Continues Internet Connection Checking in Android App [Checking Availability of Internet]

Question

Before answer or taking any action just by seeing the question title please read description carefully, I am trying to do this yesterday and today a full day and night but I couldn't find any acceptable solution. Some are deprecated from android some are not working, some are just checking internet is just connected or not . But that's not what I am asking for.

I have applied many Stack Overflow answers in this regard but nothing is working perfectly. The functionality I am asking for is, say MathActivity.java and activity_math.xml is a page loaded after clicking a button from mainActivity.java . When MathActivity.java is starting after clicking the button its primarily can check active internet connection via the ping method. Though its not working properly,

public boolean checkIntCON() {
        try {
            Process ipProcess = Runtime.getRuntime().exec("/system/bin/ping -c 1 8.8.8.8");
            return (ipProcess.waitFor() == 0);
        }
        catch (IOException e)          { e.printStackTrace(); }
        catch (InterruptedException e) { e.printStackTrace(); }
        return false;
    }

But its check just one time when I am entering [I did that work but I don't want that] , say user is reading a pdf in activity_math.xml and when user reading this user turned off internet connection, I am also able to listen that functionality when user turn off connection this would be ok but if user again turn on data with internet unavailability then I can't listen this .

I want to get recent and maximum device supported solution to check in continues internet connection. say user is reading a pdf, after five minutes I want to check if the user have an active internet connection or not. Connection should be must transferrable internet connection. I have found AsyncTask solution but its deprecated. The main focus is I want to check user active internet connection after a certain interval.

Here is an image to explain more,

Is there any solution? If any please try to give me in detail code that i just want to copy and paste in project. I have visited all in stack overflow again I am mentioning.

Pass context and call the function, I think this is what you are looking for.

 public static boolean isConnected(Context context) {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            NetworkCapabilities capabilities = connectivityManager.getNetworkCapabilities(connectivityManager.getActiveNetwork());
            Log.d("VIP", "isConnected: " + capabilities.getTransportInfo() + " down stream " + capabilities.getLinkDownstreamBandwidthKbps() +
                    " up stream " + capabilities.getLinkUpstreamBandwidthKbps() + " Cellular " + capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)
                    + " WiFi " + capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) + " Ethernet " + capabilities.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET));
            return capabilities != null && capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) || capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) || capabilities.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET);
        } else {
            NetworkInfo networkInfo = Objects.requireNonNull(connectivityManager).getActiveNetworkInfo();
            boolean b = networkInfo != null && networkInfo.isConnected() && networkInfo.getDetailedState() != NetworkInfo.DetailedState.VERIFYING_POOR_LINK;
            Log.d("VIP", "isConnected: else is connected " + b);
            return b;
        }
    }
