i there way flag if wifi connection got disconnected/ dropped off or if user changed wifi network ?
i need app : connect wifi xyz, if xyz disconnect (flag 1) or dropped off reconnect xyz. user change wifi btopen (flag 2) allow connect , stop service. if user connect xyz again start loop again.
what got far :

i appreciate help. thank you.
check network connected name using
public string getwifiname(context context) { wifimanager manager = (wifimanager) context.getsystemservice(context.wifi_service); if (manager.iswifienabled()) { wifiinfo wifiinfo = manager.getconnectioninfo(); if (wifiinfo != null) { detailedstate state = wifiinfo.getdetailedstateof(wifiinfo.getsupplicantstate()); if (state == detailedstate.connected || state == detailedstate.obtaining_ipaddr) { return wifiinfo.getssid(); } } } return null; } if name matches networkssid, i.e. xyz, resume service, else if doesn't match, stop service
if getwifiname(this).compareto("xyz") == 0 { //xyz network name on want resume service //code resume } else { //code stop service }
