摘 要

城市道路上经常会出现垃圾堆放、窨井盖丢失、障碍物等破坏城市市容市貌、影响市民正常出行的状况，更有甚者会产生危险，威胁市民生命财产安全。传统的手段已经不能满足我们现代生活的需要，因此我们需要一种全新的方法，能够充分调动市民的积极性，推动大众参与城市市容市貌的建设工作，加强反馈信息处理的及时性和有效性，分清责任人，加强监管，为城市环境建设助一臂之力。

我们Road Snap团队将分为三大部分进行开发，分别为Android客户端、iOS客户端和后台服务器端。移动端负责用户信息的显示和传递，后台信息的传输和地理位置的服务。后台负责数据的接收、存储和发送。

我负责对Android端的App进行开发工作。由于Android操作系统拥有庞大的用户量，可以使更多的市民参与到城市道路环境信息采集的工作中，有利于调动市民积极性。在设计本App的过程中，我们将加入Google在2014 I/O大会上提出的Material Design 设计风格，有效地帮助用户使用App。同时，我们对Android的一些技术进行深入研究，理解Android系统API使用方式和工作原理。本文对Android客户端的开发进行较为深入的研究，并给出了简要的实现过程。

ABSTRACT

Rubbish bumps, lost manhole covers, barriers and other phenomenon often showed up on our streets, they might probably do harm to the appearance of the city and effect the traffics, some of which may even cause danger, and threaten the safety of citizens’ lives and properties. Traditionally, relative departments would routinely check the states of the roads and do some cleanings for the streets, and this would be one of the solutions. Besides, if citizens could find those problems, they could also report the states of the roads to the relative departments as well as they can supervise those departments so that they could do their jobs in time. Unfortunately, traditional solutions cannot always get the job done just in time. First of all, the reference to the relative departments is not clear so each and every one of them would say that are not their jobs so they could do nothing. What’s more, citizens could not get their feed backs in time, and this would reduce the activity of citizens’ attitude to the build of the appearance of our city. In the long term, it is not good for the work of the build of the appearance of the cities. Thus, we are in need of a brand new way to help us to motivate our citizens and let them participates in our work of the build of the appearance of the cities. We need to makes feedbacks more in time and efficient. We need to know who is responsible for the problems and we need stronger authority of supervision. If we can get those parts done, we can definitely get a push to our work of the appearance of our cities.

As the economy and technology rapidly developing in our time, techs are play an increasingly important job in people’s daily lives. Technology change the way people live their lives while the emergency of smartphones makes it go further. In the year of 2008, Google launched the first smartphone running Android operating system, which flags the entrance of the Android into the smartphone playground. The advantage of open source and free of Android makes it the most widely used smartphone operating system in the market in a very short time. While the upgrades Google leased to the Android, Android become the best smartphone operating system ever.

Based on what we have review above, our Road Snap team will make Android one of our platforms to release our services, and I will be the one to develop Android app. By the advantage of the population of Android operating system, we can quickly gain large amount of users and get more people into our project to help us collect the states of our streets. It can motivate citizens as well. We would use Material Design announced by Google in 2014 Google I/O in our Android app to help our users to know how to interact with our app and make our app looks better. In the meantime, we would do some deep research in Android techs, learn the principles and ways of Android APIs. This article will do some deep research in the coding of Android apps and would reveal some simple examples.
