Research On Storage Technology Of Android Operating System

With the rapid development of mobile communication technology, smart phones become more powerful, have more and more extensive applications.Mobile Internet is showing a rapid development nowadays, Android operating system is a leader in the mobile Internet.In order to standardize criteria for Android developers, to improve the efficiency of application development, we select Android storage technology for the study. In development of Android applications, reading, writing or accessing to storage is very frequent. Android has its own set of storage mechanism, understanding the mechanism of the principle, using the appropriate interface for the development of efficient applications is very useful. This article firstly research the storage mechanism on the Android operating system, analyze the components of storage, such as Content Provider and SQlite, in explaining its internal mechanism, combined with examples, we show how to use the Content Provider and SQlite. Meanwhile, the Android operating system architecture, interfaces, components and development environment also be made a detailed introduction in this article. In order to verify the usefulness of research results, this article implements a specific Android application - Image store and viewing system. The application uses a number of storage technologies mentioned in this article, to optimize the storage and viewing of images and obtains good results.Based on the Android storage technology research and implementation of Image store and viewing system. we hope to provide useful lessons for the future development of similar storage-related applications.
