[quote]# Downloading the Manifest for a mobile app i would assume you should download re-usable data to save requests and thus bandwidth. i would let it compare the version (online/ downloaded) and if it needs to download do this in an asyncTask. how is this properly achieved? any libraries you would propose for this?[/quote]For checking for a new version you could: a) on starting the app or at some interval, make a HTTP request to "www.bungie.net/platform/destiny/manifest" b) compare the version in the response with the version of the manifest you have locally (if one at all) c) retrieve the manifest file - the one you will probably want/need is Response.mobileWorldContentPaths.en d) Unzip the file (as it is compressed) and you will have an SQLite database with the content you can then query I have the equivalent of that in PHP at the moment which you can probably translate to Java. Let me know if anything's not clear.

You'll need to modify them by hand.
