My TimerTask not running

for some reason my timer is running only once:

Code:

int i = 0;
private void startTimer() {


    final Timer timer = new Timer();
    final TimerTask task = new TimerTask() {
        @Override
        public void run() {

            Log.d("DTAG","K1");

            if(preferences.getBoolean(IS_RUNNING_KEY, false))
            {
                Log.d("DTAG","K2");
                final int k = i++;
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        timeCounter.setText(""+k);
                        Log.d("DTAG","K: "+k);
                    }
                });
            } else {

                Log.d("DTAG","K3");
                timer.cancel();
                timer.purge();

            }
        }
    };

    timer.schedule(task, 1000);

}

That's the expected behaviour of schedule(TimerTask, long). From the documentation

Schedule a task for single execution after a specified delay.

Try using scheduleAtFixedRate instead.

timer.scheduleAtFixedRate(task, 0, 1000);
