JsonDbOpensocialService->getActivities always returns all activities regardless of startindex/count.
Fixed this issue and added an unittest to reproduce.
Patch has been applied, thanks!
ps, I think we also have a 0.9 tracking bug for it some where (every 0.9 todo item has a issue filed for both the java and shindig components). Could you add a comment to it that support for activity paging has been completed in the php version? (that way we know we can close it once the java version also implemented it)
