Based On The Android Platform For The Self-service Training Application Software Development

It was only for hundreds of years, bell invented the telephone to the first smartphoneSimon was born, the world has witnessed the rapid development of human science andtechnology. Today’s society, the smart phone plays an indispensable role in People’s Dailylife.In many smart phone system, the only open source system is Android, which hasissued several years later. Android has taken the important position in today’s smartphonemarket. Since the first Android smartphone released a few short years ago, Android marketshare the first rapidly occupies in the world, more than ever the occupy of the top positionof the Symbian system. On the one hand,the Android system is based on Linux and opensource. on the other hand Android has good function of openness and extensibility, whichis widely used in tablet or smartphone.To sum up, this article will take the android smartphone operating system as the mainobject of study. In this paper, Research work is mainly reflected in the following aspects:1. Introduce topic background, including the research of Android system, the presentsituation and development trend of smartphone operating system from home and abroad,and analysis their respective advantages and disadvantages.2. According to the principle of Android system architecture,build the Androiddevelopment environment, and make a good foundation of design the Android applicationon theoretical and technical reserves aspects.3. Design the Android application.4.J2ee is used for designing the software and10kinds of current core technology iswidely uesd:(1) the technology of image asynchronous loading;(2) lightweightdata-interchange format json;(3) the technology of XML layout management;(4) thetechnology of SharePreference preservation system configuration;(5) the technology of theActivity component page display system;(6) Mediaplayer video technology;(7) thetechnology of the Intent and IntentFiler page jump;(8) the technology of Camera takingpictures;(9) list of Listview display technology;(10) the technology of XML resource filesystem resource management.This study focus on solving these disadvantages: the reaction speed of today’s mostmobile training learning software is slow, the data flow is huge and the cost is high. Thisresearch training platform software, which is applied in the actual engineering project, wona good user experience.
