i am new developer here, write now i am develop application
using blackberry web/widget (eclipse) and the language i used is phonegap where phonegap support .html, .css, .javascript. so i want to know how my application work? is it
depend on os version or phone model or both?
thanks.
regards,
jamaley.
You develop with phonegap.
This is a framework that let's you create mobile apps with access to phonefunctions by using web standards.
You will need to compile your app for each platform (OS). Seperatly.
Of course you will need to take in mind the different resolutions for each phone.

I have a requirement from client to develop an iPhone application. As I am a dot net developer I thought it will be bit challenging for me. So I thought of developing it using phone gap. So before suggesting something to the client I need to make sure of certain points.
Do I really need a mac machine to develop this?
Since I am using only html5, css and js, can I develop it in Visual studio/Eclipse? I have already tried some samples in both these IDE. And once the app is ready I have read about using PhoneGap Build I can make it ready to use in iPhone...
But from the following link, what I understood is I need an apple computer, mac os and Xocde to develop it even though it is not a native mobile app.

Please guide me with some insights before talking to the client.
Thanks.
PhoneGap Build is a cloud-based service built on top of the PhoneGap
framework. It allows you to easily build those same mobile apps in the
cloud. To get your application build just what you need is to simply
upload your web assets - a ZIP file of HTML, CSS and JavaScript, to
PhoneGap Build, after some time you’ll receive the download URLs for
all mobile platforms.
I read it from here , they also mentioned about installing SDKs
you might want to install some of the SDK emulators if you don’t own a
particular device that you want to test a build for.
Here in this link they have put a note
Since PhoneGap Build uses Apple's standard development process to
build applications, you will need to sign up for their developer
program to build iOS applications on PhoneGap Build. You will also
need a Mac to configure your certificate and provisioning profile.
Consider using a Mac Virtual machine.
You mainly need a mac to create key value chain pairs to sign your app and test it on a device. You can just get a Mac VM to do this is my recommendation. You can then use the phonegap build service to compile your www folder for iOS
Here is a good demo for multiple index files to have one solution base

I think you should do a bit more research before jumping into bed with PhoneGap for the sake of not being an Objective-C developer. PhoneGap has its limitations, and my experience of it compared with native app development is pretty poor.
I'm new to Titanium and PhoneGap and analyzing a bit the two is not possible to develop iPhone with a PC with windows using either of the two right? Well I mean in PhoneGap in the most current versions is only possible to develop without publication.
I wonder if this is actually correct and whether there is a way to make an application to one of these two technologies (Titanium and PhoneGap) Fragment as a view of the native Android devices for both Android and iPhone / iPad. Improving question, make an application to view the devices can be adapted for smartphones and tablets for better use of the screen?
If yes there is some example code and/or source of research?
PhoneGap has an offering called PhoneGap build which just came out of beta. It lets you build your apps in the cloud without a Mac.
You might still need a Mac for certificate (p12 bundle) generation or you can use a service like Mobundler.
For Titanium, a recent service called Foundry22 lets you build your apps without a Mac or any native SDKs installed locally. You just need Titanium Studio and a hosted Git repo.
I have an android project that targets Android 2.2 (developing in Eclipse). Exporting the android project to the Droid Incredible works perfectly. Is it possible to export the project to a file suitable for installing on an iphone? I know that most iPhone apps are developed using xCode, but I'm not sure if xCode packages into a .apk or other file format that's equivalent.
Thanks in advance.
Only if you write or port your own complete Dalvik VM (in Objective C or Javascript), plus developing the runtime support needed for any and all API calls that your app uses, and bundling all that with your app, as that would be the only way to run a regular Android project on an iPhone.
A non-trivial amount of work.
Completely rewriting the app in Objective C and Cocoa Touch would be magnitudes easier.
Not even remotely possible. Android and iOS are completely different environments. There are a few frameworks for developing applications that'll run on either, but the results often end up looking kind of weird on both platforms.
You cannot export an Android application and run it in an iPhone because the hardware/software stacks/APIs/etc. are different.
However, if you build an application using for instance PhoneGap (a HTML5 based application framework), it is possible to deploy it on different mobile platforms.
If you feel curious about multi-platform mobile frameworks (Android/iPhone) you may find this thread interesting.
Can we build an iphone app and convert the application to the android application using phonegap framework?
I have been through various links.
We basically need to develop a webapp for that and that can be converted to an android app or an iphone app respectively.
I am an iphone application developer and i am not at all familiar to android.
Links or example code would be greatly appreciated.
PhoneGap will not enable you to "port" an existing iphone application to Android. However, if you develop an application within the PhoneGap framework (which means using html, css and javascript), you will be able to deploy it on multiple mobile platforms such as iPhone, Android, Nokia, Blackberry, etc.
The downside is that you will eventually be developing a packaged mobile website - your application consist of html pages, css styling and javascript behaviour/logic, combined whith access to phone internals such as gps, disk, database, camera, etc. It will usually not "feel" fully native on most platforms. For example, you will not be using the system's "native" ListView.
There are javascript libraries such as JQuery-mobile, JQTouch, etc, that make your application look nicer on mobile devices, but it's still not as good as the native experience.
The app you build will not be a native Android or IPhone app but a HTML Web App wrapped in the PhoneGap wrapper and packaged into a native app. So yes you can build for both platforms as long as you build a Web App
Edit -(a Web App is just a plain html/css/javascript + server-side(php, asp etc) website)
Recently we are going to develop some products on mobile phone (specially for 3g). There are many platforms about mobile phones: iPhone OS, Symbian, Blackberry's. If I want to develop a product, should I use Java or write every program for the main platforms?
Particular one question for iPhone development: are there many Java programs on iPhone? Most iphone app I've seen are developed by their own xCode.
I need some guidance on how to do coding for mobiles correctly.
All these platforms are completely different beasts as in the old days. About symbian, (which I am most familiar with) you can use Qt for quality native applications. Native api is confusing so avoid it where possible. If your application is simple, you can even get away with python.
In short, use the language which you are most productive available for each platform. Their apis are wildly different anyway. Language choice doesn't matter as much as the choice of platforms you are supporting.
Java is not available for use on the iPhone; you can use Objective-C, C and C++ to develop iPhone applications.
There is currently no Java for iPhone, so you need to develop separately for iPhone in objective C.
Alternatively you can create application which runs in web browser, it'll be available on all platforms, but not every application is suitable for web.
Have you considered you using web technologies?
There are a couple of cross platform tool kits for iPhone and Android. They work in the same fashion as Adobe Air. Allowing you to make HTML/JS based web app and run it as native code in the browser.
Titanium Mobile (Android & iPhone) HTML/CSS/JS
Corona iPhone Only via Lua
Palm's Web OS is also based on web technologies.
Finally the old guard, Symbian Provides a Web Widgets system, that works in on all handsets with 9.2 fp 2 installed (n95,e72, n97 etc.) The api supports some hardware functionality.
The only one left out in the cold is Windows Mobile. There is some 3rd party support in the form of Web Widgets by torch mobile
It's currently limited to iPhone, BlackBerry, and Android (and possibly WinMo) but you may want to check out the open source project called PhoneGap. I think it is basically just a native wrapper around the built in web browser for each device, but it does expose some functionality not normally available in that environment such as geolocation, accelerometer, sound, etc.
