1)Adicione como variável da activity;
private WifiConnectionReceiver mWifiConnectionReceiver;
2)se registrar no oncreate() precisa destruir no onDestroy(), onCreate(){
registerReceiver(mWifiScanReceiver, new IntentFilter(getIntentFilterForWifiConnectionReceiver());
}
onDestroy(){
unregisterReceiver(mWifiScanReceiver);
super.onDestrou();
}
3) se registrar no onStart()
destrua no onPause()
Semelhante ao código acima
When you do connect to a Network, do you get a prompt in the notification bar ? Or do you directly connect to the WiFi from within the app?
I am seeing a notification saying "WiFi options available" and then clicking on takes me to the WiFi Settings..I would like this process to work directly within the app...any clue?
@Akshshr No, after android 8 version, you need to ask the user to choose the wifi (security)
