Android-连接到已知的隐藏Wi-Fi网络 [英] Android - connect to known hidden Wi-Fi network

问题描述

我需要以编程方式连接到隐藏的Wi-Fi网络. 我知道它是SSID，安全类型和密码. 由于某种原因，我无法连接它.

I need to connect to hidden Wi-Fi network programmatically. I know it's SSID, security type and password. For some reason I can't connect it.

如果未隐藏，我可以连接到同一网络.

I can connect to the same network if it's not hidden.

这是我的代码:

// configure the network
private void saveWPANetwork(WiFiNetwork network){     
    WifiConfiguration conf = new WifiConfiguration(); 
    conf.SSID =network.getSSID(); 
    conf.hiddenSSID = true; 
    conf.status = WifiConfiguration.Status.ENABLED; 
    conf.preSharedKey =network.getPassword(); 
    conf.priority = 9999; 
    wifi.addNetwork(conf); 
    wifi.saveConfiguration(); 
}

// connect it
protected boolean connectToVaildNetwork() { 

    List<WifiConfiguration> list = wifi.getConfiguredNetworks(); 
    if(list == null) 
        return false; 

    for( WifiConfiguration i : list ) { 
        for (WiFiNetwork network : config.wiFiNetworksDetails) { 
            if(network.getSSID().equalsIgnoreCase(i.SSID)){ 
                wifi.enableNetwork(i.networkId, true); 
                return wifi.reconnect(); /// STRANGE BUT IT ALWAYS RETURNS TRUE, EVEN IF DEVICE IS NOT CONNECTED TO THE  HIDDEN NETWORK! 
            } 
        } 
    } 
    return false; 
}

推荐答案

这个答案可能很晚，但是如果有人需要，我还是会贴出来. Android 4.4.2经过测试.请注意，隐藏网络需要更长的时间才能连接(在我的测试中，连接时间约为10到15秒)

This answer maybe late but I still post it in case of someone need. Android 4.4.2 tested. Notes that hidden networks take longer time to connect (for my test it was around 10-15s)

wifi.reconnect()== true表示已成功请求您的命令，并不表示已连接wifi.

wifi.reconnect() == true means that your command has been requested successfully, it does not mean that wifi is connected.

public void setWifiConfig(String ssid, String sharedKey) {
    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = "\"" + ssid + "\"";   // Please note the quotes. String should contain ssid in quotes

    conf.preSharedKey = "\"" + sharedKey + "\"";

    conf.hiddenSSID = true;
    conf.status = WifiConfiguration.Status.ENABLED;
    conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);

    WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);

    wifiManager.addNetwork(conf);

    List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
    for (WifiConfiguration i : list) {
        if (i.SSID != null && i.SSID.equals("\"" + ssid + "\"")) {

            wifiManager.disconnect();

            wifiManager.enableNetwork(i.networkId, true);

            wifiManager.reconnect();

            wifiManager.saveConfiguration();
            break;
        }
    }
}
