Kotlin how to work with LiveData correctly?

Question

Android

Dear members of the forum, please tell me why the "onChanged" function is not called?


I seem to have done the subscription correctly, I update the data by calling: DataController.refresh()
The source code is here: https://github.com/genbachae/T_LiveData

You have mixed java and kotlin, try this

liveData?.observe(this, Observer<String> {
    textView.text = it
})
