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:background="@android:color/white" >

  <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:background="aandroid:textColor"/>

</RelativeLayout>

also you have a typo "aandroid" and instead of background on the textview you will want the text color to be white

Rahul, the directions are asking you to change the text color to white on a background that is also white.

Essentially, all you would have to do is copy-paste the "@android:color/white" attribute into the TextView like so:

android:textColor="@android:color/white"

You can put this attribute between the text & textSize attribute.

The error is stemming from setting the android:background within the TextView - this is not necessary and can be deleted.
