Abstract: Vulnerability plays a critical role in Android security. Therefore it is very meaningful to do research on vulnerability detection techniques, which can enhance Android security and protect user’s privacy. In this paper, we firstly summary the number trends and categories of Android vulnerabilities from 2008 to 2015. Then we analyze the research progress of Android security from 2012 to 2014 and propose an overview of Android vulnerability detection techniques. After that, we detail the techniques frequently using in current researches, such as taint analysis, reachable path discovery, symbolic execution and fuzzing test. In addition, we also focus on the techniques combining static analysis and dynamic test such as concolic testing and directed fuzzing. At last, we conclude the status quo and open source tools in Android vulnerability detection, and propose valuable issues which are worth further studying.
