I know this is an old one...
Still, the issue is there!!!
B4XPages.GetManager.ActionBar.RunMethod("hide",Null)
but creates a bar with same height in the bottom, even with
In Main, and even in the "Activity" properties in the Visual Designer!
BTW, using AppCompat!
any solutions???
Found the solution!
when using AppCompat, in order to remove the Title bar you need to set it in the Manifest:
SetApplicationAttribute(android:theme, "@style/MyTheme")
CreateResource(values, themes.xml,
<resources>
<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>
</resources>)
