problem building for Android

problem building for Android

[Mateusz Czaplinski]

Hi,

I've tried to build a hello-world project for Android (API v7, i.e.
2.1), following the instructions from
https://www.gnu.org/software/kawa/Building-for-Android.html. I tried
to build Kawa from SVN sources on Windows.
After `ant -Denable-android=true`, I'm getting (among others) some
input like below:
android-classes:
     [kawa] (compiling
C:\dnload\java-etc\kawa\gnu\kawa\android\defs.scm to
gnu.kawa.android.defs)
     [kawa] C:\dnload\java-etc\kawa\gnu\kawa\android\defs.scm:2:22:

     [kawa] C:\dnload\java-etc\kawa\gnu\kawa\android\defs.scm:3:24:

     [kawa] C:\dnload\java-etc\kawa\gnu\kawa\android\defs.scm:6:28:

     [kawa] C:\dnload\java-etc\kawa\gnu\kawa\android\defs.scm:9:20:
warning - no declaration seen for android.view.View
but the jar seems to build.
I then copy the `kawa-1.14.1.jar` to my $PROJECT/libs, then in my project dir:
    ant debug
but it fails with:
scompile:
     [java] (compiling
C:\prog\bookshelf2\src\kawa\android\bookshelf.scm to
kawa.android.bookshelf)
     [java] C:\prog\bookshelf2\src\kawa\android\bookshelf.scm:4:4:

while creating JavafxObjectBuilder for ClassType
android.widget.TextView - caught java.lang.ClassNotFoundException:
gnu.kawa.android.ViewBuilder

so, I tried to change the Kawa's build.xml, like so:
Index: build.xml
===================================================================
--- build.xml   (revision 8002)

       </fileset>
     </apply>
   </target>
then again rebuilt Kawa with `ant -Denable-android=true`, now getting
more warnings:

then copied the kawa-1.14.1.jar again to my libs/, and tried building
my project again, but now again got errors, only different:

Could anybody please try to help me? I'd be very grateful for a CC to
my private/original email address, as I'm hesitant to fully subscribe
to the mailing list yet, not being sure if I'll be have use for it.

Thanks in advance

inconvenient to try it out.]

There seems to some problems in the build.xml file for ant.
Specifically, it didn't automatically set the classpath
to include the android.jar.
I just checked in to SVN an updated version of build.xml (and
build.propertied) that seems to work.

There is still a problem actually running KawaHello on the emulator.
I'll try to look at that tomorrow.

Yay, seems to build & work indeed, and on my Nook Simple Touch
sporting oldish Android 2.1!
Thanks a lot!!!
