【问题描述】：
我想使用 HashMap 在现有的 firestore 文档中添加一些字段。 首先我创建了firestore db{collection("UsersProfile").document(currentUserID)} 并使用了set() 方法，然后为了添加字段(key, value)，我使用了update() 方法。但未添加 Field 值。
我希望你的帮助。谢谢。

-
首先，停止忽略错误。使用
Log.d(TAG, error.getMessage());。您是否在 logcat 中打印了一些内容？ -
我想在 db.collection("UsersProfile").document(currentUserID) 中添加五个字段（profileImage、pictureOne、pictureTwo、pictureThree、pictureFour）。但是其中两三个被添加到文档中（currentUserId）。
