按照这个链接- https://firebase.google.com/docs/storage/android/download-files#download_data_via_url

storageRef.child("users/me/profile.png").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
    @Override
    public void onSuccess(Uri uri) {
        // Got the download URL for 'users/me/profile.png'
        Uri downloadUri = taskSnapshot.getMetadata().getDownloadUrl();
        generatedFilePath = downloadUri.toString(); /// The string(file link) that you need
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // Handle any errors
    }
});
