Error when parsing JSON using GSON

Question

Error when parsing JSON using GSON

You need to parse the JSON in android, using GSON, into the Map object. JSON comes from Yandex. Translate. I tried to use the following:

Gson gson = new GsonBuilder().create();

try {
        Response<Object> response = call.execute();
        JsonReader reader = new JsonReader(new StringReader(response.body().toString()));
        reader.setLenient(true);
        Map<String, String> map = gson.fromJson(reader, Map.class);

        for (Map.Entry pair: map.entrySet()) {
            if (pair.getKey().equals("text")) {
                translatedText = pair.getValue().toString();
            }
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

This works well when trying to translate a single word. But when translating several words, an error occurs:

com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Unterminated array at line 1 column 40 path $.[1]

How do I fix this ?

Sample JSON:

{
    "code": 200,
    "lang": "en-ru",
    "text": [
        "Здравствуй, Мир!"
    ]
}

import com.google.gson.Gson;
import java.util.Arrays;

public class Model {

    private Integer code;

    private String[] text;

    private String lang;

    public static void main(String[] args) {

        Gson gson = new Gson();

        String json = "{\n"
                + "    \"code\": 200,\n"
                + "    \"lang\": \"en-ru\",\n"
                + "    \"text\": [\n"
                + "        \"Здравствуй, Мир!\"\n"
                + "    ]\n"
                + "}";

        Model fromJson = gson.fromJson(json, Model.class);

        System.out.println(fromJson);
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String[] getText() {
        return text;
    }

    public void setText(String[] text) {
        this.text = text;
    }

    public String getLang() {
        return lang;
    }

    public void setLang(String lang) {
        this.lang = lang;
    }

    @Override
    public String toString() {
        return "Model [code = " + code + ", text = " + Arrays.toString(text) + ", lang = " + lang + "]";
    }
}
