  • BlackBerry 5.0 causing full menu to show on navigationClick

    - by jwadsack
    I have a BlackBerry app that is built for 4.5.x SDK. The first page of the app shows a list of fields and each field can be highlighted and clicked. The click action shows a new view with additional information about the field. This all works fine in 4.5, 4.6 and 4.7 and on the sim with 5.0. On a real 9000 running 5.0, when clicking the trackball on an item in the list, the full menu is showing rather than the click event getting consumed (or even fired) for the field. The view is derived from MainScreen and looks something like this: public class ListView extends MainScreen { public ItemCollection list = new ItemCollection; protected void sublayout( int maxWidth, int maxHeight ) { int i = 1; while(( item == (Item)list.nextElement()) != null) { ItemField field = new ItemField(item, i++); add(field); } } } This class does not consume navigationClick, but shouldn't need to, right? The field class does consume navigationClick event: public class ItemField extends Field { protected boolean navigationClick(int status, int time) { controller.showDeal(item.id, Session.current); return true; } } Is there something that changed in 5.0 that I need to add to have this app work the same for all platforms?

  • Error: undefined method `contact' for nil:NilClass

    - by user275801
    I have a ruby/rails/hobo system that someone wrote a couple years ago, that I need to port to the latest version of ruby/rails/hobo. It seems that ruby doesn't care about backward compatibility, so code that used to work in the old app doesn't work anymore: In the observation.rb model file, the old app has this: belongs_to :survey has_one :site, :through => :survey def create_permitted? acting_user == self.survey.contact or acting_user.administrator? end survey.rb model file has this: belongs_to :contact, :class_name => 'User', :creator => true Unfortunately the code in observation.rb doesn't work under the new ruby/rails/hobo, and it gives me the error: NoMethodError in Observations#index Showing controller: observations; dryml-tag: index-page where line #1 raised: undefined method `contact' for nil:NilClass Extracted source (around line #1): 0 Rails.root: /home/simon/ruby/frogwatch2 Application Trace | Framework Trace | Full Trace app/models/observation.rb:48:in `create_permitted?' How should the "create_permitted" method be changed? I'm finding that the documentation for ruby/rails/hobo is pretty atrocious (which is fair enough as it is free software). Also I don't even know how to begin searching for this on google (i've been trying for days). Please help! :)

  • Exploiting Path Traversal Vulnerability

    - by Maputo
    I have a Java Web App running on Tomcat on which I'm supposed to exploit Path traversal vulnerability. There is a section (in the App) at which I can upload a .zip file, which gets extracted in the server's /tmp directory. The content of the .zip file is not being checked, so basically I could put anything in it. I tried putting a .jsp file in it and it extracts perfectly. My problem is that I don't know how to reach this file as a "normal" user from browser. I tried entering ../../../tmp/somepage.jsp in the address bar, but Tomcat just strips the ../ and gives me http://localhost:8080/tmp/ resource not available. Ideal would be if I could somehow rename the somepage.jsp so that it gets extracted in the web directory of the Web App. But then, the Linux filesystem disallows slashes in filenames (e.g. ../../home/webapp/somepage.jsp). Are there maybe any escape sequences that would translate to / after extracting? Any ideas would be highly appreciated. Note: This is a school project in a Security course where I'm supposed to locate vulnerabilities and correct them. Not trying to harm anyone...

  • Facebook-ios-sdk with embedded UIWebView

    - by Benchtop Creative
    I'm working with the new facebook-ios-sdk and have successfully integrated the api into my native app. I am able to authenticate a user and properly setup permissions using a popup dialog with the ios-sdk classes. For a portion of my app I need to use the facebook connection within a UIWebView, using javascript and html to process data within the webview. Given that the user is already logged in and authenticated via the above routine, I would have assumed that the UIWebView would share those credentials, or that there would at least be some way to pass or assign the credentials to the webview. Unfortunately, I found this earlier post which seems to suggest that this scheme doesn't quite work (iOS - being logged-in in a webView after logging in with the SDK). Has anyone else encountered this and/or found a work around? This seems like it would be a fairly straightforward use case given that I'm not trying to launch mobile safari or something like that - it's all within the same native app. It just seems like there must be some sort of easy trick or setting that I'm missing. Maybe somehow setting cookies in the new UIWebView? or something like this?

  • Google Drive API invalid_grant after removing access

    - by Sparafusile
    I have been writing a desktop application that uses the Google Drive API v2. I have the following code: var credential = GoogleWebAuthorizationBroker.AuthorizeAsync ( new ClientSecrets { ClientId = ClientID, ClientSecret = ClientSecret }, new[] { DriveService.Scope.Drive }, "user", CancellationToken.None ) .Result; this.Service = new DriveService( new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "My Test App", } ); var request = this.Service.Files.List(); request.Q = "title = 'foo' and trashed = false"; var result = request.Execute(); The first time I ran this code it opened a browser and asked me to grant permissions to the App, which I did. Everything worked successfully until I realized I was using the wrong Google account. At that point I logged into the wrong Google account and revoked access to my App. Now, whenever I run the same code it throws an exception: Error:"invalid_grant", Description:"", Uri:"" When I examine the service and request objects, it looks like the oauth_token isn't getting created any more. I know what I did to mess things up, but I can't figure out how to correct it so I can use a different Google account for testing. What do I need to do?

  • how to run TimerTask off main UI thread?

    - by huskyd97
    I am having trouble with a TimerTask Interfering with In App Purchasing (Async Tasks). I am weak with Threads, so I believe it is running on the main UI thread, eating up resources. How can I run this outside the UI thread? I have searched, and tried some suggestions using handlers. but seems like I get the same result, app gets really laggy. when I don't run this task (refreshes every 500mS), the activity runs smoothly, and there are no hangs during In app purchases. Your help is appreciated, code snippet below: public class DummyButtonClickerActivity extends Activity { protected Timer timeTicker = new Timer("Ticker"); private Handler timerHandler = new Handler(); protected int timeTickDown = 20; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mainhd); // start money earned timer handler TimerTask tick = new TimerTask() { public void run() { myTickTask(); } }; timeTicker.scheduleAtFixedRate(tick, 0, 500); // 500 ms each } // End OnCreate protected void myTickTask() { if (timeTickDown == 0) { /// run my code here //total = total + _Rate; timerHandler.post(doUpdateTimeout); } else if(timeTickDown < 0) { // do nothing } timeTickDown--; } private Runnable doUpdateTimeout = new Runnable() { public void run() { updateTimeout(); } }; private void updateTimeout() { // reset tick timeTickDown = 2; // 2* 500ms == once a second } }

  • Subdomain Routing Rules (using chaining) Broke after upgrading to Zend Framework 1.9.5, but only for

    - by Dan
    I asked a similar question months ago (see How do I write Routing Chains for a Subdomain in Zend Framework in a routing INI file?), on how to write chaining rules in an app.ini format. The answer to this question worked wonderfully! Now, however, I have upgraded to the latest version of the Zend Framework 1.9.5 (I needed to upgrade for another issue) and now my subdomains no longer work! To clarify, if I visit subdomain.domain.com, it does not recognize my rule. However, if I visit subdomain.domain.com/somepage/ it does recognize my routing rule. Here is my code: ;; the following is apparently being ignored, and does not work routes.manager.type = "Zend_Controller_Router_Route_Hostname" routes.manager.route = "manager.sitename.com" routes.manager.defaults.module = "manager" ;; this is not being ignored and works! routes.manager.chains.settings.type = "Zend_Controller_Router_Route_Static" routes.manager.chains.settings.route = "/settings" routes.manager.chains.settings.defaults.controller = "manager" routes.manager.chains.settings.defaults.action = "settings" So for example, if I go to manager.sitename.com, it just redirects to my default index and controller (does not access the module, $this-getRequest()-getModuleName() is blank). However, if I go to manager.sitename.com/settings, the page comes up! This app.ini configuration works fine in ZF 1.7.8, But now since I upgraded to 1.9.5, it no longer works. I have tried adding routes.manager.defaults.controller = "manager" and routes.manager.defaults.action = 'index" to my configuration as well, but this didn't work. There is not much out there on the internet with chaining and app.ini dealing with Zend Framework. Any help on this issue would be greatly appreciated.

  • Can't authenticate mobile client with node.js (using passport.js)

    - by Pazinio
    I'm trying to build some CRUD application with node.js as a back-end API (express) and web-app (backbone) and mobile client (native android) as front-ends.(I'm node.js beginner) My server solution is based on the following great tutorial 'easy-node-authentication'. In my android app I have managed to get the user Google-Token after I completed the authentication step with Google Plus SDK.(mobile to google-plus directly request). I'm trying to understand and find right and elegant way to re-use a given google-token and authenticate again my android user through Google-Plus account to ensure the mobile client holds real token, then add a new entry (id, token, email, name) to my users table DB within my node back-end. The question is: what should be my next step in case I want to keep my back-end without changes? should I send a GET request with the token as a cookie to /auth/google? maybe to /auth/google/callback? another URL? Does this make sense at all? Please note: I'm aware to the fact the mentioned above 'easy-node-auth' solution is based on sessions and cookies. having said that, i'm still trying to understand if there is a convenient way to integrate both (android and node) as it works good for my web-app and node. Thanks in advance.

  • passing info from facebook to UITabBarController

    - by EquinoX
    When my app first start, it shows up a main page showing to login to facebook and then it goes to the UITabBarController. The code that I have in my app delegate is the following: //this is the .h @interface NMeAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MainViewController *controller; UITabBarController *tabBar; } @property (nonatomic, retain) IBOutlet UITabBarController *tabBar; @property (nonatomic, retain) MainViewController *controller; @property (nonatomic, retain) IBOutlet UIWindow *window; @end //this is the .m of the app delegate #import "NMeAppDelegate.h" @implementation NMeAppDelegate @synthesize window; @synthesize tabBar; @synthesize controller; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. controller = [[MainViewController alloc] init]; [window addSubview:tabBar.view]; [window addSubview:controller.view]; [window makeKeyAndVisible]; return YES; } Inside of MainViewController, I actually have a Facebook * facebook object, which basically has all of the information that I need. Every information that I need for this apps is queried in the MainViewController. The problem is that after getting this info and now I am in the UITabViewController... how do I get those information that I already queried facebook for? I have a class called UserInfo as well, which basically has everything essential I need. I need to have the info from UserInfo so that the other ViewController in the UITabBarController have access to it.... I hope my question makes sense

  • The right approach to loading dynamic content into a UITableView in iOS

    - by OS.
    ok, I've read tons of bits and pieces on the subject of loading dynamic content (from the web) into a UITableView and the problem with calculating cell height upfront. I've tried different simple implementations but the problem persists... Assuming I need to read a JSON file from the web, parse it into 'item' objects, each with variable size image and various text labels, here is what I believe would be the right approach to avoid long hang time of the app while everything is loading: on app load read JSON file and parse into items array provide only small part of the items array to the tableview (about 10 items) - since I need to load the images associated with each item to calculate cell height - I don't want the view to go through the whole items list and load all images - this hangs the app until every image is loaded display the tableview with the available cells (assuming I load a few 'spare' ones, user can even scroll to more items) in the background using Grand Central Dispatch download images for all/some of the remaining items and then reload the tableview with the new data (repeat step 4 if item list is very long) Step 2 above is necessary since I have no way to calculate the cell height without loading the images first, and since tableview first calculates height of all cells it may take a very long time to download all images for all items. Would you say this is the right approach? am I missing something?

  • Weird Rails database errors

    - by Jason Swett
    I've had some trouble getting my Rails app to connect to PostgreSQL so I decided to just say screw it and use SQLite for now. (I'm using the tutorial here: http://guides.rubyonrails.org/getting_started.html) I started a BRAND NEW, fresh Rails app from this tutorial. When I visit my app in the browser after deleting public/index.html, I get this the first time: Please install the pg adapter: `gem install activerecord-pg-adapter` (no such file to load -- active_record/connection_adapters/pg_adapter) That's odd to me because I'm not mentioning PostgreSQL anywhere. Here's my databases.yml: # SQLite version 3.x # gem install sqlite3-ruby (not necessary on OS X Leopard) development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: sqlite3 database: db/test.sqlite3 pool: 5 timeout: 5000 production: adapter: sqlite3 database: db/production.sqlite3 pool: 5 timeout: 5000 To make things more confusing, I only get that "pg adapter" error on the first load. For every subsequent page request, I get this error: ActiveRecord::ConnectionNotEstablished So even though I removed all mention of PostgreSQL, I'm still getting errors. What could be going on?

  • iPhone settings not honoured

    - by winsmith
    My iPhone app has the following problem: Freshly installed, when I read out my "Play Sound" preference with the following code: defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"Play Sounds? %d", [defaults boolForKey:@"play_sounds_preference"]); The setting always reads out as false, even though the default setting is set to true. Any ideas? Here is my Root.plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>StringsTable</key> <string>Root</string> <key>PreferenceSpecifiers</key> <array> <dict> <key>Type</key> <string>PSGroupSpecifier</string> <key>Title</key> <string>General Settings</string> </dict> <dict> <key>Type</key> <string>PSToggleSwitchSpecifier</string> <key>Title</key> <string>Sounds</string> <key>Key</key> <string>play_sounds_preference</string> <key>DefaultValue</key> <true/> </dict> </array> </dict> </plist> When the user opens the Settings.app and navigates to my app's name, THEN the setting reads out as true, even if the user doesn't change anything.

  • Launching and Intent from file and mime type

    - by stonedonkey
    I've reviewed all the similar questions here, but I can't for the life of me figure out what I'm doing wrong. I've written an application that tries to launch various files, sort of a file browser, when a file is clicked it tries to launch the program based on it's associated MIME type or I want it to present the "Choose Application to Launch" dialog. Here's the code I'm using to launch: File file = new File(app.mediaPath() + "/" +_mediaFiles.get(position)); Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW); String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString()); String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension); myIntent.setDataAndType(Uri.fromFile(file),mimetype); startActivity(myIntent); This fails and generates a: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///file:/mnt/sdcard/roms/nes/Baseball_simulator.nes } Now if I install OI File Manager for instance, it opens instead of this error being thrown, and then if I click the same file from within in it, it launches the approriate dialogs. I have noticed that the MIME type for that particular file fails, but other mime types like .zip do return values. Am I missing something that when the MIME type is null to call a dialog that lets the user select? I've tried other variations of launching the app, including not setting the mime type and only using .setData with no success. The action I want to happen is, a user clicks a file, if it's associated with an application that app launches, if not, the user gets the "Complete action using" dialog with a list of apps. Thanks for any advice.

  • Best way to import a pack or "system" of new classes??

    - by Joe Blow
    Here's an Advanced question for Advanced developers. So I've written a largish "subsystem". It is essentially a UIViewController called CleverViewController which is a UIViewController. Now, there are a large number of supporting classes (about ten) that do the hard work: perform math functions, image processing, purely logical functions, build images or what have you with thousands of lines of code. (To do this, I simply started a new XCode project / app "Scratchpad" which does little other than load and launch the CleverViewController. So currently it works as an app, which launches CleverViewController. The ten or so classes I mention that are part of the "subsystem" simply sit there in that project/app.) So now, we will use CleverViewController, the new technology generally, in various apps. (Or perhaps friends would want to use it, etc.) What's the best way to "do" this? Have I screwed everything up, and really it should just be ONE (pretty big) class rather than a dozen classes? (I could understand that then as I would simply add that new (big) class where needed, like adding any other class.) Do I have to make a "framework" like the Apple frameworks? (If so, what the hell are they, how do you do it, etc?!?) In fact, do you just have to lamely include all of the dozen classes and that's that (obviously perhaps putting them in a grouped subfolder). What about all the headers and so on? (Currently I just have the dozen includes in the pch file of the scratchpad project.) Shouldn't it be easy to "maintain" this "subsystem" separately and so on? I'm afraid I know nothing about this: if the answer is obvious, hit me over the head and let me know. Thank you for any info on this !

  • Coloring Default Buttons - color filter only on unfocused state

    - by rlo
    I want to buttons of different colors, but I want to do so while using the default button background resource in order to preserve the onfocus and onclick states. This is because I want to use the default highlight color of the OS for my app, which is NOT always orange (HTC Sense makes it green). I found that adding a color filter to the button's background drawable works great (in this case, blue): myButton.getBackground().setColorFilter(Color.parseColor(this.getString (R.color.button_blue)), Mode.MULTIPLY); BUT, when the button is focused or clicked, it turns a nasty orange_blue because it mixes the color filter with the orange of the background drawable. I want to ONLY set this color filter for the unfocused/unclicked nine- patch drawable within the default button's statelistdrawable. I'm not sure how else to do this. I see a similar solution here: http://stackoverflow.com/questions/2065430/fixed-android-detecting-fo... but I have some concerns with that solution, mainly what if the OS changes the graphic of the default button? Since the normal unfocused/ unpressed graphic is now hardcoded into the app, it would break the flow. Maybe can someone comment on whether it would be good or bad practice to hardcode the default graphic into the app? What are the chances of the OS completely changing the graphic? Any help please? Thanks very much!!

  • How to reference {{outlet}} in Ember.CollectionView's itemView

    - by ceed
    I am new to ember and ran into a problem and could not find an answer online. I have a collectionView App.MyView = Ember.CollectionView.extend({ itemViewClass: 'App.MyViewItem', contentBinding: 'controller' }); and the itemViewClass App.MyViewItem = Ember.View.extend({ templateName: 'mytemplate' }); the template looks like that: <div {{action 'select' view.content}}>{{view.content.name}}</div> {{outlet detail}} </div> This produces the content list just fine. In the controller, I have an action: select: function(evt){ this.transitionToRoute('item', evt); } What I want to do is to transition to a nested route when selecting the item (which works fine) and also load more data of the selected item into {{outlet detail}}. While I can load the content of the "item" route into an outlet of e.g. application.hbs, I don't know how to reference the outlet of the selected collectionView item so that the detailed contents are displayed within the existing view. I tried to use: this.render('item', { outlet: 'detail', into: '????' }); within the item Route, but I don't know how to reference the collectionview item template. Maybe there's also a much easier way of loading more data from an item in the item's view (while changing the route at the same time). Any help would be appreciated.

  • Fake location for the device (custom)

    - by AtomRiot
    I know there are a few apps out there to fake a devices location but specifically what i want to do is use a location grabbed from a url. What direction should I look for setting the location on the device. The scenario i have is a jailbroken Wi-Fi iPad tethered to a nexus one. The nexus one would host a background service that when a request is recieved, it would respond with gps data of its current location. The jailbroken ipad would have a background service that either updated the location on a time interval, or on a per request basis (depending on how i have to implement it) by submitting a request to the tethered nexus one service. That data would then be set on the ipad and an application requesting location would get the service data. The goal is to recreate the location faker app's functionality with the exception of the spoofed location comes from the nexus ones gps via the service but i have not yet found out how to set the location data for the device. I can ofcourse implement this in a per app basis but it would be awesome to have any app be able to use it.

  • EXE stops working if containing folder is renamed. MSVCP90.dll

    - by John
    This popup comes up as soon as the app is started: The program can't start because MSVCP90.dll is missing from your computer. Before anyone says "install the VC++ runtimes", wait! If I rename the folder containing my .EXE then the app runs. If I rename it back, it breaks. The app has been running for weeks without any changes to my system/VS installation (2008 SP1), we suddenly spotted this error a few days ago. Lost as to why the name of the dir is causing issues... again this has not changed in months and all our resource paths are relative anyway, e.g "../someOtherDir/...." It doesn't just do this on my PC, we have the /bin dir (the one containing EXE) in SVN and suddenly everyone started seeing the same issue, even though the binaries themselves seem just fine. Is it possible some additional data got put into SVN and that's the cause? Since it's not just one PC, there must be something either in SVN or the EXE itself... Note this popup comes before our code even gets to run.

  • URL path changes between dev and published version

    - by Bob Horn
    I just got Scott Hanselman's chat app with SignalR working with ASP.NET MVC 4. After hours of configuration, trial and error, and getting different versions of Windows to talk to each other on my home network, it's all working except that I'm left with one issue that I'm not sure how to handle. This line of javascript has to change, depending on if I'm running the app through Visual Studio or the published (IIS) version: Works when running within VS: var connection = $.connection('echo'); Works with published version: var connection = $.connection('ChatWithSignalR/echo'); When I run within VS, the URL is: http://localhost:9145/ And the published version is: http://localhost/ChatWithSignalR If I don't change that line of code, and try to run the app within VS, using the javascript that has ChatWithSignalR in it, I get an error like this: Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:9145/ChatWithSignalR/echo/negotiate?_=1347809290826 What can I do so that I can use the same javascript code and have it work in both scenarios? var connection = $.connection('??????'); Note, this is in my Global.asax.cs: RouteTable.Routes.MapConnection<MyConnection>("echo", "echo/{*operation}");

  • Using AJAX in Rails: How do I change a button as soon as it's clicked?

    - by sdc
    Hey! I'm teaching myself Ruby, and have been stuck on this for a couple days: I'm currently using MooTools-1.3-compat and Rails 3. I'd like to replace one button (called "Follow") with another (called "Unfollow") as soon as someone clicks on it. I'm using :remote = true and have a file ending in .js.erb that's being called...I just need help figuring out what goes in this .js file The "Follow" button is in a div with id="follow_form", but there are many buttons on the page, and they all have an id = "follow_form"...i.e. $("follow_form").set(...) replaces the first element and that's not correct. I need help replacing the button that made the call. I looked at this tutorial, but the line below doesn't work for me. Could it be because I'm using MooTools instead of Prototype? $("follow_form").update("<%= escape_javascript(render('users/unfollow')) %") ps. This is what I have so far, and this works: in app/views/shared: <%= form_for current_user.subscriptions.build(:event => @event), :remote => true do |f| %> <div><%= f.hidden_field :event %></div> <div class="actions"><%= f.submit "Follow" %></div> <% end %> in app/views/events/create.js.erb alert("follow!"); //Temporary...this is what I'm trying to replace *in app/controllers/subscriptions_controller.rb* def create @subscription = current_user.subscriptions.build(params[:subscription]) @subscription.save respond_to do |format| format.html { redirect_to(..) } format.js {render :layout} end Any help would be greatly, greatly appreciated!

  • Mobile site not rendering mobile within iframe

    - by user2788371
    I'm launching a mobile version of an existing corporate web application that currently loads in an iframe for corporate authentication purposes. When accessing the web app's direct link from a mobile device, it displays beautifully. The problem is that when accessing through the iframe, the site doesn't seem to scale correctly and it looks more like I'm accessing the desktop version of the site. Any suggestions on how make the site within the iframe recognize the mobile device's width and adjust appropriately? I've tried setting the viewport within the HTML and CSS of the site being loaded and even then I'm not getting the change I expect on my iPhone. I haven't had the opportunity to test an Android yet but within our company, iOS is the most important. Some of snippets of code I have tried are listed below. I've also tried 480px and device-width (which I believe I can't access because the iframe is a different domain). Unfortunately, modifying the iframe page and settings are not an option. Also, Javascript cannot be used as a solution for other reasons. Within HTML of web app site: <meta name="viewport" content="width=320px, initial-scale=1.0, user-scalable=no" /> Within CSS of web app site: @viewport { width: 320px; } The above CSS does not seem to render even when not used in device specific @media code.

  • iPhone SDK File Handler with iOS 4 Background Processes

    - by David Higgins
    The "application:applicationDidFinishLaunchingWithOptions:" message does not get called when an application is sitting in the background in iOS 4, and I'm trying to figure out how to be notified when the application is brought back into the foreground by another application. My application registers itself as a handler for certain file types, and Safari and other supported applications allow passing the files over to my app. This works great if the app is closed before I try to use it, but fails otherwise. In my application:applicationDidFinishLaunchingWithOptions: I have: NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey]; if([url isFileURL]) { } [self.window makeKeyAndVisible]; return YES; As stated already, this works great so far for starting the app when it's not sitting in the background - but when I switch back over to Safari or Mail and try to open a new file that is supported, my application wakes up from the background and becomes active again but I can't see any "withOptions" overrides for application:applicationWillEnterForeground: or any way to identify what was passed in when it enters the foreground. What would be the appropriate way to receive these "open file notifications" when the application is in the background?

  • How to stop calling the Activity again when device orientation is changed??

    - by user1460323
    My app uses Barcode Scanner. I want to launch the scanner when I open the app so I have it in the onCreate method. The problem is that if I have it like that, when I turn the device it calls again onCreate and calls another scanner. Also I have the first activity that calls the scanner. it has a menu so if he user presses back, it goes to that menu. If I turn the screen on that menu, it goes to barcode scanner again. To solve it I have a flag that indicates if it is the first time I call the scanner, if it's not I don't call it again. Now the problem is that if I go out of the app and go in again it doesn't go to the scanner, it goes to the menu, becasuse is not the first time I call it. Any ideas?? Is there a way to change the flag when I go out of my main activity or any other solution?? My code. private static boolean first = true; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); integrator = new IntentIntegrator(this); if (first) { first = false; integrator.initiateScan(); } }

  • How to use XML namespace prefixes without xmlns="..." everywhere? (.NET)

    - by LonelyPixel
    The subject is probably too short to explain it... I'm writing out XML files with no namespace stuff at all, for some application. That part I cannot change. But now I'm going to extend those files with my own application-defined element names, and I'd like to put them in a different namespace. For this, the result should look like this: <doc xmlns:x="urn:my-app-uri"> <a>existing element name</a> <x:addon>my additional element name</x:addon> </doc> I've used an XmlNamespaceManager and added my URI with the prefix "x" to it. I've also passed it to each CreateElement for my additional element names. But the nearest I can get is this: <doc> <a>existing element name</a> <addon xmlns="urn:my-app-uri">my additional element name</addon> </doc> Or maybe also <x:addon xmlns:x="urn:my-app-uri">my additional element name</x:addon> So the point is that my URI is written to every single of my additional elements, and no common prefix is written to the document element where I'd like to have it. How can I get the above XML result with .NET?

  • Application crash

    - by Ovi
    I have an application that, as any other app, crashes once in a while for various reasons. When it crashes, it does it gracefully and the users get a nice message of the crash. At the same time the crash is reported on the server for analysis so it can be fixed in future versions. However, I would like that the app keeps working through the crash. What that means is that I would like to run the forms in an 'atomic' way. If it goes down, it doesn't take down the entire app. The users should just need to start over the work done with the particular form. Is this something that can be done through architecture? Or maybe the new framework versions has something to aid this? The application is build mostly in C# over the 3.5 framework, but it also uses some external references, some COMs and web service references. I am not interested in an answer: 'well fix the crashes'. Me and my team and the testing team are working round the clock for this.
