From the abstract: Mobile Apps are the new hotness. However, when it comes to building mobile apps, the new hotness can learn from some of the old skool design patterns made popular by the book Design Patterns by the Gang of Four. Many of the original design patterns introduced in this book are extremely useful in today’s network centric world. Classic Design Patterns can quickly solve problems using tried and proven techniques. However, technologies and other demands on our applications have changed, and new design patterns will emerge, many building on the old. Issues such as multi-core development, application security, peer to peer and app to app communications have introduced new problems for mobile application development, and we can gain insight for common, durable and robust solutions by looking for patterns.
