这是我的布局

<de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/upDP"
    android:layout_width="180dp"
    android:layout_height="180dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="24dp"
    android:layout_marginEnd="8dp"
    android:src="@drawable/ic_man"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.496"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

我已经阅读了该错误（java.lang.ClassNotFoundException：找不到class）与某些Multidex相关。但是我没有用。请帮助我。

我已经完成了清理项目的所有工作。使缓存无效。删除构建文件夹等。什么都没有。

按照此处的确切步骤操作：https://github.com/hdodenhof/CircleImageView 图书馆只能在我的一个旧应用中使用，而不能在该应用中使用
