Firebase update user's status

Question

I've read Offline Capabilities on Firebase Docs and it wasn't helpful enough.

The thing that I want to do is if user goes offline I want to set status offline. The problem is if user lost connection, user won't be able to update the status.

where are you doing it? You can find out with the user lost connection and then run code in there.... https://stackoverflow.com/a/21226812/8200290 — letsCode, Aug 24 '17 at 20:49

Read carefully the section of that page called Presence Management. It describes how to use an onDisconnect handler to change a location of the database when the app loses its connection.

For example, to set the location "disconnectmessage" to the value "I disconnected!" when the connection is lost:

DatabaseRef presenceRef = FirebaseDatabase.getInstance().getReference("disconnectmessage");
presenceRef.onDisconnect().setValue("I disconnected!");

It works well but when I cut my internet connection, it does not work. How can I solve this? – Burak Aug 24 '17 at 21:10

The server may take a few minutes before it detects that the connection has disappeared. It depends on the socket timing out. – Frank van Puffelen Aug 24 '17 at 21:11
