Launcher3修改 wm density界面布局不改变
/packages/apps/Launcher3/src/com/android/launcher3/InvariantDeviceProfile.java
Launcher的默认配置加载类，通过InvariantDeviceProfile方法可以看出，
CellLayout显示的应用行数和列数可以通过findClosestDeviceProfiles查询XML配置来读取配参

Android 12之后,Launcher3有两个模式,一个是平板,另一个是手机.
手机模式:桌面默认是不可以旋转的.
桌面设置页面:桌面空白处长按,进入home settings,有个allow home screen rotation就是旋转开关,手机模式默认是关闭的,平板模式这个偏好隐藏了.

关于3.0Ver 利用role不需要删除旧Launcher栈的补充.
case 1: 单独使用role,确实不需要删除旧Launcher栈,唯一需要注意点的是要在Launcher启动之前,把android.app.role.HOME替换,
所以需要在framework里某个必经之路上做文章...
