How to Get Download URLs from Firebase Storage After an Upload?

Obtaining Download URLs from Firebase Storage

Firebase Storage offers a convenient way to manage and share files in your Firebase project. Getting the download URL of an uploaded file is crucial for allowing users to access or share the file.

To retrieve the download URL from an upload task using Firebase Storage, avoid using taskSnapshot.getTask().getResult(). Instead, use the addOnSuccessListener method as demonstrated below:

uploadTask.addOnSuccessListener(new OnSuccessListener<uploadtask.tasksnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<uri>() {
            @Override
            public void onSuccess(Uri uri) {
                String url = uri.toString();

                // Use the download URL as needed
            }
        });
    }
});</uri></uploadtask.tasksnapshot>

Note that as of Firebase Storage version 16.0.1, the deprecated methods StorageMetadata.getDownloadUrl() and UploadTask.TaskSnapshot.getDownloadUrl() have been removed.

Important Note:

It's essential to keep in mind that both the success and failure listeners will only be invoked once the data is committed to or rejected by the Firebase servers. Therefore, they may not be triggered if your device cannot establish a connection with the Firebase Storage backend.
