taskSnapshot.getDownloadUrl() is deprecated

Question

Until now, the way to get the url from file on Storage in Firebase, I used to do this taskSnapshot.getDownloadUrl, but nowadays is deprecated, which method I

Answer 1

Add the code below:

Task<Uri> downUrl=taskSnapshot.getMetadata().getReference().getDownloadUrl();
Log.i("url:",downUrl.getResult().toString());

Answer 2

Just use a Task instead of ref.putFile(uriImage) .addOnSuccessListener(new OnSuccessListener() Nowadays, firebase references suggest using Uploadtask objects

I've done it like this:

UploadTask uploadTask;
        uploadTask = storageReferenceProfilePic.putFile(uriProfileImage );

        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 storageReferenceProfilePic.getDownloadUrl();
            }
        }).addOnCompleteListener(new OnCompleteListener<Uri>() {
            @Override
            public void onComplete(@NonNull Task<Uri> task) {
                if (task.isSuccessful()) {
                    progressBarImageUploading.setVisibility(View.GONE);
                    Uri downloadUri = task.getResult();
                    profileImageUrl = downloadUri.toString();
                    ins.setText(profileImageUrl);
                } else {
                    // Handle failures
                    // ...
                }
            }
        });

Notice these lines in the above code:

Uri downloadUri = task.getResult();
profileImageUrl = downloadUri.toString();

Now profileImageUrl contains something like "http://adressofimage" which is the url to acess the image

Now you're free to use the String profileImageUrl however you wish. For e.g., load the url into an ImageView using Glide or Fresco libraries.

As Doug says, you will need to run it inside a Task

Here is a hint of how you need to implement it

final StorageReference ref = storageRef.child("your_REF");
uploadTask = ref.putFile(file);

    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 ref.getDownloadUrl();
        }
    }).addOnCompleteListener(new OnCompleteListener<Uri>() {
        @Override
        public void onComplete(@NonNull Task<Uri> task) {
            if (task.isSuccessful()) {
                Uri downloadUri = task.getResult();
                String downloadURL = downloadUri.toString();
            } else {
                // Handle failures
                // ...
            }
        }
    });

This code work for me.

You can try.
