在冰淇淋三明治中運行應用程序時發生崩潰

Question

實際上，我創建了一個應用程序，它將事件存儲在設備日曆中，並且其工作正常，並將事件存儲在設備日曆中。但是當我嘗試在ICE CREAM SANDWICH中做同樣的事情時，它會使應用程序崩潰，爲什麼會發生這種情況。任何人都可以幫我解決這個問題。我用來保存下面顯示的設備日曆中的事件的代碼，以及崩潰的日誌貓也在那裏。

代碼保存事件設備的日曆

public boolean setAlertOnDevice(Context c) 
{     
Resources res = c.getResources(); 

Uri EVENTS_URI = Uri.parse("content://com.android.calendar/" + "events"); 

Uri REMINDERS_URI = Uri.parse("content://com.android.calendar/" + "reminders"); 

    ContentResolver cr = c.getContentResolver(); 

Date dtStartDate = getStartDate(); 

Calendar cal = Calendar.getInstance(); 

cal.setTime(dtStartDate); 
cal.add(Calendar.DATE, m_iStart); 

cal.set(Calendar.HOUR_OF_DAY, 8); 
cal.set(Calendar.MINUTE, DEFAULT_TIME_OF_DATE);  
cal.set(Calendar.SECOND, DEFAULT_TIME_OF_DATE); 
cal.set(Calendar.MILLISECOND, DEFAULT_TIME_OF_DATE); 

String str = m_reminderText + res.getString(R.string.alert_start);           
m_strDescription = res.getString(R.string.alert_start_msg); 

ContentValues values = new ContentValues(); 
values.put("calendar_id", 1); 
values.put("title", str); 
values.put("description", m_strDescription);      
values.put("dtstart", cal.getTimeInMillis()); 
values.put("dtend", cal.getTimeInMillis()); 
values.put("hasAlarm", 1); 
Uri event = cr.insert(EVENTS_URI, values); 

m_calendarEvents[m_calendarEventCount] = event; 
m_calendarEventCount = m_calendarEventCount + 1; 

values = new ContentValues(); 
values.put("event_id", Long.parseLong(event.getLastPathSegment())); 
values.put("method", 1); 
values.put("minutes", 10); 
cr.insert(REMINDERS_URI, values); 
}

Answer 1

alextsc是正確的。您在這裏使用的是未公開的API，這些API是不支持的，並且因爲冰淇淋三明治而被破壞。閱讀他鏈接到的blog post，然後研究使用CalendarContract API來製作冰淇淋三明治。

Answer 2

我也遇到這個問題，現在我解決它。您想要在ICE CREAM SANDWICH之上正常工作的代碼，您需要設置eventTimezone的值。那麼，只需要添加代碼，如

ContentValues values = new ContentValues(); 
values.put("calendar_id", 1); 
values.put("title", str); 
values.put("description", m_strDescription);      
values.put("dtstart", cal.getTimeInMillis()); 
values.put("dtend", cal.getTimeInMillis()); 
values.put("hasAlarm", 1); 

values.put(Events.EVENT_TIMEZONE, TimeZone.getDefault().getID()); //add this row 

Uri event = cr.insert(EVENTS_URI, values);
