With the rapid development of the Internet and the Internet things, people around filled with colorful network information. But it is difficult to achieve all useful information timely and accurately.Currently an context awareness system is required that can meet the needs of different users and provide efficient, timely and personalized service in different environments so as to improve people’s daily lives and working efficiency. In recent years, researchers of the related fields has studied the related theory, method, application of the context awareness system and build some context awareness system, such as smart home, smart classroom, and it has become a hot research topic of the field of artificial intelligence. But the field of context awareness is researched relatively small in the Android mobile platform, not even build a separate system of context awareness for the Android mobile platform for daily lives of people. Because Android mobile platform has been widely used and context awareness theory is relatively mature, researching context awareness based on Android mobile platform is very necessary, and has broad market prospects and the theoretical value.This paper researched the relative technology of context awareness system based on the Android mobile platform and completed the framework design of the context awareness system in mobile platform. It also researched basic theory, relative algorithm and implementation process of the reasoning and service module of context awareness based on this system framework module and solved conflict problem of the rule-based reasoning in context awareness system. Finally the indoor positioning method based on location fingerprint-based localization algorithm was optimized. The main research works in this paper are as follows:(1)The research status at home and abroad of context awareness technology and the problems in the mobile platform context awareness technology was summarized.(2)This paper analysed the system structure of Android platform, introduced the development history of Android platform and the application components of Android platform.(3)For context awareness system, this article elaborated the concept of context awareness and proposed context awareness system of mobile platform by introducing the concept of context awareness service and interactive model.(4)The system structure of context awareness was designed for mobile platform. According to the context awareness system framework, context awareness system is divided into context awareness reasoning module and service module and the basic definition and algorithm of these tow modules were designed and elaborated. Furthermore, this article solved inference conflict problem of context awareness firstly and then proposed an algorithm to solve inference conflict. Finally, the Wi-Fi positioning algorithm based on location-based fingerprint was optimized.(5)According to the relative theory of context awareness, this article implemented context awareness system in Android mobile platform, completed the rule-based reasoning and context awareness service and solved conflict problem of the context awareness. Finally, the rule-based reasoning, context awareness service was analyzed and the Wi-Fi positioning algorithm based on location-based fingerprint was implemented.
