Hi, I have been attempting to do the following assignment and figured out how to do #2. Can you please explain to me how to do #1 and #3? I feel like I am missing something fundamental (my attempt below)

In Android Studio (using Kotlin) make an app that does the following:

1. Make the background change to a random color on a button click

2. Make the button show how many times it's been clicked with every click

3. show the time of the last time the button was clicked

Activity_main.xml

MainActivity.kt

package com.example.inclassassignment1 import androidx.appcompat.app.AppCompatActivity import android.os.Bundle import android.os.SystemClock import android.text.Layout import android.view.View import android.widget.Button import android.widget.CalendarView import android.widget.TextView import androidx.constraintlayout.widget.ConstraintSet import java.lang.Thread.sleep import java.util.* import kotlin.random.Random class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) var randomColor: Int = Random.nextInt(0, 16777215) //rgb color amount 16777215 var randomColorHex = java.lang.Integer.toHexString(randomColor) var clickerCount = 0; var timer = 0 var buttonChange = findViewById
