The question must be broken. The challenge can't resolve "setTextColor" method.

I am trying to set the text color to Blue but I keep getting an error that the "setTextColor" method can't be resolved. I tried the same method for a text view in android studio and it worked. So my best guess id that the challenge is broken.

import android.app.Activity
import android.os.Bundle
import android.widget.TextView
import android.widget.RelativeLayout

class MealActivity : Activity() {
  override fun onCreate(savedInstanceState: Bundle) {


    val foodLabel = findViewById(R.id.foodTextView) as TextView
    val drinkLabel = findViewById(R.id.drinkTextView) as TextView
    val mealLayout = findViewById(R.id.mealLayout) as RelativeLayout
    mealLayout.backgroundColor = Color.RED

As I recall, you need to use property assignment here (see the line above it as a template/hint) instead of a setter.
