Question

I am trying to download video file from firebase to local storage here is the code that i have used to download the video file

private fun downloadVideo(videoModel: VideoModel) {

    val videoUrl = videoModel.url
    val storageRef = FirebaseStorage.getInstance().getReference(videoUrl)
    storageRef.metadata
        .addOnSuccessListener { storageMeta ->
            val fileName = storageMeta.name
            val fileType = storageMeta.contentType
            val fileDiroctory = Environment.DIRECTORY_DOWNLOADS
            val downloadManager = context.getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager
            val uri = Uri.parse(videoUrl)
            val request = DownloadManager.Request(uri)
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
            request.setDestinationInExternalPublicDir(fileDiroctory,"$fileName.mp4")
            downloadManager.enqueue(request)
        }
        .addOnFailureListener {
            Toast.makeText(context,"Please try again",Toast.LENGTH_SHORT).show()

I am calling the download function from viewholder recyclerview adapter

 override fun onBindViewHolder(holder: VideoHolder, position: Int) {
    val videoUrl = videoList[position]
    videoList[position]?.let { holder.setVideoData(it) }
    holder.downloadVideo.setOnClickListener {
        if (videoUrl != null) {
            downloadVideo(videoUrl)
        }
    }

And in firebase the video is uploaded just using the url id

data class VideoModel(
var url:String = ""

)

The actual video's are saved in firebase storage

And and i am getting this videos to my application from firebase firestore Database

Answer 1

To get a StorageReference based on download URL for the video, you should use refererenceFromUrl instead of getReference.

final storageRef = FirebaseStorage.instance.refererenceFromUrl(videoUrl);
