Unable to convert classes to dex format - Android issue

PROBLEM WITH BUILDING ANDROID
this happens because 2 things 1.Facebook SDK include files already contained in Assest/plugins/android, and 2. AndroidManifest.xml has to be updated.

so I did this:

1. Open AndroidManifest.xml (Assest/plugins/android/AndroidManifest.xml) with Xcode or Text edit and change line to this:

uses-sdk android:minSdkVersion="15" android:targetSdkVersion="23"

READ the error, it will tell you the values needed.

2. Assest/plugins/android/libs (NOT FacebookSDK/plugins/android/libs ) select All files, and in inspector deselect "android". (some people suggest to delete them, but i just deselect them so when the project builds they won't be included).

3. in finder look for .jar files duplicates and delete the ones that are in plugins/android Not the ones in Facebook

this was my case, maybe your is different, what I did was to look for duplicate files in Facebook SDK and Assest/plugins/android!*/

 

In my case, my project used a .jar that's compiled by jdk 1.8, and I get this error when setting jdk to 1.7 in unity.
I turned to 1.8 and everything's ok.

 

@ShoutTree you should install JDK 8, and then point your Unity installation to use that (Under Preferences -> External Tools)

 

Yes, I did it. Thank you.

 

I has this error too, I had some plugins and google firebase, I just remove plugin folder content then install firebase then install other plugins, the problem solved !

 

I am having the same problem and its with google play and facebook and untiy. I cant believe I am having trouble with these 2 plugins where they dont work together. Over engineered software that doesnt even work.

 

I solved it without removing of any files.
You should do the following: file>Inspector>SelectPlatformForPlugin>Standalone. Apply. Do it for both files under plugins: support-v4-23.4.0 and support-annotations-23.4.0

 

Really wrong advice by @firaskallel . these files are Android related, and should not be included in Standalone builds.

 

Hello

I had the same problem and, as some said, it's was a problem of duplicated files.

For me it was the files:

support-annotations-24.0.0.jar
support-v4-24.0.0.aar

They were present in my "Assets\Plugins\Android" folder and in my "Assets\FacebookSDK\Plugins\Android\libs".
(The one in the Facebook folder was a different version)

I deleted the one in the Facebook folder (when I tried to delete the one in Android, it came back automaticaly).

 

You've made my day!
Thank you very much for sharing!

Before reading your post i removed some bolts... jar files and don't know if I should put them back, since I don't remember where they were. Project compiles with no errors, so I guess those jar files are not necessary.

 

search support

My problem are solved/

 

This fixed it for me as well thanks! They didn't show up in the Unity editor for me so I navigated to the patch in file explorer, and low and behold! Deleted the files. Problem solved.

*EDIT* Actually I found that I still had an issue with GPG services crashing my app when I actually went to use them in the built application. I had to replace the existing aar's in the "Assets\Plugins\Android" folder with the attached versions. I then went to Assets/PlayServicesResolver/AndroidResolver/Settings in the unity editor menu to disable "Install Android Packages." Hope this helps someone with the same issue.

 

I solved it by removing UnityAds.aar. Open your project files go assests-plugins-Android there will be UnityAds.aar just delete this.

 

I had the same issue and it was a duplicated lib, I used many plugin in my project and some of them already included "android-support-v4.jar", just deleting duplicates solve my pb.

 

I agree with @awesome-alex you should search your entire project for files containing the word "support", then delete any files with duplicate file names (leaving just a single copy of the file with that name). This is most often the solution to DEX errors.

 

I solve this problem deleted dublicated file .jar
this problem apear then I updated applovin

 

Solved this problem deleting project/plugins

 

Solved this problem.
This issue is only due to SDK, use some previous version of SDK to resolve your problem

 

Just had the same problem ... Just deleted the old files that are duplicated with older version ... see the screenshot

 

Great ... thanks dear

 

For me I had incompatible sdk/jdk/ndk I had to install ndk r13b, jdk 8 and sdk 21 That helped solve this problem.

 

Just in case anyone still has this issue, I encountered this problem and was able to solve this way:
1. I deleted the downloaded Unity Ads Asset
2. Navigated to Assets/Plugin/Android
3. Deleted anything that started with UnityAds.*
4. Disabled Ads under the Services panel.
5. Commented out all codes referring to Advertisements in my game.
6. Restarted Unity.
7. Tested the game, now without adverts. I expected this to work as normal.
8. Re-hinged the Ads on the services panel.
9. Un-commented the Advertisement code.
10. Commented out the Advertisement,initialize line.
At this point. all worked well.

 

I have this problem even with empty project: I created new project - apk build success. Imported only the facebook-unity-sdk-7.11.0 there - have apk build failed:
CommandInvokationFailure: Failed to re-package resources.
C:\_androidWork\build-tools\27.0.3\aapt.exe package --auto-add-overlay -v -f -m -J "gen" -M "AndroidManifest.xml" -S "res" -I "C:/_androidWork\platforms\android-25\android.jar" -F bin/resources.ap_ --extra-packages ...

Any help please...

 

just got this one also,
looks like it probably started happening after importing EasyMovieTexture and UMP-plugins to same project.
(was just testing, so not sure how to fix for those)

If you have used Admob then look for "support-v4" file under your Plugins> android folder. Probably it would have been duplicated and you need to delete one of them. It doesn't necessarily have to be in the same folder.

 

I want to add one more cause of this.

If you are making your own Android plugin with Android Studio and you reference `unityclasses.jar`, if that slips into your .aar file it will conflict with the one Unity is going to add `classes.jar`. The error will be like this.



To fix, in your build.gradle file instead of adding dependencies as `implementation fileTree` you use `compileOnly` instead. It can then use your project `unityclasses.jar` just for compiling but not adding it to your .aar, then your .aar will use the real one Unity is going to add at runtime.

Code (CSharp):

1. dependencies {
2.     // Avoid redundant Unity Player in final application APK
3.     compileOnly files('./libs/unityclasses.jar')
4. }

To debug what's in your .aar you can change the extension to .zip and you can see everything inside.

 

I had the same error and turns out it was because I had to jar files similar. One was in the path of facebook sdk android plugin and the other was the default one that exists in Plugins/Android. I deleted the one isnide facebook path and it worked. Dont rename just delete it entirely

 

would you kindly tell me something more ! i have same plugins which youhave ...

 

will you knidly tell me something about this error

 

My latest DEX issue was related to Unity Ads. I resolved it by going to Window -> Services -> Ads -> Advanced and then unchecking the box for "Enable built-in ads extension".
