This method is deprecated now from now starting with Android Q  Try This will really help  if  Build VERSION SDK INT  lt  Build VERSION CODES Q      if build version is less than Q try the old traditional method                     if   wifiManager isWifiEnabled                              wifiManager setWifiEnabled true                           btnOnOff setText  quot Wifi ONN quot                          else                           wifiManager setWifiEnabled false                           btnOnOff setText  quot Wifi OFF quot                                            else     if it is Android Q and above go for the newer way    NOTE  You can also use this code for less than android Q also                     Intent panelIntent   new Intent Settings Panel ACTION WIFI                       startActivityForResult panelIntent  1
