Facebook App Events崩溃的应用程序

Question

我正在尝试使用facebook app事件进行搜索，如本文档中所述：

https://developers.facebook.com/docs/app-events/android#events

我实现了我的搜索App事件：

Bundle parameters = new Bundle();
parameters.putString(AppEventsConstants.EVENT_NAME_SEARCHED, query);
logger.logEvent(AppEventsConstants.EVENT_NAME_SEARCHED,parameters);

当我打开我的应用程序来测试并执行上面代码所在的搜索方法时，我的力量关闭会出现这些错误：
