Steps to Reproduce

1. Create new unity 2019.4.26 project
2. Set project build target to Android.
3. Import Facebook SDK 11.0.0
4. Import the latest Firebase Analytics SDK 8.1.0 into the project.
5. Import External Dependency Manager
6. Enable mainTemplate.gradle (Player settings -> publishing settings -> check custom gradle template)
7. Click Assets -> External Dependency Manager -> Resolve
8. Enable Jetifier when prompted (or Assets -> External Dependency Manager -> Settings -> Enable Jetifier)
9. Build the project

Code Samples & Details

If you comment out the Firebase implementations in mainTemplate.gradle, the project compiles. If you comment out the Facebook implementations in mainTemplate.gradle, the project compiles.

However, having both UNCOMMENTED (enabled), the above exception is observed.

I got the same issue when including installreferrer jar from other library

[DimaDDM]

Same issue

[Laur-Ivan]

Any fix?

[jkotzian]

Getting the same issue on Unity 2020.3.16f1

Anyone have a fix? I updated Facebook SDK and Firebase, and I still get the error :/
