LocalDateTime not parsing for a specfic device [duplicate]

这个问题在这里已经有答案了：
如何在 Java 中更改时间格式 - “am/pm” 与 “am/pm” （2 个答案）
7个月前关闭。

我正在使用此方法将 String 解析为 LocalDateTime（由 ThreeTen，而不是 Java 的字符串）。

输入：28-Aug-20 10：37：41 AM BST

  private fun toLocalDate(date: String?): LocalDateTime? {
        return try {
            val inputFormat = DateTimeFormatter.ofPattern("dd-MMM-yy hh:mm:ss a")
            val formattedDate = date?.replace(" BST", "")
            LocalDateTime.parse(formattedDate,inputFormat)
        } catch (e: Exception) {
            e.printStackTrace()
            null
        }

    }

现在的问题是，此方法在 Android 模拟器 （13） 和其他一些设备 （11/12） 上运行良好，但在特定设备三星 Galaxy S21 FE （13） 中崩溃。我不知道为什么此代码在此设备上不起作用。

下面是崩溃日志

我尝试更改为 LocalDate、OffsetDateTime、在 DateTimeFormatter 上添加区域设置，但没有奏效

Android Kotlin java-time localdate

在 DateTimeFormatter 上添加区域设置，但不起作用您添加了哪个区域设置？我向你保证，添加正确的语言环境是前进的方向。
1赞 Anonymous 4/17/2023
顺便说一句，您要删除的是巴西夏令时、孟加拉国标准时间、布干维尔标准时间、英国夏令时还是其他时间？如果你知道哪个，你可以把它解析为一个时区缩写，你应该更喜欢哪个，当它基本上是模棱两可的。BST

我做错了吗？是的。您需要提供字符串正在使用的区域设置，而不是用户正在使用的区域设置。请参阅此问题。有关时区缩写，请参阅 java.time 库中映射到错误的 ZoneId 的 IST。

val inputFormat = DateTimeFormatter.ofPattern("dd-MMM-yy hh:mm:ss a", Locale.ENGLISH)

这解决了我的问题。

上一个：将 LocalDate 转换为 java.util.Date [duplicate]

下一个：LocalDates 之间的时间段会产生错误的结果
