问题分析：

在Android11版本的机器上打印堆栈,关闭屏幕旋转后横屏手机会进行如下调用

在Android GO机器上添加相同的log,关闭屏幕旋转在手机横屏时无任何log打印

由此可见OrientationListener并未往下调用

而控制OrientationListener  disable或enable的参数在DisplayRotation.java中

//frameworks/base/services/core/java/com/android/server/wm/DisplayRotation.java
    
    int showRotationSuggestions = ActivityManager.isLowRamDeviceStatic()
    
                        ? Settings.Secure.SHOW_ROTATION_SUGGESTIONS_DISABLED
    
                        : Settings.Secure.getIntForUser(resolver,
    
                        Settings.Secure.SHOW_ROTATION_SUGGESTIONS,
    
                        Settings.Secure.SHOW_ROTATION_SUGGESTIONS_DEFAULT,
    
                        UserHandle.USER_CURRENT);

在该位置会判断设备是否为低内存设备，如果是低内存设备则

showRotationSuggestions = Settings.Secure.SHOW\_ROTATION\_SUGGESTIONS\_DISABLED

因此，在Android Go当中不会显示屏幕旋转按钮

该现象可以进行修改，并且修改后功能正常

**但是，单独打开某几个go版本限制功能，是不会有太大问题的，只是随着打开的限制越多，逐渐积累可能会出现内存不足问题。**
