java.text.ParseException：仅限某些设备上的无法解析的日期

我面临一个非常奇怪的问题。 在解析此字符串时2016-09-06 05:18:06.023 PM我得到以下exception – java.text.ParseException: Unparseable date: "2016-09-06 05:18:06.023 PM" (at offset 24)

奇怪的是，发生此exception的设备是朋友的Nexus 5 。 但是，如果我在我的Nexus 5 / 其他几个仿真器上调试相同的字符串，它可以正常工作。

这是我正在使用的代码。 SimpleDateFormat属于java.text包。 Date属于java.util包

  SimpleDateFormat formatGMT = new SimpleDateFormat("yyyy-MM-dd KK:mm:ss.SSS a"); formatGMT.setTimeZone(TimeZone.getTimeZone("GMT")); try { date = formatGMT.parse("2016-09-06 05:18:06.023 PM"); } catch (ParseException e) { Crashlytics.log(Log.ERROR, "DB Insertion error", e.getMessage().toString()); Crashlytics.logException(e); e.printStackTrace(); } 

这是完整的堆栈跟踪。

它可能会受到符号的影响对于设备默认语言环境中的am / pm，因此请尝试使用以下语言环境来解析它将帮助您的日期。

  SimpleDateFormat formatGMT = new SimpleDateFormat("yyyy-MM-dd KK:mm:ss.SSS a", Locale.US); formatGMT.setTimeZone(TimeZone.getTimeZone("GMT")); try { date = formatGMT.parse("2016-09-06 05:18:06.023 PM"); } catch (ParseException e) { Crashlytics.log(Log.ERROR, "DB Insertion error", e.getMessage().toString()); Crashlytics.logException(e); e.printStackTrace(); }
