Firebase Database: How to read value of a single node without looping through a snapshot

enter image description here

My firebase database is shown above.

I am able to modify the value of isAdminOnline using the following code:

    DatabaseReference mFirebaseDatabaseReference;      mFirebaseDatabaseReference = FirebaseDatabase.getInstance().getReference();      mFirebaseDatabaseReference.child("*isAdminOnline*").setValue("yes");  

What is the shortest code to read the value of isAdminOnline without having to loop thru the entire database?
