JodaTime date and time parsing on Android

Question

I'm trying to parse date "10/13/2014 08:06 AM" Here is my code:

public static LocalDateTime parseDateTime(String dateAndTime) {
    try {
        if (dateAndTime.contains("-")) {
            return LocalDateTime.parse(dateAndTime.toUpperCase(), DateTimeFormat.forPattern("yyyy-MM-dd hh:mm aa"));
            //return DateTimeFormat.forPattern("yyyy-MM-dd hh:mm aa").parseDateTime(dateAndTime.toUpperCase());
        } else {
            return LocalDateTime.parse(dateAndTime.toUpperCase(), DateTimeFormat.forPattern("MM/dd/yyyy hh:mm aa"));
            //return DateTimeFormat.forPattern("MM/dd/yyyy hh:mm aa").parseDateTime(dateAndTime.toUpperCase());
        }
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
        return null;
    }
}

My parser fail:

java.lang.IllegalArgumentException: Invalid format: "10/13/2014 08:06 AM" is malformed at "AM"

Please help to investigate.

I'm using Android 4.4.4 and JodaTime 2.3

Sidenote: I'd probably use SimpleDateFormat instead. No need to add JodaTime. docs.oracle.com/javase/7/docs/api/java/text/… — dannyroa

I'am using it everywhere in my project. Especially for calculations such as plusHours — user3080265

There's Calendar & DateUtils for that: developer.android.com/reference/android/text/format/…. — dannyroa

Guys, questions is about JodaTime. I know that Android has it's own utils... — user3080265

I don't know what your locale is, but I can reproduce your problem with a locale like new Locale("hi", "IN") (my own system locale is different). So the solution for your problem is to specifiy the locale to English because text like "AM" is locale-specific and mainly used in English.

LocalDateTime ldt =
  LocalDateTime.parse(
    dateAndTime.toUpperCase(), 
    DateTimeFormat.forPattern("MM/dd/yyyy hh:mm aa").withLocale(Locale.ENGLISH));
