アプリでFirebaseから動画を取り込む方法は？

Question

firebaseのストレージに動画を追加し、カードビューのリサイクラービューですべてのアップロード動画を取得したいと考えています。

これに関する参考資料またはソースコードを提供してください。

firebaseで動画をアップロードしようとしていますが、正常にアップロードされましたが、取得できません。

ありがとうございます。

、それはかなり簡単ですファイルをダウンロードする：

StorageReference videoRef = storageRef.child("videos/myvideo.mp4"); 

final long ONE_MEGABYTE = 1024 * 1024; 
videoRef.getBytes(ONE_MEGABYTE).addOnSuccessListener(new OnSuccessListener<byte[]>() { 
    @Override 
    public void onSuccess(byte[] bytes) { 
     // Transform bytes to a video, play 
    } 
}).addOnFailureListener(new OnFailureListener() { 
    @Override 
    public void onFailure(@NonNull Exception exception) { 
     // Handle any errors 
    } 
});
