Hi, I have developed many apps with webservices/server call as internal functionalities. Please be careful to choose your developer, as this task requires 1) Wise use of background threads so that app doesn't look slow 2) Caching is required if data is large 3) Error handling and retry the server call, if there is breakup in connection in middle of data recieving. Nothing can beat experience with same work! Regards Sandeep .

Hi, I am expert in Synchronisation process, similar to your requirements. I have developed 5-6 Android apps in parallel with iPhone development. My apps were based on SugarCRM, if you ever heard this name. This is a Customer Relationship Model, and I have extensive experience of SOAP and REST along-with XML and JSON parsing. I am very good in these fields. In this model, I use sqlite database for offline mode, and SOAP or REST for live mode. Though, in these apps, I perform sync manually which is supported in offline mode only. However for your app, I can easily write a service which will automatically perform sync process if Network is available. I am quoting 7 days for the project, while it can take upto 15 days as per your requirements. However we can discuss delivery dates at your ease. I will be looking forward to discuss with you on this and would appreciate any questions. Thank you, Regards: Rizwan
