Android check whether internet connection is available or not

Android check Internet Connection:

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

if (connectivityManager != null) {
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();

    if (activeNetworkInfo != null) { // connected to the internet
        // connected to the mobile provider's data plan
        if (activeNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
            //  Wifi Is Enable
            return true;
        } else return activeNetworkInfo.getType() == ConnectivityManager.TYPE_MOBILE; // Is Mobile Network Available?
    }
}
