引发问题原因

1.在使用SurfaceView+MediaPlayer进行视频播放时使用

SurfaceHolder holder = mSurfaceView.getHolder();
holder.addCallback(new MyCallBack());

正常使用时会直接调用CallBack()的surfaceCreated回调方法，在回调中调用播放等方法进行视频播放，可是经过使用发现在SDK大于23时，首次不会执行回调，所以在addCallback后手动调用了播放视频的操作，但是此时SurfaceView还没有准备好，就会报次错误，所以在调用播放时应按照如下方式处理，判断是否有效：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && holder.getSurface().isValid()) {
    mediaPlayerPlayVideo(holder);// 播放视频操作
}
