This might have something to do with stripping, are you using the Pro version of Unity and stripping the byte code? I'm not sure how that works with this build strategy. I would post a question in the Unity forums.
I have only one main activity which I start the AR player. If I create the APK with Unity, the size is 9MB. If I run with Eclipse, but now the APK size is 21,90MB. Why? The StagingArea for the Libary has a size of 33,7 MB.
