CodeName One and OpenCV for iPhone apps - android

I am looking at: CodeName One for iphone app development.
It seems like same code can be used for iPhone, android and other phones. I was wondering if it is possible to use OpenCV along with this API to build the code for different platforms (mainly iPhone and Android). If it is possible then how to do it?
Plus, if anyone has any better suggestion regarding the API (preferrably in java) to develop iPhone apps, please help.

I have used CodeName One for targeting my Android applications to other platforms like iOS, Windows phone etc. It has given good results till now!
Regarding OpenCV, I suggest you write a simple HelloWorld for OpenCV in Android and try targeting it on the iPhone as well. I am not pretty sure about the result but it's worth a try.
CodeName One has a easy setup guide for Eclipse as well as Netbeans so you can just install and give it a try!
If in any case you are stuck, you can always post a question on the forums.

Panorama 360 viewer with phonegap

I read a lot of answers but i dont know wich is correct. Almost mobile browsers doesn support WEBGL, only newest. Almost script, libraries or plugins works with FLASH or WEBGL. I see and read a lot of your documentations and i dont know what to do. I need compatibility with almost smartphones in android and ios. I wanna use PHONEGAP platform to buil the app.
Can you guide me? Thanks a lot
Use CocoonJS instead of Cordova.

Hybrid apps for iOS/Android/Windows 8

I hope this question is specific enough. I have a client for whom I made an iOS native app and an Android native app (same app, different platform). It's a fixed pixel design (I made this work for Android somehow:) and it works on iPad, iPhone and most Android devices (with some letterboxing). Now I am asked to write the same app for the Windows store and they want me to use HTML and JavaScript. My question is, when I use HTML and JavaScript, would it be "easy" for me to use this code into some sort of hybrid solution (PhoneGap, etc)? The app doesn't need much complicated functionality but does need to support push notifications on iOS and it needs to be able to play videos, preferably HLS. Any advice on what the best hybrid solution and do hybrid solutions allow you to build for Windows 8?
I'm a cross-platform developer working on PhoneGap and Titanium Appcelerator. The correct answer is "It depends". Currently the state of cross-platform development is not very recommendable. Yes, you can write plugins for PhoneGap and it does support windows phone but you will have a ridiculously hard time getting them to communicate with each other properly. I learnt this from experience.
If it was a hacking/hobby project to further the cause then I would say go for it but for a time-bound client project like yours, I would recommend against cross-platform solutions and go native instead. Plus native always gives considerably better control, speed and ease of development. You will probably develop it faster in native than cross platform anyway. I've played around with windows SDK and it seems easy to use and well-built with good documentation and you can use C# which is similar to Java since you have already used it on android.
You can also build windows 8 desktop apps using html and javascript natively but this isn't present in windows phone 8 yet.
As I mentioned, If you don't need too many native controls, then you can go cross-platform. For your requirements, it can be done. If you have already developed android and ios apps and only need windows app now, then going native would be easier. But if you have to make all 3 then you can go cross platform if your requirements are restricted to what you mention. Here's a good quora thread that discusses the pro's and cons:

Take a look on Xamarin
Main idea - they brings real native code for all platforms.
They have instruments to compile C# code that it can be used at all platforms
For example you should create UI in XCode (for iPhone) and use ModoDevelop to create DAL/BLL, then you can re-use C# code base over all other platforms
They have cross-platform iPhone/Android/WP7/W8 samples on GitHub

We are starting to build multiple apps for multiple clients both in IOS and Android native platforms. The problem is we are going completely native which is taking too much time.
I would like to look at the linked in method (http://arstechnica.com/information-technology/2012/10/a-behind-the-scenes-look-at-linkedins-mobile-engineering/) which is a more hybrid approach using HTML and native code.
The problem is I don't think Phonegap is that good - good for prototyping but maybe not for full versions of apps as it can be a bit slow and a bit buggy.
I would like to look into doing a model where we create like 65% HTML and 35% native to that device (like linked in)
Would anyone have any suggestions for this? Would people say we need a massive development team to pull such an approach off?
I welcome thought:)
Thanks

Develop an sdk in android

Would like to develop an sdk in android for our client ,so need help regarding coding standards and practices that needs to be followed for it.
Please share your valuable comments.
As per the #user370305 comment, to create a native app you need to use Java. The best support software is Eclipse. Using Eclipse you can install the Android simulator which is very useful as you can test against all different Android firmwares.
When developing you need to take into account the many different screen sizes and resolutions, orientation etc.
Finally, if you like you can use something like phonegap to develop in HTML 5, CSS & JavaScript.
Hope this is what you were after.

does same code can work on both android tablet and ipad perfectly?

Hello friends I am an android developer and right now i am working on sencha touch framework on android platform to develop an app which can run on multi platform e.g android tablets and ipads.
But i have question in my mind that if i create my app on android tablet emulator according to the android tablet need(means layout configuration),will the same app work on ipad? or i have to work on simulator to make it work on ipad? Please suggest me with ur views.
Thanx in advance.
Most of the things works great for both of them. But there are some issues that you need to test on both the platforms e.g. Video Player for playing local videos on SD card.
Because, this generally is not a problem for iOS, but for android, you'll need your plugins. Also, from UI perspective, you must check on both the platforms. Since same CSS may or may not match. Happy Coding!
Native (i.e. Activity/Window) code is not compatible between the two platforms. If you develop using a web framework such as Phonegap, your differences will just be layout/CSS and plugin issues such as those mentioned by #Rajkiran.
You can also use commercial platforms such as Xamarin for abstraction of the hardware platform.

iOS and Android development on Windows

I'm facing a dilemma: I have a solid ASP.NET development experience in C# and looking to start mobile development. I have done research and know that there are some hacks for getting a development environment for iOS on windows, and recently after Apple lifted ban on 3rd party dev apps, Adobe Flash CS5 can be used to package iOS apps. I do have some prior experience with Flash and AS2.
So my question is: should i use Flash CS5 for iOS and MonoDroid for Android or should i just get Mac and learn Objective C for iOS and learn Java for Android? What would be the most practical solution?
Thank you in advance
EDIT: In the end, after trying out both Java Development in Eclipse against Android SDK and Mono for Android, I decided it's best to write Android apps in native environment. Eclipse FTW! As for iOS, I think it will also be best to use native Mac tools and Objective C.
While there are ways to get around using Objective-C for iOS development, I'm going to recommend that you learn it anyway. You need a Mac to deploy anyway, you might as well use it to develop as well.
Objective-C is bloody bizarre when you first start using it, with its strange square brackets and odd ways of doing things. However, once you've spent some time writing code in it, a change happens in your brainmeats and you suddenly realize that this is really an elegant way to work. Xcode is also quite an excellent IDE.
You can start with the iPhone Applications Programming lessons on iTunesU from Stanford. It's free, and covers what you'll need to know pretty throughly.
Worst case, you've learned a new language, and how Apple thinks iPhone apps should be developed. Even if you ultimately use something else, that understanding will help you out long term.
Take a look at monotouch & MonoDroid (Coming Soon), it still requires a mac. But you can open your solutions in VS2010 and use resharper, and just use the Mac for deploying and building. Take a look at this Here to open monodevelop solutions in Visual Studio.

For Android, I would recommend learning Java. I just started working with Android in Java on my Windows machine after developing some ASP.NET sites. I'm familiar with Java, but the syntax is so similar to C# that it's very easy to understand and pick up. So far it is more difficult figuring out and remembering the details of the architecture of mobile applications as opposed to the language. It also helps that there are a number of good books and online resources for converting from C# to Java and vice versa.
Update: I found a good post over on programmers.stackexchange.com that talks about C# vs. Java for Android development with good discussion on the pros and cons of switching: https://softwareengineering.stackexchange.com/questions/33076/as-a-c-developer-would-you-learn-java-to-develop-for-android-or-use-monodroid-i
#Dimitri I was almost your identical skill set when iOS 2.0 was released. I decided to try and learn Objective-C and now its my language of choice. Its a bit different to start with but most of the changes are simple to learn. Whether you are programming for iOS using Objective-C or something like Monotouch either way you have to learn the frameworks. If you use Monotouch you will never be able to be on the bleeding edge of the iOS enhancements. Using Objective-C you will be able to use the latest beta APIs and ensure your apps work right. You will need a Mac to deploy to the App store so just bite the bullet and get a Mac. Get a MacBook Air 13"
I went the route of Monotouch for iOS and Java for the Android. Unfortunately, Monotouch still requires a Mac. I am currently participating in the MonoDroid beta, which looks pretty promising too. It's all a matter of taste. I should also note that, for the most part, HTML/Javascript is a nice way to get portable apps in some circumstances. I would expect HTML5 apps to become even more viable as tooling improves.
I choose to use the Mono, MonoTouch and Mono for Android technology stack from Novell. When coupled with a micro framework like MonoCross (open source in Google code) it helps me write applications for both iPhone and Android devices while leveraging a shared code base for much of it. I would highly suggest the same route, it has allowed me to implement numerous solutions for small businesses and enterprise customers alike.
I didn't have the ASP .NET experience like you, but I was a Pocket PC/Windows CE developer so C# and the .NET Framework were also my strongest tools when I started on journey towards Mono many moons ago.
You can do iOS,Android and Windows using Xamarin.
Android and Windows can be done easily but doing iOS on Windows was tough so far like networked mac is required for debug and development but things have changed now.
Microsoft has introduced Xamarin Live Player using which you can debug,develop and deploy the app completely in windows without the help of any Apple system but to sign and release the app to appstore you will need Apple System though
