Create a ListView in Unity Android app: use UnityGUI or Android plugin?

Hi,

I want to implement an application that will have some Unity scenes and some Android activities. At first I tried to export my Unity project to Eclipse, but I found that I couldn't close the Unity scenes without closing the app, so I had to change my design.

Right now I was trying to create an Activity with a ListView on it. I was doing it using Unity GUI, but I found that it's far from perfect (i.e. the scroll isn't smooth at all). I've never used an Android plugin in Eclipse, and I was wondering if it was possible to import a java plugin in Unity to create my Activity.

Details of the Activity I'm creating:

-It will be opened from a Unity scene. -At start, I will download a list of data from my server. -Create a ListView using the data downloaded. -Handle clicks on the list (I will open another Unity scene when the user clicks on a list item using the row data).

What do you suggest? Should I keep using Unity GUI or is it possible to do it using an Android plugin for Unity?

Thank you!
