Date Parser Exception

[郑蔚]

the code is:

Gson gson = new GsonBuilder().setDateFormat("EEE MMM dd HH:mm:ss Z yyyy").create();
Date d = gson.fromJson("Tue May 31 17:46:55 +0800 2011", Date.class);

 

I use these code in my android project , get the JsonSyntaxException.

But when i use these date format with SimpleDateFormat , it's works.

Any one have idea where is the problem?

the trackstack: 

Exception in thread "main" com.google.gson.JsonSyntaxException: Tue

Could it be as simple as missing double quotes *within* the date
string? Shouldn't that be:

Date d = gson.fromJson("\"Tue May 31 17:46:55 +0800 2011\"", Date.class);

It works in the example code .

but I need to parse the date string from some api  which I can not modify .

any other ways ? Or, I just to use the  custom deserializer ？
