Get Constant data from firebase in Android

How to get a constant value from firebase?

I'm maintaining a global count variable of number of friends a user has. Everytime user wants to add friends I need to increment that variable. How can I achieve this.

If I use a OnDataChangeListener() I will be able to read the DataSnapShot only when there is some change in data. But I want to read the data even when some part of the data has not changed.

OnDataChangeListener will be triggered one time when you add the listener.
So you don't need to wait until data changes, try using it.
