Hi Kelvin!

This is just a small syntax error. No biggie, it happens to everyone. 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="<color:#fff092b0"> <!-- this line contains the error! -->

You've got a bracket character that is out of place. Finding these kind of small typos and syntax errors is a big part of programming, and you'll get much better and faster at debugging and finding these little errors the more you code!

Just remember that each XML tag has one opening bracket (<) and one closing bracket (>). Good job asking for help!
