The problem is that i lost the source of this lib last year.
I did decompiled the old version and made a new one out of it.
It is "working" for me using the newest Maven Artifacts.
This is a log of my Testapp using testdata i capture just today...
But it still have some issues.
- Limiting the results does not work as expected
- Filtering does not work as expected.
- Based on this one should use a real flat structure of the DB-Content and uses the tree objects in a flat structure as you where queying against the hole Database.
- Without having special classes which you would use in your app (needs to be done in java, compiled together with my library sources as you would need to adapt some parts of it.
- you can use simple Maps (not too complicated) to store in a Tree.
- It is not really satisfactory at this stage i guess.
But it is working (at least my V2.82)

I also wrote a wrapper for the Firebase Firestore Database. But this Firebase lib is still in Beta so i need to wait for an final release (integrated in google play services).
This is working partially too (mostly same problems as in the Realtimedatabase library. Problems with Filtering, Ordering, Limiting))
Honestly; i dont know as you are using an Old Version of the Library.

You also need to download json databind from

Download the bundle and use the contained jar
