If it only does what is shown in the video, it would be easier to create a class / custom view in B4a to do the same.

I want to use it as an example for other libraries

like this

Library (JAR) interface using inline Java code and "direct calling"

Attached project demonstrates two ways to interface with a JAR file: 1. Using the JavaObject run method "directly" 2. Making use of inline Java code For method 1 you need to make use of #AdditionalJar: fiddleAround in the B4A code (see the code) For method 2 you need to make use of import...

is it possible to convert java file to jar file without wrapp?

[Tool] Simple Library Compiler - Build libraries without Eclipse

The purpose of Simple Library Compiler (SLC) is to make it easier to build libraries. SLC is responsible for taking the Java source code files and generating the Jar and XML files. As I see it, it can be useful in two cases: - Creating wrappers for 3rd party SDKs. - Modifying and extending...

LGenerator - Library Generator

LGenerator is another python script wrapped in pyInstaller. What it does? It generates an xml/jar file for a wrapped library. It is similar to SLC (SLC never worked for me). It is the same as Ecplise's 2 step (Generate Javadoc + Export JAR). What it doesnt do? Automatically create libraries...

is it possible to convert java file to jar file without wrapp?

Yes in most cases its possible to use jar file without wrapper.

1. Copy that jar and its dependencies (if applicable) to additional library folder.
2. Include those using #AdditionalJar

#AdditionalJar: yourlib.jar

3. Add #if JAVA at the bottom of the activity in which you want to use that library functions.
4. Inside that #if import relevant class from that library
5. Then write a function to use that library functions as you want.

#if JAVA
import your.library.classname;

Public void testfunction(){
   YourLibClass var1 = new YourLibClass(); //just an example
}
#End if

6. Call that function from B4A code using JavaObject.

Dim jo as JavaObject=Me
jo.RunMethod("testfunction",null)
