Getting Duplicate class com.unity3d.player.UnityPlayer$c found in modules error

I have the following requirement

• integrate android native app in unity app

• First, launch native screen from unity app then launch unity screen from native app

• have a two way bridge between unity and native app

• Export the unity project as a unity package

To do this, i have done the following things

1. created a native project

2. created a unity project

3. exported the unity as library

4. integrate the unity library in android app

5. changed the application module to library

6. built an AAR file of android project

7. added the AAR file in unity at this path - /Assets/Plugins/Android/android.AAR

When i am building the project, it is throwing Duplicate class error Please help me where i am going wrong with this.
