Android Smartphone Operating System Based On Arm Platform Application Development

In recent years, with the appearance of smart phones, development of the operating systems for foe handheld devices has attracted more and more attention. In the past, the specifications and developments of the handheld devices are usually defined by the vendors in a propritory method. But in 2007,Google launched a complete smart phone operating system which is the first designed for mobile devices-Android. The emergence of Android caused widespread interest in mobile terminal industry, many scholars began to study the android system, promotting the development of android.Although google android source code has been open for some time,there are many foreign expert research and analysis android system and achieved many significant resluts. But in the country, android system has just appeared and there are litter Chinese data related to android system. Only in recent year, android system has been developed. Because of objective factors, the business' research and development capabilities of Android system is stronger than the college. The task of the topic is to analyze the android software architecture, transplant android system to the actual platform, build the execution environment of android system and develop the application of android system.This paper focuses on the android software architecture and compares the android system with general embedded Linux system startup process.According to the android software architecture and startup process, building the operating environment of android and applying it. To improve it on the basis of the method about the Linux kernel transplantation, transplanting the Smartphone system to the target hardware platform successfully and to realize the actual operating environment of android. For Android application exploitation, at first experiment with the primary exploitation subassembly of android separately, secondly summarizes the function of each subassembly,thus develop their own subassembly,finally developed a new android user interface interaction procedures on the basis of it. This application realized basically all the function and effect of iOS main interface with android open source software.
