Build problem after integrating Firebase SDK

First post, really hope someone can help me because this project is for college and it's really important.. Ok, so I'm tring to introduce firebase to my project and if I import any of the packages from the SDK my project loses the will to build. I'm on Unity 2017.3.3.f1

Here's the error:

com.android.build.api.transform.TransformException:com.android.ide.common.process.ProcessException:java.util.concurrent.ExecutionException:com.android.dex.DexException: Multiple dex files define Landroid/support/compat/BuildConfig;

also:

CommandInvokationFailure: Gradle build failed.

stderr[

This may help https://firebase.google.com/docs/unity/setup#known_issues

 

Sorry for the emoji's

And thanks for replying so fast! I had skipped that part as I knew I was on .NET 3.5

I followed those steps but it seems I'm missing the referanced dotNet45/Unity.Compat.dll, must try and track that down

 

Hi, I also faced this issue. I solved like that;
1- download and unzip ndk from this link https://developer.android.com/ndk/downloads/index.html
2- copy and paste the folder into your Android sdk folder (in your scenario sdk path is "C:\Users\niall\AppData\Local\Android\sdk\"). Copied folder name should be "ndk-bundle".

that's all.

 

I tried that and the build is still failing. Here's the error:

I eventually got it working with the help of support from Mapbox, it was a plugin conflict

 

Would you be able to describe the fix, or link to it? I'm having the same problem and I'm using Mapbox
