I am integrating dropbox API with my android project,for that I downloaded android SDK from this link and also another example project from this link.While integrating both example codes in my project shows error at run time.I searched many solution in internet but unfortunately it wouldn't make my code error free.
This is my console screen
[2014-05-10 09:37:43 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/dropbox/client2/android/AuthActivity;
[2014-05-10 09:37:43 - ExampleDropboxApp] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/dropbox/client2/android/AuthActivity;
So any one please do a needful to me.
This is because the inside two Dropbox API jar files both have the class
com/dropbox/client2/android/AuthActivity.
The simple way is to remove one of them from one of jar file. You can use 7z or programs to remove them.
Here's a screen shot of the files you might need to remove in that jar file
I was facing the same problem few days back. I am mentioning below what Worked for me.
Right Click on your Project Name
Click on Build Path
Goto Configure Build Path
Goto tab Order and Export in Java Build Path
Uncheck your .jar Library.
Do let me know if this work for you :)
The ultimate solution should be to:
Open both jar files; dropbox-sync-sdk-android.jar and
dropbox-android-sdk-1.6.1.jar
Delete the client2 folder in the former sdk and replace it with
client2 from the latter
Then download a copy of json_simple-1.1.jar.
Copy json_simple-1.1.jar and dropbox-sync-sdk-android.jar into your
libs folder and include these two in your project properties; this
will help to avoid future errors
NB: You don't need to include dropbox-android-sdk-1.6.1.jar anywhere.

I can see the same question has been asked many times, but from all the answers available I couldn't find any solution for my problem.
My project is using 2 library projects & I also have included following jar files in libs.
- android-support-v4.jar
- aws-android-sdk-core-2.1.10.jar
- aws-android-sdk-s3-2.1.10.jar
- crashlytics.jar
- gson-2.3.1.jar
- library-1.0.15.jar (For Volley)
- picasso-2.2.0.jar
While development, my app was running fine. But the moment I tried to Export, for creating signed APK file I got an error message.
"Conversion to Dalvik format failed with error 1"
In console, I checked the messages,
"Jar mismatch! Fix your dependencies
Found 3 versions of android-support-v4.jar in the dependency list, but not all the versions are identical."
In the message itself I checked that one of the android-support-v4.jar (from one of the library projects) files is different, so I replaced it with the other jar file. Now all the jar files are identical.
But now when I try to run the project I am getting one another error message
"Your project contains error(s), please fix them before running your application."
Now on checking console I see following messages.
[2015-07-15 11:23:13 - Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/annotation/AnimRes;
[2015-07-15 11:23:13 - MyApp] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/annotation/AnimRes;
From some answers, I found that this issue is because of to multiple occurrences of the same jar file getting added in the project.
All the included jar files are 3rd party & necessary for the project.
I have tried some of the ways suggested in other answer, but I am not able to solve this issue.
Please help me to solve it.
Finally managed to solve it.The issue was because of to multiple occurrences of the same set of classes or jar files. In my libs folder, there are 2 jar files
-gson-2.3.1.jar
-aws-android-sdk-core-2.1.10.jar
& both of these contain Gson class. In aws it is in package com.amazonaws.com.google.gson.Gson & in gson lib it is in com.google.gson.Gson.
So because of this I was getting the error message Multiple dex files define Landroid/support/annotation/AnimRes;.
Now I have removed the -gson-2.3.1.jar file from libs because it's feature, I can use from the -aws-android-sdk-core-2.1.10.jar lib.
After cleaning the project, I was able to create signed APK file.
In my case, I've removed Android Private Libraries from Project properties/Java Build Path. The result looks like at the pic
Solutions to errors conversion of dalvik failure format and error sun / misc / basecoder64 in Eclipse.
Instructions to solve the problem are:
Install Windows XP sp2 with Java 6 or Ubuntu.
Download adt version 23.0.2 with SDK 19.
Decompress the adt and install it on your computer.
Open Eclipse as administrator and import the android file.
In the file project.properties add target = android-19.
Export your project and this error will no more appear.
I have been noticing one major problem in android that
When I use/import couple of jars in my android app for development purpose so I get below exception:
[2011-10-23 16:23:29 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;
[2011-10-23 16:23:29 - myProj] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;
I have been noticing this problem when I import/use different jars for app development. I got to
Project->Properties->Java Build Path->Order & Export->
Then assign jars priorities.
And then I go for running project so I get this exception. And every time I struggle to solve this issue. I know this issue raise due to common contents of jar but ant to know reliable way to handle it.
That's why I want to know how to deal with this?
I faced this issue multiple dex files means your application have different source for same class.
To fix it i used use same jar file(android-support-v4.jar) for project and libraries also. (copied same jar file in project and library).
This issue arises not only with the android-support-v4.jar, it can arises with other libraries too. This generally comes when you import some library in your project.
To resolve this just figure out which jar is showing the multiple dex issue and make sure to have the same jar in your project and as well as in the libraries which you have imported. Doing this your problem will be resolved.
Check out all jar files added in lib folder of your project and all dependent library and remove jar if it is already added in another project or lib. This error will be only because of more than one source for same class.
I am importing Play Haven sdk in a test project, its importing successfully but when i am trying to run my project its giving same error again and again.
13:24:12 - Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;
[2014-03-28 13:24:12 - PrintOutApp] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;
Play Have SDK link : http://help.analytics.upsight.com/api-sdk-reference/downloads/
There are 2 options:
remove android-support-v4.jar from your project [not from Haven SDK project
remove android-support-v4.jar from you project and copy it from haven sdk project
Check your project for multiple of the same file.
Use a simple file search to look for *.jar in your project files.
Some files may be named differently (I wish SDK makers would not do this) and contain the exact same libraries.
I ran into this issue myself, and it was exactly this file android-support-v4.jar. However, one of the SDK's I used renamed that file to something else. So it was a hard find.
Hi I am developing small android application using eclipse tool. I am including two jar files into my project support version-4 and another is my library jar file. When I ran my application it run successfully but i tried to use it gives me some errors regarding no class def found error. So I do to project properties and there in java build path order and export I checked two jar files. After that i clean build my project and try to run my project. SO while running my project it gives me error. Run time error is as follow:
[2013-07-08 12:19:16 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/haarman/listviewanimations/ArrayAdapter;
[2013-07-08 12:19:16 - ListViewAnimationExample] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/haarman/listviewanimations/ArrayAdapter;
I check around this problem and according solution I delete my bin and gen folder and also tried again run but it gives me same error. How to solve this problem. Is it related to my project set up or its related to eclipse? Need Help.
Thank you.
This is a build path issue. Check that your bin folder is not part of your build path. Typically you get this when you have two of the same jars, but with different versions. Are you using external libraries like ActionBarSherlock? If the android-support-v4 jar you include is a different version than the one ActionBarSherlock uses you will get this error.

Also check Make sure that the value of android:targetSdkVersion in AndroidManifest.xml matches target=android- in project.properties.
I am unable to build my application
I am running the latest build tools downloaded today, this started happening after the update.
-dex:
[dex] Converting compiled files and external libraries into

I have tried cleaning and rebuilding, I've also tried in Eclipse but it gives the same error.
Anyone got any ideas? I'm at a brick wall here now.
I spent hours cleaning, creating new projects, uninstalling-reinstalling sdk... nothing worked. I didnt have any library project either ( i just had some jar files under lib). Howerver, In the end I fixed it and my steps were:
Search and clean all .apk files ( I had some in .svn folder...grr.. some developer had added some build related folders under svn)
delete bin and gen.
From eclipse project properties remove reference to library jars, press ok. Then again add them back. I had some java compiled jar library. I don't know why I had to remove and add it back, but that surely was needed.
Something happened yesterday to my system (and another here at work) where the SDK wanted to push the platform tools update but then I was unable to use it at all, etc.
I ended up moving my SDK out of the way and reinstalling it, then everything worked as it always had. I did not have your dex specific issue, but I suspect the update push yesterday broke a good many things. Good luck.
You can:
Delete folders <.settings>, <bin>, <gen>, and files <.classpath>, <.project> and <project.properties>.
Delete your project in Eclipse (right button, <Delete>) without deleting the source files.
Create a new Android project and select <Create project from existing sources> from your previous sources.
Import external libs, if needed in the build path.
It should solve this annoying problem.
Be very careful about all source files you attach to/have in your project.
I found this problem in two situations:
When I have two different android support library jars
When I accidently put in the past some Facebook src not as a library, but directly into my src directory
So all answers which says that you shouldn't put your bin/ directory into class path are also correct, but in situation where you have error like:
[2013-08-02 20:22:03 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/facebook/android/AsyncFacebookRunner$1;
[2013-08-02 20:22:03 - Activity] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/facebook/android/AsyncFacebookRunner$1;
you should look for same jars in project/libraries (this should be founded by Android Eclipse environment in most cases) or look into all sources attached to project to find multiple occurance of (as in example code above) of class com.facebook.android.AsyncFacebookRunner
I think the directory in bin change from
com/XXX/XXX
to
classes/com/XXX.
You can clean your project and solve it.
I was seeing this same problem. If you're using Android Studio, you need to make sure you don't have the 'bin' or 'gen' folders included in any of your projects when you're compiling.
After removing this I was able to compile successfully
If you're having issues because of Multiple DEX files
Remove the entire target folder and build the project again. This won't affect your project cause everything in the target folder is built again.
Change implementation fileTree(include: ['.jar'], dir: 'libs') to
provided fileTree(include: ['.jar'], dir: 'libs') in your app gradle.build> dependencies.
Make sure it has changed in your Module Settings> Dependencies {include=[*jar] dir=libs} too. It must have a scope of Provided next to it and not Implementation.
