Unable to generate POJO(model) class using Gson format

I want to parse JSON using Retrofit 2.1.0 library so i used Gson format plugin for creating POJO (model) class but I am not able to create it because of this Gson format exception error -- 

 com.intellij.util.IncorrectOperationException: Incorrect field '/** 
           * 0 : {"lat":"23.0124","long":"72.5228","question":"caluculate 1+2","hint":"1,2,3","questionAudioUrl":"http://audio/1480919241.mp3"}
           * type : type1
           */ 
           @com.google.gson.annotations.SerializedName("0")private  0Bean value0 ; '

And my JSON is also valid I am validating using this site http://jsonformatter.org/

Here is my json

    }
  }
}

I know there is http://www.jsonschema2pojo.org/ to generate model class but it create separate classes not nested class so it's hard to manage so many classes.

QUE 1: How can i generate model class using json?

QUE 2: Is there any way i can get string response using retrofit 2.1.0 i tried RequestBody but not work.

Is there any better solution for that??

1) I am not too familiar with the Gson formatter plugin, but it looks like it is generating an invalid type name "0Bean". It looks like you can edit the names and types of what it generates. Otherwise, using the site you mentioned or hand coding the POJOs are options. Also, if you able to rename elements in your JSON, don't name fields with numbers like "0".

2) You can get a string response by using the scalars converter --

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(/* your url */)
    .addConverterFactory(ScalarsConverterFactory.create())
    .addConverterFactory(GsonConverterFactory.create()) /* if you also still need GSON, if not, you can leave this off */
    .build();

and in your interface -- 

@GET("/mypath")
Call<String> getMyStuff();

You will need to add -- compile 'com.squareup.retrofit2:converter-scalars:2.1.0' to your gradle file.
