I need to know whether Codename One supports zxing. If not, Is there any other way to scan the QR code with Codename One? I need to use this on both android and iPhone. Is it possible with Codename One?
We intend to add support for that relatively soon. If you have specific requirements please open an issue/RFE, we tend to promote RFE's from community members faster.
here is a working example how to use zxing within codenameone via native calls.
there's also a codenameone class for scanning barcodes (javadoc). You could find a usage example here.

I've recently developed an application that view a panorama 360 image, using Panoramagl library for iPhone, and i wanna enhance it and make more features like hotspot.
I've tried to look at a javascript code that implement this feature, but it's useless.
I don't know from where to start implementing this feature and i don't understand the concept of the hotspot. can anyone put me on the right way to start implementing this feature ?
thx in advance.
I've ended up using a library called KRPano using it in UIWebView, it has a good support and has a lot of features.
PanoramaGL for iOS was updated recently to 0.1 r3 version. This new version support Spherical images 2048x1024 pixeles. And hotspots feature was added.

develop android apps that should support iphone,ipad,android.is there any way for developing this kind of generic app or we need to develop aps depending on mobile os
Though it is possible to create an universal application for iphone and ipad i don't think you can do the same for Android.
In my opinion it is always better to port your application to Android based on your requirements so that you can take advantages of the API's that the platform is offering you.
You can try using a framework named Titanium Appcelrator. This framework will help you target iPhone, iPad, Android with the same code base. This also lets you access most of the Native hardware features available with these platforms but not all. It seems that this also may support Blackberry soon.
We are struggling with the same question at the moment. Since we are working for Android, Maemo, Meego, iPhone and Blackberry (+Symbian 3 soon), HTML5 looked promising, and we dedicated quite some time investigating it. The end result was HTML5 is not yet ready for the development we were hoping for. It's fine if you need simple functionality, but as soon as something more advanced is needed, you need to create a different version. Even if it suits your needs, every platform requires different HTML5-to-native bridge, and every platform has a different engine. As you can see, only front end part could be partially used.
In your case, you need two different applications, one for Android, another one for iPhone/iPad. Try to see if you could take advantage of HTML5, if not, you are unfortunately stuck with separate development for some time to come. Unless you will create a web app and use it with device's browser.
You can create common functionality libraries with C or C++ and use these libraries in iPhone/iPad and use Android's NDK tool to integrate theses libraries with Android
On Android, you're using Java as the main language, and you can also use C and C++ . On iOS, you're using Objective-C as the main language, and also can use C and C++. So the common denominator would be C (at least on the iPhone there are no C++ GUI classes). I have no idea about developing on Android, but on iPhone it's no fun to purely work in C (and I'm not sure if it's even possible, maybe it is but should I when working with Objective-C/Cocoa is fun).
What you can do is write generic logic and share that between both systems, like a library. For example, I worked on a project where we used a C++ SIP/VoIP library that also compiles and runs on Symbian. It shouldn't be a big problem to write C code that can be shared between iOS and Android, as long as it is mostly about logic and not about calling system-specific stuff (you can of course include system specific stuff and guard that with #ifdef but you don't want your library to have more system-specific than system-agnostic code, I guess). For example, if you intend to write a networked game you could implement the network protocol in a way that could be shared between iOS and Android.
But as soon as you're hitting the GUI level I don't think you can share any code, and even if you could you probably don't want to because if you use the native languages/IDEs you are faster designing the GUIs each in their respective main languages/IDEs than trying to find a common way and then have to live with compromises and trying to make it work on both systems all day long. Better to implement the GUI native to each platform (e.g. Xcode has a very good graphical tool called Interface Builder that can save a lot of work/typing).
we can go for the XML VM to run the android apps in iphone.

I am trying to use Aptana to build an IPhone web application. I've never use Aptana. I downloaded the iphone support and started a new project. It is now asking me if I want to import a javascript library and lists the "big ones." Will IPhone's Safari be able to use these, specifically jquery? I saw that jquery had a special iphone library so my guess is no.
Should I tell it to use jquery (or other library) or should I download the special iphone javascript subset manually and try an integrate it in my project?
As far as I know JQuery should work fine on the iPhone. The specific libraries you are talking about must be additions to take advantage of iPhone only features like being able to handle the display orientation event or maybe use the webkit css animation extensions.
Although you will need to be careful with events since most mouse related events on the iPhone behave a little different from what you might expect. This presentation by PPK offers some clues about it:

Yep, iphone should run jquery just fine. The javascript support is surprisingly capable. Although you may want to look at some of the iPhone specific libraries out there. I forget their names. iUI I think?
I know it's been asked before (like here), but is there way to natively use XSLT on the iPhone? If not, and I need to use libxslt, is there any documentation/tutorial of how to use it on the iPhone?
EDIT:
I've decided to use libxslt. What files are necessary to include? I haven't found any tutorials of examples of use on the iPhone, and I'm unsure of how to approach it. Any help would be appreciated.
Thanks in advance.
Cannot use libXSLT on iPhone. Not as of today. App will be rejected. libXSLT is built into the iOS andd COULD be called - but this is a private API of the iPhone and will cause rejection. If you compile the libxslt library yourself and statically link it to your app, you will still get rejected. Many people have reported this bug in the app review process but nothing has yet changed.
It depends how you want to use XSLT; not sure what you mean by "natively". If you're just embedding a browser, MobileSafari will interpret XSLT for you.
If you're just converting one XML document into another for processing, libxslt is not a bad choice. There's no difference using libxslt on the iPhone from any other platform. Given Apple doesn't include headers for it, it is likely they don't want you using the bundled copy. You are better off compiling a copy into your application instead, against the provided libxml2 library.
If you want a more specific answer you may wish to pose a more specific question. :-)
I would like to develop a reusable UI control for iPhone. How should I go about doing this? When I say reusable I mean it's packaged in a dll (or whatever is used on iPhone platform) so it can be reused on multiple projects.
While dynamic libraries are not allowed to be used in iPhone applications that are to be sold on the iPhone App Store, here's a tutorial on building static libraries with the iPhone SDK. (assuming you don't want to release source code)
You have two options:
Supply the full source code. Other developers can then add it directly to their app.
Distribute the compiled version of your code as a static library.
As you're planning to develop a UI control, I suggest you also develop an IB plugin and ship that with it too.
You probably want to provide custom Interface Builder objects, or maybe source code libraries.
Well, the Xcode way would be to bundle your code into a Framework and link to that. However, under the iPhone you can't link to non Apple approved frameworks (even if they are your own)
So you would probably have to link in the source to the reusable code. A good article here
