thanks in advance to those who could see my publication. I'm working with services and I have the following JSON
"custom_attributes": [
{
"attribute_code": "meta_description",
"value": "Calzado"
},
{
"attribute_code": "category_ids",
"value": [
"2",
"151",
"161",
"163"
]
}
]
and what I try gives the following error if the Value attribute I place in a List.
java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 8375 path $.custom_attributes[0].value
model
public class CustomAttribute {
@SerializedName("attribute_code")
private String attributeCode;
@SerializedName("value")
private List<String> value = null;
public String getAttributeCode() {
return attributeCode;
}
public void setAttributeCode(String attributeCode) {
this.attributeCode = attributeCode;
}
public List<String> getValue() {
return value;
}
public void setValue(List<String> value) {
this.value = value;
}
}

"custom_attributes" itself is an array with objects
I assume somewhere you have List<CustomAttibute>
and that array has no consistent object format within. value is both a String, and a List<String>.
The best you can do is private Object value = null;, then you must check its type and cast it later at runtime, or you can not use Retrofit w/ the Gson converter, as Gson expects consistently formed object types within lists (meaning for every JSON key, there is only one value type).

The error you are getting means that you are telling the model to expect an array where it should be getting a string.
In order to solve your issue easily you can use this online resource to generate your model (by just copy pasting the json file)
or you can use this plugin to generate you model directly from android studio!
Hope you got your answer!
