问题 The code below works fine except when calendar.MONTH set to 1 (Feb) ,and I do not know why ? Thanks.

问题 I made a mistake on testing insert Events using CalendarContract. I set my own _ID in a Events insert. values.put(Events._ID, "156498713465"); Now, all my new events are created with a bad id (for exemple -535191590). When I click to the event in the Google Calendar Application, it crash. I have the same error as this thread : Calendar corrupted in Android I tried to delete all bad events : activity.getContentResolver().delete(Events.CONTENT_URI, Events._ID + " > ? ", new String[] { "10000" }

问题 I have a CalendarView in my app, when the user selects a date by touching that date in the monthview, the correct date is selected (verified by adding debug statements in the code), but the week before is highlighted, so it looks as if the wrong date is selected. I have found a work-around: if I set 'firstDayInWeek' to 1 the problem is solved, but by default the firstDayInweek is 2 (monday), and then this problem occurs. Thank you very much!

问题 Recently I noticed strange behaviour when i tried to schedule Activities to be run in the future using AlarmManager. Look at the code below, the first activity is started in 20 seconds, while the second activity is not started in 40 seconds instead it is started only after 60 seconds. Can anyone explain why the second intent doesn't schedule the second activity to be called instead the third intent does. Does this mean that i can have only one intent for an activity in the AlarmManager. /
