android service绑定Activity注意

1.Activity绑定Service语句最好写在onCreat（）中，绑定后会直接调用onServiceConnected方法，可以将执行语句写在该方法中。

private ServiceConnection trackcon = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            // TODO Auto-generated method stub
            TrackBinder myBinder = (TrackBinder) service;
            trackService = myBinder.getService();
            Timer updateTimer = new Timer("trackService");
            updateTimer.scheduleAtFixedRate(new TimerTask() {
                public void run() {
                    handler.post(trackRunnable);
                }
            }, 0, 150);
        }
        @Override
        public void onServiceDisconnected(ComponentName name) {
            // TODO Auto-generated method stub
            trackService = null;
        }
    };

2.将执行语句放在onstart中时导致空指针，不知道原因……可将其放在按钮等的处理程序中。
