Android Cardview和RecyclerView连接到Firebase的片段中的NoSuchMethodError

我正在尝试创建一个连接到firebase的事件报告应用程序，每当我在应用程序中创建事件时，它都会以Cardview和RecyclerView的形式显示在firebase数据库中。我的应用程序已经可以在Firebase中显示输出，现在我正在尝试完成CardView和RecyclerView

但是，当我现在运行应用程序时，每当我尝试单击允许我输入事件的片段时，应用程序就会崩溃并显示此错误：

java.lang.NoSuchMethodError:Lcom/google/firebase/FirebaseApp类中没有虚拟方法zzbox（）Z；或其超类（声明'com.google.firebase.FirebaseApp'出现在/data/app/com.example.samuel.a4-CppiMKcbuMktQgH7RUO1XA==/split\u lib\u dependencies\u apk.apk中）

假定的错误是我的片段中的这一行：

mDatabase = FirebaseDatabase.getInstance().getReference().child("Incidents");

请记住，这是一个片段，我看的教程是在一个普通的课堂上

这是我输入事件的片段

现在我不知道为什么logcat会在我的代码中显示这一行作为错误，因为我在另一个片段中有一行类似的代码，它工作得非常好；下面是片段：“package com.example.samuel.a4
