This article is not about creating Java native methods to invoke C/C++ APIs. Instead, it aims to help developers build a JAR package containing a JNI shared library, made with Dynamsoft Barcode Reader, for Windows, Linux, and macOS from scratch. In this article, I will demonstrate how to create JNI...

Java Native Interface (JNI) is the glue between Java and native code such as C, C++, and assembly. With JNI, Java applications are capable of supporting platform-specific features. JNI enables developers to call low-level APIs (e.g. SQL, OpenGL etc.) to make Java application more powerful with higher performance. For example, we can...
