Detect if Android device has Internet connection

Question

I need to tell if my device has Internet connection or not. I found many answers like:

private boolean isNetworkAvailable() {
    ConnectivityManager connect         


        

Answer 1

Check wifi type in connectivity manager:

   //check network connection
    ConnectivityManager cm = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean hasNetworkConnection = activeNetwork != null && activeNetwork.isConnectedOrConnecting();
    System.out.println("Connection ? : " + hasNetworkConnection);
    //check wifi
    boolean hasWifiConnection = activeNetwork.getType() == ConnectivityManager.TYPE_WIFI;
    System.out.println("Wifi ? : " + hasWifiConnection);

Android Documentation describes 'TYPE_WIFI' as 'A WIFI data connection. Devices may support more than one.'
