Design And Development Of Japanese Learning System Based On Android

With the deepening of Sino-Japanese exchanges,the number of people studying in Japan and traveling to Japan is increasing.According to the statistics of the Japan Foundation,China has become the world's largest Japanese lea rning country,and Japanese teaching is second only to English teaching.Use online learning applications to make learning endless.Mobile learning technology enables a geographically unlimited,time-independent learning style,and is fast and easy.In addition to traditional classroom teaching,decentralized learning has become one of the most important learning methods for modern people.In the application market,the number of Japanese learning APPs is small and relatively simple,and there is no comprehensive learning method such as listening,speaking,reading and writing in Japanese learning.Based on the needs of users' comprehensive learning,the system integrates Japanese vocabulary learning,reading learning,listening learning,and oral learning.An APP satisfies the needs of users for comprehensive learning and is convenient for users to operate.This paper introduces the development and implementation of Android-based Japanese learning system from the four stages of requirements analysis,system design,system implementation and system testing,and summarizes the development experience and problems.In the demand analysis,the functional requirements and non-functional requirements are mainly introduced.Analyze functional requirements based on the roles of learning users and administrators.Non-functional requirements analysis focuses on system performance requirements analysis and system security requirements analysis.System design,mainly described: system framework design,main functional design,database design.The system framework design includes the overall framework of the system and the main technical framework of the system.The main function design includes: vocabulary learning,listening learning,reading learning,oral learning,learning data management,user information management,administrator account management,and a total of seven main functions.The database design includes: database summary design and table structure design.The system implementation includes: the system development environment,the key technologies involved in the system,the user's personal center,vocabulary learning,listening learning,reading learning,and oral learning.The article tested system functionality and system performance.Functional testing use s a combination of virtual machine and real machine testing.The performance test is based on the Alibaba Cloud mobile test platform for real machine testing,and the system is improved based on performance test results.
