.
hit += '&tid=UA-XXXXXX-Y'; // Tracking ID / Property ID.
hit += '&cid=555'; // Client ID.
/* Application opened */
function gacAppOpened() {
console.log('gacAppOpened');
hit += '&dp=%2Fslide-1'; // Page.
httpGetRequest(hit);
}
/* Slide-2 entered */
function gacSlide2() {
console.log('gacSlide2');
hit += '&dp=%2Fslide-2'; // Page.
httpGetRequest(hit);
}
function httpGetRequest( theUrl )
{
var req = new XMLHttpRequest();
req.open("POST", theUrl, true);
req.send(null);
}
}( jQuery ));
This is how I load the plugin (gaCustom.js) and my common JS file (app.js)
<script src="js/gaCustom.js"></script>
<script src="js/app.js"></script>
When trying to reach to my function from inside app.js, I got error (not a function)
goToDefault: function() { // loads first page of my app,
// a hit should be sent to GA about app started
...
gacAppOpened();
... // render template
},
So I am wrong somehow in defining the plugin and using it. I also tried few other attempts, but all of them failed.
I would appreciate to hear whether my approach is good or wrong and what to improve as I am a newbie and would like to do this correctly.
I'm wrapping a web app in a Windows Store app shell using a x-ms-webview. This works fine, but I have one problem. I use PayPal and since PayPal doesn't allow to be iframed I need to open PayPal in a new browser window.
On regular browsers this isn't a problem. The window open and when the user returns from PayPal I can a callback on "opener" and update the users account.
But when doing this in a Windows Store app the window.open triggers IE to launch. The problem is to return to my app and let it know that the user finished the transaction.
My first idea was just to use a URI activation. This kind of works, but I having trouble knowing if the PayPal page was launch from a regular browser or an app. I also think it is confusing for the user to be taken to another app to make the purchase.
I would prefer to have the window open in my app, but I'm not sure how I would open open a new x-ms-webview as a modal window overlapping existing webview.
What is the best way to communicate from the current web view and the app?
Can I use postMessage to send messages between the app and the x-ms-webview even though the src of the web view is a http hosted site?
Thank you for your help.
I found a solution to this.
First, you will need to use a https url for the embedded site. The reason for this is that the solution include postMessage and invokeScriptAsync.
First, my markup in my app looks something like this to have one webview for the app and one web view for the PayPal popup.
<x-ms-webview id="webview" src="https://myapp"></x-ms-webview>
<div id="paypalContainer">
<div class="paypal-header"><button id="paypalClose" type="reset">Close</button></div>
<div class="paypal-body"><x-ms-webview id="paypalWebView" src="about:blank"></x-ms-webview></div>
</div>
Then, when the web app is ready to use PayPal, I use window.external.notify to send a message to the Windows Store app.
if (window.external && 'notify' in window.external) {
window.external.notify(JSON.stringify({ action: 'paypal' }));
}
The windows store app listens for Script Notify events and displays the paypalWebView.
webview.addEventListener("MSWebViewScriptNotify", scriptNotify);
function scriptNotify(e) {
var data = JSON.parse(e.value);
if (data.action === "paypal") {
var loading = document.getElementById("loading-indicator");
var container = document.getElementById("paypalContainer");
var paypalWebView = document.getElementById("paypalWebView");
var paypalClose = document.getElementById("paypalClose");
if (paypalWebView.src === "about:blank") {
paypalWebView.addEventListener('MSWebViewNavigationCompleted', function (e) {
loading.classList.remove('loading');
var successUrl = '/paypal/success';
if (event.target.src.indexOf(successUrl) !== -1) {
var operation = webview.invokeScriptAsync("updateUser");
operation.oncomplete = function () {
(new Windows.UI.Popups.MessageDialog("Your account is refreshed", "")).showAsync().done();
};
operation.start();
}
});
paypalWebView.addEventListener('MSWebViewNavigationStarting', function (e) {
console.log("Started loading");
loading.classList.add('loading');
});
paypalClose.addEventListener('click', function () {
container.classList.remove("visible");
});
}
paypalWebView.src = "https://myapp/paypal/";
container.classList.add("visible");
}
}
So, basically, when the script notify event fires, I parse the sent json string to an object and check what kind of action it is. If it's the first time I run this I setup some naviation event handlers that check if the web view reach the Success page. If we have, I use incokeScriptAsync to let the web app know that we're done so it can refresh the user account the new payment.
I think you can use a similar solution for authentication and just check your your return URL after authenticating.
Hope this helps!
In my Phonegap Android app, I have the following Javascript code:
function onDeviceready()
{
window.plugins.webintent.getUri(function(url)
{
alert("WebIntent Fired Up! URL is " + url);
if (url.substring(0, 37) === "https://xxxxxxx.com/confirmation.html")
{
alert("intent matched!");
var params = url.substr(url.indexOf("?") + 1);
params = params.split("&");
var verificationData = params[0].split("=");
var emailData = params[1].split("=");
launchLinkEmail = emailData[1];
launchLinkVerification = verificationData[1];
alert("verification is " + launchLinkVerification);
alert("email is " + launchLinkEmail);
}
});
}
$(document).ready(function() {
document.addEventListener('deviceready', onDeviceready, true);
});
The problem is that the variables launchLinkVerification and launchLinkEmail seem to get set after the page is loaded and the Javascript is finishing up, and so their value is empty when I try to call it anywhere that I want to use them. The alerts always display the information I want, but if I try to display them anywhere in my HTML pages, or set conditionals based on their value, neither work.
On the other hand, it seems that if I use window.plugins.webintent.getUri(function(url) anywhere other than onDeviceready it sometimes doesn't execute at all (or at least not under conditions that I can predict or understand), and again the variables don't get set.
Ultmately, what I want to do is:
Get the data from the URL that WebIntent captures.
If the data from WebIntent matches certain criteria, then switch to another page using window.location = confirmation.html
Fill two fields on the form on confirmation.html with the two variables I got from the URL that WebIntent picked up.
How do I get the data from the Webintent call, switch pages depending on what that data is, and then use that data on the new page?
I haven't used the WebIntent plugin specifically, but if I understand your description correctly, I think you're running into a problem where you're running some JavaScript in the head or maybe in the body to configure the page the way you want it. But that code is dependent upon what happens in your onDeviceready(). The call to onDeviceready() is going to be made asynchronously at anytime PhoneGap feels it is ready. Usually it is called quickly, but quickly is a relative term.
What you likely need is someway for this async code to then trigger the code you want. JQuery provides the $.Deferred() object which you might find helpful. You can setup a Deferred, you add your other code in with Deferred.done(), and when it runs onDeviceready() resolves the object which then runs the callbacks.
http://api.jquery.com/jQuery.Deferred/
I've used this to allow something like onDeviceready() to trigger a series of other behaviors in my application which I may not have wanted to structure into one big function.
