External references, such as a standards document, or specification? http://stackoverflow.com/questions/9941378/how-to-download-a-large-file-using-google-api-java-client-on-android http://javadoc.google-http-java-client.googlecode.com/hg/1.8.3-beta/com/google/api/client/http/HttpResponse.html Java environments (e.g. Java 6, Android 2.3, App Engine, or All)? All Please describe the feature requested. Here's an idea: suppose you want to just download the content of a response into a file, e.g. if you are downloading an image. A good way to do it is to use AbstractInputStreamContent.copy as in this example:

HttpTransport transport = new NetHttpTransport();
HttpRequestFactory requestFactory = transport.createRequestFactory();
HttpRequest request =
    requestFactory.buildGetRequest(new GenericUrl(
        " https://www.google.com/images/srpr/logo3w.png")); OutputStream outputStream =
    new FileOutputStream(new File("/tmp/logo3w.png"));
HttpResponse response = request.execute();
InputStream inputStream = response.getContent();
AbstractInputStreamContent.copy(inputStream, outputStream, true);

Unfortunately, AbstractInputStreamContent.copy is hard to discover. Perhaps we can make it easier to find by adding an HttpResponse.download(OutputStream) method, so now the last 2 lines would now be:

response.download(outputStream);

We could also potentially add something similar in JsonHttpRequest and JsonHttpClient.
