Hi Friends!

I've an "AAR" file to manage a HW in my planned project (kios terminal with POS payment).
The file is the manufacturer's LIB to (connect, pay, ... etc) POS device.

What is the best way to use this library in B4A(v9.50):
Can I import directly as AdditionalJar and find the Classes path?
Do I have convert (or rename) it to jar file?
Pls Help!

Thank you!

No.

See this Tutorial. Note that you need some java knowledge do use it.

Accessing third party Jar with #Additionaljar and JavaObject - Picasso

The #AdditionalJar module attribute (introduced in B4A v3.80) allows us to reference external jars. With the help of JavaObject it is now possible to integrate third party jars without a wrapper. This solution is good for "simple" libraries. If the API is complicated with many interfaces then...

OK Thank You!

So Can I do This:

To add LIB:: 
#BridgeLogger: True
#AdditionalJar: eftterminalzvt-debug.aar

And after:
To Create Object from:: 
Dim OBJMonera As JavaObject
OBJMonera = M.InitializeStatic("hu.monera.eftterminalzvt.EftTerminalZVT")

And Call functions (if I found funct. names) with JavaObject.RunMethod?

I cant answer this question. You need to consult their documentation.

Note that you should only use InitializeStatic on static Classes.

Usually you need to use InitializeNewInstance

InitializeNewInstance not working, but:
OBJMonera (is a Process_Globals variable) IsInitialized: True: 
Dim M As JavaObject
M.InitializeContext
OBJMonera = M.InitializeStatic("hu.monera.eftterminalzvt.EftTerminalZVT")
Log("MoneraOBJ Init: " & OBJMonera.IsInitialized)
