title: Where can I get a JAR to import libcore.io?
body: <p>I want to handle an <code>GaiException</code> in my App. The debugger tells me, it lives in the libcore.io package, but importing it yields an error. I guess I need to add an additional JAR to my projct to correctly resolve this type. I've been digging a bit in my android sdk folder, but don't seem to find anything of the kind.</p>
  
  <p>Thanks for any advice.</p>
