How to clear AIR cache for working Facebook logout? - actionscript-3

I am developing an AIR application that is supposed to run on desktop and mobile platforms.
For most Facebook functionality, I use the official GraphAPI for Flash, version 1.8.1.
To use the app, the user must login to Facebook, this works easily by first calling FacebookMobile.init(), and if it reports that the user is not logged in, logging in like this:
var webView :StageWebView = new StageWebView();
webView.stage = stage;
webView.viewPort = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight);
FacebookMobile.login(handleLoginResult, stage, new Array(), webView);
All of this works very well, but logging out does not work as expected. Calling
FacebookMobile.logout(handleLogout);
does log out the user from Facebook, it seems, and handleLogout is always passed a true as first parameter. After this logout, when FacebookMobile.init() is called, it also correctly reports the user as not logged in. So I call the login() method from above again.
Then, the WebView opens, but closes itself immediatly, automatically logging in the user that just logged out, without showing any kind of Facebook login screen. But I want to be able to log in another user, by having to type in email and passwort.
Probably I should mention that the logging out happens when the application starts. The user can't log out himself, the application does so when starting, so that the user should be forced to login each time. Yes, this has a reason ;)
I'm sure this is some kind of caching problem, but how can I solve it with Flash/AIR?

Bit late but better than nothing right? I have seen this issue before when I was experimenting with the OAUTH api...
Found the potential solution while looking for a separate issue but with regards to caching/cookies...
This post explains what you need to do:
http://cookbooks.adobe.com/post_Cannot_logout_from_Facebook_on_Android_devices-19254.html
Basically its not a very pretty solution, but what it does is you manually delete the folders where the caching is happening.
Hope this helps.

Implementing "reallyLogout" from this answer for a similar issue worked for me:

Clear internet explorer cache & cookies, .. and it will log you out from StageWebView facebook login
UPDATE: Change also the app id from the descriptor xml file

Restart Revmob Session - If no connection and then got connected

I have an adobe AIR AS3 application for both Android and iOS. I have implemented all the necessary code with the help of revmob's great technical support team. My problem now is if the user originally was not connected to a wifi or cellular network, the session won't start, thus the banner won't show nor the video, which is normal.
The problem is, when the user switches back to connected, the banner won't show, so i'm guessing the session didn't start.
How can i keep trying to start the revmob session, depending on when the user gets connected? in other terms, how can i restart the session as soon as the user gets connected?
You can see how to create a ConnectionChecker class to check for a internet connection in this link . After creating a ConnectionChecker instance, you can call it and call the startSession method when connection is successful.
Following the link, your code will look something like this:
var checker:ConnectionChecker = new ConnectionChecker();
checker.addEventListener(ConnectionChecker.EVENT_SUCCESS, checker_success);
checker.addEventListener(ConnectionChecker.EVENT_ERROR, checker_error);
checker.check();
private function checker_success(event:Event):void {
// There is internet connection, so call startSession
revmob = new RevMob(< YOUR_APP_ID>);
}
private function checker_error(event:Event):void {
// There is no internet connection, do nothing
}

App Widget getting hijacked by Google Sound Search?

So I'm seeing some bizarre behavior in an appwidget that I wrote.
The widget itself is quite simple - it reads a few values from persistent storage and then displays them as text. Nothing fancy in the layout - just a FrameLayout root element with some Linear Layout and TextView children.
The widget has a simple configuration activity associated with it.
The bizarre behavior is that the widget will initially show "Problem Loading Widget" after the user closes the configuration activity, and then after a few seconds it shows a "Google Sound Search" button (and clicking on the button actually does launch Google Sound Search). Then, after a few more seconds, it finally shows the expected display.
I am away from my code right now, so I'll have to wait until tonight to post code snippets. However, in the meantime, can anyone provide some insight into how such a thing could happen? Has anyone else ever experienced this? How could another widget "hijack" mine?
Thanks,
-Ron
Here are some screenshots:
There are a couple of issues with your widget and there are answers to all of them (although you didn't post any code so some of my statements are based on assumptions):
"Problem loading widget": this is the default view Android uses before the widget is initialized and the layout updated. Simply add the following line to your widget xml configuration (to show a loading message instead of the problem message):
android:initialLayout="#layout/my_cool_widget_loading_message"
If the widget shows the wrong layout then you probably have an issue in the widget's onReceive method. onReceive is called for all the widgets no matter whether the broadcast is for that specific widget. Android's AppWidgetProvider filters the broadcasts by appwidget Id and dispatches to the other methods (like onUpdate).
See also: https://developer.android.com/reference/android/appwidget/AppWidgetProvider.html#onReceive(android.content.Context, android.content.Intent).
If you override onReceive (which I assume you do), you need to call through to super.onReceive(Context, Intent) to make sure your other methods don't get calls meant for other widgets.
Now for the configuration of the widget. If you follow the Google documentation then it will all work nicely. The only improvement I'd do is what my other answer that you reference suggests (https://stackoverflow.com/a/14991479/534471). This will NOT send out two broadcasts. The setResult()/finish() part does only terminate the config Activity and let Android know whether to actually add the widget or not (depending on whether the result is RESULT_CANCELED or RESULT_OK.
From your own answer I can see why your code wouldn't work. The code is:
Intent intent = new Intent();
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[] {mAppWidgetId});
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, intent);
sendBroadcast(intent);
finish();
First of all there's no need to add the appWidgetId twice, use the AppWidgetManager.EXTRA_APPWIDGET_IDS version and you're good. Second you're using the same Intent to return as a result for the Activity. AFAIK it's not documented what happens when you do set an action on that Intent but my experience with Android widgets is that you need to stick exactly to the documentation or you'll end up having strange issues (like the ones you encounter). So please use two different Intents.
Activity result:
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
Broadcast:
Intent intent = new Intent(AppWidgetManager.ACTION_APPWIDGET_UPDATE, null, this, MyWidget.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[] {mAppWidgetId});
sendBroadcast(intent);
ok, so I figured it out. Posting here in case anyone else runs into this. I think that the Android Developer docs are a little misleading here.
The problem was that in my configuration Activity, I had this code at the end:
Intent intent = new Intent();
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[] {mAppWidgetId});
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, intent);
sendBroadcast(intent);
finish();
Providing an intent with the extra EXTRA_APPWIDGET_ID is recommended by the documentation provided by google.
However, that same document says that you have to update the widget's view by creating a RemoteView and calling AppWidgetManager.updateAppWidget() like so:
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.example_appwidget);
appWidgetManager.updateAppWidget(mAppWidgetId, views);
I didn't like the idea of placing the presentation logic in both the configuration activity and the widget class, so I instead decided to broadcast an intent at the end of the configuration activity to tell the widget to redraw itself. That's why I have setResult() AND sendBroadcast() at the end of the activity. The documentation further states that the onUpdate() callback will not be called when using a configuration activity. So this seemed neccessary. I added the ACTION_APPWIDGET_UPDATE and the EXTRA_APPWIDGET_IDS to the intent so that it would trigger the onUpdate() method. This practice was recommended by this SO answer (albeit without being included in the activity result intent - but I tried separating the two and it had no effect).
Now I'm not certain exactly how the "Google Sound Search" widget got in there, nor do I fully understand the mechanics of how the intents interacted to produce the observed results. However, as soon as I replaced my code above with the code stated in the docs, the widget was updated properly.
Intent resultIntent = new Intent();
resultIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultIntent);
finish();
This seems to contradict the documentation's statement that the configuration activity must update the widget's view. Simply providing the configuration activity result as below triggers the onUpdate() method in the widget, thus allowing the widget to redraw itself. I confirmed the behavior on an emulator running API 23 and also on a Samsung device running Samsung's android flavor.

Flash UrlLoader - prevent or suppress authentication dialog box

I have a rssfeed application made in Adobe AIR. It uses the UrlLoader to read the feeds. I need the application to never prompt the user to enter password for a website or accept a certificate of a website if is no longer valid. I prefer to have it fail instead.
I have setup the event listeners for IO+Error and Security_ERROR but that is not enough
Sample urls(this may not work in future)
http://www.dawnanddrew.com/rss2.xml (asks for user and pass atm)
I had another issue with a feed that even if it was a http url the website redirected the loader to https and then the certificate validation failed and the user was asked to accept the certificate. I need this to fail (I mark failed feeds and the user can check them when they want to find the issue and fix them or remove them)
Using AIR (which you are), you can actually tell the application to NOT handle authentication.
var request:URLRequest =new URLRequest("http://www.dawnanddrew.com/rss2.xml");
request.authenticate = false; //default is true, so you need to tell your request to not handle authentication
Then it will fail with an IO error instead of prompting for credentials.
Documentation
Note however, this will only work in AIR and is not a supported property for flash player.
You cannot do it this way. Now, the server returns specific status and the browser reacts to it by showing you a login dialog box. You cannot do this directly in flash and you cannot get default login button. You need to implement this by your own. The perfect way to do so is to check (server side) if the user is logged in and if not - return status ok (200) with an error message (let's say JSON). This specific message would be read by the flash client and a login screen would be shown (custom made). You will also need to implement the login feature by yourself :)
Sorry for the bad news, but this is the way it is with flash.

Windows Phone Custom URI

in my windows phone 8 application i am using custom uri association to launch another application through my phone.
i.e
await Windows.System.Launcher.LaunchUriAsync(new Uri("sixtag:"));
but my app is not able to get certified for store because of this. the testing team tells that you app terminates unexpectedly while executing this.
now, i don't know how to deal with this.
is there any way to throw exception if the app which i am launching is not installed on phone ?
or i should try something else so my task gets accomplished and app gets certified for store as well.
You do not need to wrap your launch in try/catch or check for success as described in the other answers. As soon as you call LaunchUriAsync, the platform takes over and will automatically handle the possibility of no app being installed by asking the user if she wishes to search in the store.
A couple of things to double-check:
1) Ensure that you can successfully back into your app following the navigation to sixtag.
2) Ensure that your call to LaunchUriAsync is the direct result of a user action (eg. tapping a button)
try
{
await Windows.System.Launcher.LaunchUriAsync(new Uri("sixtag:"));
}
catch
{
MessageBox.Show("please install Sixtag from the app store","AppMissing", MessageBoxButton.OK);
}
you can perhaps display another button and on clicking directly navigate to the app store. See if this solves your problem. Do vote it up if it does :)
You are needed to handle that as shown here . Also Read out Remarks given there.

FaceboookDesktop user stays logged in after I call FaceboookDesktop.logout

Having the same issue as this user
As3 Graph API Logout
and this user
Facebook Kiosk Logout
Using the AS3 FacebookDesktop SDK for an AIR desktop based kiosk application
http://facebook-actionscript-api.googlecode.com/svn/release/current/docs/com/facebook/graph/FacebookDesktop.html
I can login, upload successfully.
Additionally when I call
FacebookDesktop.logout(handleLogout, APP_ORIGIN)
the response object returned in handleLogout = success
I have also defined APP_ORIGIN to = the same url associated with my APP_ID.
and set FacebookDesktop.manageSession = false
The problem is the user stays logged in after I upload and I need to log them out automatically after each upload.
This solution suggests targeting logout.php passing the ACCESS TOKEN.
https://stackoverflow.com/questions/7771821/log-out-from-facebook
But I don't have an access token, only a user ID.
Can anyone suggest a solution that works with an AIR desktop application?
see this thread
https://code.google.com/p/facebook-actionscript-api/issues/detail?id=206
'I had this problem and i solved using this workaround, you have to
download the source code of the 1.7 dist. Then open the
FacebookDesktop.as file and look for the logout function (not the
static one), then find the value 'params.next =
"http://static.ak.fbcdn.net/connect/xd_proxy.php#origin="+(appOrigin?appOrigin:"")'
and change it to 'params.next = "http://www.facebook.com/"'.
