1 Summary. Android is a software platform and operating system based on the Linux core, which is widely used in smartphones, tablets and other fields with its unique openness. In recent years, e-commerce has developed rapidly, and transactions through the Internet have become a trend. The combination of the two has given rise to mobile e-commerce with great potential for development.
This system is mainly to explore the combination of Android and e-commerce, taking mobile phones as an example to realize user browsing, searching, purchasing goods and other functions. This ** selects the sqlite database to realize the functions of adding, deleting, modifying and checking the goods in the database, and manage customer orders. The system is more mobile and cross-platform than the usual shopping system. Through testing, it has been able to run and use its various shopping processes on Android phones.
Keywords: android;sqilte；E-commerce;Online shopping.
2. System analysis, design and implementation.
2.1. System requirement analysis and topic selection basis.
2.1.1 The purpose of the topic.
The project called for the design and implementation of a mobile phone network based on the Android platform**. With the continuous development of the Internet, the network occupies an irreplaceable position in people's lives. In the past, people often browsed and purchased goods through the shopping system of the PC, so that they could enjoy the fun of shopping without leaving home. But these have become more and more unable to meet people's growing needs for life, we want to be able to enjoy the movement of goods anytime and anywhere, whether it is discounted or some other information, which makes us need a software that can be installed on mobile phones, which is convenient for people to travel and carry, and convenient for people to browse goods and shop anytime and anywhere. This kind of software also increases the probability of customers making a purchase and creates greater profits for merchants, so I chose to design this software. Because I myself am very fond of online shopping, such software is not only convenient and fast to operate, but also can serve the public to the greatest extent, and is an indispensable service software for people's lives now.
2.1.2. The significance of the topic selection.
The design and implementation of the mobile phone online based on the Android platform has changed people's previous shopping patterns, people do not have to be limited to shopping in front of the computer, nor do they need to deliberately find time to browse goods on the Internet, or shop. As long as you have an Android phone, you can view the goods anytime and anywhere, no matter where and when the goods are produced, you can easily find them through your mobile phone, move your fingers, which not only increases the efficiency of shopping, but also makes people happy, and will no longer be troubled because they want to buy their favorite goods but can't find them. People may have the longest waiting time in a day's life, but with the acceleration of the pace of life, many people are not willing to waste their time waiting in vain, with this software, people can use their waiting time to do something they are interested in, such as shopping for a favorite clothes, adding a new outfit to the upcoming spring, etc.
In short, in today's efficient life, how to save time and how to use time efficiently has become a problem that everyone will think about. Based on the Android platform, the mobile phone online ** just saves people time for shopping, so that they can invest this time in work or other aspects of life, without time restrictions, shopping can become more convenient and interesting.
2.2. Overall design of the system.
2.2.1. Overall functional design.
The overall functions of the system include registration and login, browsing and searching, viewing details, buying now, adding to cart and checkout, and my personal information.
The overall functional modules of the system are shown in Figure 2-1 below
Figure 2-1 Diagram of system function modules.
2.2.2. Overall process design.
The overall process of the system is: first open the login page, then log in to the homepage after registration, you can browse and search for your favorite products to view the details on the homepage, and you can buy immediately or temporarily add to the shopping cart on the product details page. On the shopping cart page, you can select the items you want to purchase for checkout, and you can view the purchase details of all purchased items in My Orders on My Page.
The overall flow chart of the system is shown in Figure 2-2 below

4 Summary. 1. Know how to quickly master a language. In the process of learning J**A, Mr. Lou first asked us to quickly browse the textbook, find out what we don't know, and then do experiments with questions, so that we can deeply understand the content in the textbook, which is very efficient
2. Have experience in engineering. Through the project practice, I have a basic understanding of the steps and methods of doing the project, that is, feasibility analysis, demand analysis, overall design, detailed design, coding testing, operation and maintenance, especially a deeper understanding of the demand analysis, which lays a foundation for future scientific research and learning.
3. Basic grasp of the general process of Android application development. Basic knowledge of the use of common controls, as well as the listening methods of their events. Learning Android is not only an understanding of cutting-edge development technology, but also an improvement of programming knowledge.
4. By learning a series of basic knowledge such as Android controls, layouts, activities, services, etc., I have a general understanding of the development of the entire Android. For example: to the layout (or control), in the learning interface, I found that Android provides us with a good similar reflection mechanism, through the configuration file under the layout folder, you can quickly form an interface, in the configuration file you can set properties or styles are very fast and convenient, for the more special interface can also be embedded in the specified interface by processing, you can also directly create a view through j**a** to add, but this way is more complicated.
5. For some clicks, selections, buttons, etc., the jump intent management between interfaces is managed, and the data is transmitted between interfaces through bundles.
Android is a very wrong mobile phone system, it is simple to use, and you can choose the version that suits you according to your needs, which is very convenient. I want to learn more about Android, and in the future, the Android system will be developed more user-friendly and more comfortable to use.
