As the world's most popular mobile operating system, Android has grown phenomenally in just a few short years. Creating an app that stands out in a world with hundreds of thousands of other apps is becoming increasingly more challenging, so designing your user interface to be both usable and visually pleasing is extremely important. Written by expert Android application developer Ian G. Clifton, Android User Interface Design will help you accomplish both of these goals and more. Whether you have a dozen apps already published or you have just completed the Hello World tutorial, this book will guide you through the complete process of brainstorming, wireframing, designing, and building Android apps. You will make use of the latest design patterns while taking advantage of the newest features of Android including Jelly Bean's rich notification system; at the same time, you will maintain compatibility with older versions of Android by use of the support library and reflection techniques. Learn to create goal-based mobile user experiences, understand visual design patterns and best practices for implementation, create custom views with advanced graphical techniques and specialized touch handling, and turn your ideas and sketches into beautifully designed apps. This book covers: · An overview of Android UI and design philosophies · A detailed guide and reference to Android's Views, ViewGroups, and resources · Real-world application design including wireframes, flowcharts, and comps · Implementation of design using standard components (including the action bar, ViewPager, Fragments, and other newer Android UI design patterns) and fully custom views · Advanced graphical techniques including Porter-Duff compositing and more
