WifiManager重新连接返回true但不连接

Question

如果信号足够强,我的应用会创建一个adhoc连接.不幸的是,Android不允许多个WIFI网络,所以我必须断开当前的网络.当信号变弱时,我想重新连接到前一个.

我将以前连接的SSID存储在SharedPreference中,然后使用以下代码:

 for (WifiConfiguration i : list) {
    if (i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
         wifiManager.disconnect();
         wifiManager.enableNetwork(i.networkId, true);
         boolean success = wifiManager.reconnect();
         if (!success) {
            wifiManager.reassociate();
         }
    }
 }

代码正在运行并WifiManger.reconnect();返回true但我没有连接到以前的网络.

这是我要重新连接的家庭网络的配置:

错误在于引号，因为我已经将 WifiConfiguration.SSID 存储在 SharedPreferences 中，这导致双引号 -> ""WLAN.Tele2.net""

equals("\"" + networkSSID + "\"")
