期末作品报告课程名称： Android应用程序开发学号：姓名：班别：1引言在这个快节奏的时代，人们的空余时间越来越零碎，而且人们对智能手机的依赖越来越重，所以，一个拥有丰富功能且能随时进行电子书阅读的在线小说阅读器的出现，则是我们刻不容缓的事情。
此软件是在Android平台上进行设计开发，此软件的开发是通过了客户需求分析阶段以及技术可行性分析阶段，然后进行总体设计阶段和详细设计编码等阶段。
此软件不仅具有基本的电子书阅读功能，而且还拥有丰富的实用功能设计。
经过不断的测试与完善，电子书阅读器功能稳定，并且在真机上对其进行了测试与验证，基本上达到了用户的需求标准。
1、功能分析1.1项目来源此次开发的项目是在线小说阅读器，属于自选项目。
随着社会的发展，人们的生活节奏也越来越快空闲时间也越来越零碎，人们没有了大段的时间来进行书籍的阅读，所以一款能利用零碎时间进行随时阅读的软件成为了我们的需求。
而一款能在人们随身携带的手机上运行的阅读软件成为了大家的选择。
以前我们看看杂志，小说都要去图书馆借阅，而且时间有限，很不方便；而在电脑上看杂志，看小说，文档也是很不方便的。
以此看来，一个好的手机阅读器软件的开发是相当有必要的。
1.2开发目标在线小说阅读器的开发目标就是让用户可以把零碎的空余时间有效的利用到书籍的阅读上，而且用户在没有网路的情况下也可以正常的进行书籍的阅读,让用户摆脱书籍的笨重携带不方便等确定，给予阅读者更大的便利性更好的舒适性。
此软件是在Android平台上进行设计开发，它的界面丰富简洁但是却不简单，它包含了书架界面、2文件查看界面、软件设置界面、书籍阅读界面等界面，它的功能全面。
其优越性表现在：自动扫描手机里的所有书籍、手动从文件夹中选择添加书籍、自动为书籍生成章节目录、添加查看书签、全文关键词搜索、阅读主题选择、阅读字体大小设置等功能。
此外，给用户更清晰方便的界面，也是本软件的出发点之一。
2、功能设计2.1系统功能设计根据需要，在线图书阅读器主要实现即时的在线阅读，主要包含以下功能：(1)在线即时搜索图书：可以按照书名、作者进行搜索所要阅读的书籍。

摘要基于Android平台的电子书管理及阅读系统，是采用JA V A语言开发的一个小型应用系统。
在科技日益发展的今天，社会竞争越来越激烈，3G时代已经慢慢融入了我们的日常生活。
手机已经成为人们日常生活中不可缺少的一部分，尤其是在电子产品日新月异的今天，我们在平时随处可见的电子产品中，手机无疑是一个最大的用户集，而各大厂商智能手机则依旧是电子商场的一个耀眼明星。
其中代表作有微软的WP7系统，苹果的IOS系统，但是其中Google的Android系统以其开放的源代码和方便简洁的操作成为手机领域的领头羊。
所以我选择了这个题目作为毕业设计的题目，并希望再进一步完善系统后将系统发布到Google android market上供用户下载使用。
据了解，越来越多的年轻人喜欢阅读小说，本系统则根据用户需求及平台的特性而设计的，在Google Android SDK2.1环境下，运用Eclipse，PhotoShop等相关工具进行开发。
同时解决了大型书籍载入、动态分页等众多技术难题。
该系统在Android手机上运行，由于手机性能及内存的瓶颈，在设计方面，本系统进行了相应的优化处理，以减少不必要的内存损耗，尽可能的使其在手机上能够流畅运行，增强友好度，方便用户使用。
