for anybody who wants to experiment:

a simple way to use nitdroid binaries (kind of):

* fetch a copy of nitdroid, unpack it on your n9
* setup an android build environment (preferably matching the nitdroid version)
* cd into the folder where the android source code is of the binary you want to use
* rename the "main" function to something else (eg. app_process_main)
* setup a makefile to compile the project into a so library
* then you can load that library using android_dlopen inside an harmattan application and load the renamed "main" function using android_dlsym, also change the android linker you're using to find the libraries inside your nitdroid environment, so that the project you're trying to use gets properly linked against it's dependencies

EDIT: the reason you need to rename the main function is that gcc treats functions differently if they are named main.

i hope this is helpful
