Hi, I had a similar problem and came up with a solution that should work for you. After exporting your unity project you need to manually import into Android studio each of the .aar files that is present in your exported library, (unityLibrary/libs). To do this in AS, go to File - New - Import .JAR/.AAR Package, and select the .aar file. Do this for all the .aar files. Then in your build.gradle (Module:app) file add each .aar to the dependencies section. The same way that you added the "implementation project(':unityLibrary')" before. For me one of them was: "implementation project(':arcore_client')" You don't need to implement files trees for these one. Then in the build.gradle(Module: unityLibrary), as you have above, you need to delete each of the implementations that are automatically added. Leave the top file tree one. That should work for you!
