Enable or Disable Connection

private void showConnectionDialog() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {


            startActivityIfNeeded(new Intent(android.provider.Settings.Panel.ACTION_INTERNET_CONNECTIVITY), 1002);

        } else {

            startActivityIfNeeded(new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS), 1002);

        }

    }

    private boolean isNetworkAvailable() {
        android.net.ConnectivityManager connectivityManager = (android.net.ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnected();

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1002) {

            if(isNetworkAvailable()) {

                //use Timer because network need some time for connect successfully

                TimerTask t  =new TimerTask() {
                    @Override
                    public void run() {
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                Toast.makeText(getApplicationContext(), "Connection Successful", Toast.LENGTH_SHORT).show();

                            }
                        });
                    }
                };

                Timer _t = new Timer();
                _t.schedule(t, 1000);



            } else {

                Toast.makeText(getApplicationContext(), "Not Connected", Toast.LENGTH_SHORT).show();

            }
