I don't seem to be able to download libraries for B4J (such as encryption, etc.). The site says I do not have permission and they seem to mostly be in the B4A "section".
Do I need to purchase one of the other products to get this access?
Not necessarily a problem (even though I have no need for the others) seeing as B4j is an obscene bargain at "free".
You should be able to download B4J libraries. The Encryption library (as well as some of the other libraries used in B4J) is actually a B4A library. These libraries are restricted to licensed customers.
Ok, so I need to buy B4A to use that sample project. Is there any particular version I need to buy? Can I just by he $59 version? As I say, I have no use for Android dev. so I would be purchasing just for the external library to use in B4J.
