Android Build a Simple Android App (2014) Testing and Debugging Writing to the Log

Help with code challenge (Build a simple android app).

I don't know what to do, the question is:

Use a method to set the TAG variable instead of hard-coding the class name as "TreehouseActivity". We want just the class name by itself without the package name: is it getName() or getSimpleName()? Change the "TreehouseActivity" string to the correct method call (ex. TreehouseActivity.class.<insert correct method>).

com/teamtreehouse/TreehouseActivity.java
package com.teamtreehouse;

public class TreehouseActivity extends Activity {

  public static final String TAG = "TreehouseActivity";

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_treehouse);
    Log.d(TAG, "Activity Created!");
  }
}

The question is asking you to create a function (inside of a class, a function is called a 'method') to set the TAG variable to the class name.

So you could create a method called setTag() and pass the result of that into the TAG variable, like so :

public void setTag() { this.TAG = TreehouseActivity.class.getSimpleName(); }

The challenge is really not asking you to create a method to set the TAG. You just need to use an already existing method which is getSimpleName(). So try this:

public static final String TAG = TreehouseActivity.class.getSimpleName();

Aah. I see. I haven't really taken that course. Thought it the question was about creating a method. :)

Thanks!
