Please suggest me a caching technique where I can cache the list of items downloaded when network is on and read from cache in the absence of network. I need to have the limit for number of items stored in cache (each item avg size will be 10kb) . It will be help full if the caching technique used will handle the deleting mechanism.
I don't know exactly what you're storing or how much sorting you need, but if it's simple id = article to recall the basic data I'd say just use text files. Sometime simple works.
Alternatively, in the same vein you could use JSON files
Contents of JSON could contain values for title, body, etc (if needed).
If you need to sort or search them directly I'd say SQLite probably.
