TAILIEUCHUNG - Lập trình Androi part 02

Sau khi bạn đã tải về và cài đặt mới nhất của Android Software Development Kit (SDK), và có lẽ là Công cụ phát triển Android (ADT) plugin cho Eclipse (cả hai đều có sẵn từ các trang web Android Developers), bạn đã sẵn sàng để bắt đầu. Chương này bao gồm những gì được tham gia vào việc xây dựng một ứng dụng Android. | Chapter Projects and Targets After you have downloaded and installed the latest Android Software Development Kit SDK and perhaps the Android Developer Tools ADT plugin for Eclipse both available from the Android Developers web site you re ready to get started.

To test your application with the emulator you will need to create an Android Virtual Device or AVD. Most likely you will create several of these as each AVD emulates an Android device with a particular set of hardware. You might have AVDs for different screen sizes Android versions and so on. When creating projects and creating AVDs you will need to indicate to Android the API level with which you are working.
