Im new to the development of apps and i've got some questions.
First let me tell you about the app i need to make.
As an intern at a company i need to develop an iPhone and Android app, they want me to create an app that is based on a existing CRM database.
I need to get data from the database and show it on the iPhone, this data should be edited and send back to the database.
The company itself does not has experience in the development of mobile apps.
EDIT:
The requirements i wrote above are the basic of the application, it will have alot more functionality implemented after the basic has been made. Something like an auto sync, either the database or phone will sync with each other once in a while. And when you are called on the phone it will also check the number in the database and if found the name is displayed instead of an unknow number. Just 2 things that should be implemented after the basic app
Is such a thing possible with an iPhone/Android?
As i have no experience with Objective-C, and little experience with java
Is it easy to learn, i have good knowledge of C#
What platform could you suggest for me?
As i need to develop for both iPhone and Android,
What is the quickest way of developing for both at the same time?
i've done research but as i do not have an mac at the moment i can't try stuff out for the iPhone.
Titanium Appcelerator is something i liked, and since this works for both iPhone and Android i think this might be a good option. But as i do not have any experience i want some good advice from those who have experience before i start programming.
tnx in advance,
~kamikze the rookie
You can also try PhoneGap.
You can use web services to connect to databases
As per your requirements, use Titanium Appcelarator, which will make you write your code in JavaScript, and will generate apps for both, iPhone and Android.
What you're wanting it to do is fairly simple and shouldn't introduce a lot of complexity before you.
Go ahead with Appcelerator, if you don't want to spend a lot of time learning Android SDK and Objectiv-C
It sure is possible to access/change databases.
If you have good C# knowledge then getting started with Java should not be an issue for you.
I think it should be quite easy to implement for Android, but I also have no experience in iOS development (don´t have a mac)

Titanium claims it can do the same app on average 70% faster than native XCode.
What's been everyone else's experience in terms of difference in speed of development （between native XCode and PhoneGap or titanium) ?
Let's say an app like Kik Messenger or Badoo ....
Typically, a good XCode developer can do it in 4-5 weeks, assuming graphics and backend are in place.
What would it take for an experienced Titanium (HTML5) person to achieve this? (roughly)
Time to market depends on quality of specifications, process and people, much more than the underlying technology or framework.
Coding a real application with Appcelerator Titanium is not that easy, and runtime performances are SLOWER than native code because it's using a javascript engine as a bridge. Especially with a big TableView, it's much more slower, and the feeling is just not the same. But once you have purged the memory leaks, the feeling is nevertheless incredibly better than with HTML5.
You should be interested in Titanium or PhoneGap(now known as Cordova) if you plan to distribute your application on other devices or if you really don't like Objective C.
If not, keep it with the Native Xcode.
I would add that Cordova will not make any UI, but let you access camera, accelerometer or GPS with javascript inside HTML5 code. You would probably use Sencha Touch or jqueryMobile with Cordova.
In my experience, if the app is not a simple template app then you would be better advised to create a native app for each platform.
As Rob says, trying to overcome the lowest-common denominator situation and overcoming limitations in cross-platform "solutions" usually means it takes longer to code than doing it natively in the first place.
You might even hit a problem which causes you to abandon ship and start from scratch as native apps. So if you decide to go a PhoneGap or Titanium route then make sure you research fully before starting and that you won't have future requirements not covered by them.
If you are an iOS developer and you are developing it only for iOS device, then it is better to code using XCode. If you are more into Javascript and developing for both android and iOS then you should use Titanium or Phonegap. Between Titanium and Phonegap, I found it easier to code using Titanium(and yes fast as well). But I am not sure how much worth is using Titanium. http://usingimho.wordpress.com/2011/06/14/why-you-should-stay-away-from-appcelerators-titanium/
I'm actually performing a fairly intensive survey of all the major cross-platform mobile development kits right now. I started by making a sample application from scratch in IOS that uses a few simple device features, and then reimplemented that as an Adroid app. Both of those took about a day to complete (the android took maybe half a day longer). Since I've never written an android app before, I think that's a good baseline in terms of comparing development time between the various other frameworks I'm testing out.
I'll update this comment in a few weeks with a blog post when I'm done, but for the moment I've been finding that these cross-platform kits are vastly more difficult to use and take a lot more time, even for the simplest applications. and despite this, there's still quite a bit of custom per-device code that has to be written for UI and fundamental idiosyncratic differences between how device services function, so you don't really get the value of a true "single code base" that you may have been expecting.
I think the main value in these may turn out not to be anything related to development time or code reuse, but instead only as a way for non-app-developers to create simple prototypes that can later be handed over to the "real" mobile developers to be built out into true native apps afterwards... Not really all that useful in my opinion, but maybe my thoughts will change as I delve into this further.
Appcelerator is not HTML5, it is a native app built in a higher level language of JavaScript. It abstracts the complexity of common elements away and provides huge value, ping me offline to know more. I run our California business.
I am a C Sharp.NET & Silverlight developer and now thinking to swicth to SmartDevice development specially for iPhone & Andriod based phones. I have looked over web and found some cross platform development frameworks like
http://developer.openplug.com
http://www.phonegap.com/
http://android.xamarin.com/Welcome
but not sure about which to choose. Naturally I would like to keep my learning curve less but also would like to choose platform which provides more power, so I am looking for your suggestions and 'Getting Started' tips and also which device you think will be in demand in future iPhone or Android ? .
Thanks,
Maverick
I wouldn't recommend any of those. The problem is, that those "cross-platform" development frameworks, still aren't cross-compilable. This means you still need to develop an application for each platform, but you can reuse heavy calculations if you are using models af MVC.
Another thing is that those frameworks still aren't 100% native supported, so you'll loose some features from the native frameworks when developing applications.
I've read a lot of articles and to be honest, these cross-platforms seems to be dying out, cause both Android and iOS are moving very fast in each their direction and the cross-platforms cant keep up. But it's still up to you.
In would recommend you to choose one of those platform and learn it from scratch. With your C Sharp background, maybe iOS and Objective-C would be the most natural choice.
Enjoy
Edit: Regarding you last question:
I dont think it matters which one you choose, both will be domination for a long time. You should pick the one you can identify yourself with.
since you are C# dev, go for MonoTouch. I heard good things about it.
Miguel de Icaza is behind Xamrin. He wrote the most prolific .NET platform for UNIX, mono. I believe both he and his team have the capacity to bring you the most coverage for common features on Droid and iOS. My friend has a startup and is releasing an app shortly for iOS on Xamrin. It is a video streaming app.
HTML 5 will get you the most cross platform for the investment. Of course, like everyone else has said, if you need lots of native integration or if you want to use the latest APIs upon availability, you have to go native.
I have developed an app for the Android and it's working well, finally, and thanks to all the help from StackOverflow!!
Now I am being asked to make it work on the iPhone. I looked at iPhone a while ago but not recently.
What does everyone think? Should I take the time to learn Objective C and iPhone and port the app or forget it?
Are there any books that cross-reference functions so that you can look up how to do something in iPhone that you already have on Android?
From my experience in school, if you have already been able to create a working smartphone app in at least one mobile OS such as android, it wont take long before you can understand objective C and cocoa framework stuff. The only problem with that is you may probably need an apple developer license to use XCode.
So, I would say go for it since you also get paid, and also here is a link to iphone development guide for android developers : http://integratingstuff.com/2011/02/27/starting-iphone-development-as-an-android-developer/
Probably, it's better to get a partner who develop to iOS than doing it yourself.
Focus on a platform and let your products run to all users.
Unless you are using a framework that supports both iOS and Android (something like the Corona SDK) you won't have much actual code that will transfer over. Ideas, algorithms, logic, graphics, designs, etc will all transfer over just fine. Those are the hardest parts (IMO) of software dev.
Objective C (the language iOS apps are written in) is not that hard of a language to learn if you already know C-based languages (like Java). There are a few concepts that are different, but for the most part, it's not that bad. The biggest challenge for developing on iOS is buying a Mac. You can program for Android on Windows or Linux boxes, but iOS apps can only be developed on an Apple. Unless there is something that has happened in the Hacintosh arena that allows for iOS development on other platforms, you're stuck buying new hardware. BUT if you already have a Mac, download XCode and go to town!
Like Haphazard said, if there is enough money in it to make it worth your time, do it.
If you are getting paid, go for it! (Also, it could be a great learning experience.)
When I had to make the same decision, I considered the following criteria:
how much money is in the app on the other platform ?
how many times will this happen in the future, or is this going to be the only app? (how big is the benefit of learning the other platform for the future)
how much insider know-how is in the app that one is willing to reveal to another programmer porting this app (in my case I do mostly device handling apps, which is not really all that common)
what is the opportunity cost of spending time on porting an app instead of developing another profitable on the initial platform
If you have any possibility, you may look into similar apps and see how they are doing on the two platforms...
Good luck, whatever you are going to do...
I just learned about this and have not tested it yet, but one thing that you could do depending on the app you have you could take a look at PhoneGap. It looks pretty promising, though it may not work for your case with your initial application already made. But in the future this could help.
Unfortunately you will either have to re-write the app from scratch for iOS, or hand over the job to an experienced iOS developer. You can fairly easily port over the logic and computations in your app from Java to Objective C, but the user interface is the area where you cannot really re-use anything (except maybe icons), and the user interface tends to be a large portion of most apps.
As an Android developer who has ported several of my apps to iOS, I can say that this transition is a hard one. Firstly, you need to buy an iPhone and a Mac (if you don't already have these), since you cannot develop apps for iOS without the Apple hardware. Secondly, you need to learn how to use XCode and Objective C or Swift. And thirdly, since XCode ONLY allows creating the user interface graphically (as opposed to Android which lets you hand-edit the XML), there are many hidden things which can cause you to come unstuck. (UPDATE: Using the new SwiftUI approach to user interface design really helps with this last point, and in my opinion makes the transition from Android to iOS easier).
Finally the Apple and XCode environments seem rather alien to someone who is used to Windows and Android Studio. There are things like the Home and End keys having completely different behaviors to Windows which is frustrating. Also you have to use a combination of key shortcuts and mouse movements to hook up user interface elements to your code. Also, there are big annoyances such as the pop-up keyboard on iOS not pushing the content out of the way automatically like it does with Android. This is probably because Android is an OS designed for multiple screen sizes, whereas iOS is design for a limited number of screen configurations, but it makes iOS feel inferior and harder to work with from a developers point of view. (UPDATE: Using a ScrollView in SwiftUI solves the keyboard obscuring problem).
Hey all, quick question. My end goal is to start developing apps for the iPhone but my current skillset is pretty limited. I'm wondering how far back I should go back and where I should start as far as becoming familiar with coding before the iPhone SDK course on Lynda.com isn't something that makes my eyes glaze over.
My experience: I taught myself html from the html for dummies book maybe 10 years ago, I've taken a dreamweaver class and built a few sites with it, and I've customized a self hosted Wordpress blog by playing with the php code.
Any tips on where I should start if I want to head down the road toward developing for the iPhone? Thanks!
If the iphone is what you want to do then I would recommend starting with the iPhone SDK and some samples. Deving native apps iPhone is pretty different than HTML - it is mostly Objective C where you have to worry about memory allocation/cleanup and pointers, but the quickest way to find if you like it or not is to download the free SDK and try it out.
If you find you don't like it, the browser capabilities on both iPhone and iPad are pretty advanced and I have seen some very good browser based apps built using web technologies.
I put together this list of resources for learning iOS Development:

Hope that helps!
Am looking into developing an iPhone native app using Titanium Developer
Since this is still in beta, I am wondering if there are any better options and/or if its a good idea using such software to develop native apps (which are not games; not graphic intensive)
If you don't want to wait, you can do what a lot of us did: develop apps in Cocoa Touch. It works perfectly well for games as well as non-graphic intensive apps.
The similar and more mature PhoneGap framework has been used in a number of iPhone apps and Apple only seems to object if the application autoupdates.
That being said, I wouldn't recommend using web frameworks unless your application is really simple--you will get a much better experience from a native application (on both Android and iPhone)
My company uses Titanium and it's working fine so far. It's also a pleasure to develop iPhone app using javascript and co. I'd recomend you give it a try, it's really simple to set up and start coding.
