I want to delete the data from app using firebase

Question

There is some data in my firebase store and this data is being propagated to my app but after some time I want to remove that data from my app (when the data is too old). I want to know how can I do this, when I delete data from firebase, the data from app should be deleted.

this.mfirebasefirestore= FirebaseFirestore.getInstance();
mfirebasefirestore.collection("Users").addSnapshotListener(new EventListener<QuerySnapshot>() {
    @Override
    public void onEvent(@Nullable QuerySnapshot queryDocumentSnapshots,
                        @Nullable FirebaseFirestoreException e) {
        if(e!=null){
            Log.d(TAG,"Error");
            return;
        }
        assert queryDocumentSnapshots != null;
        for(DocumentChange doc:queryDocumentSnapshots.getDocumentChanges()){
            if(doc.getType()==DocumentChange.Type.ADDED){
                Users users=doc.getDocument().toObject(Users.class);
                usersList.add(users);
                usersListAdapter.notifyDataSetChanged();
            }
        }
    }
});

I think the best way is to write Cloud Function which after some time will be removing old data.

Or you could do something like this: How to delete firebase data after "n" days

This solution that I pasted above is about deleting data from firebase. Try solution of @Frank van Puffelen, it is deleting data from firebase older than 30 days. – Panicum Mar 19 '19 at 22:09
