Java Question Seeking Assistance with Simple Compiler in B4A: Can Anyone Guide Me?

[carlos7000]

I tried using the Simple Compiler to create a library. When attempting to compile ed25519-java-0.3.0, I encountered the error:

I also tried compiling chilkat-9.5.0-android, but it gave the error:

I’m not sure if Simple Compiler is still a valid tool for library compilation.

The source code of ed25519-java-0.3.0 can be found in https://github.com/str4d/ed25519-java/releases/tag/v0.3.0
The source code of chilkat-9.5.0-android can be found in https://www.chilkatsoft.com/chilkatAndroid.asp

Do not use Java 14 for compilation

I also recommend you ask this question in the corresponding forum.

I suggest you try to compile the source code that is included inside the SLC zip

Which version of Java should I use?

 

[Mariano Ismael Castro]

According to Erel
You should use Java 8 with SLC (at least when generating the XML).

Hi Mariano.

Attempt to compile: ed25519-java-0.3.0

Attempt to compile chilkat-9.5.0-android

Completed Successfully!

But when trying to use the library in B4A:

Seems like you have a library enabled that already defines com.chilkatsoft.chilkatJNI.ckscminidriver_lasterrorhtml.....

It's strange. Because Chilkat is the only bookstore

 

[Johan Schoeman]

In the -b4aignore field of SLC - put com. in the field so that it ignores classes starting with com and while is creates the accompanying XML file. Maybe it helps

I asked Copilot about the error: package sun.security.x509 does not exist import sun.security.x509.x509Key

Copilot responded:

Try compiling ED25519-java-0.3.0 and the new error is

Try -source 1.6 -target 1.7

I tried modifying the pom.xml as suggested by Copilot

Nothing works yet.

 

[Johan Schoeman]

-ba4ignore must be the start of a package name. Your packages all start with COM. So, try and put COM. in lower case letters into -b4aignore (com.)

 

[Johan Schoeman]

Have you written a wrapper for the project? If so, what is the package name of your wrapper?

See here. Read the thread.

Chilkat Rsa Library

Hello I'd created a library from the source code attached in the zip file. ....I can't call the library; But appears in the referenced libraries without the version info. I don't know where to put the version info. But I edit the chilkat.java and put the following package com.chilkatsoft...

www.b4x.com

His wrapper package name clashed with the package name of the chilkat java project

I made a file similar to the one in the FlurryAgentWrapper example and copied it to libs but it didn't work

I'm going to read it. I'm going to see if I can do something

What is the package name of your wrapper? Have you tried to compile is when you enter
com.
to the -b4aignore field of SLC?

 

[Johan Schoeman]

I have just built the jar and XML with a dummy wrapper and added it to a B4A project without a problem.

This is the wrapper I wrote. My knowledge of Java is very little:

package mi.ed25519;

import com.chilkatsoft.CkEd25519;

public class Ed25519Wrapper {
    private CkEd25519 ed25519;

    public Ed25519Wrapper() {
        ed25519 = new CkEd25519();
    }

    public String sign(String privateKey, String message) {
        return ed25519.signStringENC(privateKey, message);
    }
}

Place the file in Libs as it says in https://www.b4x.com/android/forum/t...mpiler-build-libraries-without-eclipse.29918/

See the folder structure in the attached. I have removed the .so files from their folder else too big to upload. Put the .so files back in their folders before trying to compile with SLC

I see no class in the java project with a name of CkEd25519.......?

import com.chilkatsoft.CkEd25519;

Where did you get this class from?
