Android adds an event to the system calendar

Looked for a day and a half, finally a little bit about. The following is your own understanding, the wrong place to look.

Android has a calendar function, the application can be based on a number of interfaces to develop their own functions, even the Calendar app is based on these interfaces developed, so we can use the program to write events to the system calendar, and then use the Calendar software on the phone to see the events we added. Online This information is also a lot, there are demo, but I did not find a can be run correctly, some lack of parameters, some version of the reason, more than 4.0 of the system this aspect of the change is relatively large, so can only check the data while modifying.

The general idea is to see if the system calendar has an account, and if you don't have to add one, then you can add events. There are a lot of parameters that must be filled, and what sync adapter. The save of the event is per account.

is not perfect at present, will delete all the accounts in the system calendar is deleted, please note!!!

The general framework uses: http://blog.csdn.net/Android_Tutor/article/details/6165470, thanks to the original author's sharing. In order to reflect the original author's yearning feelings, the event content remains unchanged!!

Based on this, the paper makes a complete and main comment.
