When you download a large media file from a server, useresumable media download to download the file chunk by chunk. The Google APIgenerated libraries contain convenience methods for interacting with resumablemedia download, which was introduced in the1.9.0-betaversion of the Google API Client Library for Java.
The resumable media download protocol is similar to the resumable media uploadprotocol, which is described in theGoogle Drive API documentation.

Implementation details
The main classes of interest are MediaHttpDownloader and MediaHttpDownloaderProgressListener.Media content is downloaded in chunks, and chunk size is configurable. If aserver error is encountered in a request, then the request is retried.
If methods in the service-specific generated libraries support download in theDiscovery document, then aconvenient download method is created for these methods that takes in anOutputStream.(For more about using media download with the Google APIs Discovery Service, seeMedia download.)
For example:
You can also use this feature without service-specific generated libraries.Here is an example:
Direct media download
Resumable media download is enabled by default, but you can disable it and usedirect media download instead, for example if you are downloading a small file.Direct media download was introduced in the1.9.0-betaversion of the Google API Client Library for Java.
Direct media download downloads the whole media content in one HTTP request, asopposed to the resumable media download protocol, which can download in multiplerequests. Doing a direct download reduces the number of HTTP requests butincreases the chance of failures (such as connection failures) that can happenwith large downloads.
