How does Android get the WiFi name, that is, the SSID?

You can use wifimanager and wifiinfo to obtain the current Wi-Fi connection information.

 
Wifimanager = (wifimanager) getsystemservice (wifi_service); wifiinfo = wifimanager. getconnectioninfo (); log. D ("wifiinfo", wifiinfo. tostring (); log. D ("SSID", wifiinfo. getssid ());
 

Remember to add a license to the manifest File

 
<Uses-Permission android:Name="Android. Permission. access_wifi_state"></Uses-Permission>
 

If you do not want to get the current connection, but want to get the connection in the WiFi settings

Available

 
Wifimanager. getconfigurednetworks ()
