重新连接后,Firestore和实时数据库的响应时间过长

标签: android firebase firebase-realtime-database

关闭wifi并立即将其重新打开后,首次尝试从firestore中获取数据的时间太长,导致将其保存为变量时会返回null值。 Firebase实时数据库在第一次尝试写入时也会花费大约40秒的时间。以后每次读取,写入和删除时,它几乎都是瞬时的。

以下是我的gradle实现

  • com.google.firebase:firebase-core:16.0.4
  • com.google.firebase:firebase-firestore:17.1.2
  • com.google.firebase:firebase-database:16.0.5

有什么方法可以使第一次读写更快?

断开连接后,Firebase客户端将进入指数退避循环,您无法从应用程序代码中控制该循环。

但是40秒钟对于短暂的断开似乎有点长。您可能想要enable debug logging并检查logcat的输出以查看它是否显示出为什么花这么长时间的任何提示。
