Can't import project, please help

[AndroidDeveloperLB]

It says :
Error:Android Source Generator: [android-layout-samples] AndroidManifest.xml file not found

But it doesn't make sense: I can see the manifest file...
Why does it happen?

I've tried to uninstall Android-Studio and put the Canary build, and now I get this instead (when trying to import from Git) :
"The project is using an unsupported version of the Android Gradle plug-in (0.9.2). The recommended version is 0.14.2."
