This chapter is about design guidelines for writing imaginative and useful Android applications. Several recipes describe specific aspects of successful design. This section will list some others.
One purpose of this chapter is to explain the benefits of developing native Java Android applications over other methods of delivering rich content on mobile devices.
There are a number of key requirements for successfully delivering any mobile handset application, regardless of the platform onto which it will be deployed:

An application should be stable, scalable, usable, and responsive.
It should use the platform’s capabilities tastefully when it makes the user’s experience more compelling.
