Using ContentObserver to monitor a variable change

Question

Is it possible to use a ContentObserver to monitor variable changes (e.g. String) by constructing a Uri and passing it as an argument when registering? If yes, can you provide a functional example?

Answer 1

It won't work by doing Uri.parse on an arbitrary string value.

I don't think it will work at all. What's the use case? It suggests that something outside of your control is modifying a variable. How can this happen?

Answer 2

It should work with string value,

It works with me. I have used Uri.parse like below:

contentResolver.notifyChange(Uri.parse("content://com.example.provider/notification"), null)
