How to Create Native Binaries for Your Java App

How to create native binaries for your Java app?

To make a native binary for Windows, you would use a tool like Launch4J. On OSX you could use JarBundler. Minecraft simply distributes the jar file for Linux. I'm not aware of a native binary packager for Linux.

You could also compile your Java code via GCJ but that's probably not what you want, as there are limitations and compatibility concerns there. The native bundlers like Launch4j and JarBundler simply wrap your jar file and use a real JRE to execute it.

As for integrating with NetBeans or Eclipse, you'll probably have to write your own ant build file, especially since the solution varies from one platform to the next.

Unable to execute native binaries file in MacOS?

The most simple way would be to either open a terminal and manually running the binary, like so:

./<name-of-file>

This would only work if you are running the file in a user who has execution privileges on that file. if you run into trouble with priviliges, that's where I would use chmod.
If you need any more specific help, I would recommend posting the link to that GitHub repo for us to look at, and telling us what is it that it should do.

Android: Why doesn't native binary have access to the internet, while my Android application does

As pointed out in the comments, I made an embarrassing typo in the C code,..

/system/bin/ping -c nu.nl

should have been

/system/bin/ping -c 1 nu.nl

(I did have connection problems as pointed out by a linked in curl library, but now curl isn't complaining about that anymore)

Android: Execute binary from application

I found the difference and it has nothing to do with native code...

These applications use targetSdkVersion 28 or lower, where the execution of binaries was still allowed. This means that binaries can be executed with the Runtime object as well as with native code in this SDK version.

The applications can still be installed on newer Android versions.

So I solved my issue by setting the targetSdkVersion to 28.

Code in C# and build into cross platform binaries? (iOS and Android)

You could have a look at MonoCross. But Xamarin's offerings really are second to none if you want to write Android/iOS apps in C#.
