Suprisingly very small change was needed to disable internet connection.
In file app/src/main/java/sk/kottman/androlua//Lua.java

-			L = newState(true);
+			L = newState(false);

And some minor changes for this to work without app to throw exeption
after app close.

Or you can remove whole function
private class ServerThread extends Thread {}
class and also 3 mentions of serverThread variable. I belive I prefer
this way more.

Here folow the whole patch (made against Steve Donovan repository
https://github.com/stevedonovan/AndroLua) of the first method:

Do not accept internet connection to connect to lua
