To check if internet connection is available or not, you can use the below code snippet

    public static boolean hasActiveInternetConnection(Context context) {
    if (isNetworkAvailable(context)) {
        try {
            HttpURLConnection urlc = (HttpURLConnection) 
                    (new URL("http://clients3.google.com/generate_204")
                    .openConnection());
            urlc.setRequestProperty("User-Agent", "Android");
            urlc.setRequestProperty("Connection", "close");
            urlc.setConnectTimeout(1500); 
            urlc.connect();
            return (urlc.getResponseCode() == 204 && urlc.getContentLength() == 0);
        } catch (IOException e) {
            Log.e(LOG_TAG, "Error checking internet connection", e);
        }
    } else {
        Log.d(LOG_TAG, "No network available!");
    }
    return false;
}

This code snippet will also help you to identify whether you device is having internet connection even if you are connected through wifi network.

Note: make sure to call this method in background thread ,because this can take time depending on your network speed, and should not be called in Main thread
