StrictMode在一行代码中显示10个错误

Question

我正在运行StrictMode.enableDefaults()来清理我的代码，并且我有一行代码将ZoneId设置为单行代码，每10次违反StrictMode的时间大约为195ms 。该行上方的Log.d语句在 Logcat 中仅显示一次。如果使用ZoneId.of(tz.getID())，则会收到相同的错误。

这是怎么回事？我检查了ZoneId的来源，原因对我来说并不明显。这是来自ZoneId的解析输入吗？日志时间仅从 16：46：09.079 到 16：46：09.080 ，否则10条堆栈轨迹看起来相同。

我真的失去了大约195ms x 10的错误吗？或者这是某种错误？谢谢

例程出现错误：

if (lastUpdateZoneOffset.equals(utcOffset)) {
        // last update offset is zero, so add back time from observation station time zone
        Log.d(TAG, "tz.getID()");
        //ZoneId observationStationZoneId = ZoneId.of(tz.getID());
        ZoneId observationStationZoneId = ZoneId.of("America/Denver"); **<---Error Here**
        ZonedDateTime zdt = offsetDateTime.atZoneSameInstant(observationStationZoneId);
        // format to 14 Apr 4:16 PM Note: the "a" pattern only allows upper case for AM/PM
        lastUpdate = zdt.format(DateTimeFormatter.ofPattern("dd MMM h:mm a"));
        lastUpdate += " " + tz.getDisplayName(true, SHORT);
    } else {
        lastUpdate = offsetDateTime.format(DateTimeFormatter.ofPattern("dd MMM h:mm a"));
        lastUpdate += " " + tz.getDisplayName(true, SHORT);
    }

典型堆栈跟踪：
