Asymmetric encryption using keystore with fingerprint authentication

Hello,
For my project I try to create a private and public key on keystore and keychain. But I would like protect the access of the keys with fingerprint authentification.

I find a lot example to create keys. Unfortunately I can't add link in this post ..
I didn't find any example for protect my keys with authentification. Do you have some information about that ?

Moreover, I hear that it's possible on native Android to unlock key when the user unlock the smartphone (scheme, pin or fingerprint). Do you know if it's possible with Xamarin ?

Thanks for your answer ;)

Hi there,

I have a picker as a children on my stacklayout. If i press it, the items at the picker are shown, and i can select one. So far so good.

However i want to show it without having to press it, that is, for instance if i have an option at the tabbar, and i press it, i want the picker to show.
How can i achieve this?

Thank you!

loading HTML with resources in application internal storage directory

My application tries to load a HTML string to webview. The HTML refers to an image file which is stored in the application internal storage directory "/data/data//files". The HTML is displayed, but a "broken link" image is displayed instead of the image. My code is like below

===============================================================================================

var myhtml = "<html> <body> <img src=\"Chrysanthemum.jpg\" alt=\"Chrysanthemum.jpg\" height=\"55\" width=\"55\" /> </body> </html>";

string baseURL = System.IO.Path.Combine("file://" + System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal) + "/");

webView.LoadDataWithBaseURL(baseURL, myhtml, "text/html", "UTF-8", null);_

===============================================================================================

If I store the file in the application "assets" folder and use "file:///android_assets/" as the baseURL, the image is displayed properly. Unfortunately my application downloads these images and cannot use them from assets folder.

Is anything wrong with this approach? Any help would be greatly appreciated.

PS. When I tried the same logic in Android native app (not Xamarin.android), the same baseURL loads the image properly.

Line Chart with OxyPlot.Xamarin.Forms show track on point tabbed

Hi, I'm working with a line chart with the OxyPlot.Xamarin.Forms plugin, this is the plot function:
public PlotModel GetLineChart()
{

        OnPropertyChanged("GraphModel");

        var model = new PlotModel
        {
            LegendPlacement = LegendPlacement.Outside,
            LegendPosition = LegendPosition.BottomCenter,
            LegendOrientation = LegendOrientation.Horizontal,
            LegendBorderThickness = 0
        };
        model.PlotType = PlotType.XY;
        model.InvalidatePlot(false);

        Dictionary<string, List<Prices>> values = HistoricData[Selected.ProductId];


        int colorIndex = 0;
        List<string> x_names = new List<string>();

        foreach (var item in values.Keys)
        {

            if (item.ToUpper() == Selected.ProductName) { SelectedIndex = colorIndex; }
            var lineSeries = new LineSeries()
            {
                Title = item,
                MarkerType = MarkerType.Circle,
                //TrackerFormatString = "X={2},\nY={4}",
                CanTrackerInterpolatePoints = false
                //LabelPlacement = LabelPlacement.Inside
                //LabelFormatString = "{0}"
            };
            lineSeries.MarkerResolution = 3;
            lineSeries.MarkerFill = OxyPlot.OxyColor.Parse(SubCategoriesViewModel.AvailableColors[colorIndex]);
            lineSeries.MarkerStroke = OxyPlot.OxyColor.Parse(SubCategoriesViewModel.AvailableColors[colorIndex]);
            lineSeries.MarkerSize = 3;

            var points = new List<DataPoint>();


            lineSeries.Color = OxyColor.Parse(SubCategoriesViewModel.AvailableColors[colorIndex]);

            foreach (var price in values[item])
            {
                points.Add(new DataPoint(price.Week+price.Year, price.Price));           
            }

            if (ButtonsVisibility.Count == 0)
            {
                lineSeries.IsVisible = (Selected.ProductName == item.ToUpper()) ? true : false;
            }
            else
            {
                lineSeries.IsVisible = ButtonsVisibility[colorIndex];
            }


            lineSeries.ItemsSource = points;
            lineSeries.MarkerType = OxyPlot.MarkerType.Circle;


            lineSeries.TrackerFormatString = "X={2},\nY={4}";
            lineSeries.TextColor = OxyPlot.OxyColor.Parse(SubCategoriesViewModel.AvailableColors[colorIndex]);

            model.Series.Add(lineSeries);
            colorIndex++;
        }

        NumButtons = colorIndex;

        LinearAxis yaxis = new LinearAxis();
        yaxis.Position = AxisPosition.Left;
        yaxis.MajorGridlineStyle = LineStyle.Dot;
        model.Axes.Add(yaxis);

        LineChart = model;
        OnPropertyChanged("GraphModel");
        return LineChart;

    }
}

Then in the LineChart.xaml.cs file:
protected async override void OnAppearing()
{
await _viewModel.LinearViewModel.GetSubCategoryHistoricWeekPrices(App.ViewModel.LoginViewModel.SesionToken, FROM_DATE, TO_DATE);

    Plot.Model = _viewModel.LinearViewModel.GetLineChart();
        PlotController controller = new PlotController();
        controller.UnbindAll();
        controller.BindTouchDown(PlotCommands.PointsOnlyTrackTouch);
        Plot.Controller = controller;

        AddButtons();
    }

My problem is that when the user taps one point of the line series, I want to display the track of that point, something like:
Track info of a point

But in my case, after a tap doesn't appear any track, I think that the problem is in the controller bindings on the OnAppearing method but I don't know which binding I should in the controller to show the track, any suggestion?

Hi.
I am using Xamarin.Forms on Visual Studio 2017. I am trying to use a dll that is compiled on 64bit. When i run the app on android emulator, it has a warning of "mismatch between the processor architecture" and the app crashed on the emulator. If i disable the initialization of the said dll, app runs fine.

Is it possible to use external dll's or api's on xamarin and if yes, how can we use those properly on xamarin.

Thanks...

Hello, I am unable to track this crash, it seems to happen on very specific devices but it's outside my code and I believe it's xamarin related.

[XAMARIN FORMS] problem of the link between my xaml view (with a picker) and the viewmodel

January 28, 2019, 8:48 am

Hello everyone,

I have a small problem, I explain myself:

here's what I did, I have a page with buttons (with different values) and a picker (see xaml code), when the user clicks on a button, normally the picker selection list proposes things that are linked to the value of my button through lists (see my view model code). Except it doesn't work!

In my opinion it is because of the static type that is on some of my lists and methods. So my picker which has a binding on one of my lists does not display my selection because it cannot access my list because it is in static and not a constructor (in which I call the element of my binding).

Do you have a solution for me?

If you can't understand me, don't hesitate to ask me questions?

you will find the different files with my code below.

Sincerely
Camille

Issue with committing project in Gitlab

I created a new xamarin forms project in Visual Studio(Not a new one, took a copy of my old project) and tried to commit the entire project to Gitlab. For that, I created a new project in Gitlab and enter the following commands.

cd project folder
git init
git remote add origin My project remote
git add .
git commit -m "Initial commit"
git push -u origin master

But when I push the new project, it gets committed to my old project. I have given the new project remote but it gets pushed to the old one(New project is a copy of old one).

Is there anyone faced this type of issue from Gitlab? Is there any file from gitlab to be saved to the old project? Why my new project commit redirect to the old one?

Are bugs going to be fixed ever in xamarin.ios storyboard designer?

January 30, 2019, 3:28 am

Hi there,
there are millions of bugs, errors, half-done stuffs in the storyboard designer of xamarin.ios in VS (windows).
Menus which empty with empty submenus, or with default texts (clearly the programmer add it but never used it).
Icons with no image, which opens empty menus.
Multiple times I have to select and de-select the same controller to see the properties.
In one project it can see the images and show them in drop-down (for example for buttons), in other project it asks me to add the image. When I add the image, it ask again to add the image, and again...and again...but the image never added.
Constantly complaining because the storyboard is not saved (even straight after I saved it, or didn't even opened to change it)
Constrains set, and automatically unset within seconds. To change or set more then two constrains I have to set one, save, close and re-open the designer and set one again...etc.
It just change properties over sometimes randomly when I open it, or just clear the name of a controller randomly.
I need sometimes 10-15 mins to change the name of a simple UIImage box because it doesn't want to save it. I have to do it 4-5x times when once it gets saved.
I like Xamarin but that designer is the most bug-full software what I ever seen in my career.
I can't even get how a company can release something what is clearly not even in beta version.
So my question is that, is it going to be fixed, or at least fully finished ever ?

Reproduce carousel view behaviour/animation/transition to a horizontal scroll view.

Hey developers,
I have so far tried to use a carousel view due to its ease of use and of course its performance. But I tried to show the tail of each UI elements (let's say we've a bunch of cards) whatever the position is as shown in the picture. I've googled a lot and posted another question in this forum but since then I changed the project UI a little bit so I ignored the given solution and now I am on my own again, I resolved it (show the next card's tail or/and the previous), I'll write down the structure I used in XAML but first let me highlight my requirements.
I want to reproduce the behaviour, animation/transition on swiping of the carousel view to my view, because I am actually using a horizontal scroll view with a Flex layout inside.
Here is the structure :

Now I've tried two options :
1- Use of Scrolled event in the scroll view but that hasn't been a great option because it fire the events (animation or transition) after the scroll is done, in my case it should fire the event since scrolling started.
2- Use of SwipeGestureRecognizer on Scrollview, FlexLayout and BoxView : couldn't get a stable behaviour on the 2 first attempts but when I used a BoxView I couldn't get each StackLayout (the StackLayout is my card) inside the BoxView (It wasn't built for that).

Here is my UI after I used a horizontal scroll view :

here is the behaviour I wanted to reproduce to my view :

I am unable to set the particular page in Carousel view

Hi, I am implemented the Carousel view using https://blog.xamarin.com/flip-through-items-with-xamarin-forms-carouselview/. And I am able to implement the Carousel,
**But My Problem I want to set the startup page while opening (I mean when page is loaded the carousel view should show 5th page or 4th index) **

Plugin Used
Xamarin.Forms.CarouselView (2.3.0-pre2)

What I tried
Case 1: I have used Data binding in xaml but it always showing first page or index of zero

Case 2: I have used Data binding from .cs file like CarouselView.ItemSource= Images; and CarouselView.Position=5; but is giving unhandled exception i.e, System.DivideByZeroException: Attempted to divide by zero.

Here is the Sample code

Case 1:

            <cv:CarouselView Position="{Binding Position, Mode=TwoWay}" ItemSelected="CarouselAlbumItems_ItemSelected" ItemsSource="{Binding AlbumItems}" x:Name="CarouselAlbumItems">
                <cv:CarouselView.ItemTemplate>
                    <DataTemplate>
                        <Grid  VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="*"/>
                                <RowDefinition Height="Auto"/>
                            </Grid.RowDefinitions>
                            <Image x:Name="imgAlbumItemName" Grid.RowSpan="2" Aspect="AspectFit" IsVisible="{Binding IsImage}" >
                                <Image.Source>
                                    <UriImageSource Uri="{Binding AlbumItemPath}" CacheValidity="14" />
                                </Image.Source>
                            </Image>
                        </Grid>
                    </DataTemplate>
                </cv:CarouselView.ItemTemplate>
            </cv:CarouselView>

Case 2:

    protected  override void OnAppearing()
    {
        base.OnAppearing();
        CarouselAlbumItems.ItemsSource = selectedItem.AlbumItems;
        CarouselAlbumItems.Position = position;            
    }
