Hi Mert,
Can I CC: the libreoffice@lists.freedesktop.org list here on this one ?
it's prolly best to get wider and quicker input, perhaps you can fwd
this one there as you reply ? =)

Ah - right =) so that file lokandroid.cxx is a (somewhat out of date)
Java wrapper of the LibreOfficeKit API which you can see in C form here:
include/LibreOfficeKit/LibreOfficeKit.h

Yep - so this is not the right method =)

Hey ;-) I've hacked on and around the Android code a fair bit getting
that going ;-)

The developers list is the best place; this is a very sensible
question, and I'm excited to have you interested in working on Android -
currently almost no-one is, so there is a big opportunity there =) There
is a lot that can be done to accelerate things on Android - particularly
eg. combined tile rendering, and there are lots of hooks we've added for
'Online' that can be mirrored nicely on Android these days - so it
should be easy to improve the editing UI a lot.
Anyhow ... I think you prolly want to:
extern "C" SAL_JNI_EXPORT jint JNICALL
Java_org_libreoffice_kit_Office_saveAs
(JNIEnv* pEnv, jobject aObject, jstring sUrl, jstring sFormat,
jstring sOptions)
And pass in a file-name with a ".pdf" extension which should give you a
temporary file with a PDF in it =)
That will call to:
desktop/source/init.cxx:
static int doc_saveAs(LibreOfficeKitDocument* pThis, const char* sUrl,
const char* pFormat, const char* pFilterOptions)
Which you can read to see how it works =) Of course, in terms of a UI
to set paper size and orientation and so on - I think you'll want to use
the new UNO commands exposed for 'online' to add some options for that.
Hope that helps !
Michael.
