Connect to wifi without user interaction



WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        // setup a wifi configuration
        WifiConfiguration wc = new WifiConfiguration();
        wc.SSID = "\"YOUR_SSID\"";
        wc.preSharedKey = "\"YOUR_PASSWORD\"";
        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);
wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);        
// connect to and enable the connection
        int netId = wifiManager.addNetwork(wc);
        wifiManager.enableNetwork(netId, true);
        wifiManager.setWifiEnabled(true);



//Check whether wifi is connected


You can register a BroadcastReceiver to be notified when a WiFi connection is established (or if the connection changed).

Register the BroadcastReceiver:



IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
registerReceiver(broadcastReceiver, intentFilter);
And then in your BroadcastReceiver do something like this:

    @Override
public void onReceive(Context context, Intent intent) {
    final String action = intent.getAction();
    if (action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION)) {
        if (intent.getBooleanExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED, false)) {
            //do stuff
        } else {
            // wifi connection was lost
        }
    }
