Moshi Determine if JSON is array or single object

Answer 1

Using @Eric's comment, I came up with the correct code below:

public static  List loadFakeData(String url, Class cls){
    List list = new ArrayList<>();
    Moshi moshi = new Moshi.Builder().build();
    try {
        JsonReader reader = JsonReader.of(runHttpClient(url));
        JsonReader.Token token = reader.peek();
        if (token.equals(JsonReader.Token.BEGIN_ARRAY)) {
            Type type = Types.newParameterizedType(List.class, cls);
            JsonAdapter> adapter = moshi.adapter(type);
            list = adapter.fromJson(reader);
        } else if (token.equals(JsonReader.Token.BEGIN_OBJECT)){
            JsonAdapter adapter = moshi.adapter(cls);
            T t = adapter.fromJson(reader);
            list.add(t);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return list;
}
