android 连接指定SSID 的无密码Wifi ，连接不上

Question

1.代码 addNetwork并没有把网络添加保存，也无法连接了

public static WifiConfiguration configWifiInfo(Context context, String SSID, String password, int type) {
        WifiConfiguration config = null;
        WifiManager mWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

                if (existingConfig == null) continue;
                if (existingConfig.SSID.equals("\"" + SSID + "\"")  /*&&  existingConfig.preSharedKey.equals("\""  +  password  +  "\"")*/) {
                    config = existingConfig;
                    break;
                }
            }
        }

Answer 1

"\"" + SSID + "\""

这是干啥？？？
你传进来的就是 String SSID ，为何还要做隐式转换成String？
转换就转换吧，为啥要这么写？
这么写最后SSID是啥？
SSID = "\"" + "ee929" + "\"" = ""ee929"" ???

建议你在
int netId = configuration.networkId;
插入log，打印下你的SSID和password，看看还是不是你要的结果。

Answer 2

失误了，由于连接的wifi设置为隐藏，所以配置少加了一个
config.hiddenSSID=true; 必须加上，才能连接无法扫描到的wifi

 /**
     * 连接wifi
     * @param ssid
     * @param password
     * @param type
     * @return
     */
    public int connectWifi(String ssid, String password, int type) {
        if (removeWifi(getConnectWifiId())) {
            Log.e("disconnectWifi", "true");
        }
        int wifiId = mWifiManager.addNetwork(CreateWifiInfo(ssid, password, type));
        Log.e("wifiId", wifiId + "");
        if (wifiId == -1) {
            Log.e("connectWifi", "false");
            return -1;
        }
        Log.e("connectWifi", "true");

        boolean enabled = mWifiManager.enableNetwork(wifiId, true);
        boolean connected = mWifiManager.reconnect();
        Log.d("connectWifi", "connectWifi:--- "+connected);
        return wifiId;
    }
