中文：

1. 安卓平台当SDK小于27且系统版本为8.0.0时，并同时设置了android:screenOrientation="portrait"和true时，App将不能正常打开，我认为应该告知开发者，避免其他开发者遇到这个问题。
2. 请更新英文文档。

1. When the SDK is less than 27 and the system version is 8.0.0 on the Android platform, and the android: screenOrientation = "portrait" and true </ item> are set at the same time, the App will not work properly Open, I think developers should be informed to avoid other developers encounter this problem.
2. Please update the English documentation.
