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:
Is there a Java SDK for AArch64? If not, can I compile it myself for my architecture?
Supporting Arm based Linux isn't currently part of the product, but for Java we have a public beta which does allow you to try this out.
I have also written a couple of blog posts on the subject showing possible use-cases for the beta.
You should however be aware that we are deprecating the Maps SDK for Java so whilst the beta would allow you to try out the API, longer term we will be proving support for Arm Linux using the Qt Maps SDK.
I'd be very interested to hear more about what you are wanting to do using the Raspberry Pi.
Does this help?
