Android java.lang.ClassCastException: android.view.AbsSavedState$1 cannot be cast to android.widget.CompoundButton$SavedState

Question

This symptoms are the same as here: java.lang.ClassCastException: android.view.AbsSavedState$1 cannot be cast to android.support.v7.widget.Toolbar$SavedState

But it's not the right solution. There are no files with the same name as resource ids:

Current working dir below is app/src/main/res:

git ls-files . | cut -d "/" -f 2  | sed 's/\.xml//g' > /tmp/a
cat values/ids.xml | cut -d "\"" -f 2 > /tmp/b
cat /tmp/a | while read line; do grep -w $line /tmp/b; done

This yields no results.

Also, there are no duplicate ids within values/ids.xml

cat values/ids.xml | cut -d "\"" -f 2 | sort | wc -l
96
cat values/ids.xml | cut -d "\"" -f 2 | sort | uniq | wc -l
96

The exception occurs when I restart the app via an Alarm.

    ...
    alm.set(AlarmManager.RTC, System.currentTimeMillis() + 1000,
            PendingIntent.getActivity(this, 0, new Intent(
                    this, LauncherActivity.class), 0));
    Process.killProcess(Process.myPid());
    ...

And then it crashes before LauncherActivityies onCreate:

What is causing this behavior? It happens on low memory situations and when restarting it the app in this fashion.

Also note I don't use the CompoundButton class anywhere.

git grep CompoundButton
// no results

I infact did. When manually creating a View inside a child, i called the constructor of the child with the attributeSet from the parent giving them the same ID effectively. — Gala, Sep 25 '18 at 10:33
@bhardwaj see if you pass around a AttributeSet to a child accidentally — Gala, Sep 02 '19 at 09:01

I had the same issue with the HorizontalScrollView

android.view.AbsSavedState$1 cannot be cast to android.widget.HorizontalScrollView$SavedState

And I solved it by adding unique ids to the views in the custom ViewGroup

horizontalScrollView.id = View.generateViewId()
