H A Davsession-access-scene.md250 （2）如果应用设置完整歌曲时长，但需要系统支持试听片段，也可以在播放时上报起始进度position，当收到的seek指令超过试听片段时，上报试听截止position，系统播控的进度会跟随回弹。
282 | seek | 跳转命令。 |
437 应用如果支持进度显示，进一步也可以支持进度控制。应用需要响应seek的控制命令，那么当用户在播控中心的界面上进行拖动操作时，应用就会收到对应的回调。参考实现：
448 session.on('seek', (position: number) => {
449 console.info(`on seek , the time is ${JSON.stringify(position)}`);
451 // 由于应用内seek可能会触发较长的缓冲等待，可以先把状态设置为 Buffering
463 // 应用响应seek命令，使用应用内播放器完成seek实现
