How to know device is connected to Wifi or 3G, programatically

Question

Hi all,

How i can know device is connected to Wifi or 3G, programmatically

Thanks

Answer 1

you can use WifiManager class as mentioned here

Edit: by calling getConnectionInfo() function of WifiManager class you will get WifiInfo object

WifiInfo has function getBSSID() which gives you connected AP's name

if its null that means it is not connected to any AP via Wifi ( Wifi is not enabled )

btw while looking for more info, i found this which should answer all your questions about mobile connectivity and wifi connectivity

Answer 2

You have to check the network info e.g. like this

private boolean isOnline() {
        ConnectivityManager connectivityManager = (ConnectivityManager)
                    getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        boolean connected = networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected();
        return connected;
    }
