How do you connect to location beacon Storage

I’m trying to build a simple activity that Writes to the EEPROM storage and Reads it back. There doesn’t seem to be much info available for beginners on the topic. I’ve found one post from December 19th in the change log describing how to build the HashMap and Write to storage but I need more info to make it work. Need some help getting from “onCreate” to “Map”. I know its a lot to ask but I’m stuck.
