Kawa on Android - problems with setting text properties using "text:"

[Benny Tsai <benny dot tsai at gmail dot com>]

Hello folks,

I just recently started working with Android programming and Scheme,
and was very excited to discover Kawa Scheme, which allows me to
combine the two interests!

However, I could use some help with an issue.  When compiling (using
"ant debug") the following "Hello World" code (as described here:
http://per.bothner.com/blog/2010/AndroidHelloScheme/):

(require 'android-defs)
(activity hello
  (on-create-view
   (android.widget.TextView (this)
    text:
    "Hello, Android from Kawa Scheme!")))

... the compilation fails with the following error:

[java] c:\Android\KawaHello\src\kawa\android\hello.scm:6:5: type
constant-string is incompatible with required type int

Line 6 is where I pass in the "Hello..." string to "text:".  I've read
that "text:" directs the compiler to look for "setText" and "addText"
methods.  Looking at the TextView API, I see that there are multiple
setText() methods, the first of which is setText(int resid).  Is the
compiler matching on that, and therefore expecting an int arg instead
of a String arg to "text:"?

This is extra puzzling to me because I've read Peter Feigl's recent
messages about Kawa on Android, and his test activity code appears to
use "text:" with Strings with no problems.

Here are some information on my environment.  Please let me know if
any additional info is needed.

Windows XP (SP3)
Sun JDK 1.6.0_24
Ant 1.8.2
Kawa 1.11, source from SVN trunk, revision 6919, compiled with "ant
-Denable-android=true"
Android SDK Tools, revision 10
Android SDK Platform-tools, revision 3
SDK Platform Android 2.2, API 8, revision 2 (also tried targeting
Android 2.3.3, API 10, revision 1, same problem occurs)

respectfully,
-Benny
