Unable to play audio in firebase storage sent from android app

I am using firebase storage to upload audio from my android app and then download and play in my app. The audio file gets uploaded but when I play it from firebase storage,it comes in a video format like image below and does not play the audio. I am also setting metadata as audio/mp3 for it.

I tried to search about the same in firebase documentation and google but could not get my issue resolved.

video format 

Uri file = Uri.fromFile(new File(fileName));
 //filename is audio stored in my phone's local storage.

StorageMetadata metadata = new StorageMetadata.Builder()
            .setContentType("audio/mp3")
            .build();

// Upload the file and metadata


 UploadTask uploadTask = storageReference.child("audio/audio.mp3").putFile(file, metadata);

uploadTask.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
        double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
    }
}).addOnPausedListener(new OnPausedListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onPaused(UploadTask.TaskSnapshot taskSnapshot) {
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // Handle unsuccessful uploads
    }
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        // Handle successful uploads on complete
        // ...
        Task<Uri> uri = taskSnapshot.getStorage().getDownloadUrl();
        while(!uri.isComplete());
        Uri url = uri.getResult();

        Toast.makeText(MainActivity.this, "Upload Success, download URL " +
                url.toString(), Toast.LENGTH_LONG).show();
    }
});

Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
    @Override
    public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
        if (!task.isSuccessful()) {
            throw task.getException();
        }

        // Continue with the task to get the download URL
        return storageReference.getDownloadUrl();

    }
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
        if (task.isSuccessful()) {
            Uri downloadUri = task.getResult();

        } else {
            // Handle failures
            // ...
        }
    }
});

I want the audio to be saved properly in firebase storage and then stream it in my app. Any help will be appreciated. Thank you!

Your problem could have been caused by MediaRecorder. I have figured out that the output format should be set to AAC. Then the browser will be able to play it. I experienced this problem when I was trying to use React JS to play audio captured by MediaRecorder in Android, and I tried various formats (.3gp, .mp4, .wav), but this is the only one that worked. I suspect there are other ones, too.

So:

mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.AAC_ADTS);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

Try like this, 


metadata = new StorageMetadata.Builder()
        .setContentType("audio/mpeg")
        .build();

uploadTask = storageRef.child("audio/"+file.getLastPathSegment()).putFile(file,metadata);
