Third Party Java Libraries

Can Lazarus for Android access Third Party Java Libraries?
Needing to access Bar Code Reading hardware. Have Java SDK for it.

Yes.

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

Great News, are there any online examples for this?
Also what is the difference between Android and Android-JVM?

AFAIR LAMW has a tool for generating Pascal unit from Java classes, but I'm not sure. I haven't coded Android in a long time.

The former targets ARM natively (will only run on Android of the same architecture), the latter targets... well... JVM, just like what a Java compiler will produce (it will run on any Android regardless of architecture).

Does this mean if I compile an Android APP using Android Oreo NDK and SDK in LazAndroid, it can only work in Oreo? Oreo = Android 8.0.0

LAMW (Lazarus Android Module Wizard) is one of the possible way to create Android apps using Lazarus.

There are several other ways to create Android apps using Lazarus/FPC:

Android version isn't related with any of the above. You define that in the manifest (target SDK version and minimum SDK version).
