how to send JSONObject into retrofit API call android

Question

I have implemented first time retrofit in my android code and facing follwing issues

getting following error : java.lang.IllegalArgumentException

Answer 1

You are using the Android internal Json APIs. You need to use Gson's classes instead.

Call<JsonObject> sendLocation(@Body JsonObject jsonObject);

Hence the import statement

import com.google.gson.JsonObject;

Another error is passing the Callback as a parameter to the request

Call<JsonObject> call = apiService.sendLocation(jsonObject);
call.enqueue(new Callback<JsonObject>() {
   @Override
   public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
      Log.d("response","Getting response from server : "+response);
   }

   @Override
   public void onFailure(Call<JsonObject> call, Throwable t) {
      Log.d("response","Getting response from server : "+t);
   }
});
