Capture the countdown timer in different activities

I´am designing a countdown timer, that works perfectly but only If I stay in this Activity. Because, if the countdown starts and I go back for example and start other Activity, the countdonws follows counting down. And logically if I start again the activty where the countdown timer is, it appears like nothing is counting down, but in the bacground is counting down, I know because on the ontick of the timer, I throw a continue notification to show it at the notification tab.

The code is bellow, sendnotification method is a method that throws a alert when the time finishes, and the sendnotificationTiempo to send a notification to the tab every second to show at the top.

public static final int NOTIFICATION_ID = 33;
public static final int NOTIFICATION_ID_Tiempo = 34;
private int minCrono;
TextView text;
MyCounter timer;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    StartCrono = (Button) findViewById(R.id.butt_start);
    CancelCrono = (Button) findViewById(R.id.butt_cancel);
    text=(TextView)findViewById(R.id.text_countTime1);

    CancelCrono.setEnabled(false);


    minCrono = mins.getCurrentItem();

    StartCrono.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            minCrono=(60000*minCrono);      
            timer = new MyCounter(minCrono,1000);
            timer.start();
        }
    });

    CancelCrono.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            timer.cancel();     
            text.setText("El tiempo se ha cancelado");
            minutosCrono =  mins.getCurrentItem();

            if (mNotificationManager != null)
                mNotificationManager.cancel(NOTIFICATION_ID_Tiempo);

        }           
    });
}

Countdown Class:

public class MyCounter extends CountDownTimer{          
    public MyCounter(long millisInFuture, long countDownInterval) {     
        super(millisInFuture, countDownInterval);           
    }
     @Override
    public void onFinish() {

        StartCrono.setEnabled(true);
        CancelCrono.setEnabled(false);
        mins.setEnabled(true);
        minCrono = mins.getCurrentItem(); 
        // 

        text.setText("Time Complete!"); 

        sendnotification("Guau", "Time finished.");

    }
    @Override
     public void onTick(long millisUntilFinished) {
        long segRestantesTotal=(millisUntilFinished/1000);
        long minRestantes= (segRestantesTotal/60);
        long segRestantes= (segRestantesTotal%60);


        if(segRestantes>=10){
            text.setText(minRestantes+":"+segRestantes);
            sendnotificationTiempo("Guau", minRestantes+":"+segRestantes);
        }
        else{
            text.setText(minRestantes+":0"+segRestantes);
            sendnotificationTiempo("Guau", minRestantes+":0"+segRestantes);
        }
    }   
}

}

So what I would to do, is to know when I go back the Activity and I start another one, to show the time what is counting down at the background to show it for example in a textview.

Or maybe if I can get the time that is counting down from the notification tab perfect. Thanks!

Move your MyCounter instance out of the Activity. When the Activity restarts, the instance is being recreated so the old one is gone. There are a couple ways you can do this, but you need to have your MyCounter instance live somewhere that the Activity can access it but isn't responsible for its life cycle. I use a rudimentary ServiceLocator implementation that I wrote, but you can easily create a custom Application class and keep the timer (or a controller class that creates and controls the timer) there.
