The sample barcode value is as follows.

- Wi-Fi SSID : WIFI_123
- Wi-Fi Password : 12345678
- Wi-Fi encryption type : WPA
Data need to be parsed in onActivityResult to get the password and SSID.
You can use the android.net library to connect to wifi using the password and SSID.
The first step is to create a WifiNetworkSpecifier with the SSID and password obtained from the barcode.
The second step is to create a network request with the wifiNetworkSpecifier created in the previous step.
NetworkCallback is the base class for NetworkRequest. Used for notifications about network changes. Should be extended by applications wanting notifications.
If a network matching the SSID is found, connect to wireless network option will be shown. After clicking connect button, If the password is correct, it will be successfully connected to the network.
The following alert will be shown if a network matching the SSID cannot be found.
