@oday but from the remite foo list screen I already fetched the data, requesting from network again feels wasteful, so yea maybe as to emulate database, keep it in a hashmap as @yshrsmz said but then, when to invalidate this hashmap? and also process death, youd loose the object, so youd need to rerequest the network..

if you need to consider process death, then you should use database.

saving it ti databse just because of process death -- and deleting the item every screen back press feels waste ful?
