Challenge Task 1 of 2

The current layout has black text on a white background. Let's change the text color to be white. You will need to add the android:textColor attribute, and copy/paste the Android white value from the RelativeLayout's android:background attribute.

As the instruction says, you need to add the android:textColor attribute to the TextView and set its value to: @android:color/white.
