When developing a phone app, your app may need to transfer files to or from a remote server. In some cases, your app may not be able to continue without having a certain file on hand. But in other cases, the file may not be required immediately and can be downloaded asynchronously using a background file transfer. Candidates for these kinds of file transfers include downloading large files (for example, music and video files) or backing up an app’s local database.
