Checking WIFI connection

You can use the following code to check if the active network (if any - do some null checks here) is of type WIFI.

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = connManager.getActiveNetworkInfo();
if (netInfo!=null) {
    // detect type using netInfo.getType()
}

There's a TYPE_WIFI int constant in ConnectivityManager that you can use for your check. (getType returns an int to identify the network type).

More info on the Activity Manager can be found on the Android dev site.

Disabling WIFI

n order to disable the WiFi state, you have to grant the following permission in the application manifest

android.permission.CHANGE_WIFI_STATE

You can then use the WifiManager to set enable/disable the WIFI.

WifiManager wifiManager = (WifiManager)getBaseContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(false);
