changing text and background color

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

activity_main.xml 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:backgroundColor="#ff51b46d">

  <TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="Treehouse loves me!"
    android:textSize="72sp" /> 
    android:textColor="white" />


</RelativeLayout>

Don't set the android:textColor property to white. He just wants you to copy/paste it from the top section as #ff51b46d. Also, if you want to use the system colors, you'll need to set it to something like: @android:color/white
