Redeemable coupons for your android application with App Engine backend
The backend is powered by App Engine. Just create a new project, enter your application id and upload it.
To generate coupons open your App Engine project in a browser. The url looks like this
http://%your-project-id%.appspot.com/coupons?app=%coupon_name%
To use the library, add it as a library project to your Android application. You can either use the available CouponFragment (or the native wrapper fragment) or write the UI yourself and directly use the CouponManager class.
