android - Is there a way to access the calendar's entries without using gdata-java-client?

Is it possible to get the calendar's entries from the phone offline? It seem the only way is to use gdata-java-client.

Josef and Isaac's solutions for accessing the calendar only work in Android 2.1 and earlier. Google have changed the base content URI in 2.2 from "content://calendar" to "content://com.android.calendar". This change means the best approach is to attempt to obtain a cursor using the old base URI, and if the returned cursor is null, then try the new base URI.

Please note that I got this approach from the open source test code that Shane Conder and Lauren Darcey provide with their Working With The Android Calendar article.

private final static String BASE_CALENDAR_URI_PRE_2_2 = "content://calendar";
private final static String BASE_CALENDAR_URI_2_2 = "content://com.android.calendar";
/*
 * Determines if we need to use a pre 2.2 calendar Uri, or a 2.2 calendar Uri, and returns the base Uri
 */
private String getCalendarUriBase() {
    Uri calendars = Uri.parse(BASE_CALENDAR_URI_PRE_2_2 + "/calendars");
    try {
        Cursor managedCursor = managedQuery(calendars, null, null, null, null);
        if (managedCursor != null) {
            return BASE_CALENDAR_URI_PRE_2_2;
        }
        else {
            calendars = Uri.parse(BASE_CALENDAR_URI_2_2 + "/calendars");
            managedCursor = managedQuery(calendars, null, null, null, null);

            if (managedCursor != null) {
                return BASE_CALENDAR_URI_2_2;
            }
        }
    } catch (Exception e) { /* eat any exceptions */ }

    return null; // No working calendar URI found
}
