Android Kotlin代码在运行时出现“访问隐藏字段”错误

标签： android firebase kotlin google-cloud-firestore

我正在Android Studio上的Kotlin中构建一个Android应用程序。我正在将其连接到Firebase和Firestore。

不幸的是，曾经使用了一段时间的代码现在已经开始在运行时中断，并且出现了一些错误，这些错误看起来应该在编译时就被捕获了。

我正在“ Pixel XL API 29”仿真器上对其进行测试。我尝试删除一些代码块等以找出可能发生的情况，但是错误消失了，因为删除了一段很长时间以来我什至没有碰到的代码：

db = FirebaseFirestore.getInstance()
val userData = hashMapOf(
    "user-id" to "theuserid",
    "language" to "hindi"
)

db.document("Data/Users/$userId").set(userData,SetOptions.merge())

（我在这里也有其他事件侦听器等。为了简洁起见，我省略了它。而且我知道这是一个可选代码。拥有或不拥有侦听器都没有什么区别。）

所以我想知道这是怎么回事。在执行应用程序时，执行甚至没有达到我最近更新的代码部分。

以下提到的错误。任何想法可能出什么问题吗？

更新： 阅读评论后，我认为问题可能超出显示的警告范围。我查看了线程转储，发现相当多的线程处于“等待”状态，其中之一是Firestore线程。

可能是什么原因造成的？

更新2：已设法解决

我正在尝试各种东西，并更改了将“ Long”参数传递给firestore的“ update”功能的方式，这似乎已经奏效。不确定究竟是什么使它起作用。我先检查它是否为零，或对!!

的不同处理

旧：

db = FirebaseFirestore.getInstance()
batch = db.batch()
batch.update(
 db.document("sunday"), "checked-items",
 FieldValue.increment(itemTable["sunday"]?.checkedItems?.toLong()!!)
)
batch.commit()

新功能：

db = FirebaseFirestore.getInstance()
batch = db.batch()
if ( itemTable["sunday"]!!.checkedItems > 0 ) {
 batch.update(
 db.document("sunday"), "checked-items",
 FieldValue.increment(itemTable["sunday"]!!.checkedItems.toLong())
 )
}
batch.commit()

我应该将其发布为答案吗？

更新3：并且它不再起作用。

进行了一些微不足道的更改，例如添加日志事件等，然后再次中断。即使撤消所有更改，错误也不会消失。我现在很确定，它与我对代码所做的更改无关。看了线程转储，这就是我现在所拥有的：

更新4：最终解决

因此，就像还有很多其他事情一样，此问题也与我所做的代码更改完全无关。 Firestore的呼叫被挂起了，因为我的每日写操作配额已结束。不知道为什么通话没有失败，而是挂了。我没有调用我的Failure事件侦听器。

1 个答案:

答案 0 :(得分：0)

在Firestore中检查我的每日“写操作”配额的状态导致了突破。由于配额用完，我的Firestore通话被挂断了。即使失败事件侦听器也没有被调用。

现在，我更改为“随用随付”计划，它似乎运行良好。
