Converting iPhone/iPad apps onto Android [closed]

Answer 1

You may be interested in reading my book, HTML5 for iOS and Android, which enables you to take web apps created in HTML, JavaScript & CSS, and turn them into standalone apps that you can upload to the app stores (for free or to sell). See http://html5formobile.com - the wrappers to do this for the iOS and Android SDKs are freely available on the website, and you don't need any knowledge of either programming language if you follow the instructions in the book.

Answer 2

You can't just convert iOS apps into Android. iOS is Objective-C and Android is Java.

I highly doubt there are 'converters' on the internet, even if there are that's not the way you should program an app because every SDK has his own special capabilities and you should use them for maximum user-experience.

I'm sure there are some companies who specialize in porting apps from iOS to Android. Look it up on Google I'd say..

Answer 3

No, there is no way to convert an existing iOS app to an Android app.

However, there are cross-platform frameworks that allow you to code once and deploy your app in more than one platform. The most popular are based on HTML/CSS/JavaScript and one of them is PhoneGap.

You can also develop for iOS and Android with Adobe technologies such as Adobe AIR (this was forbidden by Apple until recently).

And there are online services (such as Mobile Roadie) that allow you to generate cross-platform apps using a content management system.

That said, I strongly recommend to:

• Learn Android and Java development if you want to specialize in mobile development.
• Take advantage of the strengths of each platform when working on an iOS/Android project, instead of creating something that uses only what's common to both.

Answer 4

Due to the massive differences between the 2 platforms, you are looking at a complete rewrite of your application. You either do it yourself or pay someone else to do it. I don't see any shortcuts you can take.

Answer 5

Even if there was a way to easily port an Objective-C application to Java, I wouldn't highly encourage it. iPhone users and Android users are two different families of users. The typical iPhone interface just wouldn't sit well with Android users who aren't familiar with how the iPhone works. Yes, I understand that the UIs of both iPhone and Android seem pretty trivial to learn to most people, but when you break a novice's comfort zone, it puts your applications (or websites) on a higher learning curve.

You should take the time to learn Android's language and UI and develop your application in a fashion that is consistent with how applications on Android work. As said in other answers, if your taught yourself Objective-C, you should find that Java will come pretty easily to you. In addition, in never hurts to know more than one programming language.

Answer 6

Selecting a mobile development environment which will enable you write once and deploy/distribute it on many devices would be a better solution in the future. If your application is HTML-based, go with HTML5/CSS alternative (ex: PhoneGap, ). If you prefer native, then chances are you may want to learn Lua, a scripting language (ex: Gideros Studio) or C++ (ex: Mosync).

Other than that, the application you created on iOS with Objective-C is very, very hard to port to Android and other devices.
