You can try it:

mReference.child("demo").orderByChild("fname").equalTo("John").addListenerForSingleValueEvent(
                new ValueEventListener() {
                    @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                 dataSnapshot.getRef().setValue(null);
            }


           @Override
             public void onCancelled(DatabaseError databaseError) {
                  Log.w("TodoApp", "getUser:onCancelled", databaseError.toException());
             }
   });
