TAG is causing an error

When I type TAG within the parenthesis of Log.d(), TAG shows up in red and when I hover over it with the mouse, it says "'TAG' has private access in 'android.support.v4.app.FragmentActivity'". I am not sure what that means. Please help!

you are missing the line of code that sets the tag variable. also looking at the video your class has the wrong super class. It should inherit from Activity not ActionBarActivity so you will need to change that (the part that comes after extends)

//change the super class to Activity
public class StoryActivity extends Activity {

    //add the tag 
    public static final String TAG = StoryActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_story);

        Intent intent = getIntent();
        String name = intent.getStringExtra("name");

        if(name == null) {
            name = "Friend";
        }
        Log.d(TAG, name);
    }
}

Can you help me with my code:

import android.app.Activity; import android.content.Intent; import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem;

public class StoryActivity extends Activity {

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

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_story);
}
Intent intent = getIntent();
String name = intent.getStringExtra("name");

if(name == null){
    name == "Friend";
}
Log.d(TAG, name);

}

I checked it line by line and it's identical. Also tried deleting and retyping, nothing works: if(name == null){ --- if unexpected token; name unknown class name, == name unepected token; name == "Friend"; } --- all not a statement Log.d(TAG, name); d can not resolve symbol, TAG, name unknown class name

I have substituted everything with you code - errors go away. So, I am just woundering here what is wrong?

package com.example.user.interactivestory;

 import . . .

public class StoryActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_story);

    Intent intent = getIntent();
    String name = intent.getStringExtra("name");

    if(name == null) {
        name = "Friend";
    }
    Log.d(TAG, name);
}

}

This is my code for StoryActivity.java
