Hidden Wi-Fi Auto-connecting System Based on Android ROM-Level

This paper presents a method for the realization of hidden Wi-Fi auto-connect system based on android ROM-Level. Under this system, two Android devices can establish a Wi-Fi connection at a specific time, and do not display a Wi-Fi icon when the connection is successfully established. Among them, write the program of BroadcastReceiver in the Android framework layer to realize the control and management of Wi-Fi module, modify Android native calculator program to achieve user configuration function, and modify system application of SystemUI to realize the function of shielding Wi-Fi icon. Since the code is written based on the ROM-Level and the entire process is user-insensitive, the system maintains a high security and can provide new application scenarios.
