Hey guys,
Since I still haven't figured out how to do it via the API, here a the
quick and dirty workaround which transforms the link you get from the
client API to the link you get when you click "Download Image" in the
PWA interface. It uses 'd' imgmax-parameter described in the above
post in link [2].
PhotoEntry photo = ...
String resizedURL = photo.getMediaContents().get(0).getUrl();
int slashIndex = resizedURL.lastIndexOf("/");
URL originalURL = new URL(resizedURL.substring(0, slashIndex)
+ "/d" + resizedURL.substring(slashIndex));
InputStream is = originalURL.openStream();
Hope this helps some of you guys.
@Google: Could you add documentation for this in the client API docs?
Regards,
Philipp
