CodePudding user response：

As per the exception, the error is occuring for following code:

        <com.google.android.material.navigation.NavigationView
            android:id="@ id/nav_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            app:headerLayout="@layout/nav_header"
            app:menu="@menu/nav_header_menu" />

Here, @layout/nav_header is either not present in your code base or it is present in different folder or module, which is causing the issue. Since the error is caused by
