Android 6 and the design support library continue to push mobile design forward.
In Android User Interface Design, Second Edition, leading Android developer and user experience (UX) advocate Ian G. Clifton shows how to combine exceptional usability and outstanding visual appeal. Clifton helps you build apps that new users can succeed with instantly: apps that leverage users’ previous experience previous experience, reflect platform conventions, and never test their patience.
You won’t need any design experience: Clifton walks you through the entire process, from wireframes and flowcharts to finished apps with polished animations and advanced compositing. You’ll find hands-on case studies and extensive downloadable sample code, including complete finished apps.
