Design and implementation of network packets collection tools based on the android platform

In this paper, the android system architecture and security mechanism are introduced briefly, and a network data collection program based on the android platform is proposed. In this program, the Libpcap function library based on BPF capture mechanism is packaged as dynamic library by JNI technology. At last, the functions of network data collection and real-time display are implemented on the android device, which is the foundation for the further network analysis.
