Android – manage online status in cloud firestore

In the firebase real-time database, we can easily manage the user status by keeping the reference to the node and updating it, as shown below:

DatabaseRef presenceRef = FirebaseDatabase.getInstance().getReference("disconnectmessage");

presenceRef.onDisconnect().setValue("I disconnected!");

If I want to do the same thing in cloud firestore, is there a way to achieve it?

resolvent:

You can easily use cloud firestore and realtime database in the same project. For status, we recommend that you still use real-time database to process it
