Hello ;)
I've taken a bit of a hiatus, but now I'm back to playing with Kawa and
Android. I've run into a few problems...
1) Kawa seems to be compiled against 1.8, which uses
java.lang.invoke.MethodHandle a lot, which Android does not seem to
support. Is there a simple way to compile a kawa.jar against 1.6, so I
can use it for Android?
2) In the following code, I get a kawa segfault. It seems to be related
to the anonymous inner class, if I factor that out, things work fine.
(define-simple-class test (<android.app.Activity>)
((onCreate (savedInstanceState :: <android.os.Bundle>)):: void
(invoke-special <android.app.Activity> (this) 'onCreate savedInstanceState)
(let* ((self (this)))
(let* ((adpt (object (<android.widget.ArrayAdapter>)
((*init*)
(invoke-special <android.widget.ArrayAdapter> (this) '*init* self (static-field android.R$layout 'simple_list_item_1)))
((getView (position :: int) (convert-view :: android.view.View) (parent :: android.view.ViewGroup)) :: android.view.View
#!null)))
(lv (<android.widget.ListView> self adapter: adpt)))
(setContentView lv)))))
> make -k
CLASSPATH=kawa.jar:/opt/android-sdk/platforms/android-14/android.jar java kawa.repl -d bin/classes -P test. --module-static-run --warn-undefined-variable --warn-unknown-member --warn-invoke-unknown-method -C foo.scm
(compiling foo.scm to test.foo)

Is this somehow my fault, or is this a bug in the compiler?
Thanks for any help!
Greetings, Peter
