Cookies not working on mobile browsers (using ASP.NET MVC )

I have an ASP.NET C# MVC4 Web site that I have working wonderfully for the most part. However, when we tested on mobile, the cookies that I am using for authentication would not work. I set the Auth cookie in my controller action but when trying to access them on the next call they are not there. Once again this is ONLY A PROBLEM ON MOBILE. Works fine in desktop versions of IE, Chrome and Firefox. Does not work with Chrome on Android.
Code to write cookie (in controller action):
//Set information into object that can be read out of the cookie later
FormsAuthModel UserDataObj = new FormsAuthModel
{
UserID = dmUser.ID,
PasswordChange = dmUser.PasswordChange
};
string UserData = Convert.ToBase64String(clsShared.Serialize(UserDataObj));
//Create the ticket
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, dmUser.UserName, DateTime.Now, DateTime.Now.AddDays(1), false, UserData, FormsAuthentication.FormsCookiePath);
// Encrypt the ticket
string encTicket = FormsAuthentication.Encrypt(ticket);
// Create the cookie
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
System.Web.HttpContext.Current.Response.Cookies.Add(cookie);
Code to read cookie (in Global.asax.cs - Application_PostAuthenticateRequest):
HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
if (authCookie != null)
{
try
{
FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
UserDataObj = (FormsAuthModel)clsShared.Deserialize(Convert.FromBase64String(authTicket.UserData), typeof(FormsAuthModel));
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
//WriteEvent(string.Format("Error deserializing auth ticket - {0}", ex.Message), EventLogEntryType.Error);
}
}
The AuthCookie is always null on the subsequent requests. What the user sees is a login screen, they fill it out and they get redirected right back to the login screen.
I could not find anything in my searches that helped explain why all the mobile requests (my phone, my tablet and other users' phones) would act differently than the desktop browsers.
Any help would be greatly appreciated.
Thanks!!

OK I found a solution although I am not sure why. I changed the cookie creation code as follows and it worked.
//Set information into object that can be read out of the cookie later
FormsAuthModel UserDataObj = new FormsAuthModel
{
UserID = dmUser.ID,
PasswordChange = dmUser.PasswordChange
};
string UserData = Convert.ToBase64String(clsShared.Serialize(UserDataObj));
//Create the ticket
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, dmUser.UserName, DateTime.Now, DateTime.Now.AddDays(1), false, UserData, FormsAuthentication.FormsCookiePath);
// Encrypt the ticket
string encTicket = FormsAuthentication.Encrypt(ticket);
// Create the cookie - FIX IS HERE!!!
Response.Cookies[FormsAuthentication.FormsCookieName].Value = encTicket;
//HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
//Response.Cookies.Add(cookie);
Notice that the only change is in adding the cookie by setting the value directly instead of creating a cookie object and adding that to the collection.
i.e. - Response.Cookies["Name"] = Value;
I got the idea from this MS article: https://msdn.microsoft.com/en-us/library/ms178194.aspx.
So does anyone know why this would make a difference? I have used the cookie instance method several times before and never had this problem.

Titanium Appcelerator image upload issue When call service without image

I have prepared an application with image upload. It sends some text and an image.
It's working fine when I add an image and content(text). Unfortunately it's not working when I call the service without an image, see code below,
var params = {
file :$.selectedImageVw.image, //if file is not selected it will send as null
UserId : Ti.App.userID,
postContent : $.postMessage.value
};
var xhr = Titanium.Network.createHTTPClient();
xhr.onreadystatechange = function() {
if (this.readyState == 4) {
progressVw.hide();
// callback("Success");
// alert(this.responseData);
progressVw.hide();
xhr = null;
}
};
xhr.setRequestHeader('Content-Type', 'multipart/form-data');
xhr.setRequestHeader('enctype', 'multipart/form-data');
xhr.setRequestHeader('Content-length', params.length);
xhr.open("POST", "uploadUrl");
xhr.send(params);
I hope someone can help me.
Thanks in advance!!

Try to use a service like http://requestb.in/ to check if the requests made by the client are the issue or the backend you use.

#FokkeZandbergan thanks for your respone,
This issue resolve by very simple modification'
xhr.setRequestHeader('Content-Type', 'multipart/form-data');
changed to
xhr.setRequestHeader('Content-Type', "application/x-www-form-urlencoded");
Now its working with both imags and without images.
It may help to some one . :)

soomla : cocos2dx : Profile -> "ProviderNotFoundException" (cocos2d3.x)

I don't understand why Profile always return error : "ProviderNotFoundException". I followed pre-comipiled integration instructions, and I use latest versions on github for soomla-cocos2dx-core,cocos2dx-profile and cocos2dx-store.
Here is an example done with cocos2dx v3.5 (same behaviour on 3.4):
soomla::CCError *profileError = nullptr;
bool isLoggedIn = soomla::CCSoomlaProfile::getInstance()->isLoggedIn(soomla::TWITTER, &profileError);
if (profileError)
MessageBox(profileError->getInfo(), "Error");
else
CCLOG("logged in TWITTER: %d",isLoggedIn);
Application compiles successfully but that code throws a MessageBox saying "ProviderNotFoundException".
In AppDelegate.cpp here is the init I do from applicationDidFinishLaunching:
#define NEWSTRING(s) __String::create(s)
SOOMLA_STORE_EVENTS = new TSoomlaStoreEvents(); // My defined store events
PRODUCTSFORSALE = TItemsForSale::create(); //class for buy items
STOREITEMS = __Dictionary::create();
soomla::CCSoomla::initialize(SOOMLA_CUSTOM_SECRET);//"customSecret");
STOREITEMS->setObject(NEWSTRING(SOOMLA_ANDROID_PUBLIC_KEY), "androidPublicKey");
STOREITEMS->setObject(Bool::create(true), "SSV");
soomla::CCSoomlaStore::initialize(PRODUCTSFORSALE, STOREITEMS);
//----- SOOMLA PROFILE
__Dictionary *profileParams = __Dictionary::create();
__Dictionary *twitterParams = __Dictionary::create();
__Dictionary *googleParams = __Dictionary::create();
twitterParams->setObject(NEWSTRING(SOOMLA_TWITTER_CONSUMER_KEY), "consumerKey");
twitterParams->setObject(NEWSTRING(SOOMLA_TWITTER_CONSUMER_SECRET), "consumerSecret");
googleParams->setObject( NEWSTRING(SOOMLA_GOOGLE_CLIENTID), "clientId");
profileParams->setObject(twitterParams, soomla::CCUserProfileUtils::providerEnumToString(soomla::TWITTER)->getCString());
profileParams->setObject(googleParams, soomla::CCUserProfileUtils::providerEnumToString(soomla::GOOGLE)->getCString());
soomla::CCSoomlaProfile::initialize(profileParams);
Can you help me going further with Profile, please?

this is not an answer, but you might be able to glean something from here: http://answers.soom.la/t/resolved-twitter-providernotfoundexception/675/6
and here: http://answers.soom.la/t/resolved-exception-with-cocos2d-x-profile/1572

As I understand they use reflection in order to load providers (
https://github.com/soomla/ios-profile/blob/9e887f07e0d7f1acb680e02c593a8ce485c93252/SoomlaiOSProfile/ProviderLoader.m#L43). Maybe those classed just have not been loaded.
You can try to use "-ObjC" linker flag, or something like that.

How to acces shared object and display on facebook/Twitter URL Link AS3

Hey everyone so I was wondering if there is a easy method of doing this or if it can even be done without an ANE Native Extension. I picked up some code from around here and in my Flash CS6 Android AIR Application using AS3 I created two buttons on the stage one for Facebook and the other for Twitter. When the user clicks on the buttons they are redirected to the URL's and are able to post the link that I give in the vars like so:
//Share button event listener
menuEnd.share_Facebook.addEventListener(MouseEvent.CLICK, shareFacebook);
menuEnd.share_Twitter.addEventListener(MouseEvent.CLICK, shareTwitter);
private function shareTwitter(e:MouseEvent):void
{
var varsShare:URLVariables = new URLVariables();
varsShare.u = 'https://play.google.com/store/apps/details?id=air.bunnyRunner';
varsShare.t = 'Jumpy Bunny';
var urlTwitterShare:URLRequest = new URLRequest('http://twitter.com/home?status= Jumpy Bunny by Fitchett Productions: ');
urlTwitterShare.data = varsShare;
urlTwitterShare.method = URLRequestMethod.GET;
navigateToURL(urlTwitterShare, '_blank');
}
private function shareFacebook(evt:MouseEvent):void
{
var varsShare:URLVariables = new URLVariables();
varsShare.u = 'https://play.google.com/store/apps/details?id=air.bunnyRunner';
varsShare.t = 'Jumpy Bunny';
var urlFacebookShare:URLRequest = new URLRequest('http://m.facebook.com/sharer.php');
urlFacebookShare.data = varsShare;
urlFacebookShare.method = URLRequestMethod.GET;
navigateToURL(urlFacebookShare, '_blank');
}
So now I was wondering since I have sharedObject data in my game is there anyway to get that shared.data and display it on facebook when the user clicks the button it shares the data to facebook and they can post their highscore?
Thanks guys any help is appreciated.

In Android Browser link does not always execute onClick causing focus instead

I am trying to program a very standard JS behavior for a link using an HREF
onClick handler, and I am facing a strange problem caused by what I believe to be focus/touch mode behavior on Android.
Sometimes when I click on the link, instead of executing the action, it simply becomes selected/focused, with either just a focus rectangle or even also with a filled focus rectangle (selected as opposed to just focused?).
The pseudo-code right now is
go
I have tried doing something like:
go
But I still get the same pesky problem some of the time.

Try enabling Javascript on the webview.
In the activity that holds the webview, try this...
WebView wv = (WebView) findViewById(R.id.webview);
wv.getSettings().setJavaScriptEnabled(true);
I was having he same problem, but figured out it was because I did not enabled Javascript.

Try getting rid of the href attribute and see if that helps. For example, this works when viewed with the WebView component:
<p><a onClick="whereami()">Update Location</a></p>

I wonder if it's related to the onclick -- am I correct to assume that every now and then clicking any link does not follow it? To me, this seems related to the way you touch the screen (or how this is interpreted), like maybe by clicking next to the link and dragging a bit, rather than clicking on the link?
(If my assumption is correct, then this might be faulty hardware: maybe you can try on another device? Or maybe it only happens on a particular side of the link if the screen is not aligned well, and then there might be some software offset one can change?)

Try inserting this "driver" into your page code, and let us know if it works . . . It seems to be working on my site which had the same problem:
//Mouse & Touch -> Consistent Click / Mouse Commands -> Useful driver
(function() {
var isTouch = false;
var simulated_flag = 'handler_simulated';
var touch_click_array = {};
const clickMoveThreshold = 20; //Pixels
function mouseHandler(event) {
if (isTouch) {
if (!event.hasOwnProperty(simulated_flag)) {
//Unreliable mouse commands - In my opinion
var fixed = new jQuery.Event(event);
fixed.preventDefault();
fixed.stopPropagation();
}
}
else {
//Mouse commands are consistent
//TODO: generate corresponding touches
}
}
function mouseFromTouch(type, touch) {
var event = document.createEvent("MouseEvent");
event.initMouseEvent(type, true, true, window, 1, touch.screenX, touch.screenY, touch.clientX, touch.clientY
, false, false, false, false, 0, null);
event[simulated_flag] = true;
touch.target.dispatchEvent(event);
};
function touchHandler(event) {
var touches = event.changedTouches
,first = touches[0]
,type = ""
;
if (!event.hasOwnProperty(simulated_flag)) {
isTouch = true;
//Simulate mouse commands
switch (event.type) {
case "touchstart":
for (var i = 0; i < touches.length; i++) {
var touch = touches[i];
touch_click_array[touch.identifier] = { x: touch.screenX, y: touch.screenY };
}
mouseFromTouch("mousedown", first);
break;
case "touchmove":
for (var i = 0; i < touches.length; i++) {
var touch = touches[i];
var id = touch.identifier;
var data = touch_click_array[id];
if (data !== undefined) {
if (Math.abs(data.x - touch.screenX) + Math.abs(data.y - touch.screenY) > clickMoveThreshold) {
delete touch_click_array[id];
}
}
}
mouseFromTouch("mousemove", first);
break;
case "touchcancel":
//Not sure what should happen here . . .
break;
case "touchend":
mouseFromTouch("mouseup", first);
for (var i = 0; i < touches.length; i++) {
var touch = touches[i];
if (touch_click_array.hasOwnProperty(touch.identifier)) {
mouseFromTouch("click", touch);
delete touch_click_array[touch.identifier];
}
}
break;
}
}
}
document.addEventListener("mousedown", mouseHandler, true);
document.addEventListener("mousemove", mouseHandler, true);
document.addEventListener("mouseup", mouseHandler, true);
document.addEventListener("click", mouseHandler, true);
document.addEventListener("touchstart", touchHandler, true);
document.addEventListener("touchmove", touchHandler, true);
document.addEventListener("touchcancel", touchHandler, true);
document.addEventListener("touchend", touchHandler, true);
})();
Now it isn't a 100% complete script - multi-touch would probably be a little wonky, and if you built an interface depending on touch commands, it doesn't generate those in this version. But, it fixed my link-clicking problem.
Erm - ps - it's using jQuery. If you need a non-jQuery version, you can probably just remove the new jQuery.Event from the mouseHandler() function (in other words, use the original event: var fixed = event;), and I believe most browsers would be ok. I am not exactly a js compatibility expert though.
PPS - Tested with Android 1.6
PPPS - Had to modify script to allow a threshold - actual devices were having some problems with a move event being fired during the press. Probably not ideal; if anyone wants to chime in on a better way for doing that, I'd be interested in hearing...

Recently I came across exactly the same problem. I was using the onclick on a button. Sometimes it did not execute the javascript at all. The thing that worked for me was that enable the javascript before loading a url in the webview
// Enable javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
// To bind javascript code to android
mWebView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
mWebView.loadUrl(url);
