To put data inside mDatabase = FirebaseDatabase.getInstance().getReference().child("flamelink"); you have to use .setValue() method you will fine more here .
and to retrieve from location flamelink/environments/production/content/contentPlaces/en-US Use

   DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference().child(flamelink).child(environments).child(production).child(content).child(contentPlaces).child(en-US);
    databaseReference.addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                 // here you will get data 
                }

                @Override
                public void onCancelled(@NonNull DatabaseError databaseError) {

                }
            });
