This document discusses using the XCORE library to build an Android application with certain requirements, comparing the estimated time and cost of building it from scratch versus using XCORE. It estimates that building the required screens, feeds, and features from scratch would take around 100 hours for one developer over 2 weeks, while using XCORE could reduce that time to around 41 hours over 1 week. It then lists some key capabilities that XCORE provides out of the box, like integration with servers, offline support, error handling, and utilities, that would fulfill the requirements of 90% of projects.

- 1. XCORE - library for Android platform VLADIMIR KLYSHEVICH
- 2. Customer requirements • 5 screens(3 lists, 2 details) • 5 feeds • 2.3+ support JSON
- 3. How much will it cost? • 40 hours for components that will be used on every screen • ImageLoader • Feed parser • 2-4 hours for every screen – maximum 4*5 = 20 hours • Cache/Offline support(+12-20h) • Bugfixing 10-20h 100 hours for one developer ~13 days ~2 weeks
- 4. Maybe we can save money? ???
- 5. Sure! Lets use XCORE • 40 hours for components that will be used on every screen • ImageLoader • Feed parser • 1h - integration • 2-4 hours for every screen – maximum 4*5 = 20 hours • Cache/Offline support(+12-20h) Bugfixing 10-20h • 8h - implementation • Bugfixing 4-12h approximate 100 41 hours for one developer ~5 days ~1 week
- 6. Lets take a look on xcore capabilities
- 7. Requirements for 90% projects already solved with XCORE • integration with server(json, xml will be soon) • offline mode support(cache support) • error handling(internet connection, server unavailable, etc) • progress bar support • database support • ContentProvider support • utils classes
