This seems fairly clueless to me.

Clearly an Impress remote control app will consist of mainly GUI code.
Not a whole lot of text or image processing, number crunching or other
"business logic" going on in such an app. The GUI APIs for Android and
iOS are different, and neither has C++ bindings (although the
Obejctive-C of iOS can be mixed just fine with C++ code, i.e.
"Objective-C++").

The shared code would be the communication with the LO program, and
even there the underlying platform APIs that it makes sense to use
might be quite different. (If plain Berkeley sockets is what ends up
being used, that API is of course mostly the same on both.)

Yeah, but that is true only for non-interactive code, it excludes GUI
related stuff, where to look like a "normal" Android app, one
definitely should use Java. As far as I understand, "pure" C/C++ apps
for Android are typically 3D games with (as is common for games also
on desktop platforms) homegrown GUI concepts that look and feel
different for each game family or producing company. (I put "pure" in
parens because, from following the ndk mailing list, it seems to be a
common misconception that no Java at all would be involved in such an
Android app. That is not true. There is a Dalvik virtual machine also
in such app processes, and a fair amount of Java code involved. It's
just OS-provided Java code, not from the app package.)

Anyway, I thought this mailing list was purely for the non-coding aspects?
