Courses Plus Student 20,733 PointsThat part of the challenge can be a little tricky but if you watch the video again I think you'll pick up on what onPause requires to function properly.
The answer you're looking for if you're still stuck is:
@Override
protected void onPause() {
super.onPause();
mEditor.putBoolean(KEY_CHECKBOX, mCheckBox.isChecked());
mEditor.apply();
}

Courses Plus Student 20,733 PointsThe string of question marks in your original question was located in the onPause method. I thought that part of the challenge was the only part you needed help with. The complete answer is:
You could do some research in the documentation about the "getBoolean" method needed to see why it needs the default value of false as the second parameter. Otherwise, everything else was explained in the preceding video. Hope this helps! :)
