Running Android Studio 2.1.2, Windows 7.
I replaced a ScrollView with a NestedScrollView and now I'm getting
android.view.InflateException: Binary XML file line #2: Error inflating class NestedScrollView
java.lang.ClassNotFoundException: Didn't find class "android.view.NestedScrollView" on path: /data/app/com.assemblyguide.remote-48.apk
... when I call SetContentView() on that XML file. I did not get it when I had just a ScrollView.
I've tried cleaning, and invalidating the cache and rebuilding. The XML looks like this . . .

What does this error mean and how do I fix it?

The full class name is android.support.v4.widget.NestedScrollView. Replace the <NestedScrollView> element with <android.support.v4.widget.NestedScrollView> and it should work fine. Make sure you have the v4 support library in your build.gradle file, too.
158
If using androidx, replace <NestedScrollView> or full class name <android.support.v4.widget.NestedScrollView>with <androidx.core.widget.NestedScrollView>
28
Change it to
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
