Android: Align Parent Bottom + Bottom margin

Question

I've used a relative layout and I want to set the button at bottom of the screen, However this puts it all the down to the bottom and I would like to have some margin so it there's some space between the end of the screen/view and the button. However whatever I do the button margin just doesn't do anything on 2.1+ for some reason. The relative layout contains a background so I cant but the margin on that.

Anyone know a fix for this?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="0dp"
android:background="@drawable/background" >

    <Button
        android:id="@+id/confirm_mobile_button_next"
        android:layout_width="fill_parent"
        android:layout_height="40dip"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="false"
        android:layout_centerHorizontal="false"
        android:layout_centerInParent="false"
        android:layout_margin="15dp"
        android:background="@drawable/button_shape_selector"
        android:paddingLeft="10dip"
        android:paddingRight="10dip"
        android:text="@string/confirm_mobile_no_continue"
        android:textColor="@color/white"
        android:textStyle="bold" />

</RelativeLayout>

You can simply add a padding to the RelativeLayout instead of a margin to the Button, e.g. android:paddingBottom="15dp".

In general I'm always testing my layout in the Exclipse preview using API Level 8 setting. This gives quite accurate results for most devices, including ICS and JB.
