在 android < 4.0 版中为重复事件添加例外

Question

Microsoft Office Project 2007 introduces effective work weeks and calendar exceptions, where all calendar data is associated with a set of "valid from/to" dates. -- Microsoft Office Dev Center

Google also uses this feature .

Does Android Calendar (pre- ICS ) support these features too? I tried Googling, but only found incomplete posts, such as https://stackoverflow.com/questions/13633577/android-8-sdk-14-recurring-event-exception .

I learned on a separate post that the way to access the calendar was through a content provider , however I have found no working solution

(for example, I tried using "content://com.android.calendar/exception" , but it results in an exception saying that it is an unknown url).

Any help to steer me in the right direction would be extremely helpful, as I have been Googling to no avail, and this try and try again stuff is not working well.

Answer 1

No. Android Calendar exceptions are officially supported starting with ICS (API level 14):

-- Android Developer Guide

Some versions may allow you to use the Uri you discuss, since it is derived from the source code :

public static final String AUTHORITY = "com.android.calendar";
public static final Uri CONTENT_EXCEPTION_URI = Uri.parse("content://" + AUTHORITY + "/exception");

//hence, CONTENT_EXCEPTION_URI = Uri.parse("content://com.android.calendar/exception");

however since it is not officially supported, it should not be considered reliable.

Answer 2

To answer your first question, yes, older Android has ability to have exceptions to a repeating event.

Since that API was introduced in API 14, It's probably a lot different than the previous versions' code. This link has some hints on getting events from calendars on older versions.
