The determination module 103 receives the WifiConfiguration object and determines the SSID attribute in the WifiConfiguration object. When the determining module 103 determines that the SSID attribute in the WifiConfiguration object is a hidden SSID attribute, the configuration file generating module 104 generates a corresponding configuration file for corresponding parameters transmitted to the Netd service, where the corresponding parameters include a "start Soft AP" parameter, the configuration file includes a "hidden SSID" parameter, and the parameter value of the "hidden SSID" and the parameter value of the "start Soft AP" are both 1. According to the above parameter values, the hostapd calling module 105 calls hostapd service according to the configuration file, and starts Soft AP in non-broadcast SSID mode. When the determining module 103 determines that the SSID attribute in the WifiConfiguration object is a broadcast SSID attribute, the configuration file generating module 104 generates a corresponding configuration file for corresponding parameters transferred to the Netd service, where the corresponding parameters include a "start Soft AP" parameter, the configuration file includes a "hidden SSID" parameter, a parameter value of the "start Soft AP" is 1, and a parameter value of the "hidden SSID" of the configuration file is 0. According to the above parameter values, the hostapd calling module 105 calls hostapd service according to the configuration file, and starts Soft AP broadcasting SSID mode.
In summary, in the embodiment of the present invention, the information of whether the SSID is hidden and inputted by the user is received in the Android system, so that the Netd service is controlled to generate the corresponding configuration file, thereby starting the Soft AP in the broadcast/non-broadcast SSID mode, and the method and the device are simple in process, can effectively solve the SSID hiding problem of the wireless Soft AP, and are beneficial to protecting the privacy of the user network information.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
