问题
According to the android developer page for the developer preview of L, it's possible to use the Outline class & define outlines for view's to display the shadows in the correct way. (http://developer.android.com/preview/material/views-shadows.html#shadows)
In my case, the "L"-sdk I use, didn't found it. Therefore I couldn't import and use the class.
According to the test project, stored in sdk/samples/android-L/ui/views/Elevation/ElevationDrag this class should be stored in "android.graphics.outline", but even in this project it can't be located correctly.
Is this feature not implemented in the developer preview yet or did I missed something?

Finally got it.
It's a bug in android studio. I just added manually the import to my activity:
import android.graphics.Outline
It will be shown as error, but it can compile & run. I hope they will fix this soon.
EDIT: I created an issue here: https://code.google.com/p/android/issues/detail?id=72788&q=android%20studio%20android%20l&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars
It looks like, they're working on it.
