Here a simple clock i developed using methods used in android native DigitalClock.java and AnalogClock.Java classes.this clock supports for events that triggered for each second or minute,so you can use those events and run your code.
- StartTickPerSecond() method uses the method used in DigitalClock.java to get the tick per second.
- StartTickPerMinute() method uses the method used in AnalogClock.java to get the tick per minute
this still may require some modifications..but hope this will be something you to start with..

How to use
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.clock_list_item);
Clock c=new Clock(this);
c.AddClockTickListner(new OnClockTickListner() {
@Override
public void OnSecondTick(Time currentTime) {
Log.d("Tick Test per Second",DateFormat.format("h:mm:ss aa ", currentTime.toMillis(true)).toString());
}
@Override
public void OnMinuteTick(Time currentTime) {
Log.d("Tick Test per Minute",DateFormat.format("h:mm aa", currentTime.toMillis(true)).toString());
}
});
}
}
