I am working on an android app which will sync contacts/sms/mms on a webserver.
Which of the web service technologies is suitable for this app and easy to parse on server side?
Is it correct to convert contacts etc to a text file before sending to the server as I may not be able to convert mms and picture messages to a text file? I want users to restore their data from the server. Will there be any problem regarding data format while downloading data to mobile?
