Question

Getting this error while attaching data to my arrayList.

        "ChatId": 13,
        "Name": [],
        "LoginUserId": "123xc-xcv4r4",
        "Message": [
            {
                "message": "Message 1 ",
                "Status": 0,

`Latitude": "", Longitude": " ` is your problem they should be like Latitude":0.00, Longitude:0.00 — akhilesh0707, Sep 16 '17 at 10:48

1) Try to change your AllUserMessages class Latitude, Longitude variables type double to String

2) Or change Latitude, Longitude from server site to double.
