如何解决适用于 Android 的 Brightcove Native SDK 提供 NoClassDefFoundError

我的 Android 应用程序在使用适用于 Android 的 Brightcove Native SDK 时崩溃。 Android Studio 日志显示-

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/android/exoplayer2/drm/DefaultDrmSessionEventListener; 

活动类-

public class SetActivity extends BrightcovePlayer {

@Override
protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_set);
    BrightcoveExoPlayerVideoView brightcoveVideoView = (BrightcoveExoPlayerVideoView) findViewById(R.id.brightcove_video_view);
    super.onCreate(savedInstanceState);
    
    // Define a video from a Remote Server
    Video video = Video.createVideo("https://learning-services-media.brightcove.com/videos/hls/greatblueheron/greatblueheron.m3u8",DeliveryType.HLS);

    // Load a remote poster image
    try {
        java.net.URI myposterImage = new java.net.URI("https://solutions.brightcove.com/bcls/assets/images/Great-Blue-heron.png");
        video.getProperties().put(Video.Fields.STILL_IMAGE_URI,myposterImage);
    } catch (URISyntaxException e) {
        e.printstacktrace();
    }

    // Add video to the view
    brightcoveVideoView.add(video);
    // Start video playback
    brightcoveVideoView.start();


}

}
