Setting correct resolution for Background image
<p>I want to set a background image into my app. I tried to set my background image in my xml file with android:background(im using a relative layout) but it seems the image was scaled and doesn't appear to be correct or in its original form.</p>

<p>Let's take an example if I want to display it on a 480x800 screen and only on portrait mode. Should I also produce a background image with a resolution of 480x800?</p>

<p>Thanks</p>
