JNI (Java Native Interface)

In computing, the Java Native Interface (JNI) is a programming framework that enables Java code running in a Java Virtual Machine (JVM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.

Android Callable Wrappers (ACW)

Android callable wrappers are a JNI bridge that are used whenver the Android runtime needs to invoke managed code.

Managed Callable Wrappers (MCW)

Managed callable wrappers are a JNI bridge that are used whenever managed code needs to invoke Android code and provide support for overriding virtual methods and implementing Java interfaces.

Embedded vs. Non-Embedded

When using a Build Action such as EmbeddedJar or EmbeddedReferenceJar, it will embed the respective library into the .apk so it will be available at runtime.

Otherwise it is expected that either the Device or the application will provide the .jar at runtime. (I.E. It is already loaded on device or will be provided via a download/etc)

Reference vs. Non-Reference

When using a Build Action such as ReferenceJar or EmbeddedReferenceJar, it will not generate Manage Callable Wrappers(ACW) and will not be exposed to the client.

Java is not the same as C#

Because of this limitation, you will need to be aware of the respective generated C# code as there might be certain things that the languages handle differently.

EX: Java -> C#

• get/set methods -> properties
• fields -> properties
• listeners -> events
• static nested class -> nested class
• inner class -> nested class with an instance constructor
