Unity 4.6.1p3 included this fix:
(609026) - Android: Fixed theme attribute in default manifest to hide title bar during startup.
So with the default AndroidManifest the titlebar should be hidden.
Thank you very much! I created an android manifest with the android:theme setting and copied it in plugins/android.
Last question: in the opening animation (in lollipop the window scrolls from bottom to top) it’s normal that for a moment the app closes itself and then it re-opens? In less words, for a moment i see the home menu.
Sorry again for english
