Introduction
A mobile user interface is based (besides graphics rendering) on multi-touch input. This
chapter shows you how to handle the touch events on the Android OS, and how to debug them
on Windows. A dedicated recipe about the emulation of multi-touch capabilities on Windows
using multiple mice is also included. The rest of the chapter is devoted to high-quality text
rendering and supporting multiple languages.
