Describe the bug I tried to use onChildChange function to observe ChildEvent.Added event with wanted datatype Map::class.java(Kotlin). When DB child added, but no luck.

To Reproduce Steps to reproduce the behavior:

  1. Write code: ref.inReference("users/${it.userInfo.uid}").onChildChange(Map::class.java, ChildEventType.ADDED).then(Consumer<Map<String, Any>>{// TODO})
  2. Add child by Firebase-Function
  3. Child added event doesn't trigger

Expected behavior A clear and concise description of what you expected to happen. onChildChange observe child added event with Map.class wanted datatype doesn't work when child added.

@wangdong20 I think you are listening on the wrong path. According to firebase documentation:

child_added is triggered once for each existing child and then again every time a new child is added to the specified path.

You should listen on inReference("users").onChildChange(List.class, ChildEventType.ADDED). I know that you already switched yourself to official android SDK so I'm going to close the issue. Pls feel free to re-open it :)
