我通过在 onSavedInstanceState 和 onStop 上发布 YouTubePlayer 来解决这个问题。

@Nullable
protected YouTubePlayer mUtPlayer;

@Override
public void onSaveInstanceState(Bundle outState) {
    /* release ut when home button pressed. */
    if (mUtPlayer != null) {
        mUtPlayer.release();
    }
    mUtPlayer = null;
    super.onSaveInstanceState(outState);
}

@Override
public void onStop() {
    /* release ut when go to other fragment or back pressed */
    if (mUtPlayer != null) {
        mUtPlayer.release();
    }
    mUtPlayer = null;
    super.onStop();
}
