定时器任务在android中无限期后停止运行

public void onStart(Intent intent,int startid) {
    //this is the code for my onStart in service class
    int delay = 1000; // delay for 1 sec.

    final int period = 5000; // repeat 5 sec.

    timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
                        executeCode();
    },delay,period);

};
