This Java API is a data encapsulation of the C++ sample code with JNI, and is therefore slightly different from that of the C++ API in structure. The Agora SDK (sample code shared by C++ and Java) implements the C++ recording APIs and callbacks, goes through data encapsulation in the JNI layer, and then works as the Java interface and class of the Native SDK through the JNI proxy.

The RecordingSDK class provides the main methods that can be invoked by your application.
The RecordingEventHandler class enables callbacks to your application.
