Android Question AAR file usage

[Asoka]

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!

Can I import directly as AdditionalJar

yes

and find the Classes path?

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:

#BridgeLogger: True
#AdditionalJar: eftterminalzvt-debug.aar

And after:

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:

Dim M As JavaObject
M.InitializeContext
OBJMonera = M.InitializeStatic("hu.monera.eftterminalzvt.EftTerminalZVT")
Log("MoneraOBJ Init: " & OBJMonera.IsInitialized)

in file: eftterminalzvt-debug.aar (if I see unzipped) there is a file named "classes.jar".
do I have to do something with it?

 

[DonManfred]

do I have to do something with it?

Only if you write a wrapper for this AAR using java.

You do not need it when using javaobject.
