Program type already present error when gradle build

Hi,

When i try to create an android build with gradle. I get this error. I already try to delete and reinstall all sdk's(currently only 3 services i am using, facebook sdk, google ads and unity iap) But only error information changed(now it says "Program type already present: com.facebook.unity.Constants", before it said something like " "Program type already present: android.support...") I already google that problem. But most of the solutions with android studio etc and others doesnt work. I dont have any android studio experience, so is there any practical solution for that issue?

 

It would be great to share screenshot of Assets/Plugins/Android folder to look into the issue.

 

this is my android folder, i can't see any duplication but may be i am missing something

 

Can you please share the error completely?
Also all the libs are listed in the above screenshot or something pending?

all libs are listed at this screenshot, in the plugin/android folder.

 

do you have any suggestion about the issue? all of the libs are in ss.

 

finally i found a solution. If anyone will facing this problem, solution is aar files. check plugins/android for duplicated aar files. and check other potential sdk roots like facebook/plugin/android. There will be other aar files.

 

Hello I have this problem too now. There are multiple aar files all over the place with different names. Is deleting all of them the solution? which should i delete?

 

First search for all *.aar and *.jar files in the project and paste here.

 

This is actually an Android related problem.


When two libraries (e.g AAR files) contain one or more classes with same packageName (e.g

com.example.library.Class1

), the Gradle can not decide which one to use and include in the main source path, so it'll throw an exception.

To solve this you must know which one of these libraries are having duplicate classes (In this case the class is

com.facebook.unity.Constants

).

Following bullets may be helpful:

• If you have used

  mainTemplate.gradle

  and the

  JarResolver

  , this might be the reason to the problem. They may add one library in their own way and the AAR file gets added twice.
• If you have added only AAR files to the project, you can search their `classes.jar` and look for the duplicate class (Again, in this case `com.facebook.unity.Constants`), and find the blamed AAR files and deal with them.

TL; DR

The AAR files are having some classes that are identical. You must find those AAR files and deal with them (Delete one, ...).

 

HI. Where should I look for AAR files?. For me error is this:
D8: Program type already present: com.bazaar.BazaarIABPlugin$2
I Could build an APK before importing a plugin but now I'm getting this error and is referring to the one of the plugin library.
Please tell me if you need more details
