Android Question Firebase Storage File List

[mw71]

how i can get a Filelist from a directory?

Erel means:

There is no "list" API in Firebase Storage. You can create a text file that lists the other file. You will need to update it each time that you add a file.

Any solution to generate the File "automatic" at the Server or other solution for the Problem?

thanks

No. You will need to do it from the client. Download the current list file, update it and upload the new file.

Hi,
I was wondering if there's any update on this.
Can one list files in firebase storage, 5 years later?

There is a way to list files using the Cloud Storage List API, but I don't know if it's implemented in any B4X library that supports Firebase Storage.

here's the Java code from that page...

  public void listAllFiles() {
        FirebaseStorage storage = FirebaseStorage.getInstance();
        // [START storage_list_all]
        StorageReference listRef = storage.getReference().child("files/uid");

        listRef.listAll()
                .addOnSuccessListener(new OnSuccessListener<ListResult>() {
                    @Override
                    public void onSuccess(ListResult listResult) {
                        for (StorageReference prefix : listResult.getPrefixes()) {
                            // All the prefixes under listRef.
                            // You may call listAll() recursively on them.
                        }

                        for (StorageReference item : listResult.getItems()) {
                            // All the items under listRef.
                        }
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        // Uh-oh, an error occurred!
                    }
                });
        // [END storage_list_all]
    }

now, how we make it b4x alike?

Well if it's not implemented in a B4A library I guess you could try inline Java - but it's not really my thing, so I couldn't tell you how.

As of May 2019, version 6.1.0 of the Firebase SDK for Cloud Storage now supports listing all objects from a bucket. You simply need to call listAll() in a Reference:

I guess that the firebase storage lib needs an update to make this work :

Dim storage As FirebaseStorage = CreateFirebaseStorage
Dim PubList() as list = storage.ListAll("/public/")


Sub CreateFirebaseStorage As FirebaseStorage
    Dim storage As FirebaseStorage
    storage.Initialize("storage", bucket)
    Return storage
End Sub

How do I #if java this ?
