How to parse Json using Retrofit if key is inside of another object

Question

Can anyone help me in parsing below json using retrofit?

{
  "key1": "value",
  "key2": {
           "key3": "value2",
           "key4": "some random text is here"
          },
  "value2" : {
               -- actual data is here ---
             }
}

here "value2" will change. i'm not able to figure how to get the value of "Key3" and get the actual data using Retrofit.
Thanks in advance.

you can json data into pojo class put in your json data in below website it generate pojo class..

http://www.jsonschema2pojo.org/

add below dependency into app level gradle file ..

    implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

then after when you make retrofit object pass this line ..

 retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(client.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build();

You can do it like this, lets say you have JSONObject with above mentioned json.

You can parse it like String value = jsonObject.optString("key1");

Retrofit supports converterFactory, you can try Gson or Jackson with it

Find an example below

Add dependency in gradle,

implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

Java Code

 new Retrofit.Builder().baseUrl(BuildConfig.BASE_URL).
            addConverterFactory(GsonConverterFactory.create()).
            client(okHttpClient).
            build();

 public interface GetAllAPI {
        @GET("/all")
        List<Country> getCountries();
    }

Try out this:

try {
        JSONObject jsonObject = new JSONObject("Your_json_string");
        String key1 = jsonObject.optString("key1");
        JSONObject key2 = jsonObject.optJSONObject("key2");

        String value2 = key2.optString("key3");//It will get value

        JSONObject jsonObjectValue2 = jsonObject.optJSONObject(value2);// now use value2 here for actual result
        String finalValue = jsonObjectValue2.optString("next_value");
        //....and so on

    } catch (JSONException e) {
        e.printStackTrace();
    }
