Robolectric 2.3 & android annotation - robolectric

Question

After mulitple problems in order to use robolectric with android studio, i get an error to create an activity.
So i use the following code
#Before
public void setUp() throws Exception {
mapActivity = Robolectric.buildActivity(MapActivity_.class).create().visible().get();
}
I've decided to build annotated activity but i fall on this problem (same problem if i build "normal" activity)

To remove this warning, annotate your test class with #Config(manifest=Config.NONE).
