AdColony SDK Integration - "Your hardware does not support this application"

Hi,

I'm trying to implement AdColony SDK 3.3.0. Since I'm using Grandle (new) as build system, I added the following code within the mainTemplate.grandle file as suggested by their guide

android {

  sourceSets {

   main {

     jniLibs.srcDirs = ['libs']

   }

  }

}

I can successfully build the apk but after adding that line of code I get this error when trying to run the app:
"Failure to initialize! Your hardware does not support this application, sorry!"

I'm experiencing the issue on both my devices:
- OnePlus 5T with Android 8.0.0
- Nexus 9 with Androdi 7.1.1

I'm using Unity 2017.2.0f3 and within player setting, Minimum API level is set to 16 and Target API level to 26.

Does anyone know what could be the problem?

Thank you.
