[android-developers] Re: CountDownTimer too slow ???

hello Nikolay,

I have updated my code, following your suggestion :

public List<Long> times = new ArrayList<Long>();
CountDownTimer countDown = new CountDownTimer(Integer.MAX_VALUE, 1000)
{
@Override
public void onTick(long millisUntilFinished) {
times.add(System.currentTimeMillis());
}
....
};

and after a while I display the time between two call to "onTick" with
a loop over my list :

for (int i = 1; i < times.size(); i++) {
System.out.println(times.get(i) - times.get(i - 1));
}

And I have something like this :

07-25 18:18:37.281: INFO/System.out(408): 1034
07-25 18:18:37.281: INFO/System.out(408): 1031
07-25 18:18:37.281: INFO/System.out(408): 1017
07-25 18:18:37.281: INFO/System.out(408): 1018
07-25 18:18:37.291: INFO/System.out(408): 1011
07-25 18:18:37.291: INFO/System.out(408): 1019
...

I'm not expecting the precision of an atomic clock, but the error
margin here is huge !
