Retrofit get JsonSyntaxException Error

Question

when i try to get this result from webService :

{
    "bankInfo":
    [
        {
            "id": "2",
            "title": "BANK A",
            "alias": "A"
        },
        {
            "id": "3",
            "title": "BANK B",
            "alias": "B"
        },
        {
            "id": "4",
            "title": "BANK C",
            "alias": "C"
        }
    ]
}

with this code:

ActiveBanks activeBanks = new ActiveBanks();

Call<ActiveBanks> call = behandamService.activeBanksCall(activeBanks);
call.enqueue(new Callback<ActiveBanks>() {
    @Override
    public void onResponse(Call<ActiveBanks> call, final Response<ActiveBanks> response) {
        if (response.isSuccessful()) {

        }
    }
    @Override
    public void onFailure(Call<ActiveBanks> call, Throwable t) {
        t.printStackTrace();
        if (t.getMessage() != null) Log.e("ActiveBanks: ", t.getMessage());
    }
});

and ActiveBanks structure :

public class ActiveBanks {
    private JSONArray bankInfo;

    public ActiveBanks() {
    }

    public JSONArray getBankInfo() {
        return bankInfo;
    }

    public void setBankInfo(JSONArray bankInfo) {
        this.bankInfo = bankInfo;
    }
}

i get this error:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 14 path $.bankInfo

Unclear why you are trying to parse json back into `JSONArray`. You need a `List` class there instead — OneCricketeer, Jun 17 '17 at 08:09

You have to chnage model class to this:

public class BankInfo {

@SerializedName("id")
@Expose
private String id;
@SerializedName("title")
@Expose
private String title;
@SerializedName("alias")
@Expose
private String alias;

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public String getAlias() {
return alias;
}

public void setAlias(String alias) {
this.alias = alias;
}

}

And main model class:

public class ActiveBanks{

@SerializedName("bankInfo")
@Expose
private List<BankInfo> bankInfo = null;

public List<BankInfo> getBankInfo() {
return bankInfo;
}

public void setBankInfo(List<BankInfo> bankInfo) {
this.bankInfo = bankInfo;
}

}

That's not correct. The json is an object, not a List – OneCricketeer Jun 17 '17 at 08:09
right, there is problem in json format – Divyesh Patel Jun 17 '17 at 08:09
I understand that. Feel free to edit your answer to correct the problem – OneCricketeer Jun 17 '17 at 08:11
In other words, `Call` is fine. The contents of the ActiveBanks class is not – OneCricketeer Jun 17 '17 at 08:13
