Java SDK support for aarch64 on Linux

Question

I am trying to integrate the ArcGIS Runtime SDK for Java (v. 200.0) into an application running on Ubuntu 20.04 ARM (running on NVIDA Orin).  The platform is aarch64.  This architecture is available for Mac M1, but the Linux (LX64) version only supports x86_64.  Is there any plans to create an arm version of the LX64 libraries?  The embedded beta for QT includes the runtime.so for ARM but of course, not the Java runtime so.

Hi!

I am using ArcGIS Maps SDK for Java 200.4.0 and am running the JAR on a Raspberry Pi 4 Model B (AArch64) with Ubuntu 22.04. When referencing the "SpatialReferences" class, the following exception is thrown:* java.lang.NoClassDefFoundError: Could not initialize class com.esri.arcgisruntime.geometry.SpatialReferences
* Exception java.lang.UnsatisfiedLinkError: /root/.arcgis/200.4.0/jniLibs/LX64/libruntimecore.so: /root/.arcgis/200.4.0/jniLibs/LX64/libruntimecore.so: cannot open shared object file: No such file or directory (Possible cause: can't load AMD 64 .so on a AARCH64 platform)

Any updates on porting the Java SDK to AArch64?

@seanlwl I've sent you a DM with my email address.  I'd like to find out more about your ARM Linux requirement.

@seanlwl as a development project I have had this working on a ARM Linux box and even had it working on a Raspberry Pi 4 which was quite exciting.

As for releasing this officially it needs customer demand so we can prioritise this with other development projects.  Are you in direct contact with anyone at Esri about his already?  Maybe you could DM me so we can talk about what you are wanting this for.
