Mastering Firebase for Android Development

Retrieving File Metadata

Firebase storage can store file content and file metadata, which contains properties such as the content type and timestamp of the file created in Firebase storage. Using getMetadata() on the storage reference instance, we can retrieve the metadata of the file:

StorageReference storageRef = storage.getReference();StorageReference forestRef = storageRef.child("images/forest.jpg");forestRef.getMetadata().addOnSuccessListener(new OnSuccessListener<StorageMetadata>() {    @Override    public void onSuccess(StorageMetadata storageMetadata) {    }}).addOnFailureListener(new OnFailureListener() {    @Override    public void onFailure(@NonNull Exception exception) {    }});

This code retrieves the metadata of the file with success and failure ...
