Error de autenticación wifi en Android

Question

Estoy desarrollando una aplicación que utiliza Wifi en Android. Cada vez que ingreso una contraseña incorrecta mientras me conecto a wifi, no recibo ninguna notificación de autenticación inválida. Simplemente sigue reintentando conectarse. El mismo comportamiento se encuentra en la configuración wifi inalámbrica.

¿Hay alguna manera de descubrir que la autenticación de WiFi ha fallado?

WifiManager.EXTRA_SUPPLICANT_ERROR - Nunca me sale esto ..

Answer 1

Este código funciona:

IntentFilter mIntentFilter = new IntentFilter(); 
mIntentFilter.addAction(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION); 
registerReceiver(receiverWifi, mIntentFilter); 


class WifiReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context c, Intent intent) { 
     String action = intent.getAction(); 
     if(action.equals(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION)){ 
      Log.d("WifiReceiver", ">>>>SUPPLICANT_STATE_CHANGED_ACTION<<<<<<"); 
      SupplicantState supl_state=((SupplicantState)intent.getParcelableExtra(WifiManager.EXTRA_NEW_STATE)); 
      switch(supl_state){ 
      case ASSOCIATED:Log.i("SupplicantState", "ASSOCIATED"); 
       break; 
      case ASSOCIATING:Log.i("SupplicantState", "ASSOCIATING"); 
       break; 
      case AUTHENTICATING:Log.i("SupplicantState", "Authenticating..."); 
       break; 
      case COMPLETED:Log.i("SupplicantState", "Connected"); 
       break; 
      case DISCONNECTED:Log.i("SupplicantState", "Disconnected"); 
       break; 
      case DORMANT:Log.i("SupplicantState", "DORMANT"); 
       break; 
      case FOUR_WAY_HANDSHAKE:Log.i("SupplicantState", "FOUR_WAY_HANDSHAKE"); 
       break; 
      case GROUP_HANDSHAKE:Log.i("SupplicantState", "GROUP_HANDSHAKE"); 
       break; 
      case INACTIVE:Log.i("SupplicantState", "INACTIVE"); 
       break; 
      case INTERFACE_DISABLED:Log.i("SupplicantState", "INTERFACE_DISABLED"); 
       break; 
      case INVALID:Log.i("SupplicantState", "INVALID"); 
       break; 
      case SCANNING:Log.i("SupplicantState", "SCANNING"); 
       break; 
      case UNINITIALIZED:Log.i("SupplicantState", "UNINITIALIZED"); 
       break; 
      default:Log.i("SupplicantState", "Unknown"); 
       break; 

      } 
      int supl_error=intent.getIntExtra(WifiManager.EXTRA_SUPPLICANT_ERROR, -1); 
      if(supl_error==WifiManager.ERROR_AUTHENTICATING){ 
       Log.i("ERROR_AUTHENTICATING", "ERROR_AUTHENTICATING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); 
      } 
     } 
    } 
}
