read an input file from /res/raw (as an Input Stream) - kotlin

Question

enter image description hereenter image description hereenter image description hereI'm new to programming and learning kotlin through CS 193a: Android App Development on youtube.
I know that it's a bit dated but I like the teaching style. Anyway...
To read a .txt file as an input stream, the method is resources.openRawResouce(R.raw.id) is used.
Before, I had to create the raw folder in res and then put the .txt file called grewords.txt into the raw folder.
so "resources.openRawResource(R.raw.grewords)"
However, the method does not find the grewords.txt file. What am I doing wrong? I've found similar issues on the internet, but non of the solutions have helped me. Is it just an outdated way of doing things that doesn't work anymore? Cheers!
resources.openRawResource(R.raw.grewords)

defns.removeAt(index)
myadapter.notifyDataSetChanged()

fun readDictionaryFile() {
resources.openRawResource(R.raw.grewords)
}
}
fun setupList() {
// pick a random word
val list = ArrayList<String>()
list.add("Hello")
list.add("Rob")
list.add("BoBoBo")
val rand = Random()
val index = rand.nextInt(list.size)
val word = list[index]
// pick random definitions for the word
defns.add("a greeting")
defns.add("something you say when you are done")
defns.add("a dude")
defns.add("another name for a duck")
defns.add("the President")
defns.add("nothing at all")
defns.shuffle()
myadapter = ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, defns)
binding.definitionsList.adapter = myadapter
}
}

The problem is this:
import android.R
You imported the wrong R class, the one that is built into Android. You need to import the one that matches the package name of your app.
