This example MIDlet shows you how to use the Game API to create a Java game called Battle Tank for Series 40 and Symbian devices. The example also shows you how to use the In-App Purchase API to integrate a built-in-DRM-based Nokia Store purchasing feature into a Series 40 MIDlet. While the gaming features in this example are compliant with both Series 40 and Symbian, the in-app purchase feature is only available on Series 40 devices and therefore the MIDlet as a whole can only be run on Series 40 devices that support the In-App Purchase API. For an earlier version of the MIDlet that does not include the in-app purchase feature, see the Nokia Developer Project.
