android 连接wifi

前几天在做一个远程控制app用来获取远端设备wifi列表并控制远端设备连接wifi，做下简单记录，主要代码如下：

//创建一个WifiConfiguration

public WifiConfiguration createWifiInfo(ScanResult scan, String password) {
    WifiConfiguration config = new WifiConfiguration();
    config.hiddenSSID = false;
    config.SSID="\"" + scan.SSID + "\"";
    config.status = WifiConfiguration.Status.ENABLED;
    DLogUtils.e(TAG,"capabilities : "+scan.capabilities+" ,ssid : "+config.SSID);
    if (scan.capabilities.contains("WEP")) {
        DLogUtils.e(TAG,"createWifiInfo WEP ");
        config.hiddenSSID = true;
        config.wepKeys[0] = "\"" + password + "\"";
        config.allowedAuthAlgorithms
                .set(WifiConfiguration.AuthAlgorithm.SHARED);
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
        config.allowedGroupCiphers
                .set(WifiConfiguration.GroupCipher.WEP104);
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
        config.wepTxKeyIndex = 0;
    } else if (scan.capabilities.contains("WPA")) {
        DLogUtils.e(TAG,"createWifiInfo WPA ");
        config.preSharedKey = "\"" + password + "\"";
        config.hiddenSSID = true;
        config.allowedAuthAlgorithms
                .set(WifiConfiguration.AuthAlgorithm.OPEN);
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        config.allowedPairwiseCiphers
                .set(WifiConfiguration.PairwiseCipher.TKIP);
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        config.allowedPairwiseCiphers
                .set(WifiConfiguration.PairwiseCipher.CCMP);
        config.status = WifiConfiguration.Status.ENABLED;
    }else {
        DLogUtils.e(TAG,"createWifiInfo else ");
        config.allowedAuthAlgorithms.clear();
        config.allowedGroupCiphers.clear();
        config.allowedKeyManagement.clear();
        config.allowedPairwiseCiphers.clear();
        config.allowedProtocols.clear();
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    }
    return config;
}

//添加网络

int networkId = wifiManager.addNetwork(createWifiInfo(sr,wifi_password));

//连接网络

private boolean connectToWifi(int netId){
    boolean enableNetwork = wifiManager.enableNetwork(netId, true);
    DLogUtils.e(TAG,"connectToWifi netId : "+netId+" ,enableNetwork : "+enableNetwork);
    return enableNetwork;
}
