Moshi: parse JSONArray from Retrofit

[regifr]

I would like to insert the data JSONArray to the adapter
but I have a problem to send it

//the JSON
{
  "data": {
    "products": {
      "datum": [
        {
          "product_id": 7,
          "seller_id": 14,
          "product_name": "Cap",
          "price": "55000"
        },
        {
          "product_id": 8,
          "seller_id": 14,
          "product_name": "Jacket",
          "price": "300000"
        },
        {
          "product_id": 9,
          "seller_id": 14,
          "product_name": "T-shirts Blue",
          "price": "100000"
        }
      ]
    }
  }
}

//ProductActivity.java
ProductAdapter padapter;
List<Datum> data = new ArrayList<>();

try {
    Moshi moshi = new Moshi.Builder().build();
    final String dataJsonResponse = response.body().getData().getProducts().getDatum().toString();
    Type type = Types.newParameterizedType(List.class, Datum.class);
    JsonAdapter<List<Datum>> adapter = moshi.adapter(type);
    data = adapter.fromJson(dataJsonResponse);
} catch (Exception e) {
    Log.d("onResponse", "There is an error");
    e.printStackTrace();
}
padapter = new ProductAdapter(getApplication(), data);
recyclerView.setAdapter(padapter);

//Datum.class
@Override public String toString() {
    return String.format("%s%s%s", sellerId, productName, price);
}

when I check the in Debug, the 'dataJsonResponse' value is
[14Cloth55000, 14Jacket3000, 14T-shirts Blue100000]
and the 'data' size = 0

is the 'dataJsonResponse' is right?
why the size of 'data' is 0?

The logged exception will tell you the problem.

Your JSON is malformed. You either need to fix your server, pre-process it
to correct the format, or enable lenient parsing.

No action for Moshi to take here.

If you think it's a bug in Moshi, a contained test case is the best way to show it.
Otherwise and in all likelihood, what Jake said.

[regifr]

thanks for the response, I got the point 👍

[desgraci]

It was added on the Moshi factory, do you guys think is possible to add the same to the Moshi.Builder? Sometimes we receive the server as it is, broken and incomplete, like my dreams :'(

[NightlyNexus]

@desgraci Do you mean the lenient option?

static final JsonAdapter.Factory LENIENT_FACTORY = new JsonAdapter.Factory() {
  @Override
  public JsonAdapter<?> create(Type type, Set<? extends Annotation> annotations, Moshi moshi) {
    return moshi.nextAdapter(this, type, annotations).lenient();
  }
};

Install this as your first factory on your Moshi.Builder.

Or, if you are using Retrofit, MoshiConverterFactory.create(moshi).asLenient() will create lenient adapters.
