  • Is there a way to use the facebook sdk with libgdx?

    - by Rudy_TM
    I have tried to use the facebook sdk in libgdx with callbacks, but it never enters the authetication listeners, so the user never is logged in, it permits the authorization for the facebook app but it never implements the authentication interfaces :( Is there a way to use it? public MyFbClass() { facebook = new Facebook(APPID); mAsyncRunner = new AsyncFacebookRunner(facebook); SessionStore.restore(facebook, this); FB.init(this, 0, facebook, this.permissions); } ///Method for init the permissions and my listener for authetication public void init(final Activity activity, final Facebook fb,final String[] permissions) { mActivity = activity; this.fb = fb; mPermissions = permissions; mHandler = new Handler(); async = new AsyncFacebookRunner(mFb); params = new Bundle(); SessionEvents.addAuthListener(auth); } ///I call the authetication process, I call it with a callback from libgdx public void facebookAction() { // TODO Auto-generated method stub fb.authenticate(); } ///It only allow the app permission, it doesnt register the events public void authenticate() { if (mFb.isSessionValid()) { SessionEvents.onLogoutBegin(); AsyncFacebookRunner asyncRunner = new AsyncFacebookRunner(mFb); asyncRunner.logout(getContext(), new LogoutRequestListener()); //SessionStore.save(this.mFb, getContext()); } else { mFb.authorize(mActivity, mPermissions,0 , new DialogListener()); } } public class SessionListener implements AuthListener, LogoutListener { @Override public void onAuthSucceed() { SessionStore.save(mFb, getContext()); } @Override public void onAuthFail(String error) { } @Override public void onLogoutBegin() { } @Override public void onLogoutFinish() { SessionStore.clear(getContext()); } } DialogListener() { @Override public void onComplete(Bundle values) { SessionEvents.onLoginSuccess(); } @Override public void onFacebookError(FacebookError error) { SessionEvents.onLoginError(error.getMessage()); } @Override public void onError(DialogError error) { SessionEvents.onLoginError(error.getMessage()); } @Override public void onCancel() { SessionEvents.onLoginError("Action Canceled"); } }

  • Microsoft Changes Developer Account Registration Requirements

    - by Tim Murphy
    Over the last couple of weeks I have noticed that Microsoft seems to have changed the requirements for Corporate accounts.  These requirements were not in effect when I originally setup the account for the company that I work for.  We also recently had our corporate account canceled without explanation and are in the process of working to get it reinstated.  This all seems to revolve around rules to increase confidence that in the producers of content.  They are now having Symantec validate a company based on legal documents. In the past there have been problems with getting credit cards accepted.  We have had to setup new Live IDs to satisfy whatever glitch the system had or unexplainable requirement.  I am hoping that in the time that has elapsed these problems have been resolved. In truth I can’t say that these new requirements weren’t always in place, but it is getting frustrating to help clients setup accounts.  I am encourage that they have taken steps to safeguard the consumer from Joe-fly-by-night, but they also need to make sure that the process doesn’t become so complex that it drives away companies from participating in the store.  We will have to keep an eye on this as things evolve. del.icio.us Tags: Windows Phone Development,Windows 8 Development,Windows Phone,Windows 8,Registration,Corporate Accounts

  • Ubuntu 11.10 won't let me login; it kicks me back to login screen

    - by zlyfire
    I was just copying files from my external HDD to my .wine directory, when I noticed the place where the launchers are (Unity desktop) was getting fuzzy and holding onto graphics from the things in the location prior(i have it autohide when a window covers it). I assumed it was just RAM problem, so I canceled the copying, since it wasn't actually important. The glitch remained, and so did another; very slow response time. The mouse moved just fine, but windows were waiting about a minute after I hit the x button to close or even switch active window. Once again, I blamed RAM (only have 2 GBs) so I restarted. Usually, it autologs me into my account, since I'm the only user, but this time it presented me with the login screen. I thought it odd, but tried to log in. A black screen with some text pops up (assuming terminal screen) for half a second then kicks me back to the login screen. I tried the guest account and no luck. I went into terminal (alt+ctrl+f1) and logged in and it worked. I deleted .Xauthority, made new account, and even rebooted quite a few times, all to no avail. Anyone have an idea?

  • Help trying/downloading ubuntu

    - by koolomwee
    I can't try ubuntu. Every time i put in my disk and press try, it shows the ubuntu sign with the dots under it than it shows a command screen basically blinking saying that it closed and canceled applications belonging to ubuntu... Than I tried to download it from the disk... same thing. Than, because I have windows, I tried to download it from the website and it worked. I rebooted my computer and went into the Ubuntu option just to find a blinking command screen again... How do I get ubuntu to work? What does happen (with the command screen) is that it shows commands that are blinking to fast for me to read the whole thing, and then it stops after like a minute or two of blinking. The only thing I do get to read is that Ubuntu commanded some applications to shut down. In the CD one it only has like 5 error messages, and when I reboot and select Ubuntu, there are over a hundred error messages. With the live-cd I have to shut down my computer to use it again. With the reboot and clicking ubuntu option it reboots by itself. I expect it to actually start up with no error messages. UPDATE I've been trying to start Ubuntu for the last couple of days, and I noticed on my last try that it said "SIGNAL 15 RECEIVED"... It also said that it's stopping Bluetooth and all other programs, and that its rebooting Maybe that'll help a little with answering my question... thanks :) this also might help: computer brand/model: HP Windows 7 Home Premium Service Pack 1, HPE240f graphics card: ATI Radeon HD 5570 I also wrote the same question here: https://answers.launchpad.net/wubi/+question/194537 might help a little more with information

  • Safe, standard way to load images in ListView on a different thread?

    - by Po
    Before making this question, I have searched and read these ones: http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview http://stackoverflow.com/questions/1409623/android-issue-with-lazy-loading-images-into-a-listview My problem is I have a ListView, where: Each row contains an ImageView, whose content is to be loaded from the internet Each row's view is recycled as in ApiDemo's List14 What I want ultimately: Load images lazily, only when the user scrolls to them Load images on different thread(s) to maintain responsiveness My current approach: In the adapter's getView() method, apart from setting up other child views, I launch a new thread that loads the Bitmap from the internet. When that loading thread finishes, it returns the Bitmap to be set on the ImageView (I do this using AsyncTask or Handler). Because I recycle ImageViews, it may be the case that I first want to set a view with Bitmap#1, then later want to set it to Bitmap#2 when the user scrolls down. Bitmap#1 may happen to take longer than Bitmap#2 to load, so it may end up overwriting Bitmap#2 on the view. I solve this by maintaining a WeakHashMap that remembers the last Bitmap I want to set for that view. Below is somewhat a pseudocode for my current approach. I've ommitted other details like caching, just to keep the thing clear. public class ImageLoader { // keeps track of the last Bitmap we want to set for this ImageView private static final WeakHashMap<ImageView, AsyncTask> assignments = new WeakHashMap<ImageView, AsyncTask>(); /** Asynchronously sets an ImageView to some Bitmap loaded from the internet */ public static void setImageAsync(final ImageView imageView, final String imageUrl) { // cancel whatever previous task AsyncTask oldTask = assignments.get(imageView); if (oldTask != null) { oldTask.cancel(true); } // prepare to launch a new task to load this new image AsyncTask<String, Integer, Bitmap> newTask = new AsyncTask<String, Integer, Bitmap>() { protected void onPreExecute() { // set ImageView to some "loading..." image } protected Bitmap doInBackground(String... urls) { return loadFromInternet(imageUrl); } protected void onPostExecute(Bitmap bitmap) { // set Bitmap if successfully loaded, or an "error" image if (bitmap != null) { imageView.setImageBitmap(bitmap); } else { imageView.setImageResource(R.drawable.error); } } }; newTask.execute(); // mark this as the latest Bitmap we want to set for this ImageView assignments.put(imageView, newTask); } /** returns (Bitmap on success | null on error) */ private Bitmap loadFromInternet(String imageUrl) {} } Problem I still have: what if the Activity gets destroyed while some images are still loading? Is there any risk when the loading thread calls back to the ImageView later, when the Activity is already destroyed? Moreover, AsyncTask has some global thread-pool underneath, so if lengthy tasks are not canceled when they're not needed anymore, I may end up wasting time loading things users don't see. My current design of keeping this thing globally is too ugly, and may eventually cause some leaks that are beyond my understanding. Instead of making ImageLoader a singleton like this, I'm thinking of actually creating separate ImageLoader objects for different Activities, then when an Activity gets destroyed, all its AsyncTask will be canceled. Is this too awkward? Anyway, I wonder if there is a safe and standard way of doing this in Android. In addition, I don't know iPhone but is there a similar problem there and do they have a standard way to do this kind of task? Many thanks.

  • Stop UIWebView from "bouncing" vertically ?

    - by Brad Parks
    Hi there; Does anyone know how to stop a UIWebView from bouncing vertically? I mean when a user touches their iphone screen, drags their finger downwards, and the webview shows a blank spot above the web page I had loaded? I've looked at the following possible solutions, but none of them worked for me: http://www.iphonedevsdk.com/forum/iphone-sdk-development/996-turn-off-scrolling-bounces-uiwebview.html http://forums.macrumors.com/showthread.php?t=619534 http://stackoverflow.com/questions/173786/how-do-i-stop-a-uiscrollview-from-bouncing-horizontally Thanks!

  • Lightning effect in opengl es

    - by sad_panda
    Is there a way to create a lightning effect on the iPhone using opengl?(like this app) Right now I have modified the glpaint sample to draw random points around a line (between two points that the user touches) and then connecting them, but the result is a zigzag line that constantly jumps around and lags horribly on the actual device.

  • Does iPhone support "greying out" inactive controls?

    - by iter
    I have a control that goes inactive under some conditions in my iPhone app. I can [setUserInteractionEnabled: NO] on it and it doesn't respond to touches. Its appearance does not change however. Other environments I am familiar with "grey out" inactive controls. I wonder what is the idiomatic way to hint to the user that the control is inactive.

  • Is it okay to programmatically create UITouch and UIEvent objects to emulate touch events?

    - by mystify
    I want to simulate some touches on my UI, without using private API. So one simple way to do it is to simply call those -touchesBegan:withEvent:, -touchesMoved:withEvent:, -touchesEnded:WithEvent: and -touchesCancelled:withEvent: methods inside my custom controls. For that, I would have to create UITouch and UIEvent dummy objects with appropriate data inside. Is this fine with them? Or would they reject my app?

  • UIButton to intercept UITableView's didSelectRowAtIndexPath method

    - by Michael
    I've got a UIButton on a table cell that is meant to pop up a UIActionSheet but the problem is the didSelectRowAtIndexPath captures that touch and its action takes precedence. Any clever way to override that action when the user touches the button and still have the default action when the user presses elsewhere in the cell? Too bad there is no MoveToFront property.

  • Xcode SDK version for testing & release?

    I am just putting the finishing touches to an iPhone app that I have written, signed up to the developer program and installed Xcode 3.2.2 (1650) My question is which version of the SDK should I be using to build my application? I was thinking I should be using the latest 3.2 but when I select that I can only access the iPad simulator ... Should I be using 3.1.3 which runs the iPhone simulator. (NB: I originally developed the app in 3.1.2 cheers gary

  • What does the MS Ajax Framework use location.hash for?

    - by DDaviesBrackett
    I've noticed that the MS ajax framework touches the action of the default form during Sys.Application.initialize, appending location.hash to it. This is interfering with other code in my app that expects different behaviour. What does the framework do with that? It refers to the values it puts on the hash as 'state', but how do I find out what it's communicating and from where?

  • Proper way to resignFirstResponder when a UITableView is touched?

    - by Topher Fangio
    Hello all, I have a pretty simple UITableView who's cells contain UITextFields and I need to be able to call resignFirstResponder to hide the keyboard whenever a user touches the UITableView outside of one of the cells. I have read this question/answer but it seems like a very rudimentary way to achieve this. I have read about a way to do it by converting the UITableView to a UIControl so that you can connect the TouchDown event. Does anybody know the standard or preferred way to achieve this functionality?

  • iOS: Gesture recogniser for smooth scrolling and flicking a View

    - by AppleDeveloper
    I am building an iPad app where I needed to allow resizing views functionality using divider view provided between two views. This divider view is just a 20px height view between two half screen content views - please refer attached images. When user scrolls this divider view up or down, both content views changes their sizes appropriately. I have extended UIView and implemented this using touchMoved delegate as code given below in touchesMoved delegate. It works fine. The only thing is missing with TouchMoved is you can't flick divider view to top or bottom directly. You have to scroll all the way to top or bottom! To support flicking the view I have tried UIPanGestureRecognizer but I don't see smooth scrolling with it. When I handle split position change in UIGestureRecognizerStateChanged state, just touching divider view flick it to top or bottom. Handling split position change in UIGestureRecognizerStateEnded does the same but I don't see content view resizing with dividerview scrolling! Could someone please tell me how could I achieve both smooth scrolling of divider view with resizing content views(like touchMoved) and flicking the view. Any alternative approach would also fine. Thanks. - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; if (touch) { CGPoint lastPt = [touch previousLocationInView:self]; CGPoint pt = [touch locationInView:self]; float offset = pt.y - lastPt.y; self.parentViewController.splitPosition = self.parentViewController.splitPosition + offset; } } - (void)handlePan:(UIPanGestureRecognizer*)recognizer { CGPoint translation = [recognizer translationInView:recognizer.view]; CGPoint velocity = [recognizer velocityInView:recognizer.view]; if (recognizer.state == UIGestureRecognizerStateBegan) { } else if (recognizer.state == UIGestureRecognizerStateChanged) { // If I change split position here, I don't see smooth scrolling dividerview...it directly jumps to the top or bottom! self.parentViewController.splitPosition = self.parentViewController.splitPosition + translation.y; } else if (recognizer.state == UIGestureRecognizerStateEnded) { // If I change split position here, the same thing happens at end and I don't see my divider view moving with my scrolling and resizing my views. self.parentViewController.splitPosition = self.parentViewController.splitPosition + translation.y; } } Initial screen Increased top view size by scrolling divider view Top view is totally hidden here but I have to scroll divider view all the way to top. I want to flick the divider view so that it directly goes from any position to top

  • Polishing an user interface

    - by elec
    Looking for examples of some "final touches" to enhance an existing (raw) user interface. I.e nothing related to the core functionalities of the application, but rather examples of all these little details which give an application a "polished" look (new fonts, change in layout, more descriptive labels...others ?) The target platform will be a mobile platform (android/iphone). Note that I'm severly graphically impaired regarding colour and shape combinations, so anything too sophisticated will probably pass me by completely ;)
