Sakai OAE Native Mobile Application - project

[kamal]

Hi,
I am an undergraduate at University of Moratuwa, Sri Lanka. I am
majoring in Electronic and Telecommunication Engineering. I am going
to start my research internship at Interactive & Digital Media
Institute (MXR Lab or Keio-NUS CUTE Ctr), National University of
Singapore from next week. The research areas are Human Computer
Interaction, Digital Media Design and Mobile Application Development.
I already have experience in J2ME Application Development. I am an
Oracle Certified Mobile Application Developer since October 2010.
Further when I had chat with MXR Lab members, they told me that I will
get experience in Android Application Development and iPhone
Application Development during my 24 week internship. My Linked in
public profile is http://www.linkedin.com/in/pkamalaruban.

I am interested in the project “Sakai OAE Native Mobile Application”.
I chose this project due to my great passion towards Mobile
Application Development. I visited the site http://sakaiproject.org/welcome-sakai-oae
and understood the functionality of Sakai OAE. Once I gone through
the project requirements it seems more familiar to me as I already
have experience with Mobile Application Development.

However I am a newbie to the Open source Development Community. So it
would be helpful if you could guide me in the correct track. I would
like to find answers for the following problems:
[1] Are we supposed to start the project from scratch? Do we have to
create new frame work or develop from an existing frame work?
[2] For this particular project what sort of APIs should I have to
follow? [Links]
[3] Developer getting started point for Sakai OAE? [Link for developer
documentation or source code]
[4] Targeted platform – Android or iPhone?
[5] Further suggestions?
