This paper introduces how to extend Google android platform as a game development tool to learn software architecture based on the double stimulation method. It starts with the motivation to choose the android platform since most of students in software architecture course from NTNU (Norwegian University of Science and Technology) have experiences of using java and eclipse platform before they starts this course. And then it describes the design and construct of extended android platform, called ??Sheep?? framework. Further, it presents the application of the Sheep framework as second stimulus means integrated in the game exercises in the software architecture course. Finally, the paper discusses the contribution from the aspects of technology, game ideas and pedagogy.
