每次我暂停我的活动（实际上是片段）以转到另一个应用程序时，在使用 onResume 返回时，我尝试恢复视频播放，但它不播放：我得到一个空白屏幕。经过调查，我在 Logcat 中看到以下内容
E/BufferQueueProducer: [unnamed-23827-0] queueBuffer: BufferQueue has been abandoned
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/BufferQueueProducer: [unnamed-23827-0] connect(P): BufferQueue has been abandoned
这是我在简历中调用的代码
player.seekTo(mVideoSeekPosition);
player.start();
仅供参考：我一直在尝试将此答案应用于我的案例，但我不能：当BufferQueue被废弃时我该怎么办？
UPDATE
我努力独自前行，但我仍然崩溃。所以我发布整个代码以寻求帮助
