Does Android WifiManager make phantom connection?

Question

I use WifiManager to check for a specific SSID and check for a given WPA password, but I get a weird result.

The code is as follows:

WifiConfiguration wc = new WifiConfiguration();

// init ssid and password as Strings ...
wc.SSID = "\"" + ssid + "\"";
wc2.preSharedKey  = "\"" + password + "\"";

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

int res = wifi.addNetwork(wc);
boolean b = wifi.enableNetwork(res, true);

The strange part is that enableNetwork () returns true even if the Wi-Fi network with the SSID is not on the network (?!). However, note that if the target Wi-Fi network is present and the password is correct, the code successfully connects.

Android documentation says enableNetwork () "returns true if the operation completed successfully." My questions:

1) How to enable the network if it does not already exist?

2) I initialized the WifiConfiguration parameter, wc, is it wrong?

3) Is it right to do / test a connection to a Wi-Fi network?

1) , ?

Android , enableNetwork() " true, ."

, , ... false, wifi wifi.

2) WifiConfiguration, wc, ?

3) / Wi-Fi-?

, startScan(). ( SSID).
