FlowDroid is an open-source tool based in soot, a framework dedicated to analyzing and translating Java bytecode for easier analysis. The tool handles the nuances of Android app lifecycles (like onCreate, onStart, onPause, and others) and its UI components during analysis and performs taint analysis that is:

  • Context-sensitive: Distinguishing between calls to the same method based on their specific execution contexts.
  • Object-sensitive: Identifying individual objects, even when they're of the same class.
  • Flow-sensitive: Recognizing the sequential order of code execution.

FlowDroid can be used in two ways: as a standalone command line tool for quick analyses or as a library for more complex investigations. In addition to performing taint analysis, FlowDroid can also generate call graphs, as illustrated in this blog post.
