Answer 1

I too ran of this issue. but i am not sure if this was your case , (i am using Retrofit2)

on my case i need to handle error, and success messages.

On Success

{
"call_id": 1,
"status": "SUCCESS",
"status_code": "SUCCESS",
"result": {
    "data1": {
        "id": "RFP2UjW7p8ggpMXzYO9tRg==",
        "name": "abcdef",
        "mobile_no": "96655222",
        "email": ""
    },
    "data2": [
        {
            "no": "12345"
        },
        {
            "no": "45632"
        }
    ]
}
}

On Error,

{
"call_id": 1,
"status": "FAILED",
"status_code": "NO_RECORDS",
"error": {
    "error_title": "xxx",
    "error_message": "details not found"
}
}

for this i just created another POJO Error,

public class ValidateUserResponse {
@SerializedName("call_id")
public String callId;
@SerializedName("status")
public String status;
@SerializedName("status_code")
public String statusCode;
@SerializedName("result")
public ValidateUserResult result;
@SerializedName("error")
public Error error;
}

Error.java

public class Error {
@SerializedName("error_title")
public String errorTitle;
@SerializedName("error_message")
public String errorMessage;
}

ValidateUser.java

public class ValidateUserResult {

@SerializedName("auth_check")
public String authCheck;
@SerializedName("data1")
public Data1 data1;
@SerializedName("data2")
public List data2;
}

in the above case if the result key on json contains data1,data2 then the ValidateUserResult.java get initialised. if error then the Error.java class get initialized.
