Detect Internet Connection in Android Application?

I have following method, which will check for the Internet connection in the device : 

public static boolean checkInternetConnection(Context context) {
    ConnectivityManager connectivityManager = 
            (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

    if (connectivityManager.getActiveNetworkInfo() != null
            && connectivityManager.getActiveNetworkInfo().isAvailable()
            && connectivityManager.getActiveNetworkInfo().isConnected()) {
        return true;
    } else {
        return false;
    }

}

But after a while I found out that this method only checks for the Network Connectivity; like the device is connected to a router and the router is ON but no internet is available, this method returns true.

So How to know that there is actual internet or not ?

So what is 'actual internet'? The ability to connect to any possible host on the Internet at any given time? A bit hard to test, no? Try connecting to a well-known server (Google, NASA, your country's top provider home page), and if it works, you probably have 'actual Internet'.

The only way I see for you is trying to connect to a website like google and if you get result then you can be sure of it, else no internet activity.

try this function...

public static Boolean checknetwork(Context mContext) 
    {

        NetworkInfo info = ((ConnectivityManager) mContext
                .getSystemService(Context.CONNECTIVITY_SERVICE))
                .getActiveNetworkInfo();
        if (info == null || !info.isConnected()) 
        {

            return false;
        }
        if (info.isRoaming()) 
        {
            // here is the roaming option you can change it if you want to
            // disable internet while roaming, just return false
            return true;
        }

        return true;

    }
