无法在Android Oreo中设置屏幕方向

Question

现在我正在开发一个android应用程序，我想将屏幕方向设置为横向模式，在所有设备上都可以正常工作，但是问题是当我尝试在android oreo中运行该应用程序时，该应用程序崩溃了。拜托，有人帮我吗？

我在这里添加了日志，

我这样设置方向

 requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    overridePendingTransition(R.anim.do_not_move, R.anim.do_not_move);
    setContentView(R.layout.activity_main);
    //set screen orientation
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
