    @Override

        super.onCreate(savedInstanceState);

        Intent intent = getIntent(); //this will return the intent that started this activity.
        String name = intent.getStringExtra("name"[1]); //intent.getStringExtra(key) //put "String name = " in front to store it in a String variable.
    Log.d(TAG, name);

    // So the first thing we can do to avoid a hard crash (from confusing "name"[1] with "Name") is add a null check around this
    // call to get string extra.
    // This is a good practice to do whenever we're getting data from an intent:
    if (name == null) {
       name = "Friend"; // now no matter what when we call this log statement our name variable will have a value.
    }
