Tab indicator in Xamarin Forms Tabbed Page placed at bottom
I have a Xamarin Forms bottom placed tabbed page rendered using C#. I want a tab indicator to be displayed above each tab icons as it would in a top placed tabbed page. Is it possible? I am not able to find solution anywhere. I came across this SO post - https://stackoverflow.com/a/41570159/10329199, where we can define app:tabIndicatorColor="#123456" in Tabbar.axml. But I didnt work because I'm rendering the tabbar using C# not in AXML. I also want this tab indicator in iOS. Thanks

Xamarin Live Player vs Gorilla Player
Can someone tell me what is better at the current moment? Xamarin Live Player is official, but still in development. Gorilla player seems more stable. Did you test them both so you can tell me the differences?

This app is incompatible with all of your devices
Hi,
I have published my first app and it is working well on my mobile. But I can't find it from play store search as well as other people. When I open it directly from the link I can see the message: This app is incompatible with all of your devices. Probably this is why I can't find it.
Can you help me fix it?

Custom Map tiles Overlay hides my routes highlight
Hello everyone, I'am currently working on a Pcl project that, among other things, displays a custom map.
I have used this tutorial to customize my map :
and this one to add custom map tiles.
and finally I used this tutorial to highlight routes on the map :
My map works well, the custom tiles overlay looks nice and I managed to change the look of the pins on the map (yay!)
Now my problem is this : My highlighted routes are not visible on the map.
I know the routes are being displayed because if I zoom in or zoom out of the map, I can actually see the highlighted routes during the short time the custom tile overlay is loading and is not being displayed.
wich makes me guess that my map tiles overlay hides my highlighted routes.
I wanted to know if this was a known issue because I couldnt find anything about this problem online. I can post my code if requested.
Thanks in advance for any bit of advice or ideas

Hi, I am facing Deployment to emulator error in Xamarin Forms
I am trying to build a Xamarin forms Application, It's a blank code, the code builds perfectly without error but it does not get deployed on an emulator.
If I click "Start without Debugging" then the application gets installed on my emulator or else it stays black and after building complete I get just a "Ready" output. It happened all of sudden. Visual Studio version: VS2017 15.9.6
Can anyone help me with this? It started out of nowhere.
I tried to search for mono in "Extensions and Update" to enable it but couldn't find anything installed. If I try to install mono it gives an error "Either it is not compatible or already installed"
Also in my registry, I can't find the SDK path.
I need visual studio to build and display output in emulator.!

CarrouselView, what happened?
I read some posts about Xamarin.Forms.CarouselView, but this still in pre-release state "2.3.0-pre2".
In some forum thread I read that the project moved to https://github.com/alexrainman/CarouselView with the possibility of merging into Xamarin.Forms.
Has been merged already at this version (Xamarin.Forms 3.5)?? . If not, Is there any plans soon?

UWP LaunchUriAsync failing without error message
I have a UWP app, and I am trying to get it to ask the device to open a pdf in whatever manner it chooses.
The code looks like this:
async static partial void OpenFileWithNativeApp(string filepath)
{
Device.BeginInvokeOnMainThread(async () =>
{
Uri targetUri = new Uri(filepath);
bool outcome = await Windows.System.Launcher.LaunchUriAsync(targetUri);
});
}
filepath is roughly: {file:///C:/Users/walter.fakename/AppData/Local/Packages/Guid/LocalState/PDFWhatever.pdf} . I can navigate to that place on my c drive, and the pdf is actually there.
When I run this code the outcome that is set by LaunchUriAsync is set to false, indicating that the Uri was not successfully launched. This is correct, as indeed, no other app launches the Uri. But it doesn't tell me how to fix it, such that the Uri would be successfully launched by whatever browser or pdf viewer the device associates with pdfs.
Does anyone see what I'm doing wrong?
-Regards,
Walter

Shell - Add page with constructor argument
I'm trying to use the new Shell for Forms 4.0
I have some pages that I would have added in the past like this new GenericPage("link");
Is there a way I can do that with Shell in xaml?
This is what I have now:
<ShellItem x:Name="RepSpotlight">
<ShellSection Title="Stats" Icon="tab_feed.png">
<ShellContent ContentTemplate="{DataTemplate local:Spotlight.StatsPage}" />
</ShellSection>
<ShellSection Title="Upcoming" Icon="tab_about.png">
<ShellContent ContentTemplate="{DataTemplate local:Spotlight.UpcomingPage}" />
</ShellSection>
<ShellSection Title="By Month" Icon="tab_about.png">
<ShellContent ContentTemplate="{DataTemplate local:Spotlight.ByMonthPage}" />
</ShellSection>
</ShellItem>
I'd love to be able to do something like this:
<ShellSection Title="Stats" Icon="tab_feed.png">
<ShellContent ContentTemplate="{DataTemplate local:Spotlight.GenericPage("stats")}" />
</ShellSection>
Or maybe something like:
<ShellSection Title="Stats" Icon="tab_feed.png">
<ShellContent ContentTemplate="{DataTemplate local:Spotlight.GenericPage}" parameter="stats" />
</ShellSection>
Is anything similar to this possible? How would I go about doing it?
Thanks!
