Description

SmoothSync for Yahoo!® Calendar syncs your Yahoo! calendars. Due to its implementation as sync adapter it integrates seamlessly with the native calendar app and widgets and operates invisible in the background.

Update:
The server issues on Yahoo!'s side are still ongoing. Please report any errors to Yahoo!. Send them emails and tweets (@YahooCare) to make them move.
Please understand that I can't do anything if the servers are not working properly.

<b>Important note for Jelly Bean users</b>: To prevent the removal of your accounts on reboot install this app:

The app is designed to be as user friendly as possible. So, just enter your account data, select your calendar and SmoothSync will keep you calendars in sync.

This app does not contain a calendar user interface, it syncs to your device's stock calendar app. To do so it will create new calendars (one for each calendar in your Yahoo! account)

Yahoo Groups calendars are currently <b>not</b> supported!

Please, if you find a bug send me an email. Without detailed error description I often can't do anything especially when I can't reproduce it.

Important! If your phone removes the accounts on reboot, move the App back from SD card to the phone. Some phones (if not all) can't handle sync adapters on SD Card properly.

Please watch out for the calendar selection field when you create a new appointment. It may default to your Google calendar instead of your Yahoo! Calendar (and the app won't sync events in the Google calendar)
