    Check if the CountDownTimer is Running and also if the app is running in the background.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                myButton.setText("Button clicked");
                countDownTimer = new CountDownTimer( 3000, 1000) {
                    @Override
                    public void onTick(long millisUntilFinished) {
                        //After turning the Smartphone the follow both methods do not work anymore
                        if (!runningBackground) {
                            myButton.setText("Calc: " + millisUntilFinished / 1000);
                            myTextView.setText("Calc: " + millisUntilFinished / 1000);
                        }
                    }
                    @Override
                    public void onFinish() {
                        if (!runningBackground) {
                            //Do something
                        }
                        mTextMessage.setText("DONE");
                        runningBackground = false;
                        running = false;
                    }
                };
                //timer started
                countDownTimer.start();
                running = true;
            }
        });
    }
    
    @Override
    protected void onResume() {
        super.onResume();
        runningBackground = false;
    }
    
    @Override
    protected void onPause() {
        runningBackground = true;
        super.onPause();
    }
