Analysis And Design Of Translation Software Based On Android

At present, the electronic dictionary industry is developing more and more quickly. With the development and popularization of language, online translation software is constantly optimized to the market. Android occupies the market of global smart phone operating system in the first place. If online translation is based on android, its excellent performance can give language learners a great convenience.At first, the paper introduces the research background of the project and the development status at home and abroad, and expounds the social significance and value of the translation client. Then we introduce the Android operating system and related technology in detail, for example, C / S mode as the overall structure of the system, MVC mode as the program framework of the system, SQLite as the system database, and online translation technology uses Google API. And then we analyze the functional requirements and nonfunctional requirements of the translation system.Functional requirements include learning functions and auxiliary functions, learning functions include query translation, pronunciation, view vocabulary, learning words;auxiliary functions include viewing history, management of thesaurus, English information, settings and so on. Non-functional requirements include mainly system performance, network transmission and user experience requirements. And then according to the system requirements for functional modules and system network architecture, system framework, system database, system interface, the outline of the design. Finally, the design function of the App client is designed, and the shortcomings of the design and the optimization scheme are put forward.In the process of project development, I participated in the requirement analysis,outline design and testing, and independently analyzed and designed the online query module, offline query module, pronunciation module, vocabulary module, word learning module, lexical management module, View history module, English information module, lock screen translation module, user settings module. The software in the test, each function module can run successfully, the user experience better, and to meet the needs of the user query translation, to achieve the original design.
