For GUI programs, like Android apps, the program functionalities are encapsulated in a set of basic components, each of which represents an independent function module. When interacting with an app, users are actually operating a set of components. The transitions among components, which are supported by the Android Inter-component communication (ICC) mechanism, reflect the skeleton of an app. To effectively resolve the source and destination of an ICC, both the correct entry-point identification and the precise data value tracking of ICC fields are required. However, with the wide usage of Android Fragment, the entry-point analysis usually terminates at an inner fragment but not its host component. Also, the simply tracked ICC field values may become inaccurate when data is transferred among multiple methods. In this paper, we design an ICC resolution tool \textit{ICCBot}, which resolves the component transitions that are connected by fragments to help the entry-point identification. Besides, it performs context-sensitive inter-procedural analysis to precisely obtain the ICC carried data values. Compared with the state-of-the-art tools, \textit{ICCBot} achieves both a higher success rate and accuracy. \textit{ICCBot} is open-sourced at https://github.com/hanada31/ICCBot.
