Question

@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
    switch (playbackState) {
        case Player.STATE_IDLE:  **//1.When this happens ?**

            if (playWhenReady==false) {  **//2.What "playWhenReady" indicate ?**

                **//3.When this condition occur ?**
            }
            else{
                **//4.When this condition occur ?**
            }
            break;
    }
}

“onPlayerStateChanged(boolean playWhenReady, int playbackState)”方法中的“playWhenReady”是什么？ & 玩家何时进入“Player.STATE_IDLE”？给定代码中提及的所有四个阶段何时发生？
