Android rectangle background gradient

Question

I want to crate a background gradient that goes from the inside to outside. And at the outside it should be getting darker. Here is an image:

Can anyone give me some advice how I can create something like that? Or should I take an image for this? If yes, what's about different screen resolutions? Or about landscape / portrait modus?

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
    <gradient
        android:type="radial"
        android:startColor="#f15330"
        android:endColor="#da0000"
        android:gradientRadius="150dp"
        />
   <size android:height="400dp"
       android:width="250dp"/>
</shape>
