how to stream a mp3 audio from firebase storage

Question

I'm developing an app that will stream mp3 file stored in firebase storage. Nearly I'm having 100 songs like song1,song2,song3..... if a song is selected I have to stream that particular song without downloading. In such case I need to write plenty of code because for each song I have to mention the firebase storage url. the url would be like

https://firebasestorage.googleapis.com/......song1.mp3?alt=media&token=8a8a0593-e8bb-40c7-87e0-814d9c8342f3

For each song the alt=media&token= part of the url varies, so I have to mention the unique url for all songs. But here I need some simplified coding to play the songs by mentioning its name alone from firebase storage.

Please suggest a way to stream the audio file by using its name alone that is stored in firebase storage.

Answer 1

You have two choices if you want to get files out of a Firebase Storage bucket.

1. Use the full download url that you can get from a Storage Reference that points to the file path in your bucket.
2. Use a download task (Android or iOS) to fetch the data from the file.

You can't get the file data any other way from within a mobile app. Firebase Storage doesn't support special media streaming protocols, such as RTSP.

Answer 2

I did it using downloadUrl.

val storage = FirebaseStorage.getInstance()
storage.reference.child("songs/song1.mp3").downloadUrl.addOnSuccessListener({
    val mediaPlayer = MediaPlayer()
    mediaPlayer.setDataSource(it.toString())
    mediaPlayer.setOnPreparedListener { player ->
        player.start()
    }
    mediaPlayer.prepareAsync()
})
