This class is rendering an UnsupportedOperationException when the size of the array is 1.

The solution may look like this:

@OverRide
public List deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
List multimediaList = new ArrayList<>();
String jsonString = null;

    try {
        jsonString = json.getAsString();
    } catch (IllegalStateException | UnsupportedOperationException e) {
       // Do Nothing
    }

    if (jsonString == null || !TextUtils.isEmpty(jsonString)) {
        JsonArray jsonArray = json.getAsJsonArray();
        for (int i = 0; i < jsonArray.size(); i++) {
            multimediaList.add(context.deserialize(jsonArray.get(i), Multimedia.class));
        }
    }

    return multimediaList;
}
