    So looking at your code:

    val InterstitialId = dataSnapshot.child("interstitial_id").value.toString()

    This line will return a string when you call the .toString method, 2 lines below you are passing this variable to a .getString and according to the documentation getString() expects an Int not a String.

    What is the problem? The IDE itself tells you, an Int was expected but you are passing a String.

    To get values ​​from resources, for example, strings, themes, etc… you need to pass an Int or id of the resource, which is obtained by doing

    R.id.your_resource
