Detect if Firebase connection is lost/regained

Question

Is there a strategy that would work within the current Firebase offering to detect if the server connection is lost and/or regained?

Answer 1

For android you can make user offline by just a single function called onDisconnect()

I did this in one of my chat app where user needs to get offline automatically if network connection lost or user disconnected from Internet

DatabaseReference presenceRef = FirebaseDatabase.getInstance().getReference("USERS/24/online_status");

presenceRef.onDisconnect().setValue(0);

On disconnecting from network Here I am making online_status 0 of user whose Id is 24 in firebase.

getReference("USERS/24/online_status") is the path to the value you need to update on offline/online.

You can read about it in offline capabilities

Note that firebase takes time around 2-10 minutes to execute onDisconnect() function.
