So, when using @android defines this as a system variable or something android specific that it should know. That is fine when setting a color to a system color. BUT you are just changing the color of the background. When doing that. There is no need for the @android portion. 

android:background="#fff092b0"

That is how you define the color when it's not a system color. Make sense

Let me know by selecting the answer as correct or asking further questions incase I didn't explain it well enough lol.
