is it possible to save images from the MediaStore, based on a certain user action, in a key/value pair using Hashmap. what i mean is, if the app gets restarted, does the Hashmap retain the contents or would i have to perform the action again.
what other solutions can i use to save the images for fast retrieval?.. shared Preferences or sqlite database, but i am assuming the latter might just be a waste.
Hope i am clear on this. Thank you.

A HashMap would get destroyed when your application is destroyed & restarted.
One option would be to use your applications cache directory and define a mapping between your key and the filename in the cache folder.
