将ACCOUNT_TYPE_LOCAL添加到Android 4的日历会使其日历崩溃

作者:互联网

我想在Android中添加一个未同步的新日历.我编写了一个使用API​​级别14的新CalendarContract API执行此操作的应用程序.以下代码工作正常.我可以在Android的日历应用中看到新日历,并为其添加活动.

问题是当我选择时,Android日历应用程序崩溃:菜单 – >要显示的日历 – >要同步的日历

我的代码中有什么问题或是Android日历中的错误吗?

请注意,我不想实际使用同步适配器. CalendarContract.Calendars的文档说不需要这样做:“如果需要本地日历,应用程序可以通过插入同步适配器并使用ACCOUNT_TYPE ACCOUNT_TYPE_LOCAL来实现.”我知道“作为同步适配器插入”意味着将(CalendarContract.CALLER_IS_SYNCADAPTER,“true”)附加到URI.

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);
}

}

以下是导致日历应用崩溃的异常堆栈跟踪:

解决方法:

这是一个Android错误,显然将被修复:http://code.google.com/p/android/issues/detail?id=27474
