android - CountDownTimer strange behaviour -

hello , in advance!,

i've got countdowntimer want make pause while show increasing count 1 given number, interval. thing that, code below, counter 29 28 , don't know why.

can me?.

    public void countdown(view v) {     int finishnumber = 30;      final countdowntimer countdown = new countdowntimer(finishnumber * 100, 100)     {         int numbertoshow = 1;          public void ontick(long millisuntilfinished)         {             copyrighttv.settext(string.valueof(numbertoshow++));         }          public void onfinish()         {             copyrighttv.settext(string.valueof(numbertoshow));             this.cancel();         }     }             .start(); } 

it's not such strange behaviour - take consideration first ontick(long millisuntilfinished) invoked after 100ms (that interval you've set), , not when start countdowntimer.

secondly countdowntimer not 100% precise timer, can expect "strange behaviour".

edit

if accuracy not extremely important, try increasing countdowntimer few hundreds ms, this:

  public void countdown(final textview v)   {     final int finishnumber = 30;      final countdowntimer countdown = new countdowntimer((finishnumber + 4)  * 100, 100)     {         int numbertoshow = 1;          public void ontick(long millisuntilfinished)         {             if (numbertoshow < finishnumber)                 v.settext(string.valueof(numbertoshow++));         }          public void onfinish()         {             if (numbertoshow < finishnumber)                 v.settext(string.valueof(numbertoshow));         }     }         .start(); }
