UploadTask.TaskSnapshot doesn't have getDownloadUrl() method

I’m following a tutorial teaching how to upload images to Firebase. At certain moment the instructor will write the code to get the download URL after uploading by using getDownloadUrl() method from UploadTask.TaskSnapshot, but for me, this method doesn’t exist.

Based on another code I found, I tried the following:

OnSuccessListener<UploadTask.TaskSnapshot> upload = new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        ChatroomMessage message = new ChatroomMessage(null, mUsername, taskSnapshot.getDownloadUrl());
        mMessagesDatabaseReference.push().setValue(message);
    }
};

Because it is similar to what’s shown in the documentation, but I didn’t understand it very well. How to implement it?

Yes they deprecated and then removed that method. I use the following code, similar to what is written in the docs.

photoStorageReference.putFile(selectedImageUri).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();
        }
        return photoStorageReference.getDownloadUrl();
    }
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
        if (task.isSuccessful()) {
            Uri downloadUri = task.getResult();
            FriendlyMessage friendlyMessage = new FriendlyMessage(null, mUsername, downloadUri.toString());
            mMessagesDatabaseReference.push().setValue(friendlyMessage);
        } else {
            Toast.makeText(MainActivity.this, "upload failed: " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
        }
    }
});

taskSnapshot.getStorage().getDownloadUrl().toString()

@DevRyz3n running this command would raise FileNotFoundException as the returned value is not the download url for file. Instead try this code where I have created a Task object to perform getDownloadUrl() task, waited for its completion in the main thread and then obtained the URL through getResult() function.

@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
     Task<Uri> urlTask = taskSnapshot.getStorage().getDownloadUrl();
     while (!urlTask.isSuccessful());
     Uri downloadUrl = urlTask.getResult();
     FriendlyMessage friendlyMessage = new FriendlyMessage(null, mUsername, downloadUrl.toString());
     mDatabaseReference.push().setValue(friendlyMessage);
}
