http-launch on Android

[Lee Matthews]

I was originally trying to build the code using ndk-build and the linker was complaining that it couldn't find a few functions that are in the gio library.

So I added libgio-2.0.a as a prebuilt static library to my Android.mk build script. It then compiled ok, but I'm getting runtime errors.

When I'm in the office tomorrow, I can send a copy of my Android.mk.

How did you compile the code for Android? The problem here looks like
you have two versions of GIO in the same process.
