I need to study the programming architecture of different smartphone OS and recommend some upgrades.
A small file sharing app (to send a file from a computer to the mobile device and from a mobile to a computer over wifi) for both android and blackberry has to be developed in Eclipse and can be demonstrated using the emulators. Have to show the difference in writing the code for these two different OS. You need to explain me how to write this code. Provide the documentation part which shows the differences in these two OS. Explain how these 2 OS are different than iOS (iPhone operating system).
What are the differences between the 3 OSs (Android, Blackberry and Iphone iOS). What can be done to improve them. What not to be done while writing the codes.
