Connect to a specified available wifi network

From my application, I am able to switch on/off WIFI in my device and able to scan the available networks, but i am unable to connect to specified available network. This is the code I am using:

 if(wifi.getWifiState()==wifi.WIFI_STATE_DISABLED)
        { 
            wifi.setWifiEnabled(true);

        }
        if(wifi.startScan())
        {
            //ls=(ArrayAdapter<ScanResult>) wifi.getScanResults();
            ls=wifi.getScanResults();

            Log.e("",ls.get(0).toString());
            for(int i=0;i<ls.size();i++)
            {   Log.e("VALUE"," "+ls.get(i).toString());
                Log.e("",""+ls.get(i).SSID);
                if(ls.get(i).SSID.equalsIgnoreCase("SPECTRUM-GREEN"))
                {
                    Log.e("","SPectrum GREEN FOUND.....");

            try{ 
                String ssid="\""+ls.get(i).SSID+"\"";
                Log.e("SSId"," "+ssid);
                config.SSID=ssid;
            }catch(Exception e){Log.e("","Error : "+e.toString());}

            config.preSharedKey="\"password\"";
            config.status=WifiConfiguration.Status.ENABLED;

            config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); 
            config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
            config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
            config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
            config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);

            config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
            config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
            config.allowedProtocols.set(WifiConfiguration.Protocol.RSN);

            int res=wifi.addNetwork(config);
                    Log.e("ENABLE ",""+wifi.enableNetwork(res, false));

                    break;
                }
            }

Although this is an old question, in case someone comes across this, the following helped me:

void connect (String ssidName) {
    boolean result = false;
    List<WifiConfiguration> arraylist = wifiManager.getConfiguredNetworks();
    for (WifiConfiguration wifiConfiguration : arraylist) {
        String wifiConfigSSID = wifiConfiguration.SSID.replace("\"", "");
        if (wifiConfigSSID.equals(ssidName)) {
            result = wifiManager.enableNetwork(wifiConfiguration.networkId, true);
            break;
        }
    }
}

If the network is already available, then there is no need for giving the various parameters, including the password.

You have to disable other networks:

wifi.enableNetwork(res, true);

Just a comment. Are you trying to connect ad hoc? This is not possible with "normal" Android phones I read...
