I followed this guide to try and fix this error...
"Error:Execution failed for task ':app:compileDebugAidl'. aidl is missing"
I put "IInAppBillingService.aidl" in "app/src/main/aidl/com.android.vending.billing" and when I rebuild the project, the error is still there. I've restarted Android Studio multiple times... it just won't fix, I've followed the guide to the letter, it's worked for everyone else...
Could anyone help please?
