Detect whether there is an Internet connection available on Android

I need to detect whether the Android device is connected to the Internet.

The NetworkInfo class provides a non-static method isAvailable() that sounds perfect.

Problem is that:



NetworkInfo ni = new NetworkInfo();

if (!ni.isAvailable()) {

    // do something

}

throws this error:



The constructor NetworkInfo is not visible.

Safe bet is there is another class that returns a NetworkInfo object. But I don't know which.

How to get the above snippet of code to work?
How could I have found myself the information I needed in the online documentation?
Can you suggest a better way for this type of detection?

I check for both Wi-fi and Mobile internet as follows...



private boolean haveNetworkConnection() {

    boolean haveConnectedWifi = false;

    boolean haveConnectedMobile = false;



    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo[] netInfo = cm.getAllNetworkInfo();

    for (NetworkInfo ni : netInfo) {

        if (ni.getTypeName().equalsIgnoreCase("WIFI"))

            if (ni.isConnected())

                haveConnectedWifi = true;

        if (ni.getTypeName().equalsIgnoreCase("MOBILE"))

            if (ni.isConnected())

                haveConnectedMobile = true;

    }

    return haveConnectedWifi || haveConnectedMobile;

}

Obviously, It could easily be modified to check for individual specific connection types, e.g., if your app needs the potentially higher speeds of Wi-fi to work correctly etc.
