MIT AppInventor: How to handle a large list?

I'm currently working on a MAC Address Lookup Module. I want it to be offline. I have a large amount of text (OUI Database, each item in a new line) and I want to perform a search in it. However, I can't find a way to import it into a variable. Things that I've tried:

  • Handle the whole database as a file and read it (The app hangs on or I run out of RAM)
  • Set a list variable internally to the comma-separated version of the database (The app freezes)

Any ideas?

Solution

  • Looking at Bloom filters might give you some ideas on how to rework your problem. This is a space-efficient data structure and can tell you if something is definitely not part of something and if something probably is in it.
