Unforgettably there is no OnStart Listener expose by Android. After Prepared State, the MediaPlayer goes into Started State once playback started.
令人难忘的是，Android 没有公开 OnStart 侦听器。在 Prepared State 之后，MediaPlayer 一旦开始播放就进入 Started State。
But in Prepared State only you should have sufficient buffer to play. Can you use setOnBufferingUpdateListener (MediaPlayer.OnBufferingUpdateListener listener) and print percentage of buffer. So that way you can see, if in Prepared State you have enough buffer or not.
但是只有在准备状态下，您才应该有足够的缓冲区来播放。您可以使用 setOnBufferingUpdateListener (MediaPlayer.OnBufferingUpdateListener listener) 并打印缓冲区的百分比。这样您就可以看到，如果处于准备状态，您是否有足够的缓冲区。
