I tried this, but no dice. I checked gen/kawa/android/hello/R.java and
it appears to be defined in the kawa.android.hello package:

  package kawa.android.hello;

  public final class R { ...

If I explicitely qualify the name as kawa.android.R then I get warnings
about there being no declaration of R anywhere (the same as if I omit
the package or use kawa.android.hello.R). I created a jar of R*.class
and explicitly added that file to the classpath with the full pathname
(or the dir ${out-classes}/kawa/android/hello/), but that failed to work
either.

I imagine that I am doing something wrong; my ant scompile rule is:

    <target name="scompile" depends="dirs, resource-src, aidl">
      <apply taskname="kawa" executable="java" 
	     failonerror="true" parallel="true">
	<arg value="-classpath"/> <arg path="${external-libs-folder}/kawa.jar:${android-jar}:${out-classes}"/>
	<arg value="kawa.repl"/>
	<arg value="-d"/> <arg path="${out-classes}"/>
	<arg line="-P ${application-package}. --module-static-run --warn-undefined-variable --warn-invoke-unknown-method"/>
	<arg value="-C"/>
	<fileset dir=".">
	  <include name="**/*.scm"/>
	</fileset>
      </apply>
    </target>


(basically the rule you posted in the patch to build.xml on your weblog
but with the variable names updated). 

I tarred up the project @
http://unknownlamer.org/files/temp/kawa-hello.tar.gz. Any ideas?

Semirelated, is there a way to create an anonymous class that implements
an interface? I decided to play around a bit and manually create a
layout, and wanted to set the onclick method of a button but:

(evalb:setOnClickListener
        (let ((eval-expr (lambda () (tv:setText (ed:getText)))))
          (object (android.view.View.OnClickListener)
                  ((onClick (v :: android.view.View)) :: void
                   (eval-expr)))))

fails with an invalid superclass error; if I remove the superclass then
it builds but crashes (accursed java and one method anonymous
classes...).
