未检测到信标，并且在检测到信标时需要有关如何启动新活动的建议

Question

我还有两天的时间来计算这个代码，所以我不得不选择在这里写一个问题，希望能得到一些答案。 我正在创建一个应该检测信标的应用程序，一旦检测到信标，就应该打开一个特定的活动。 我改编了https://altbeacon.github.io/android-beacon-library/eddystone-how-to.html的代码 我有一个eddystone信标但我在log.d中没有关于信标的信息，或者即使它扫描信标也没有。我必须提到我尝试了各种方法来完成这项工作，但我认为必须完成应用程序的压力开始转向我，我无法使其工作。 所以我的问题是：我的代码下面有什么问题，如果检测到信标，我怎样才能打开活动？谢谢
