WifiConfiguration enable network in Lollipop

Question

I was working on Wifi project, there is a module that enable user to join wifi programatically.

In kitkat and below it's working successfully, but in Lollipop it's not working.

Here is the code :

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.SSID = "\"testSSID\"";
wifiConfiguration.hiddenSSID = true;
wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
wifiConfiguration.allowedKeyManagement
.set(WifiConfiguration.KeyMgmt.NONE);
netId = wifiManager.addNetwork(wifiConfiguration);
Log.d("WifiPreference", "add Network returned " + netId);
boolean checkEnableWifi = wifiManager.enableNetwork(netId, true);
Log.d("WifiPreference", "enableNetwork returned " + checkEnableWifi);

my tested device is nexus 5 build number LRX21O, is ther something wrong in my code or bug on Lollipop?

Faced similar issue on lollipop.

Disabling other networks manually, an then reconnecting wifi manager solved the issue.

boolean enableNework(String ssid, Context cxt) {
    boolean state = false;
    WifiManager wm = (WifiManager) cxt.getSystemService(Context.WIFI_SERVICE);
    if (wm.setWifiEnabled(true)) {
        List<WifiConfiguration> networks = wm.getConfiguredNetworks();
        Iterator<WifiConfiguration> iterator = networks.iterator();
        while (iterator.hasNext()) {
            WifiConfiguration wifiConfig = iterator.next();
            if (wifiConfig.SSID.equals(ssid))
                state = wm.enableNetwork(wifiConfig.networkId, true);
            else
                wm.disableNetwork(wifiConfig.networkId);
        }
        wm.reconnect();
    }
    return state;
}
