What is this overlay folder? How does it work? What is it used for? Where can I read more about it?

推荐答案

例如，假设您要为设备修改Android源代码中的某些文件(例如，您想要向Launcher资源添加其他字符串).不建议修改Android的实际来源.

For instance, imagine that you want to modify some files in Android source for your device (for instance, you want to add additional string to Launcher resources). It is not recommended to modify the actual sources of Android.

您将创建覆盖来模拟Android的实际文件系统路径布局，并在其中放置更改的文件.如果在Laucher中为字符串，则创建与以下路径相对应的目录:packages/apps/Launcher2/res/values并在其中放置修改后的strings.xml

Instead of this you create overlay that mimics the actual filesystem path layout of Android and put there your changed file. In case of string in Laucher, you create directories that corresponds to the path: packages/apps/Launcher2/res/values and put there modified strings.xml

因此，当您构建设备时，此文件将被替换.

Thus, when you build your device this file will be substituted.
