I've following JSON Array and I wanted to parse that to get all three email address into a three separate variables. I wanted this to be done using Google GSON library. How we can do that ?
string jsonarrays=
[
{
"Id": "0e9b73bc-cf32-48b4-88cc-ee4ff8c3a823",
"FirstName": "Chris",
"LastName": "Rogers",
"Height": "180cm",
"Weight": "74kg",
"location": "UK",
"email": "[email protected]"
},
{
"Id": "0e9b73bc-7cd7-48b4-88cc-ee4ff8c76vcv",
"FirstName": "Lavina",
"LastName": "Langer",
"Height": "170cm",
"Weight": "63kg",
"location": "Poland",
"email": "[email protected]"
},
{
"Id": "213jdsj-cf32-48b4-1119hshjakakaaka",
"FirstName": "Mike",
"LastName": "Harford",
"Height": "184cm",
"Weight": "80kg",
"location": "Paris",
"email": "[email protected]"
}
]
I've write some code
Gson myGson = new Gson();
JsonParser jsonParser = new JsonParser();
JsonArray userArray =jsonParser.parse(jsonarrays).getAsJsonArray();
List messageArray = new ArrayList();
for (JsonElement aUser : userArray ){
User aTwitterUser = myGson.fromJson(aUser, User.class);
messageArray.add(aTwitterUser);
}
The error that I am getting
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING
