Creating bitmap from SVG

I have an SVG icon I want to convert into a bitmap.

Documentation makes it appear I can do something like this:

<resources>
 <bitmap id="bm_clouds" filename="svg/clouds.svg" scaleX="16" scaleY="16">
 </bitmap>
</resources>

I get no warnings that this is invalid, but attempting to build, I get java.lang.OutOfMemoryError:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
