Android Build a Simple Android App with Kotlin Testing and Debugging Writing to the Log

Use a method to set the TAG variable instead of hard-coding the class name as "TreehouseActivity".

I don't know where i am getting it wrong

import android.app.Activity
import android.os.Bundle

class TreehouseActivity : Activity() {
  val TAG = TreehouseActivity.class.getName()

  override fun onCreate(savedInstanceState: Bundle) {
    Log.d(TAG, "Activity created!")

I think the method you need to call is getSimpleName(). Plus remember you're working with Kotlin in this project, so the syntax to call the method will be slightly different.

private val TAG = TreehouseActivity.class.java.getSimpleName

thank you i used val TAG = TreehouseActivity::class.java.simpleName
