How to make a CountDownTimer common to multiple activites?
<p>I have Activities A,B,C,D... I create a countdowntimer in activity A....I want to call its methods in activities  B,C,D .... how do i that...I tried making the timer variable static but it has some problems and doesn't function properly...Also its not a good programming practice..So is there any other way to do this??</p>

<pre><code>public class CountTime extends Activity {

    static MyCount count;
