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(getString(R.string.key_name));

    if (name == null) {
       name = "Friend";

Hello,

Your IDE (I'm assuming Android Studio) is just letting you know that you assign the value "Friend" to the variable name, but you don't use it anywhere... you aren't setting it in a TextView, using it in a method, etc. This is not an error. It's just a nice little message to let you know that you have a variable that you are not yet using. Later on when you do something with the 'name' variable, that message will go away.

As a side note in your Log statement.. it should be:

Log.d(TAG, name);
