I am using facebook-unity-sdk-7.3.0 and GooglePlayGamesPlugin-0.9.32 in my project. it does not let me build for android and fails with error 'Unable to convert classes into dex format. See the Console for details.'. It starts working again when I delete any of the sdk fb or googleplay from my project.
Console error

I did some research on it and found that this issue is related to two same jar files in the project but in my project, I unable find any duplicate jar file.
Edited
for reproducing the issue, I have made a sample project which can be downloaded from here http://wikisend.com/download/966354/LeaderboardTest.zip
Go to Assets->FacebookSDK->Plugins->Android->libs then delete android-support-v4.jar. There is a conflict there because it contains a class from another jar or aar file.
'Unable to convert classes into dex format. See the Console for details.'.
this one shows up when a class/dll exists twice in the project.
Often it happens when updating framework, if you do not remove the old version properly, then some classes may appear twice.
Since they are stored in plugins folder, Unity does not check them and they only show up in build process.
Best could be to remove everything related to both plugins and reimport them. That solved it for me when using UniWebView and Vuforia in same app. One of those was not properly updated.
In my case I could solve this problem by removing Android SDK Build-Tools version 24 and replacing it with version 23.
Maybe it's too late to answer, I was facing the same issue, I created a plugin this plugin contains Facebook SDK+Admob+unityads +unity IAP, all of them work together, I've created this plugin in unity 5.6.0, but I've checked it, it is working fine in unity 2017 as well, there is a scene "DemoScene", just open it everything is implemented, unity ads, admob, facebook share with callback, unityIAP.
Note: before importing the plugin kindly delete all the old plugins, also go to services and turn on unity ads.

i'm following this tutorial from firefox android source code https://wiki.mozilla.org/Mobile/Fennec/Android
but, the problem i can't ./mach build, ./mach package, ./mach install and i already create .mozconfig file in mozilla-central but it's can't found the file.
like this:
i'm using Ubuntu 14.04.2
thx for help
You probably had an error during the initial "mach bootstrap" step. Your screenshot tells us, that mach can't find the android sdk tools. It's looking for them under ~/.mozbuild/android-sdk-linux/.
One thing you could do is to manually put your sdk under that directory and then retry "mach bootstrap" from the source dir to resolve the remaining dependencies.
Also see these steps for manual setup of the build tools: https://wiki.mozilla.org/Mobile/Fennec/Android/Detailed_build_instructions
In my app, I have to have two version: Full and Lite.
I am following these tutorials:
http://bitowl.wordpress.com/2011/07/06/tutorial-how-to-make-full-and-lite-versions/
http://blog.donnfelker.com/2010/08/05/howto-android-full-and-lite-versions/
So, I build my full version, and make it a library. This full version uses some other libs, needed to some components.
Then, I create a new project and added the lib created. The problem is when I try to run my lite version, eclipse gives this error:
[2012-12-13 13:58:13 - <app> Lite] Dx
UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Lnet/simonvt/timepicker/R$attr;
Conversion to Dalvik format failed with error 1
The simonvt/timepicker is one of the libs that I use in my full version.
How can I fix this?
Thank you!
Do the following:
Right-click on your project and choose Build Path -> Configure Build Path,
then go to order and export section
If simonvt/timepicker has a checkmark against it, then deselect it.
I believe that the problem is that the library project is already added and you might be trying to add it again.
Trying to run my Android App and Eclipse (in Windows 7) is throwing up an error. Yesterday I had no problem so I can't think what I could have done to caus eit. The error message is
**Your project contains error(s), please fix them before running your application.**
Well, I went to window->view->error log and I found this

I would like ot add that although the project itself is showing an error no source file or resource has an error.
SO far I have tried:
clean/build (several times)
close eclipse and reopen (several times)
shutdown computer and restart
Thanks in advance.
EDIT:
Tried again and got the following message in console:
[2011-08-14 00:40:47 - Dex Loader] Unable to execute dex: wrapper was not properly loaded first
[2011-08-14 00:40:47 - MyAppName] Conversion to Dalvik format failed: Unable to execute dex: wrapper was not properly loaded first
Don't know it cant convert to Dalvik format. The SDK is in the build path.
After much stress and pain and me almost throwing my computer out the window I found the problem is in the debug.keystore file. Although Eclipse gave me no warning of this. After deleting the debug.keystore file I cleaned/build my project.
Eclipse gave the following error.
Re-installation failed due to different application signatures.
[2011-08-14 13:16:42 - MyApp] You must perform a full uninstall of the application.
WARNING: This will remove the application data!

I didnt follow the advice but simply renamed my package. It works now. I'm not sure what to do with older packages that I have released onto the Market. It will be difficult to add new versions if I have to rename them to test them on the emulator/my phone.
feels to me something wrong with the SDK. Why dont you uninstall the current Android sdk and install a new version instead.
Right-click on your Project in Eclipse and choose Properties. Check in the Java Build Path that you have the Google API's in the Libraries tab. Check the references to them.
Encounter this problem when trying to Build Project getting such output in console:
[2010-07-19 23:29:23 - myProject]
trouble processing "javax/net/SocketFactory.class":
[2010-07-19 23:29:23 - myProject]
Attempt to include a core VM class in something other than a core library.
It is likely that you have attempted to include the core library from a desktop
virtual machine into an application, which will most assuredly not work. If
you really intend to build a core library -- which is only appropriate as
part of creating a full virtual machine binary, as opposed to compiling an
application -- then use the "--core-library" option to suppress this error
message. If you go ahead and use "--core-library" but are in fact building
an application, then please be aware that your build will still fail at some
point; you will simply be denied the pleasure of reading this helpful error
message.

I was looking for my project to use the package javax, not found, clean all also does not help. what I am doing wrong?
Update
Sorry guys, but I could not find good fix for that, I want to emphasize the fact, that i dont use SocketFactory class in my project at all! source code was not changed before this problem, and that's why i think that problem in eclipse or adt or something else, BUT if i use ant(generated by sdk) to build this project there is no problem!!!
I solve this problem by removing Eclipse, Android SDK, Eclipse workspace, and just reinstall them, after this all works fine for now.
Hope this will help someone.
I had the same problem..
This worked for me
project-->properties->java build path->libraries-> remove all including android jars
now go the project browser, right click on the project you are working on,
then android tools---> fix project properties...
do a clean and then build...
I solved the problem (at least for me).
Here's what I did:
Go to Project » Properties » Java Build Path » Libraries
Remove all except the "Android X.Y" click OK.
Go to Project » Clean » Clean projects selected below » select your project and click OK.
That did the trick for me.
Hope it works for you as well
Update: well actually I might have to retract my opinion.. the actions removed the error messages but now I am missing certain classes and methods... arggghhhh
I just restarted Eclipse, and the error didn't appear anymore!
I had the same problem,and solved it as follows:
First clean all jars; (This problem must because your some jars)
Delete the project;
Reimport project;
Make sure your sdk is right, and project select one sdk version;
(This is my issue to solve the problem) Right click your project, and select "build-path", next select "add Librarys", and add your private jars;
clean-build, the problem has fixed;
I just had the same problem and I tried all of the solutions listed here with no success (I was starting to get annoyed). Then I removed the project from the workspace and then imported it again, and there were no problems!
This happened to me this way,
I have a quite an old project which I had to start working again today. I use 'Universal Image Downloader' library for basically every project where I have to deal with lots of images. So in this old project I had the source files of 'Universal Image Downloader' included to it's 'src' path. Back then I was a newbie and slowly I started developing my own library which could handle every day simple Android development tasks very easily. Obviously I included the 'Universal Image Downloader' to this.
After dusting off the old project today the first thing I did was to reference my library to speed up the development process but as I was trying to debug I ran into the "Conversion to Dalvik format failed with error 1" over and over again. First I thought it was the support library but even after clearing all libraries and adding only mine and doing a quick 'Fix project properties' I still got it. After trying various solutions I noticed this in the console "java.lang.IllegalArgumentException: already added: Lcom/nostra13/universalimageloader/cache/disc/BaseDiscCache;"
It was as simple as that... I'm trying to compile a class which has already been compiled.
Solution : I just simply removed all the class files I got from 'Universal Image Downloader' library from the 'src' directory. Since my library references "Universal Image Downloader" library the old project started working just fine.
Hit same problem shown on your log when trying to run an example project which was imported into eclipse.
Additional Info: in eclipse's Problems View I see the following error:
"The project cannot be built until build path errors are resolved"
In my case the imported project find the libraries just right(by just right I mean I can see the external path to each of the android libs in this case 2 libs, android.jar and maps.jar). So no shuffling of libs in my case, but might be your problem.
I followed Spock's suggestion of cleaning the project which I had to clean multiple times until it somehow resolve its issues. After, issue was solved I had to specify an AVD for the project to run and soon after was up and running on the emulator. Also, note that my eclipse is set up to Build Automatically.
In my case I'm not missing any class files or anything after the clean as the build is properly generating them.
Regards!
I was getting the same error. My problem was that i had an android device hooked up to debug with. As soon as I unplugged it I was able to export.
The answer I found was checking the source and library build path in the project's properties. Most likely there will be a duplicate as in something being referenced in both the source and library tabs. So delete the extra in the source tab and then clean the project and you should be good to go.
Either:
javax.net.SocketLibrary is in your source code, or
javax.net.SocketLibrary is included in a JAR file in your project
Under certain conditions it gets its knickers in a twist and the best fix I've found is to remove referenced jars, clean, add them back in and then compile again.
I believe the error can be caused by including the same classes twice.
This error will also occur (and you won't be able to get rid of it by cleaning) when using classes that are not part of the Android environment.
To summarise the information in the link bimbim.in provided (well my understanding when I glanced over it)
The Android Davik VM tries to compile the jars but finds some stuff that it can't compile to .dex files
so
Just create a "lib" directory in the root of the project (where the src, bin res directories are) and add them to the build path. Project Properties... Java Build Path... Libraries.. Add JARs..
I could resolve this issue by creating a new project, looks like the some project settings were creating this issue and could not really find the root cause for that. But, dumping the existing source code onto the new project resovled this issue. If anyone has found the root cause for this problem pls do let me know.
I had the same problem and solved it as follows:
- Go to Project/Properties/Java Build Path/Libraries and remove all JARs except Android
- Do a project clean
- Add the JARs again as External JARs (first time I added them internally, so that might be the problem)
After that the error was gone.
I solved the problem by updating available packages in the Android SDK et AVD manager. No need to remove Eclipse.
Whenever the Project is having the ambitious data. This problem is caused. May be android can't able to find which one choose.
From what I understand, this same cryptic error could be caused from a wide variety of reasons. I've got "Conversion to Dalvik format failed with error 1" error too. In my case the problem was that for some reason Project -> Properties -> Java Compiler was not set to "Enable project specific settings" with proper Java 1.5 settings, but was left to defaults instead (1.6 in my case). Debug, build and test on devices/emulators worked fine, but export always failed with the above error message.
If unsure about the proper settings, create the same project on some alternative location and just copy all needed files from the old project into the new one. This fixed the issue for me.
The next problem with the same error message came from using proguard. Updating to the latest version by replacing the one that came with android sdk, fixed that.
Hope this helps
My problem was having a jar file in my src folder. Removing jars from the build path works, but only if you don't need the jar in question. For people who need the jar in question, make sure that your jar file is not in the project folder (maybe just src subtree, but I would keep it separate to test). Put it on your desktop or something and try the "Add external jar.." option. Be sure to remove the jar from the project filesystem before adding another external. Having both is what causes the problem.
I have done it as the instruction of the first answer and it works.(Linux)
I think the problem may caused by SDK or ADT updates.
I do have to clear all the lib in Java Building path and then use android tools to fix the project. After cleaning and rebuild, it works as before.
