Unity app with Java android background

Unity Engine

Hello,
I need your help to resolve my problem.I 'm trying to develop an AR application with Unity on android. Because it’s impossible to access directly the android camera within Unity, I’ve ever tried some things as draw an OpenGL scene in front of an android camera preview: it’s now ok.
But using a Unity application for the scene would be more convenient for me. So i’ve configured an Eclipse Java project to integrate Unity as a library.

Yet, I don’t know in what manner a Unity app behave on the screen, but obviously it hide all (that depend of the ratio), so someone has an idea how to render the Unity app background transparent, in order to my custom Java camera preview at the back could be visible?
And also, what would be the best way to communicate datas (video buffers and processing resullts) between my Java and my Unity lib?

Thanks

The easiest way for the communication would be to just draw it into a texture that you use in the scene through basic opengl commands :slight_smile:

on mobiles thats pretty trivial
