I am using in-app billing 3 in my apps. I want to update to in-app billing 5. How do I do that? I have searched without finding any info. Is the only thing I should do to update the IInAppBillingService.aidl file? No other files need to be updated?
The newer versions just seem to add extra functionalty to the existing API so yes, I believe you would just need to change the AIDL file to use the new features.
