Images, Caching and Sprites in Android -


i've got simple (so far) android app, shows friends on google map. think latitude.

the friends represented avatar pins, images of downloaded internet.

when "friend" added, fetch avatar in background thread. don't need download avatar again (i'll check updates during app start, not fussed right now). actual images come social network (facebook, google, twitter, gravatar, etc)

now, map view always displayed, images present. performing image manupilation, stacking, etc these avatars.

given above information, here questions:

  1. where should cache these images? looking @ docs, feel disk cache best option?
  2. should think creating image sprite? remember, these images don't live in apk/resources, dynamically fetched. perhaps create per-friend sprite different image sizes require?
  3. i have access server returns these images (right return url) - should enable server instead image processing/resizing etc based on requirements, or download original image , perform processing on client application?

you can use lazy loading dynamically download users images url , store in cache. believe link out in :

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
