Code Challenge: The Android Log, Part 2

Hey everybody,

I seem to be having some difficulty getting past the second question in the Android Log code challenge.

The error I am receiving: Bummer! Compilation Error! Make sure you aren't using the String "MainActivity" from Task 1, and don't forget to add '.class' before the method call.

Here is my code:

    package com.example;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends Activity {

  public static final String TAG = MainActivity.class.getSimpleName;

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

I'm using .getSimpleName because in the video says that it doesn't include the package, like the prompt is asking for.

The solution is probably right in front of me but I'm not sure what I'm doing wrong, the code is almost identical to my MainActivity.java file. Thanks! And sorry, I can't seem to get the formatting right.

So close! getSimpleName is a method call. In Java, methods always have parentheses, even if there are no parameters. So in this case, the correct syntax to call that method is getSimpleName(). Without the parenthesis the system thinks you are trying to access a variable named getSimpleName, which doesn't exist (hence the Compilation Error).

Thanks Ben! This is the first time I got stuck on the course, it's really well laid out and easy to understand. Thanks again.

Thank you for posting this question David, and thank you for the answer Ben. The "try the other one" hint wasn't quite enough for me so I was stuck at ...MainActivity.class.getName();
