This video is from my CS 282: Systems Programming for Android class that was presented on September 4th, 2013. It discusses how the Gang-of-Four Template Method pattern is used in Android and walks through an example Android app that uses Activities to display an address location on a map. The audio is not as crisp as usual due to technical problems, but it should be good enough to follow along. Please see www.dre.vanderbilt.edu/~schmidt/cs282/ for all the material in CS 282.
CS 282 will provide students with an intensive focus on conceptual and practical aspects of designing, implementing, and debugging concurrent and networked software systems using patterns and frameworks related to Java and Android middleware. Key topics covered in this course include: developing, documenting, and testing applications using object-oriented frameworks associated with Java and Android middleware; Reuse of patterns and software architectures; Developing concurrent and networked software using Java and Android.
Design and implementation based on patterns and frameworks are central themes to enable the construction of reusable, extensible, efficient, and maintainable networked system software. In addition, abstraction based on patterns and OO techniques (such as separation of interface from implementation) will be the central concepts and principles throughout the course. These concepts and principles will enable you to construct reusable, extensible, efficient, and maintainable networked system software.
Patterns will be taught so that you will have good role models for structuring their own designs, as well as to clearly articulate the tradeoffs of alternative methods for designing systems. OO techniques will be taught so that you will learn by example how to build highly decentralized networked system software architectures that decouple inter-dependencies between components. You are expected to be familiar with Java and basic Android.
