What is this big black bar at the bottom?

I am building an app in .NET MAUI. I started building it for a previous android version (API 22). The layout is fine for that version. But when I installed it on a later version of android (API 33), the vertical stack layout wasn't aligning as I wanted it to be.
I thought the problem was with how I arranged all these elements. So, I rewrote the XAML, but still didn't achieve what I was looking for. The black bar still remains at the bottom.

Is anyone aware of any bugs specific to Android for this control?

Image overflow in ListView Xamarin.Forms (Android)

have a ListView in which for each element of the List you have 3 buttons for 3 different options, when you enter the screen there are no overflow problems in the images of the ImageButton, but when you do the first scroll the sources start to overflow as shown in the following image
The images lose the center and are misaligned as you scroll up or down, this problem does not occur in iOS, only occurs in Android (version 6,7,8 and 9), apparently it is a problem like Android render the images
I tried, changing the ImageButton control to Button and the problem persists, also trying to assign the "Aspect" property to the ImageButton, but I'm not getting successful results, any help how to fix this? then my code XAML
<ListView

How can I avoid this behavior? Any help for me?

I suggest you use (Frame + image ) instead of ImageButton , and add tapgesture on it .

How to make a FloatingActionButton work on top of a ListView and position it correctly

I am trying to get a SuaveControls.FloatingActionButton to work on top of a ListView following the example on this page - https://devlinduldulao.pro/how-to-create-a-floating-action-button/
My ListView is inside a StackLayout so I decided to wrap them into an AbsoluteLayout
Here is the View/XAML
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

x:Class="DPM.XForms.ProjectListPage"

>
<AbsoluteLayout>
<StackLayout Orientation="Vertical" Spacing="1">
<Label Text="TopBar ..." BackgroundColor="Gray" HorizontalOptions="FillAndExpand" HorizontalTextAlignment="Center"/>
<!-- Project Search/Filter toolbar-->
<StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand" Padding="7" BackgroundColor="White">
<Label Text="Projects " TextColor="DarkGray" Font="Bold,17" HorizontalOptions="Center" VerticalOptions="Center"/>
<StackLayout Orientation="Horizontal" HorizontalOptions="EndAndExpand" Padding="0">
<Button Image="Search.png" BackgroundColor="White" WidthRequest="27" HeightRequest="27"></Button>
<Button Image="LeftBS.png" BackgroundColor="White" WidthRequest="27" HeightRequest="27"></Button>
<Button Image="CenteredBS.png" BackgroundColor="White" WidthRequest="27" HeightRequest="27"></Button>
<Button Text="++" WidthRequest="27" HeightRequest="27" Clicked="CreateProject_Clicked"></Button>
</StackLayout>
</StackLayout>
<Label Text="Pin projects" HorizontalOptions="FillAndExpand" HorizontalTextAlignment="Center" BackgroundColor="LightGray" HeightRequest="25" />
<ListView x:Name="lvProjects" ItemTapped="OnProjectTapped" RowHeight="54" BackgroundColor="DarkGray">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<!-- Project Row -->
<StackLayout Orientation="Horizontal" HorizontalOptions="Fill" BackgroundColor="White" Margin="0,1,0,1" >
<Button

</Button>
<StackLayout Orientation="Vertical" HorizontalOptions="StartAndExpand">

VerticalOptions="Start"
/>
<Label

TextColor="Black"
HorizontalOptions="Start"
VerticalOptions="Start"
/>
<Label
Text=".."
TextColor="Black"
HorizontalOptions="Start"
VerticalOptions="End"
/>
</StackLayout>
<Button Text="3" WidthRequest="44"></Button>
<Button Text=">" WidthRequest="44" BackgroundColor="White" ></Button>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
<views:FloatingActionButton
Image="CreateProject.png"
WidthRequest="80"
HeightRequest="80"
HorizontalOptions="CenterAndExpand"
VerticalOptions="CenterAndExpand"
Clicked="FloatingActionButton_Clicked"
>
</views:FloatingActionButton>
</AbsoluteLayout>
</ContentPage>
But with this approach two things are happening
When the device is in Landscape mode the ListView is not growing as it did before adding the AbsoluteLayout
Dont know how to position the FloatingActionButton to always stay on the lower right corner of any device
I have also tried placing the FloatingActionButton inside the current StackLayout but it does not float is just added below or above the listview as a regular "row" like is shown here
Feel free to use the comments if something is not clear.

You can remove absolute layout since you can see that your layout doesn't fully expand at landscape mode.
You can try this one
<MainLayout VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
//YourTopBar
// YourListView
<StackLayout HorizontalOptions="End"
VerticalOptions="End"
Spacing="0"
Margin="15">
<YourFloatingButton />
</StackLayout>
</MainLayout>
The mainlayout can be a grid or stacklayout

You can modify the layout to use Grid and AbsoluteLayout to wrapper the listview and Floating button. So it is somethig like the following:(As I don't have your list datasource, to be simple, I just put a mock list)

And the result is like this:

Based on #Swift_Talt answer and this discussion- https://forums.xamarin.com/discussion/52420/create-a-layered-page-layering-controls
I found this solution using a Grid of one (1) cell where the ListView (background) and the FloatingActionButton are on the same unique cell
This is how it looks:
