1. Application must run on different platforms


2. Difficult to reuse code

Code is specific to the:

SDK Language


How to maximize code reusability between different development platforms?


We will investigate these questions:

•What components can be reused?

•How can components be decoupled from the SDK?


1. Develop a mobile application

App should run on Android and Blackberry

App should represent most commonly used features

2. Evaluate component reusability

What components are SDK‐dependent

How can these components be decoupled from SDK?


What is our mobile application?


What is our mobile application?

A collaborative notepad for your mobile phone


Create notes

Edit notes

Save notes

Share notes

Collaborate on notes


Platform Decisions Feature Decisions


Why these platforms?


Both use Java

Both support SQLite database

Well documented SDKs

Conclusion: Easy to compare component reusability14Group G8 ‐ Aaron Jin / Jenelle Chen

Identified functional areas that are commonly used in most mobile applications

How did we pick features for ABI Notes?
