For devices with API 23+ you can check flag NET_CAPABILITY_VALIDATED

@RequiresApi(api = Build.VERSION_CODES.M)
private static boolean hasInternetConnectionM(final Context context) {
    final ConnectivityManager connectivityManager = (ConnectivityManager)context.
            getSystemService(Context.CONNECTIVITY_SERVICE);

    final Network network = connectivityManager.getActiveNetwork();
    final NetworkCapabilities capabilities = connectivityManager
            .getNetworkCapabilities(network);

    return capabilities != null
            && capabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET) && capabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED);
}

I check it on different devices and it works right. Except Xiaomi Redmi 3S MIUI 8 - it returns NET_CAPABILITY_VALIDATED for Wi-Fi without internet access.

For API < 23 I use ping.
