摘要
随着我国科技水平的提高和移动通讯的飞速发展与普及，人们通过移动网络 可做的事情越来越多，人们之间的沟通不在局限于面对面的对话，人们通过手机
可以很方便的上网并通过手机上的 APP 进行聊天这样既节省话费开支又方 便快捷。并且在信息时代的今天,相对与手机号频繁更改，人们的网络软件账号 相对
固定。因此使用移动聊天程序进行沟通交流更有助于人们之间保持长久固定 的联系。
本设计通过配置 Android SDK、Eclipse、ADT 插件、java-jdk 来搭建 Android 的运行环境和 Android 程序开发过程中可以使用其自带的内嵌的 SQLite 数据库 来实现程序的结构化数据存储，能够实现用户的一对一的聊天功能，在 Android 手机平台上实现聊天满足文字、图片、语音的实时收发。聊天程序包括手机客户 端和服务端两部分，服务端程序利用数据库保存用户的信息，客户端实现各功能 的展现界面，并实现与服务端以及聊天对象客户端之间的通信，本程序利用 StartUML 工具，进行统一建模并进行系统用例模型的设计，进而完成移动聊天 程序。

summary
With the improvement of China's science and technology level and the rapid development and popularization of mobile communication, people can do more and more things through the mobile network. The communication between people is not limited to face-to-face dialogue, and people pass through their mobile phones
It is convenient to surf the Internet and chat through the APP on your phone to save phone bills and fast.And in today's information age, relative to the mobile phone number frequently changed, people's network software account relative
fixed.So using mobile chat programs can help people maintain a long and fixed contact.
This design configure Android SDK, Eclipse, ADT plug-in and java-jdk to build the Android operation environment and Android SQLite database in the development process to realize the structured data storage of the program, which can realize the one-to-one chat function of users, and realize the real-time transmission and reception of text, pictures and voice on the Android mobile phone platform.The chat program includes the mobile phone client and the service terminal. The service side program uses the database to save the user information, the client realizes the display interface of various functions, and realizes the communication with the service side and the chat object client. This program uses the StartUML tool to conduct unified modeling and design the system use case model, and then completes the mobile chat program.
