Firebase Android addListenerForSingleValueEvent sometimes not returning data

Question

When my application starts, I check the current user\'s details in my Firebase database (I\'m storing it\'s uid for that).

I\'m attaching addListenerForSingleValueEv

My guess is user/:id does not exist. Double-check your error output:

DatabaseReference newUser = FirebaseDatabase.getInstance()
    .getReference("users")
    .child(uid)
    .addListenerForSingleValueEvent(new ValueEventListener()     
        @Override
        public void onDataChange(DataSnapshot snapshot) {
            if (snapshot.exists()) {
                Log.i(TAG, snapshot.val());
            } else {
                Log.e(TAG, "Not found: " + uid);
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {
            Log.e(TAG, databaseError.toString();
        }
    });
