Mobile Learning Platform Research And Implement Based On Android

The rapid development of China's economy,people demand more and more need for knowledge through daily study to satisfy the society to the skills and knowledge required,information technology and computer network technology has been developed to a new stage,the mobile client has penetrated into various fields,so that they can make mobile learning possible,mobile learning convenience to the learning whenever and wherever possible,meet the people's needs for lifelong learning.This subject from this point of view and in view of the actual demand of mobile learning,proposed the mobile learning system based on Android relevant,practical significance.To the development of practical applications as background,uses the current network development mature mainstream technology,combined with Java and SQL database technology,design and develop a mobile learning system.By using the principle and method of software engineering,firstly,on the requirement of the development system,to get the functional requirements of the system,and the use of UML object-oriented modeling technology,gives the use case diagram and class diagram by the system,and carried on the overall design of the system.Then the function modules of the system were designed,the system is divided into several main function module,the design is also analyzed and the key technology of the design of system architecture design and database design etc..In the video coding module search algorithm of motion estimation and improve the corresponding optimization,to compare the algorithm in reference software algorithm and the improved scheme,the improved algorithm is more effective than the reference algorithm in software of video quality and coding time has a certain improvement.Then,for H.264 video data encapsulation strategy are comprehensively analyzed,designed by packaging process and strategy of RTP,according to the RTP package H.264 video stream data on the error control in transmission process design of a Qos solution.In the part of system implementation including the choice of development environment,to achieve database access system,the main achievement of specific functional modules,module to realize the key code.Finally,the system was tested,and the test results are analyzed,the system test results show that,the system achieved very good user requirements,the overall performance of the system design objectives.The mobile learning system has friendly interface,convenient operation,reliable and stable system,the application of information technology in education and training,equipment has become one of the great development potential of the work,fully embodies the necessity of the education industry development of mobile learning,but also for the development of similar systems for future reference and help.
