A resource defined like so:
<item type="drawable" name="foo" />
should be assigned the value @null.
The only exception is for <string> resources, which are given the
empty string value (since <string></string> is ambiguous). The decision
to use "" is based off the fact that old AAPT used to assign "" to all
undefined resources, even non-string ones.
