安卓聊天室App的设计与实现

摘要

07年Google发布Android后，方便快捷的用户体验使得移动即时通讯成为即时通讯市场的新宠。作为互联网时代的新兴产业，即时通讯在整个互联网市场中占据着越来越重要的地位。

本系统是基于Android平台开发的一款手机聊天客户端应用程序。系统基于环信IM服务器，实现了注册登录，会话列表的获取，好友列表的获取，文本信息的即时通讯等功能。本系统主要使用轻量型嵌入式数据库SQLite来存储数据，运用x-utils框架实现对数据库的操作。

本文在分析了当前环境下聊天App的发展前景后，进行了系统的设计和实现，并对系统进行了完整的测试。系统具有界面友好，操作简单，方便实用的特点。
