You can check if a user in the Sendbird application is currently connected to the Sendbird server. For group channels only, you can check whether each member is currently connected to the server.
val userIds = listOf("Jeff")
val query = SendbirdChat.createBlockedUserListQuery(
BlockedUserListQueryParams().apply {
userIdsFilter = userIds
}
)
query.next { users, e ->
if (e != null) {
// Handle error.
}
// users?.first() = "Jeff"
if (users?.first()?.connectionStatus == User.ConnectionStatus.ONLINE) {
// "Jeff" is currently online.
// User.ConnectionStatus consists of ONLINE and OFFLINE.
}
}
