高通Android 12/13 Launcher3修改RecentView与屏幕方向保持一致

1、背景：

最近同事遇到一个需求说，recentview应用预览与屏幕方向不一致问题，于是加了一些系统日志，实现此需求。简单记录下哈。

源码修改路径汇总如下

 packages/apps/Launcher3/quickstep/src/com/android/quickstep/util/RecentsOrientedState.java
	修改:         packages/apps/Launcher3/quickstep/src/com/android/quickstep/views/TaskThumbnailView.java
	修改:         packages/apps/Launcher3/src/com/android/launcher3/settings/SettingsActivity.java
	修改:         packages/apps/Launcher3/src/com/android/launcher3/states/RotationHelper.java

2、源码修改diff如下所示

3、最后展示RecentView与屏幕方向保持一致。转载请注明出处高通Android 12/13 Launcher3修改RecentView与屏幕方向保持一致-CSDN博客，谢谢！

注意事项：

1、修改完之后记得make clean全编，不然可能没生效哈！

2、app应用强制设置竖屏这里暂时不考虑哈！需要可以自行修改app方向（通过配置横竖屏二套布局文件或者在清单文件中默认配置。）
