Once you have a reference, you can download files from Cloud Storage by calling the getBytes or getStream. If you prefer to download the file with another library, you can get a download URL with getDownloadUrl. Download the file to a byte[] with the getBytes method.
This is the easiest way to download a file, but it must load the entire contents of your file into memory. If you request a file larger than your app's available memory, your app will crash.
