兰州GDG小组活动总结 The Summary of Team-Event of Lanzhou GDG
大家好，兰州GDG的第一次小组活动已经结束了。虽然第一次的活动准备的有些仓促，但活动的目的达到了，并且组织了一个开发小组，将根据已经开发好的一个BBS客户端的Demo，围绕BBS客户端功能的完善和界面的美化开展工作。 Hi there! The first team-event of Lanzhou GDG has come to the end. Although it is a little rush into the preparation, the goals are attained. A team is set up to improve the function and UI of the LZU BBS client, which is now a demo.
本次活动以讨论Android校园应用开发为主题。在学校里，存在这样的问题：不同的部门提供了不同的服务，并且都是以网站的形式。用手机查询即费流量速度又慢，而且还经常遇到“请使用IE浏览器访问”的提示。所以我们想用客户端来整合这些服务。 The purpose of this event focuses on the theme of The Android Development of Campus Application. In the campus, different departments provide different services, which are always used through different websites. Accessing the website with smart phones not only wastes mobile data, but also response slowly. What's worse, the warning “Please use IE browser” drives you creazy sometimes.
一、活动信息 I. Event Information
时间：2013年4月11日 19:00 – 00:30 Date: 2013-04-11 19:00 – 00:30
地点：兰州市城关区甘南路684号凤栖梧 Address: Feng Xi Wu, Gannan Road No. 684, Chengguan District, Lanzhou City
在线报名人数：14人 Registered online: 14
实际参会人数：26人 Participants: 26
二、活动内容 II. Activities
19:00 ~ 20:00 人员陆续到场，并作一个自我介绍 19:00 ~ 20:00 Participants arrive and introduce themselves.
播放视频：Android使用SAX的方式解析XML文件
Play a video: Android Parses XML File Using SAX Method
视频教程模拟了这样一个使用环境：服务网站提供了基于XML的API接口，用于输出相应的数据。Android应用程序通过HTTP连接服务器，利用API获取XML文件内容，然后使用SAX的方式解析XML文件，并提取XML文件中的数据。
The video simulates a use case, thus the website provides APIs based on XML to output data. Android application connects the server through HTTP, and use the API to get the XML content. Then app parses the XML using SAX method, and gets data.
通过这个视频，我们可以学习基于网站API开发的最基本的过程，为后续的校园应用开发提供一个实例。
This video shows us the basic development procedure of using website APIs on Android. It provides a simple example for us to develop XML and network based campus applications.
20:00~22:00 演讲内容：报告首先演示了兰州大学西北望BBS客户端Demo。接着介绍nForum（BBS程序）所使用的API，及通过BBS客户端的登录过程来介绍API的使用方式。接着介绍了BBS客户端代码结构以及编程规范。最后提出了BBS客户端在开发过程中遇到的问题，以及开发现状。 The LZU BBS client demo is shown at first. Sheng introduces the APIs of nForum (BBS server), and illustrate the loginning to BBS to introduce the use of APIs. Then the code architecture and programming specification are introduced. Finally, the development status of the client is introduced and the problems found during developing the client are raised.
22:00~00:30 学校里，同学通常会用到哪些服务？
In the campus, which services are used usually by students?
查询课表、成绩，图书馆服务，社交服务，活动通知服务等。
Querying school timetable, quering exam results, library services, social contact, information notification etc.
BBS客户端应该采用XML还是JSON格式的接口？
Which format of data should be adopted by the client? XML or JSON?
JSON比XML文件更节约流量。
The file size of JSON is smaller than XML.
BBS客户端应该采用类似于SAX的流处理方式还是采用类似于DOM的方式来解析接口文件？
Which method should the client adopted? SAX or DOM?
考虑到BBS中文章的大小不会过于大，因此，采用DOM的方式解析更加灵活简介。（Demo应用使用SAX的方式解析）
Considering the size of an article in BBS would not too large, so, the DOM method may performance easier and more flexible.
BBS客户端开发团队组织
The Team of Developing The Client
开发成员：jimogsh负责组织，讨论开发计划；longth、huangzy0138负责BBS网站API的开发；shyodx、kjeldahl、wut负责Android代码的开发；Mendy负责界面设计与美工。
Team members: jimogsh is in charge of organizing discussion. longth and huangzy0138 are in charge of developing BBS APIs. shyodx, kjeldahl and wut are in charge of developing the client. Mendy is in charge of designing the UI.
如果有同学对这个开发感兴趣，欢迎联系我们 :-)
If you are intrested in our proposal, you are welcome to contact us :-)
BBS客户端下一步开发计划
The Plan of Developing The Client
1. 确定BBS客户端界面及显示方式
1. Determin the UI and interactive mode of the client
2. 根据Demo，优化整体框架
2. Improve the framework based on the demo
3. 逐步丰富功能
3. Improve the functions step by step
三、活动总结
III. Summary
本次活动以讨论为主，参与者以兴趣小组为单位，所有参与者能够对同一个问题提出自己的想法和意见，更具有针对性，也有利于开发活动的推进。
This team-event focuses on discussion. Participants are organized as a team. Every participant can put forward his/her own ideas and suggestions on the same topic. The team work is more effective, and it will help to push on the development
. 这次活动只是个开始，我们希望能够真正通过这样的方式，开发出能够为同学们服务的应用程序。 The first team-event is just the beginning. We hope more applications serving students could be discussed and developped in this way.
在以后的活动中，可以针对小组成员在开发过程中遇到的问题进行讨论、也可以把开发过程中的经验教训分享给大家。由于兴趣小组刚建立，大家都有自己浓厚的兴趣和新奇的想法，感兴趣的小组成员一直留下来讨论到12点，走了一部分MM和GG，给我们几个夜猫子来个小合照吧。 In the future activities, team members could discuss problems found during developing applications, and the experience could be shared too. Since this is the first time that team members get together, everyone is intrested in Android and wants to share their ideas with each other, some of us keep discussing till 12 pm. Some girls and boys left early. At last, take a picture of us night owls.
