A question: are you guys using any resources from appcompat? If not you can just copy the jar file to `libs` folder. If you are using please follow this guide:

https://developer.android.com/tools/support-library/setup.html

The way it is now is forcing all developers to have the same folder structure for the SDK and the project. The guide shows how to add a project to your current one and copy appcompat's source folder.
