ACCOUNT_TYPE_LOCAL이 (가) 캘린더를 Android 4에 추가하면 캘린더가 손상됩니다.

Question

Android에 동기화되지 않는 새 캘린더를 추가하고 싶습니다. API 레벨 14에서 새 CalendarContract API를 사용하여이 작업을 수행하는 응용 프로그램을 작성했습니다. 다음 코드는 정상적으로 작동합니다. Android 캘린더 앱에서 새 캘린더를보고 이벤트를 추가 할 수 있습니다. - 달력이 표시> -> 달력 동기화 내 코드에 뭔가 문제가

가 아니면 안드로이드 달력의 버그 메뉴 :

문제는 안드로이드 캘린더 응용 프로그램 충돌은 내가 선택할 때이다?

실제로 동기화 어댑터를 사용하고 싶지는 않습니다. CalendarContract.Calendars의 문서에는 이것이 필요하지 않다고 나와 있습니다 : "로컬 캘린더가 필요한 경우 앱은 동기화 어댑터로 삽입하고 ACCOUNT_TYPE 중 ACCOUNT_TYPE_LOCAL을 사용하여 앱을 실행할 수 있습니다." "동기화 어댑터로 삽입"은 (CalendarContract.CALLER_IS_SYNCADAPTER, "true") URI에 추가한다는 의미입니다.

이 안드로이드 버그 분명히 해결 될 것입니다 : http://code.google.com/p/android/issues/detail?id=27474

다음

public class CalendarMapper { 

private static final String ACCOUNT_NAME = "private"; 
private static final String INT_NAME_PREFIX = "priv"; 

private static Uri buildCalUri() { 
    return CalendarContract.Calendars.CONTENT_URI 
      .buildUpon() 
      .appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true") 
      .appendQueryParameter(Calendars.ACCOUNT_NAME, ACCOUNT_NAME) 
      .appendQueryParameter(Calendars.ACCOUNT_TYPE, CalendarContract.ACCOUNT_TYPE_LOCAL) 
      .build(); 
} 

private static ContentValues buildContentValues(Calendar calendar) { 
    String dispName = calendar.getName(); //Calendar.getName() returns a String 
    String intName = INT_NAME_PREFIX + dispName; 
    final ContentValues cv = new ContentValues(); 
    cv.put(Calendars.ACCOUNT_NAME, ACCOUNT_NAME); 
    cv.put(Calendars.ACCOUNT_TYPE, CalendarContract.ACCOUNT_TYPE_LOCAL); 
    cv.put(Calendars.NAME, intName); 
    cv.put(Calendars.CALENDAR_DISPLAY_NAME, dispName); 
    cv.put(Calendars.CALENDAR_COLOR, calendar.getColor()); //Calendar.getColor() returns int 
    cv.put(Calendars.CALENDAR_ACCESS_LEVEL, Calendars.CAL_ACCESS_OWNER); 
    cv.put(Calendars.OWNER_ACCOUNT, ACCOUNT_NAME); 
    cv.put(Calendars.VISIBLE, 1); 
    cv.put(Calendars.SYNC_EVENTS, 1); 
    return cv; 
} 

public static void addCalendar(Calendar calendar, ContentResolver cr) { 
    if (calendar == null) 
     throw new IllegalArgumentException(); 

    final ContentValues cv = buildContentValues(calendar); 

    Uri calUri = buildCalUri(); 
    cr.insert(calUri, cv); 
} 

} 

는 충돌에 달력 응용 프로그램을 일으키는 원인이되는 예외의 스택 추적입니다
