问题 I'm looking for a solution to an edge case scenario where a client continually asking the server for what's new will fail. In this example, I'm not using timestamps because of another edge case problem. That's handled in this question: A Client Walks Into a Server And Asks "What's New?" – Problems With Timestamps Assume we're using sequence numbers.

问题 I'm trying to add a new calendar to my google account by using the Android Calendar Provider API. As written in the API you have to implement a SyncAdapter to create a new calendar. So, if I understand things right I "just" have to add a new entry with my syncadapter in the CalendarContract.Calendars table - but I don't know how to do this. Unfortunately I couldn't find any examples on how to create a new calendar. (And yes, a googled a lot already). I would be grateful for even a step in the

问题 I am new to Spring Security and I have added it to my project. Everything seems to work perfectly Login/Logout and even navigating across screens.

问题 I got data on a webserver which I want to download to an iOS contact list. Is it possible to programatically create an account on iOS that works like the android "sync adapter" and is not one of the default account or an LDAP/CardDAV account? Or can I have my application to periodically chech for updates on my webserver without the user having to manually start it. (i.e. running in the background and starting up automatically when the phone is restarted) 回答1: No, to both. The best you can do

问题 I am interested in developing a library that would sync a core data model across devices via the Parse mobile backend. I want to mirror the functionality that iCloud core data sync attempts to provide. Why not use iCloud or Ensembles? I am currently using iCloud core data sync in a production app and it is not working well for me.

问题 I am trying to figure out how to copy a ringtone file (.m4r) embedded in the app to iTunes when connected.
