在Android的无线身份验证错误 [英] Wifi Authentication Error in Android

问题描述

我正在开发在Android中使用WiFi的应用程序。每当我输入错误的密码，同时连接到无线网络，我没得到任何通知无效的认证。它只是不断尝试连接。同样的行为在wifi无线设置中。

I am developing an application using Wifi in Android. Whenever I enter wrong password while connecting to wifi, I dont get any notification for invalid authentication. It just keeps on retrying to connect. Same behavior is found in wifi wireless setting.

有没有办法找到无线验证失败??

Is there any way to find that Wifi Authentication has failed??

WifiManager.EXTRA_SUPPLICANT_ERROR - 我从来没有得到这个。

WifiManager.EXTRA_SUPPLICANT_ERROR -- I never get this..

推荐答案

这code工作：

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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
            }
        }
    }
}

<receiver
    android:name=".MyActivity$WifiReceiver"
    android:process=":remote" >
</receiver>
