[...] 获取 Google Calendar 的数据不像获取联系人和短信等数据那样，官方有文档，而这是官方不支持的。于是我就在网上查了很久，最后终于查到一个比较靠谱的，http://jimblackler.net/blog/?p=151，这网页上面写得很清楚，我就不粘贴代码了，唯一注意的是一定要添加android.permission.READ_CALENDAR 在 AndroidManifest.xml 里。不过想起来，有的日程事件不是上课，就没有必要设默认静音。然后我就想到 Google Calendar 在新建每个 event 的时候，都会有两个选择，Busy 和 Available。如果选Busy 的时候，就表示你很忙，需要静音，选 Available 的时候，就表示不需要静音，这样岂不是很好？但是，这个 Busy 和 Available 具体又对应 Google Calendar 的数据库的哪个字段呢？然后我看了看 android.provider 里面的 Calendar.java 源码，源码里面有一个字段的注释让我觉得有点靠谱，“transparency”，注释是：Transparency for the event– does the event consume time on the calendar?，嗯，就是它了。后来我有点不确定，自己实际试了试，新建两个 event，一个选 Busy，一个选Available，然后用 Root Explorer 实际看这两个 event 的 transparency 字段值，发现就是这个字段。OK！ [...]

I was wondering if you have a comprehensive example to use the new API for ICS along with for 3.x and below without having to recompile for each type of device.

Time for an update - they finally released the public API, and it's slightly different. In ICS there is a new CalendarContract class, similar to what they did for ContactContract. See the official docs for the names you should now use instead of hardcoding strings that happen to work... See http://developer.android.com/reference/android/provider/CalendarContract.Calendars.html for the real deal.

Thanks for above info. I have a doubt, in my app, i need to show only todays/current days’ events.How do i specify the range for that ?

Also, if i need 2 show events for today & tomorrow, how can i do that ? Do i need to use a different URI :- “/instances/when” OR “/instances/whenbyday” ?
Pl help

Hello Jim,
I was wondering whether you was also experiencing weird issues with Google Calendar:
while using your example my “all day” events start at 01am and finish at 01am the next day.
However the time of “startTime-endTime” events is correct.
Have you experienced this behaviour?

Hi Jim,
I have followed your tutorial to access the internal android calendar database. It works for all entries except for recurring events. The cursor does not return any recurring events at all. Can you please help me here. I am running this on Froyo (2.2) Following is my cursor declaration –

String[] projection = new String[] { “title”, “description”, “dtstart”, “eventLocation” };
String selection = “(calendar_id=” + calID + “)AND ” + (now – window)
+ “ String sortorder = "dtstart ASC";

Cursor managedCursor = getCalendarManagedCursor(projection, selection,
"events", sortorder);

private Cursor getCalendarManagedCursor(String[] projection,
String selection, String path, String sort) {
Uri calendars = Uri.parse("content://calendar/" + path);
Cursor managedCursor = null;
try {
managedCursor = getContentResolver().query(calendars, projection,
selection, null, sort);
} catch (IllegalArgumentException e) {
Log.w(DEBUG_TAG,
"Failed to get provider at [" + calendars.toString() + "]");
}

if (managedCursor == null) {
// try again
calendars = Uri.parse("content://com.android.calendar/" + path);
try {
managedCursor = getContentResolver().query(calendars,
projection, selection, null, sort);
} catch (IllegalArgumentException e) {
Log.w(DEBUG_TAG,
"Failed to get provider at [" + calendars.toString()
+ "]");
}

@Bmjones:
you said that you can run it on android 2.3. I can’t in my Samsung Galaxy S2 (That is 2.3.3).
This is the code I use:

Cursor cursor = getContentResolver().query(Uri.parse
(“content://com.android.calendar/calendars”),
new String[]{“calendar_id”,”displayname”},null,null,null);

is it correct ??
“content://com.android.calendar/calendars” is good for 2.3 ??
thank you for help !!
