I had the same error happening and every time I fixed it, it would come back after I restarted Eclipse.

First of all, as other people said, make sure you do not have multiple copies of the same .jar file around your projects.

In my case, I had a main project that used ActionBarSherlock (among other library projects). The trick that worked for me was going into <code>ActionBarSherlock --&gt; Properties --&gt; Java Build path --&gt; Order of Export</code> and unselecting <code>Android Private Libraries</code>. Then going into <code>Project -&gt; Clean</code> and now you should be able to build the project correctly.

Now, for some reason, every time I restart Eclipse, it automatically enables that checkbox, so I have to repeat this process again.

Hope this helps some lost soul out there :)

I'm leaving this answer for someone who gets in this scenario as I did. 

I stumbled here and there before noticing that I mistakenly dragged and dropped the Support Library JAR file into my src folder and it was lying there. Since I had no idea how it happened or when I dropped it there, I could never imagine something was wrong there.

I was getting the same error, I found the problem after sometime and removed it. Project is now working fine.

blocks|key|520278|text|当同一个库多次添加到项目中时，就会出现此问题。如果你没有多次故意添加库，请检查你在项目中添加的库的依赖/私有库，很可能它们已经包含了导致这种冲突的库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|520279|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This problem occurs when a same library is added into your project multiple times. If you haven't added the library multiple times intentionaly, check out the dependency/private libraries of the libraries you have added in your project, most probably they have already included a library which is causing this conflict.

blocks|key|736819|text|我也在努力寻找这个问题。在我的例子中，发生的事情是在将apk复制到电子邮件(拖放)时-错误地将apk粘贴到了其中一个包的src文件夹中。在从源文件夹中删除apk后，它工作正常。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|736820|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

blocks|key|520369|text|我在Intellij中遇到了这个问题，这是因为我添加到我的项目中的ActionBarSherlock库将android-support-v4.jar定义为编译依赖，而这个jar已经包含在我的项目中，所以在编译时有多个副本/版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|520370|解决方案是将此jar的ActionBarSherlock模块依赖项更改为Runtime而不是compile，因为我的项目已经提供了它。|520371|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|$]]

I had this problem in Intellij and it was because the ActionBarSherlock library I added to my project defined the android-support-v4.jar as a compile dependency and this jar was already included in my project so there were multiple copies/version of DEX at compile time.

The solution was to change the ActionBarSherlock module dependency for this jar to be Runtime instead of compile, as my project was already providing it.

blocks|key|737059|text|为了添加无数的其他潜在来源...我已经更新了项目的lib文件夹中的所有库，但随后Eclipse“有用”地重新安装了所有原始库。在Eclipse中不再有任何对这些库的引用，但是外部的dex-maker程序只是抓取了lib目录中的所有文件，从而获得了几个库.jar文件的两个版本。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|737060|git+status识别出了新的文件，git+clean+-f帮我去掉了它们(尽管我有时不得不等待或在Windows上重启Eclipse，因为它仍然有从副本打开的文件)。|737061|entityMap^0|P|3|2Y|3|3I|4|0|0|A|J|C|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|I|$]]

To add the myriad of other potential sources... I had updated all the libraries in my project's <code>lib</code> folder but then Eclipse "helpfully" reinstalled all the original libraries. There was no longer any reference inside Eclipse to these libraries but the external dex-maker program just grabbed all the files in the <code>lib</code> directory and thus got two versions of several library <code>.jar</code> files.

<code>git status</code> identified the new files and <code>git clean -f</code> got rid of them for me (though I sometimes had to wait or restart Eclipse on Windows because it still had the files open from the copy).

ULTRA simple solution and finest:

Remove everything in Right Click Main Project's Folder -> Properties -> Java Build Path except Android X.Y (where X.Y is the version in android). Clean, and Build. Done!

Make sure before of that to have a single android-support-v4.jar.

I know this question has been asked here a few times before. But i haven't seen any possible solution yet.
Before i make the project 'Run as Android Application' , if i do not clean it, i receive the following error and have to restart Eclipse ... and clean again.

<pre><code>Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define
 Lcom/jstun/core/attribute/MessageAttributeInterface;

com.jstun.core... is a part of my src folder, of course i can't remove it. And even if i remove that package, another package will show up as an error like:

<pre><code>Unable to execute dex: Multiple dex files define
 Landroid/support/v4/app/ActivityCompatHoneycomb;
</code></pre>

I've seen this error since updating to ADT 15, i'm using Eclipse Galileo on Ubuntu
Do you have any idea? Thanks for any reply!
