Android Question Activity Attributes warning

I connect by Bluetooth to Tablet and use the Legacy Compile.
Notice these messages in the Logs.

Here are the settings in the Activity Ide editor.
#Region Activity Attributes
#FullScreen: False
#IncludeTitle: False
#End Region

Can not find any other Settings in Layout (Designer).
Where are the settings to be done?
