• CCUserDefault, iOS/Android and game updates

  - by Luke

  My game uses cocos2d-x and will be published on iOS platform first, later on Android. I save a lot of things with CCUserDefault (scores, which level was completed, number of coins taken, etc...). But now I have a big doubt. What will happen when the game will receive its first update? CCUserDefault uses an XML file stored somewhere in the app storage space. This file is created and retained until one uninstalls the app. I am wondering what happens when the app is updated. Will the old XML file be maintained? Because if not, how should I handle app updates (updates in the sense that 2, 3 or more new level packages will be added, but the informations about the old ones, like scores, which level was finished and which not, number of coins, etc., need absolutely not to be lost)?

• Développement d'applications professionnelles avec Android 2 de Reto Meier, critique par Benwit

  Je viens de lire "Développement d'applications professionnelles avec Android 2" de Reto Meier, ingénieur chez Google. [IMG]http://images-eu.amazon.com/images/P/274402452X.08.LZZZZZZZ.jpg[/IMG] Je le trouve très complémentaire aux tutoriaux qu'on trouve sur Internet. Il aborde beaucoup de sujets et le nombre de pages n'est pas dù à des captures d'écrans ! Ce que j'ai particulièremen apprécié, ce sont toutes les petites informations tirées de son expérience qu'il distille au fil des pages. L'avez vous lu ? Si oui, par rapport à d'autres livres sur le sujet ? Allez vous le lire ?...

• Android performance/issues with Corona SDK?

  - by B5Fan74

  I know this is a fairly broad question. We are looking to develop a mobile game and want to use a multi-platform engine/SDK. We like what we see with Corona but in doing some reading, we are seeing a lot of references to poor performance on the 'droid platforms. I am unsure how much of this is still relevant? Many of the articles/posts/references/discussions vary in date from 18 months ago to earlier this year. Is there a reason we should not pursue Corona if Android support is important to us? The game is going to be 2D isometric view. Thanks!

  Mise à jour du 13/05/10 Apple ? Android : HTC contre-attaque En demandant comme Nokia l'interdiction totale d'importation et de vente des iPhone, iPad et iPod HTC met ses pas dans ceux de Nokia. Dans l'affaire qui l'oppose à Apple (lire ci-avant), la société a décidé de contre-attaquer en utilisant la méthode forte, tout comme le constructeur finlandais. HTC, principal utilisateur du système d'exploitation mobile de Google, répond à Apple en l'accusant à son tour de violation de brevets. L'affaire sera portée devant la décidément très occupée ITC (U.S. International Trade Commission). Mais HTC ne s'arrête...

  - by ProfessionalAmateur

  I'm running Ubuntu 11.10 (64-bit) as a VirtualBox guest on a Win7 64-bit host. When I plug in my Android Epic4g (Galaxy S) both the host and guest see the device properly, however lsusb does not. When I run dmesg I get the following: [ 361.664219] usb 1-2: new full speed USB device number 79 using ohci_hcd [ 362.428798] hub 1-0:1.0: unable to enumerate USB device on port 2 [ 363.313782] hub 1-0:1.0: unable to enumerate USB device on port 2 I get the same type of dmesg message with the USB 2.0 (ECHI) Controller enabled and disabled for the guest OS.

• Best platform for android and ios game?

  - by LoveMeSomeCode

  Ok, this has been asked before, but not recently, and most of the answers were just 'buy a mac'. So we're a couple guys who've been making small flash games, and now we want to go mobile, and there seem to be lots of options. Does anyone here have experience with one or more of these platforms to tell us the pros and cons of each? Corona AIR 3 Rhodes Could someone with experience compare and contrast these to each other and native development? We want to cast the widest net with the least re-work so we'd like to target just Android and iPhone, and we'd like it to be an actual app in the market instead of just a mobile website. We have experience in Actionscript, Javascript, and C#.

• Google multiplie les APIs pour les développeurs : du GPS pour Android à la Business Intelligence pou

  Google multiplie les APIs pour les développeurs Du GPS pour Android à la Business Intelligence pour tous Oui, Google a frappé un grand coup lors de son traditionnel Google I/O. Cela ne veut pas dire que Google est le « meilleur » ou que la concurrence n'existe pas, mais une chose est sûre, le nombre des annonces majeurs lors de l'évènement à marqué les esprits (cf. la rubrique "Lire aussi", ci-dessous). Un point que nous n'avons pas encore abordé est celui de la multiplication des APIs que Google a mis à la disposition des développeurs webs et/ou mobiles. Deux ont particulièrement retenu l'attention des observateurs. La première ?

• Options for 2D Web/iPhone/Android, with Test Framework

  - by ashes999

  I would like to make a 2D game with one codebase that runs on iPhone, Android, and web (any flavour of web -- HTML5, Flash, Silverlight, etc.) What are my options? I should be able to write my code once, and run it anywhere. I also absolutely need the ability to write unit tests (or write a unit-testing framework) -- I cannot make sizable games without testing. Unity is good, but unity is 3d; even with hacks, the graphical assets will still be 3d. I'm after 2d, not 3d. (If you need a Mac or separate licensing for the Mac part, that's okay.)

• Android custom widget styles: how to put them into a namespace?

  - by Matthias

  In the ApiDemos, there is a view example called Gallery1 which declares a custom style in attrs.xml, as such: <declare-styleable name="Gallery1"> <attr name="android:galleryItemBackground" /> </declare-styleable> now, I want to do the same thing for my widgets, but using a different namespace. However, as soon as I replace the android: namespace with something else, I get this error: ERROR: In Gallery1, unable to find attribute myns:galleryItemBackground Unable to find attribute? Why does it look for an attribute I am about to declare? Isn't the point of this file to be able to name your own custom attributes? It's interesting to note that it works if you do not supply a custom namespace, but just an attribute name.

• Flat File Connection Manager in SSIS package shows "Valid File Name Must be Selected"

  - by Traples

  (Flat File Location) Samba Share | Windows Share (SSIS) _______________________________ | | XP 32bit | Works | Works | | 2003 Serv 32bit | Works | Works | | Vista 64bit | ERROR | Works | | Win 7 64bit | ERROR | Works | | 2008 Serv 64bit | ERROR | Works I created an SSIS package in VS 2008 that parses a flat file from a shared folder and puts the records into a SQL Server db. I recently installed Windows 7 and VS 2008 on a new workstation. When I import the package from TFS and open it, I get the error Validation error. Parse and Import Catalog Flat File: MySSISPackage: The file name "\\shared\flatfile.txt" specified in the connection was not valid. When I open the Flat File Connection Manager Editor, there is an error stating: A valid file name must be selected I can browse to and select the file from inside the editor, but I cannot change any properties, or move away from the General tab because of this error. If I go back to my laptop (Windows XP), where the package was first created, there is no error. Both workstations are on the same domain, and I'm logging in using the same credentials. Any ideas as to why I would receive this error from one workstation and not another? UPDATE: If I take the .dtsx package from the running workstation and load it into SSIS on the server, I get the following errors when it tries to run: Error: The file name "\\shared\flatfile.txt" specified in the connection was not valid. and... Error: Connection "MySSISPackage" failed validation. and... Error: The file name property is not valid. The file name is a device or contains invalid characters. UPDATE 2: a) The Shared folder I'm trying to pull the flat file from is a Samba share on a Unix box. b) If I access the file using SSIS on any 64-bit platform (Windows 7 64-bit, Vista 64-bit, Windows Server 2008) I get the error "A valid file name must be selected." c) Accessing the file using SSIS from 32-bit environments (Windows XP 32-bit, Windows Server 2003 32-bit) there is no problem. d) If I move the file to a shared folder on a Windows server, 64-bit SSIS recognizes the file.

Event Type: Error Event Source: SQLISPackage100 Event Category: None ... Description: Package "Foo" failed. I hope the answer is simple, but does anyone know how to change the text of the Event Log Source?

• How do I call window.openDatabase from a webView hosted in an android application?

  - by Kevin

  I created a native Android app that basically hosts a webView control. That webView is then used to load a page that calls window.openDatabase from JavaScript. I can successfully confirm that the API exists by verifying window.openDatabase. Calling this method returns a null when called in a hosted webView control. Calling the same method in the Android Browser returns an instance of the database. Does anyone know the permessions in the manifest or settings on the webView control that need to be set to access the database? Is this even possible in a native app.

Other packages it can find just fine. The image below shows the problem. I have highlighted the gdata-media package in eclipse, as its the first package on the console that its not able to find: Click for full size What am I doing wrong?

• Does oneway declaration in Android .aidl guarantee that method will be called in a separate thread?

  - by Dan Menes

  I am designing a framework for a client/server application for Android phones. I am fairly new to both Java and Android (but not new to programming in general, or threaded programming in particular). Sometimes my server and client will be in the same process, and sometimes they will be in different processes, depending on the exact use case. The client and server interfaces look something like the following: IServer.aidl: package com.my.application; interface IServer { /** * Register client callback object */ void registerCallback( in IClient callbackObject ); /** * Do something and report back */ void doSomething( in String what ); . . . } IClient.aidl: package com.my.application; oneway interface IClient { /** * Receive an answer */ void reportBack( in String answer ); . . . } Now here is where it gets interesting. I can foresee use cases where the client calls IServer.doSomething(), which in turn calls IClient.reportBack(), and on the basis of what is reported back, IClient.reportBack() needs to issue another call to IClient.doSomething(). The issue here is that IServer.doSomething() will not, in general, be reentrant. That's OK, as long as IClient.reportBack() is always invoked in a new thread. In that case, I can make sure that the implementation of IServer.doSomething() is always synchronized appropriately so that the call from the new thread blocks until the first call returns. If everything works the way I think it does, then by declaring the IClient interface as oneway, I guarantee this to be the case. At least, I can't think of any way that the call from IServer.doSomething() to IClient.reportBack() can return immediately (what oneway is supposed to ensure), yet IClient.reportBack still be able to reinvoke IServer.doSomething recursively in the same thread. Either a new thread in IServer must be started, or else the old IServer thread can be re-used for the inner call to IServer.doSomething(), but only after the outer call to IServer.doSomething() has returned. So my question is, does everything work the way I think it does? The Android documentation hardly mentions oneway interfaces.

• Android SDK and AVD manager will not run from Eclipse after upgrade to SDK 5 and ADT 0.9.6

  - by user303944

  Using Windows 7, 64 bit system. Prior to upgrade I was able to run "Android SDK and AVD manager" from Eclipse via a tool bar icon and menu option, both of which still exist. However now nothing happens when I try to run the manager. As a result I can't start an emulator from within Eclipse. When I use Eclipse to run an Android app, the first emulator I installed is automatically started. Using Windows Explorer, I can still run the manager from the SDK directory in which the update was applied (the update didn't change the location of the SDK). If I run the manager and start multiple emulators and then Run an app from Eclipse, it sees the emulators and allows me to choose one as before. This is a satisfactory work-around, but it would be nice if the manager were fully integrated into Eclipse as it was before.
