Symptoms
- My Android build is failing
- I am using both Unity IAP and AdMob.
Cause
Both Unity IAP and AdMob include the in-app-billing-service-aidl.jar, resulting in two copies of the file. The Android build fails since it is unable to resolve the duplication.
Resolution
Delete one of the copies of the file "in-app-billing-service-aidl.jar" from your project and the build should work.
