is the hash tag included in a hex number color code, its not working for me.

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/#fff092b0"/>

  <TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

Hi, the problem is your using @android:color/ this is looking for a system color you can delete that and just use the hex value like this android:background= "#fff092b0"

hope this helps

Its not a valid hex nber. Hex numbers are 6 characters long. You have more characters than six. I recommend you select your color in a photo editor(photoshop or paint.net or something) then get the hex number directly from that. The hex you have included will fail.
