After updating all of the libraries in my LibGDX project I’m getting an error that says 

> 
> “Cause duplicate entry `META-INFMANIFEST.MF`” 
> 
> 
> 

when adding in the Appodeal SDK. When I click on the source of the error “`:android:javaPreCompileDebug`” I get an error message that is insanely long, but I included part of it below.

I have migrated my project to AndroidX, all the libraries are up to date (unless I missed something) and I have done "Build > Clean Project" in Android Studio. I have had Appodeal working before in another project using an older version of LibGDX but I just created a new LibGDX project using the latest version and then went through making sure all of the libraries I’m using are up to date. Appodeal is the last thing I have to add to this project. The problem line is 

```
implementation 'com.appodeal.ads:nodex:2.5.10'

```

in the project-level `build.gradle` file, if I comment out that line then my app will load. Thanks.

**Part of Error message:**
