Hi, I am using Samsung Galaxy S2 getting the following error everytime while running my inapppurchase app. Even the same build is working in my friends device (same Samsung Galaxy S2 ). Please see the attached screen shot sdkversionerror.png. Both are having the same version of the app.(220.127.116.11) It asked me to download the older version app the tester app. "[b]The SDK Tester Version(18.104.22.168) You are using is not supported. please download the latest supported SDK Tester Version(22.214.171.124)[/b]". I am having the latest version only. please help me to solve this issue.
