android.util.AndroidRuntimeException

错误代码是：

 07-07 08:34:19.693 11797-11809 E/JavaBinder﹕ 
 *** Uncaught remote exception! (Exceptions are not yet supported 
 across processes.)
 android.util.AndroidRuntimeException: { what=102 when=-22ms 
 obj=android.os.BinderProxy@4218d598 } This message is already in 
 use.

我现在不能很肯定是哪里的消息使用错误，请大神们帮我看看这段代码有没有错误

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_alarm);
        ctext = this;
        CfgLooper = Looper.myLooper();
        CfgHandler = new CfgHandler(CfgLooper); 
        show_alarm();
    }

  public  class CfgHandler extends Handler {
          public  CfgHandler(Looper looper) {
              super(looper);
          }
          public void handleMessage(Message msg) {
                    switch (msg.what) {
                        case comm_frame.SYS_CFG_RSP_FRM:
                            sys_cfg_rsp sys_cfg_rsp_info;
                            sys_cfg_rsp_info = (sys_cfg_rsp) msg.obj;
                            if (sys_cfg_rsp_info.child_type == comm_frame.SYS_CFG_TYPE_ALARM) {
                                new AlertDialog.Builder(ctext).setTitle("完成")
                                        .setMessage("设置成功")
                                        .setPositiveButton("确定", null).show();
                            }
                            break;
                        case comm_frame.EVENT_RSP_FRM:
                            event_info_rsp_class event_info_rsp;
                            event_info_rsp = (event_info_rsp_class) msg.obj;
                            comm_frame.invokeLongTimeToast(event_info_rsp, ctext);
                            break;
                    }
          }
     }

show_alarm()是4个check_box。
请教下是不是这段代码有错误呢？
