Connecting to Parrot Anafi drone from Unity

Question

I'm try to connect my drone to my Unity project (I'm making custom UI interface) After doing some readings, I built a small module in Android Studio and made connection with my unity project (sent and receieved basic messeges). I tried the Anafi example project, seperatly, and it worked. Then I proceeded to include the relevant libraries in my module and that's where the problems started.

Even thought I included in the dependencies

    // GroundSdk dependencies
    implementation ('com.parrot.drone.groundsdk:groundsdk:7.0.1'){transitive(true)}
    runtimeOnly ('com.parrot.drone.groundsdk:arsdkengine:7.0.1'){transitive(true)}

When I try to obtain session with

mGroundSdk = ManagedGroundSdk.obtainSession(UnityPlayer.currentActivity);

My app crashes. I can see the problem in Android Studio's Logcat

After doing some more research I found out the my dependencies weren't included in the AAR module (?)

Is there a way to include the GroundSDK in my AAR? How do I do this manually?

Thanks in advance!

To people from the future facing the same problem, The answer is to check the “custom main gradle” option in Player Settings => Android => Build and add the references there
