代码：

void exoPlayerNotification(Context context, SimpleExoPlayer exoPlayer, String title) {
    PlayerNotificationManager mPlayerNotificationManager = PlayerNotificationManager.createWithNotificationChannel(
            context,
            "PRIMARY_CHANNEL_ID",
            R.string.plaza,
            555,
            new PlayerNotificationManager.MediaDescriptionAdapter() {

                    Intent intent = new Intent(service, MainActivity.class);
                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |

                }

                @Override

            }
    );

    mPlayerNotificationManager.setSmallIcon(R.drawable.smallwidth);
    mPlayerNotificationManager.setNotificationListener(new PlayerNotificationManager.NotificationListener() {
        @Override
        public void onNotificationStarted(int notificationId, Notification notification) {
            service.startForeground(notificationId, notification);
        }

        @Override
        public void onNotificationCancelled(int notificationId) {
            service.stopSelf();
            cancelNotify();
        }
    });
    mPlayerNotificationManager.setPlayer(exoPlayer);
}    

任何人都可以帮助我解决此问题
