Help needed: [login to view URL]: Attempt to invoke virtual method on a null object reference


I have a small and simple android application (android studio) that is working fine on older android versions. Now, I compiled it to support newer android versions. The application crashes with the following error:

[login to view URL]: Attempt to invoke virtual method 'void [login to view URL]([login to view URL]$OnCheckedChangeListener)' on a null object reference.

As I was disconnected from android development for many years, I don't have the patience for debug anymore :). I need some help. I believe the issue can be solved in few minutes by a smart developer.

Please apply only if you are 100% confident to solve this issue in a short time. Thank you for your understanding.
