Storing Android system icons in my own app

I've read that the references to the android system icons aren't fixed / could be changed and therefore it would be better to save them as a resource of your application. I once found a guide showing how to get the icons from the android repository but I can't find it again.

So my question is: How do I get the android system icons fro开发者_如何学Pythonm the repository? Which path are they in? I am confused by all the git files and stuff on https://android.googlesource.com

Android built-in system resources are stored with your Android SDK under

<SDK_path>/platforms/android-<API_version>/data/res

Since you want an icon, you should look into various drawable subfolders there and take the images you'd like to use.
