I try to use on official ICS firmware but it doesn't work...
Flash is ok but i have black wallpaper (cant change) and no status bar
(with the buble pakck)
+!
That grey is in framework-res.apk not in systemUI. It is active notifications so it is managed by the framework.
<item type="drawable" name="notification_item_background_legacy_color">#ff111111</item>
If TargetSdkVersion is lower than Build.VERSION_CODES.GINGERBREAD(APILevel9), set R.drawable.notification_row_legacy_bg!!
