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。
