Android 断开连接然后重新启动Internet连接后Firebase实时数据库未连接

在我的应用程序中，在单击某个按钮的某个点，应用程序需要在RTDB上执行操作（具体地说，检查节点的存在）。为了确保用户在未连接到网络时收到警告，我正在进行类似的检查

private fun checkNet（）：布尔值{
val cm=context？.getSystemService（context.CONNECTIVITY_服务）作为ConnectionManager
val netC=cm.getNetworkCapabilities（cm.activeNetwork）
返回(
netC！=null&&
netC.hascability（NetworkCapabilities.NET\u CAPABILITY\u INTERNET）&&
netC.hascability（NetworkCapabilities.NET\u CAPABILITY\u验证）&&
（网络传输（网络能力传输）||
netC.hasTransport（NetworkCapabilities.TRANSPORT_WIFI））
)
}

然后在必要时调用该函数

但我面临的问题是，如果internet连接丢失后又恢复，那么即使连接了侦听器，它也不会连接到服务器。我意识到这需要时间，但是连接到

.info/connected

位置的侦听器在连接到该位置时从不触发

override-fun-onStop（）{
super.onStop（）
Firebase.database.getReference（“.info/connected”）.removeEventListener（侦听器）
}
覆盖有趣的onStart（）{
super.onStart（）
Firebase.database.getReference（“.info/connected”）.addValueEventListener（listener）
}
对象侦听器：ValueEventListener{
override fun onCancelled（错误：DatabaseError）=单位
覆盖数据更改（快照：DataSnapshot）{
val isCon=if（snapshot.value！=null）snapshot.value为布尔值
否则错误
if（isCon）Log.d（标记“connected”.err（））
else Log.d（标记“not connected”.err（））
}
}

即使通过离开应用程序并返回应用程序触发了

onStart（）

，侦听器也不会记录

已连接的

。只有当我关闭整个应用程序，然后重新打开它时，它才会连接

因此，我的问题是，我是否假设

.info/connected

的行为是正确的，如果是，那么我该怎么做才能确保它在存在internet连接的情况下在合理的时间段后连接到RTDB

编辑-正如@FrankVanPuffelen所建议的，我继续并启用了调试日志记录。在导航到片段并在存在internet连接的情况下访问数据库后，日志输出被删除

在所有这些之后，它大约在一分钟后给出了一个输出，但行为并不一致，我希望日志消息能够提供一些关于这一点的见解。

Firebase客户端尝试连接到服务器时出现指数级后退，因此根据您没有连接的时间长短，可能需要一些时间才能重新连接？你等它重新连接了多久？它可能也有助于检查/包括输出。@FrankVanPuffelen我想我等了大约半分钟才重新连接。那么，当我打开移动数据后等待大约10分钟时，这是否足以导致在它重新连接之前的大量时间？此外，我将继续启用调试日志记录，并包括它的输出，因为它似乎可能会带来一些见解。是的，在30秒断开连接时，它肯定会比您所说的更快地重新连接。希望调试日志能够提供一些见解，因为它们准确地显示了客户端尝试（重新）连接的时间以及它得到的响应（如果有的话）。Firebase客户端尝试连接到服务器时出现指数级回退，因此根据您没有连接的时间长短，可能需要一些时间才能重新连接？你等它重新连接了多久？它可能也有助于检查/包括输出。@FrankVanPuffelen我想我等了大约半分钟才重新连接。那么，当我打开移动数据后等待大约10分钟时，这是否足以导致在它重新连接之前的大量时间？此外，我将继续启用调试日志记录，并包括它的输出，因为它似乎可能会带来一些见解。是的，在30秒断开连接时，它肯定会比您所说的更快地重新连接。希望调试日志能够提供一些见解，因为它们准确地显示了客户端何时尝试（重新）连接以及得到了什么响应（如果有的话）。
