How to 'run' a Ubuntu based executable within an Android App??

I've got the file which runs through Ubuntu.
The file is running Pastec and when the file is running it allows me to manipulate the index to add/delete/search/etc images, which is working fine.

What I need to know is how to get that file running from with the android mobile application so as when I take a picture with the app it will add to the index or search to find comparisons, along those lines.
Any help would be greatly appreciated.
