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.
RecordingSDK Class
