There's nothing of the sort to port your app. You can use 3rd party tools to create apps that work in both. That's what <a href="http://www.appcelerator.com/" rel="noreferrer">Titanium</a> and <a href="http://phonegap.com" rel="noreferrer">PhoneGap</a> were aiming at. With the new changes to the SDK Agreement, those look like they're not really "legal" or at least violate the agreement.

As for your other question, yes, people do create 2 separate apps. One for Android and one for iPhone. That's the way I currently do it and seems as if Facebook and others do the same.

blocks|key|1083088|text|是的，人们通常不会喜欢我们在Appiction上对这个问题的回答。这看起来应该很容易，因为它们是如此相似，但它们是完全不同的操作系统，有不同的使用方式。有时，一家公司能够与你达成交易，因为艺术已经开发出来，基本的线框已经构思好了。在Appiction，我们制作了一段视频，为我们的客户回答这个问题：http://www.youtube.com/watch?v=Y-fdRw1WNYI|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1083089|entityMap|0|LINK|mutability|MUTABLE|url|http://www.youtube.com/watch?v=Y-fdRw1WNYI^0|45|16|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Yeah, people don't usually love the answer that we have for this one at Appiction. It seems like it should be easy since they are so similar, but they are completely different operating systems with different ways of being used. Sometimes a company will be able to cut a deal with you since the art has already be developed and the basic wireframes have been conceived. At Appiction we created a video to answer this exact question for our clients: <a href="http://www.youtube.com/watch?v=Y-fdRw1WNYI" rel="nofollow noreferrer">http://www.youtube.com/watch?v=Y-fdRw1WNYI</a>

There are few alternatives to port an app from one platform to other. like Rhodes Mobile, Titanium and PhoneGap. In fact they did a good job and tried very well to remove fragmentation in smart phone app development. 

But according to Apple's SDK Agreement version 4.0, <a href="http://daringfireball.net/2010/04/why_apple_changed_section_331" rel="nofollow noreferrer">section 3.3.1</a>

app must be developed in C/C++/JAVA script. 

At this stage convincing way is to write it separately.

blocks|key|1638241|text|移植确实没有捷径可走。您能做的最好的事情就是使用专门从事移植的公司，比如migration.mobi。跨平台框架存在性能问题，并且确实限制了您的能力。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1638242|游戏是完全不同的故事，所以如果你在iPhone上是一个复杂的实时游戏，并且你想让它在另一个平台上工作，那么请准备好接受不同的答案。|1638243|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

There really isn't a short cut to porting. The best thing you can do is use a company that specializes in porting, like migration.mobi. The cross-platform frameworks have performance problems and really limit what you're able to do.

Games are a different story altogether, so be ready for different answers if you've been a complex real-time game on iPhone and you want it to work on another platform.

blocks|key|1086872|text|PhoneGap不是一个真正的跨平台应用程序开发工具。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1086873|如果你想使用PhoneGap同时为iPhone和安卓创建一个应用程序，那么你必须创建两个不同的应用程序来使用PhoneGap框架。但PhoneGap不能为iPhone和安卓创建一个单独的应用程序。|1086874|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

PhoneGap is not a true cross platform app development tool. 
If you want to create an app for both iPhone and Android using PhoneGap, then you have to create two different apps that will make use of PhoneGap framework. But one single app for iPhone and Android can't be created using PhoneGap.

<a href="http://www.noodlecake.com/555/noodlecake-studios-to-ease-the-pain-of-releasing-on-android/" rel="nofollow">Noodlecake Studios</a> appear to have solved the issue of porting from iOS to Android, recently porting Trainyard among others:

<blockquote>
 Its no secret that the process of porting iOS games to the Android
 platform has been met with rough waters... These issues are
 familiar to us at Noodlecake Studios and prompted the creation of
 Noodlecake Games, a porting and publishing entity designed to
 alleviate many of these problems. Through our efforts over the past
 year, we have developed technology that allows us run iOS code
 natively on android devices. What that means for developers is there
 is no need to rewrite iOS code for the Android platform, it all runs
 automatically. To be expected, many developers at first didn’t believe
 what we were doing was even possible.

At android there are 2 categories: the lower one, with g1 and the better with Nexus 1 if you want to develop games.
Those cross platform libraries I think they can do cross platform "Hello word" applications.
To generate a correct Blackberry networking application or an optimized Android graphic application (to both categories), I highly doubt it!

<ul>
<li>the frameworks has the big cons, when you want to look outside of the sandbox. Those 3-4 custom stuff, plugin often cost more, than the whole application written fast until that point.</li>
</ul>

So, "Hello word" +very basic, only soft stuff with cross platform.
High performance, nice graphic, easier to bugfix, support, professional work: develop for each platform and categories.

blocks|key|3046738|text|实际上，有一种工具可以完全按照您的要求进行操作，它的名称是O2J。您可以利用现有的Objective-C代码库，并使用O2J转换工具将其转换为Java。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3046739|这是Mac+app+Store上的付费应用程序...O2J+Objective-C+to+Java+Converter|offset|length|3046740|大多数情况下，最好使用原生UI和原生代码来提高性能，使用平台UI范型并利用特定于平台的API/服务。|3046741|entityMap|0|LINK|mutability|MUTABLE|url|https://itunes.apple.com/us/app/o2j-objective-c-to-java-automatic/id988532240?ls=1&mt=12^0|0|Q|X|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

There actually is a tool that does exactly what you're asking called O2J. You can leverage your existing Objective-C codebase and convert it to Java with the O2J conversion tool. 

It's a paid app available on the Mac App Store... <a href="https://itunes.apple.com/us/app/o2j-objective-c-to-java-automatic/id988532240?ls=1&amp;mt=12" rel="nofollow">O2J Objective-C to Java Converter</a> 

Most of the time it's preferable to have a native UI and native code for performance, working with the platform UI paradigms and to take advantage of platform specific APIs/services.

What is the most efficient way to port an iPhone app to Android? I know Apple doesn't like 3rd-party, non-Objective C platforms generating code for their platform ... but is there something out there that can take an iPhone app and convert it to Android friendly code?

If not, how have folks out there been creating Android versions of their existing iPhone apps?

Thanks

将iPhone应用移植到Android最有效的方法是什么？我知道Apple不喜欢第三方的、非目标的C平台为他们的平台生成代码……但是有没有什么东西可以把iPhone应用程序转换成安卓友好的代码呢？如果没有，人们是如何为他们现有的iPhone应用创建安卓版本的呢？谢谢
