C# – how to set the background image xamarin Android

I want to put a simple image in the background project xamarin Android... In my project, I can see the image, but I build it. Don't display it in my application

As you can see, my background picture calls hue.jpg, which is my XML file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px"
android:background="@drawable/hue" />

So... What did I do wrong?

resolvent:

Is the resolution of the image much higher than the screen used? If so, try reducing the resolution and try again
