congratulations for your application and thanks for suggest about Proguard
I would like to ask you a question as you use InApp Billing
I would use Proguard in my app, I use BillingLibary from robotmedia and if I try to enable proguard in my project.properties I receive some error from robotmedia library (it seems)
I use default setting:
I tried to enable Proguard also in BillingLibrary project but the error happens again
So I ask you, Do you use BillingLibrary by RobotMedia in your app?
How did you configure Proguard?
