Embodiment one

FIG. 1 shows a first implementation process of the wireless network data restoration method provided by Embodiment 1 of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown.

In the embodiment of the present invention, the method is applied to a smart terminal, and the smart terminal has a function of connecting to a wireless local area network (WLAN). Preferably, the smart terminal includes, but not limited to, smart phones, tablet computers, learning machines, music players (such as MP3, MP4, etc.), PDA smart terminals, vehicle-mounted smart terminals, and wearable devices. Before flashing or restoring factory settings, the smart terminal will read the wireless network configuration information and permission information in the first wireless network configuration file, and store the wireless network configuration information and permission information together in the backup file. The wireless network configuration information is preferably Wi-Fi configuration information.

As shown in Figure 1, the method includes:

In step S101, when a wireless network data restoration instruction is detected, a first wireless network configuration file is obtained.

Wherein, the first wireless network configuration file is data/misc/wifi/wpa_supplicant.conf file, which is used to store Wi-Fi configuration information and permission information.

In the embodiment of the present invention, since the smart terminal after flashing or restoring factory settings has cleared the first wireless network configuration file before flashing or restoring factory settings, if the smart terminal after flashing or restoring factory settings has not connected to Wi-Fi The wireless network does not have the first wireless network configuration file inside, and the obtaining the first wireless network configuration file includes:

Judging whether the first wireless network configuration file exists in the smart terminal;

If yes, then obtain the first wireless network configuration file;

Otherwise, trigger a wireless network connection function to generate the first wireless network configuration file.

When the smart terminal has the first wireless network configuration file, directly obtain the first wireless network configuration file; otherwise, by enabling Wi-Fi once, the wireless network connection function (such as enabling the wireless network connection on the smart terminal function, not necessarily connected to the network), and automatically generate the first wireless network configuration file in this way, that is, the data/misc/wifi/wpa_supplicant.conf file.

Different Android devices use different network ports. Therefore, in order to ensure the usability of the restored wireless network data, at the same time assign the ctrl_interface attribute value in the data/misc/wifi/p2p_supplicant.conf file to the ctrl_interface in the data/misc/wifi/wpa_supplicant.conf file.

In step S104, read the permission information in the backup file, and modify the permission information in the first wireless network configuration file to the read permission information.

After assigning the ctrl_interface attribute value in the data/misc/wifi/p2p_supplicant.conf file to the ctrl_interface in the data/misc/wifi/wpa_supplicant.conf file, restore the factory settings or Modify the permission information of the current data/misc/wifi/wpa_supplicant.conf file with the permission information of the wpa_supplicant.conf file before flashing.

In step S105, after the wireless network configuration information, port attribute information, and authority information of the first wireless network configuration file are modified, restart the smart terminal.

When the Wi-Fi configuration information, permission information, and ctrl_interface attribute information in the data/misc/wifi/wpa_supplicant.conf file of the intelligent terminal after restoring the factory settings or flashing the machine are all modified, restart the intelligent terminal. After restarting, the smart terminal can continue to use the Wi-Fi hotspot used before flashing or restoring factory settings to access the wireless network.

In the embodiment of the present invention, the backup file related to the wireless network data is stored before the smart terminal is reset or the factory settings are restored; after the smart terminal is reset or the factory settings are restored, the current first wireless network configuration file is modified according to the stored backup file. Wireless network configuration information and permission information, and modify the port attribute information in the current first wireless network configuration file according to the port attribute information in the second wireless network configuration file, and finally restart the smart terminal; the restarted smart terminal can be Use the previous Wi-Fi hotspot to connect to the network, so as to restore the previously saved wireless network data on the smart terminal, so that the smart terminal can continue to use the previous Wi-Fi hotspot connection without resetting after flashing or restoring factory settings The network avoids resetting the network connection of the smart terminal, which greatly improves the user experience.
