java - 如何将数组数据上传到 Cloud Firestore

Question

我有以下代码用于上传到 Firestore：

Map<String, Object> map = new HashMap<>();
 map.put(ConstHolder.PHONE_NUMBER_KEY, phone_number);
        map.put(ConstHolder.STATE_KEY, state());
        map.put(ConstHolder.PATH_KEY, cloudFilePath);
        map.put(ConstHolder.DATE_KEY, date);
        map.put(ConstHolder.CREATED_DATE_KEY, createdDate);
        map.put(ConstHolder.HINT_KEY, textFromHints());

到目前为止，地图的所有字段都只是 String 和 int。但是现在，我还需要使用快速序列化将对象保存为字节数组，所以我添加了：

            FSTConfiguration conf = FSTConfiguration.createDefaultConfiguration();
            byte placeByteArray[] = conf.asByteArray(place);
            Log.w(TAG, "Place byte array : " + Arrays.toString(placeByteArray));
            map.put(ConstHolder.PLACE_KEY, placeByteArray);

我也试过：

            FSTConfiguration conf = FSTConfiguration.createDefaultConfiguration();
            byte placeByteArray[] = conf.asByteArray(place);
            Log.w(TAG, "Place byte array : " + Arrays.toString(placeByteArray));
            map.put(ConstHolder.PLACE_KEY, Arrays.asList(placeByteArray));

但我不断收到这个异常：

Caused by: java.lang.IllegalArgumentException: Invalid data. Arrays are not supported; use a List instead

FirebaseFirestoreHelper.kt 将以下代码保存到 Firestore：

fun addCall(callMap: Map<String, Any>) {
        val db = FirebaseFirestore.getInstance()
        db.collection(App.getFirebaseAuthHelper().getUserID()!!)
                .add(callMap)
                .addOnSuccessListener { documentReference -> Log.d(TAG, "DocumentSnapshot added with ID: " + documentReference.id) }
                .addOnFailureListener { e -> Log.w(TAG, "Error adding document", e) }

    }
