Check if current connection is WiFi

Home  /  android  /  connectivity

Note: requires android.Manifest.permission.ACCESS_NETWORK_STATE in the manifest.

Neither of the methods below guarantee that the device can make requests - it might be connected to a WiFi spot that is not connected to the internet, for example.

Check if device is connected (wifi or data)

public static boolean isConnected(Context context) {
    ConnectivityManager cm =
            (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    return activeNetwork != null &&
            activeNetwork.isConnectedOrConnecting();
}

Check for WiFi specifically

public static boolean isConnectedToWiFi(@NonNull Context context) {
    ConnectivityManager manager = (ConnectivityManager) context.getSystemService(
            Context.CONNECTIVITY_SERVICE);
    if (VERSION.SDK_INT >= VERSION_CODES.LOLLIPOP) {
        for (Network network : manager.getAllNetworks()) {
            final NetworkInfo info = manager.getNetworkInfo(network);
            if ((info.isConnected() || info.isConnectedOrConnecting())
                    && info.getType() == ConnectivityManager.TYPE_WIFI) {
                return true;
            }
        }
        return false;
    } else {
        NetworkInfo wifi = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
        return wifi != null && wifi.isConnected();
    }
}
