今天在service中写了个内部广播接收器，结果运行的时候出现下面的问题：

Process: com.lu.times.times, PID: 7551

其实很简单啦，内部的broadcastReceiver需要被动态注册，或者是static类。
这样就OK了,我比较喜欢~

 private void registerReceiver(){
        xxxReceiver = new xxxReceiver();
        IntentFilter filter = new IntentFilter();
        filter.addAction("xxxx");    
  }
