Answer 1

//This timer will show min:sec format and can be paused and resumed

public class YourClass extends Activity{
TextView timer;
CountDownTimer ct;
long c = 150000; // 2min:30sec Timer
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.YourXmlLayout);
    timer = (TextView)findViewById(R.id.Yourtimer)
    startTimer(); // it will start the timer

}

public void startTimer(){
ct = new CountDownTimer(c,1000) {
    @Override
    public void onTick(long millisUntilFinished) {
    // Code to show the timer in min:sec form
    // Here timer is a TextView so
    timer.setText(""+String.format("%02d:%02d",millisUntilFinished/60000,(millisUntilFinished/1000)%60));
    c = millisUntilFinished; // it will store millisLeft
    }

    @Override
    public void onFinish() {
        //your code here

    }
};
ct.start();

}
/*===========================================================
*after creating this you can pause this by typing ct.cancel()
*and resume by typing startTimer()*/
