Extension

This interface is used by AAP Service extensions that will be initialized at onCreate(). Not to be confused with AAP extension in the native (audio plugin) API context (get_extension()).

By registering this extension as a <meta-data> element in AndroidManifest.xml, whose android:name is org.androidaudioplugin.AudioPluginService#Extensions, the implementation class that is specified in the android:value attribute of the <meta-data> element will be instantiated and those members are invoked, wherever appropriate.
