我在我的Android应用中集成了Firebase云消息传递服务。目前，我的应用程序扩展了Application类（名为MainApplication），并在清单应用程序标记中声明。
我已按照所有说明启用Firebase云消息传递。当我运行应用程序时，我会在堆栈跟踪下面收到

甚至没有生成令牌。但是当我从清单中的应用程序标签中删除应用程序名称属性时，即不在清单中指定我的应用程序类。上面的错误消失了，我得到了令牌。
我试过调用
FirebaseApp.initializeApp(this);
在我的应用程序类的onCreate中，但仍然收到此错误。 目前我在Firebase版本下使用，但也尝试使用早期版本，但仍然收到错误堆栈。
compile 'com.google.firebase:firebase-messaging:10.2.1'
删除扩展的Application类以使用Firebase没有意义。不确定需要做什么。
