If you want to use the context in your Fragment what I did is this :

private val mContext by lazy {
        this@YourFragment.context
}

And then you can use mContext as a Context.

And instead of passing applicationcontextin your Activity send this instead.

val editor =PreferenceManager.getDefaultSharedPreferences(this).edit()
...

Did you call commit() method of editor?

See details: What's the difference between commit() and apply() in Shared Preference
