[B4X] KVS - KeyValueStore library

A key / value persistent store. The data is serialized using B4XSerializator and is stored in an internal database. The database can be shared between B4A, B4i and B4J. Using KVS is similar to using a Map. You initialize it once and then you can put or get items with Put, Get or GetDefault...

This was the avenue I ended up taking.
And I was able to get it to work.

Thank you so much for your help and thank you to everyone else who also shared their methods.

Based on your question in the first post, it seems the simplest way is to save the string to a file and retrieve it
when needed. KeyValueStore2 is good, but an overkill in this case:

Dim s As String = "B4X Community"
    File.WriteString(File.DirInternal,"myfile.txt", s)
    
    Dim savedvar As String = File.ReadString(File.DirInternal, "myfile.txt")
    Log(savedvar)  'displays: B4X Community
