Android app to sync with epesiBIM CRM(repost)

The project is to create an application for the Android platform to synchronize data to be used in offline mode. Records will be synchronized with epesiBIM - open source CRM web based application available at http://www.epesibim.com. It will use Android buil-in database to store records locally. It will need to sync contacts, calendar, phone calls and tasks data with user settings (all records or favorites only). New and edited records will try to write immediately to the web application/database and if the connection is not available it will be stored for synchronization when the connection is re-established. API for epesiBIM will be provided.
