#31230 — Toasts on Android?

Hello clf,

I'm stumped.  I thought it would be a convenient thing to put out some
android Toasts for debugging purposes, but I've had to write to a file
instead.

I'd gotten this far:

  require jni-helper.fs
  also jni

  jni-class: android/widget/Toast
  jni-static: Toast.makeText makeText (Landroid/content/Context;Ljava/lang/CharSequence;I)Landroid/widget/Toast;
  jni-method: Toast.show show ()V

  : toast ( c-addr u -- )
    cstring $0! make-jstring  \ js"
    clazz swap 0 Toast.makeText >o Toast.show o> ;

But TOAST throws a Java exception at Toast.makeText .  I don't know the
Java exception it throws - it seems that the message should be printed
to gfortherr.log, but it doesn't make it.  I assume that Toast.makeText
is either unhappy with its arguments or is unhappy with the thread that
it's running under.  I've exhausted alternative arguments; I don't know
how to give it other threads to run with.

Here's a word that more readily fails where TOAST does:
  
  : toasty clazz js" eureka" 0 Toast.makeText ;

Has anyone toasts to work under gforth on Android?

It's not a pressing matter for me.  Just something I expected to be
easy, that wasn't.

I suppose it doesn't like the thread you are calling it from.  I didn't have 
success with the unpacking spinner from the Gforth task either, so the 
spinner now posts a message to the original Java task, which then creates 
the spinner widget.
