I cannot install the application on device no longer.

I have tried:

• change the package name, application name & version number.
• adb uninstall com.myapp.name.
• reboot my physical device
• try to delete manually in Android application manager
• I've tried to search the device files but couldn't find any related information - i have looked for "ExternalStorageDirectory", "com.myapp.namexxx", "com.myapp.name"

this is the Error:
Error: Device could not find component named: com.myapp.name/md5aa90eac5c6d14c19e9c8e7ab0853061c.SplashActivity
The application could not be started. Ensure that the application has been installed to the target device and has a launchable activity (MainLauncher = true).
Additionally, check Build->Configuration Manager to ensure this project is set to Deploy for this configuration.
Couldn't connect debugger. You can see more details in Xamarin Diagnostic output and the full exception on logs.

this is the Diagnostic output end (too long for the post):

I have a collection view with rss items with property

public string Id { get; set; }
public bool IsReaded { get; set; }

I need to set IsReaded property to true as scrolled through the items

I thought of using LastVisibleItemIndex so for every 5 items set there IsReaded property to true but how to get these items ids?

or if there are another suggested approaches

If you have enabled the navigation page, with the back button (the "<" icon) and the title, when the screen reader focus is on the back button it read "unlabeled button". Is there a way to change is Accessibility name to a proper "back button" or whatever else? Either in Android and iOS

Hi, I have a field called Size and it's a decimal field so I expect user to enter decimal values but when I tried to debug and enter the decimal value, emulator does not accept decimals. I can enter the whole number but not the decimal. Any suggestions? TIA.

Hello! What is the best way to display font icons with data being pulled from a web service? I want to store the value of the icon and display the icon similar to the rest of the information, but with a custom font icon.

I have a xamarin forms app working with data from a webservice successfully. Here is my model.

public class TypeModel
{
    [PrimaryKey]
    public int pType { get; set; }

    public int fDepartment { get; set; }

    public string Title { get; set; }

    public string Description { get; set; }

    public string Icon { get; set; }

    public string Version { get; set; }

}

I also got the font icons working successfully like the tutorial at [1]: https://montemagno.com/using-font-icons-in-xamarin-forms-goodbye-images-hello-fonts/ I got my icons stored under this class. Trying to transition to managing these values with web service or array if I have too now.

public const string IconCheckMark = "\uf12c";

public const string IconSearchGlass = "\uf349";

public const string IconQuestionMark = "\uf2d6";

public const string IconQuestionCircle = "\uf2d7";

But here is where my problem starts. My ViewModel is doing the work to create the collection. How do I assign a value that will display and match correctly.

public ObservableCollection<TypeModel> TypesCollection { get; set; }

TypesCollection.Clear();

IEnumerable<TypeModel> types = await DataSource.GetTypes();

foreach (var key in types)
{
    \\Original value doesn't display correctly, shows like \U f 1 2 c when debugging on emulator
    \\key.Icon = key.Icon;

    \\Works and displays correctly but static data displays one icons for all
    \\key.Icon = "\uf12c";

    \\Works and displays correctly but static data displays one icons for all
    \\key.Icon = FontClass.IconCheckMark;

    TypesCollection.Add(key);    
}

Nice and simple after that for the xaml files.

Hey guys, I want to know why in the new project with the master detail template there is a delay for android in the MainPage.xaml.cs and some especific code for iOS in the MainPage.xaml. I'm using the most updated version of visual studio 2019.

Here is the portion of MainPage.xaml:

<MasterDetailPage.Detail>
    <NavigationPage>
        <NavigationPage.Icon>
            <OnPlatform x:TypeArguments="FileImageSource">

        <x:Arguments>
            <views:ItemsPage />
        </x:Arguments>
    </NavigationPage>
</MasterDetailPage.Detail>

Here is the portion of MainPage.xaml.cs:

public async Task NavigateFromMenu(int id)
{
    if (!MenuPages.ContainsKey(id))
    {
        switch (id)
        {
            case (int)MenuItemType.Browse:
                MenuPages.Add(id, new NavigationPage(new ItemsPage()));

                break;
        }
    }

    var newPage = MenuPages[id];

    if (newPage != null && Detail != newPage)
    {
        Detail = newPage;

Hi all,
I'm having a problem on xamarin ios and android. if the device has set the text and display size to large, all the sizes in my app become enlarged.
how can I set the default when opening the app?
I have no idea where to put or disable the system configuration of the text or display size. I have tried using this help:

    using Xamarin.Forms;
    using Xamarin.Forms.Platform.Android;

    [assembly: ExportRenderer(typeof(Label), typeof(MyApp.Droid.Renderers.LabelRendererDroid))]
    namespace MyApp.Droid.Renderers
    {
        class LabelRendererDroid : LabelRenderer
        {
            protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
            {
                base.OnElementChanged(e);
                if (e.NewElement == null) return;
                Control.SetTextSize(Android.Util.ComplexUnitType.Dip, (float)e.NewElement.FontSize);
            }
        }
    }

but besides being obsolete, it is only for android.

I've been developing my app now for at least 5 months. I've been wanting to try the xamarin previewer so i updates visual studio xamarin forms and then i updated my nuget xamarin forms for my portable, ios and android.

now when i try to debug the application on the device i get

System.TypeLoadException: Could not resolve type with token 01000012

on this line

global::Xamarin.Forms.Forms.Init(this, bundle);

which i find very odd

origionally my xamarin forms nuget version was 2.3.3.168

so i thought id update to the stable version which was the same version number 2.3.3.168 but it had "stable" beside it

i've downgraded again but still get the same error.

any thoughts

thanks

Hi,

I have a xamarin forms project with Xamarin.Forms v4.5 with Vs 2019.

And I compile with using Android 10.0 Q.

When I build in debug mode it's extremely long.

In my output it hangs 10 minutes on the line:

1>------ Build started: Project: Dev.Mobile.Android, Configuration: Debug Any CPU ------

Once it passes this step it's quite fast.

My setup for the build is:

What could bhe the issue? How can I investigate?

Thanks,

https://docs.microsoft.com/en-us/xamarin/xamarin-forms/xaml/resource-dictionaries#stand-alone-resource-dictionaries

According to this documentation, it's possible to split the app styling into individual resources Dictionary, by modifying a content page /view .

I have done this, and moved a section of styling to this Dictionary, my problem is then access these resources from other content.

Normally I would define it in the App level resource Dictionary, and then consume by

Style="{StaticResource HeaderBackGround}"

This of course can't be resolved.

So how do you consume a Stand-alone Resource Dictionary?

I want to add a TabbedPage as a child of another TabbedPage, it works fine for me, but when I press the back button the application throws me an exception: Java.Lang.IllegalStateException: 'FragmentManager is already executing transactions'

We have a really simple app, the idea is the timer will update a label on the home screen depending on different configuration within the mobile app. I have created the binding and can update the homepage from it's self but not from the timer. I think what is missing is a OnChange within the home page to detect if the string has changed.

Display layout code, bind the label to the name "LabelText"

<Label                
Text = "{Binding LabelText, Mode=TwoWay}"
x:Name="MainPageStatusText"
HorizontalOptions="CenterAndExpand"
Grid.Row="2"
Grid.Column="0" 
Grid.ColumnSpan="6"
VerticalOptions="CenterAndExpand"
TextColor="White"
FontSize="Medium"/>

=====
This is the class file to link the text string to the label, I can see it been called from the different places but when it's called from the app.cs it does not work

using System;
using System.Collections.Generic;
using System.ComponentModel;
using Xamarin.Forms;

namespace Binding_Demo
{
    public class MyClass : INotifyPropertyChanged
    {
        protected void OnPropertyChanged(PropertyChangedEventArgs e)
       { PropertyChanged?.Invoke(this, e); }

       protected void OnPropertyChanged(string propertyName)
       { OnPropertyChanged(new PropertyChangedEventArgs(propertyName)); }

       public event PropertyChangedEventHandler PropertyChanged;

      private string labelText;

      public string LabelText
      {
         get {
            return labelText;
            }


        set
        {
            labelText = value;
            OnPropertyChanged("LabelText");

         }
      }
   } 
}

=====
This is the code inside the homepage, this works and I can see it sending data to the text label

    public static MyClass _myClass = new MyClass();
    public Homepage()
    {

        BindingContext = _myClass;
        _myClass.LabelText = "Inside the home page";

    }

======

This is the App.cs code, we start the timer and then want to set the text on the Homepage label. I can see the class been called, but it does not set the text.

 using System;
 using System.Diagnostics;
 using System.Threading.Tasks;
 using Xamarin.Forms;
 using Xamarin.Forms.Xaml;

 namespace Binding_Demo
 {
 public partial class App : Application
{
    public static MyClass _myClass = new MyClass();

    public App()
    {
        //InitializeComponent();

        Device.StartTimer(TimeSpan.FromSeconds(10), () =>
        {

            Task.Run(() =>
            {
                Debug.WriteLine("Timer has been triggered");

                // !!!!! This is not setting the text in the label !!!!!
                BindingContext = _myClass;
                _myClass.LabelText = "Inside the timer app";

            });
            return true; //use this to run continuously
        });

        MainPage = new NavigationPage(new MainPage());
    }

    protected override void OnStart()
    {
        //

    }

    protected override void OnSleep()
    {
    }

    protected override void OnResume()
    {
        // force app to mainpage and clear the token  


    }
}

}

I couldnt find Icon Property inside my toolbar and IconImageSource is not helping,
I have created icons from android assest and had all icon inside mipmap according to resoulation,
{

<?xml version="1.0" encoding="utf-8" ?>

<TabbedPage.ToolbarItems>

</TabbedPage.ToolbarItems>

<Local:PaProfile Title="Profile"
                 IconImageSource="Profile.png"/>

}
Same Problem for Profile PAge Also.

The class, property, or method you are attempting to use ('.ctor') is part of IndicatorView; to use it, you must opt-in by calling Forms.SetFlags("IndicatorView_Experimental") before calling Forms.Init().

but in the ManActivity.cs I have set the flag:
`base.OnCreate(savedInstanceState);

        global::Xamarin.Forms.Forms.SetFlags("CollectionView_Experimental");
        global::Xamarin.Forms.Forms.SetFlags("IndicatorView_Experimental");
        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        global::Xamarin.Forms.Forms.Init(this, savedInstanceState);`

it still give an error?

Hi,

I want to integrate an image editor (similar to adobe creative SDK or Img.ly SDK) into xamarin.forms app, can anyone please suggest me a cross platform image editor?

This is my NavBar title view:

<NavigationPage.TitleView>
        <StackLayout Margin="0" Padding="6,0,6,0" BackgroundColor="Yellow"
                     Orientation="Horizontal">
            <Button VerticalOptions="Center" ImageSource="backArrow_icon.png"
                    HorizontalOptions="Start"
                    HeightRequest="30" MinimumHeightRequest="30"
                    WidthRequest="30" MinimumWidthRequest="30"/>
            <Label VerticalOptions="Center"
                   HorizontalOptions="StartAndExpand"
                   Text="{x:Static resources:AppResources.Share}"/>
            <Button VerticalOptions="Center" ImageSource="Check_Icon.png"
                    HorizontalOptions="Start"
                    HeightRequest="30" MinimumHeightRequest="30"
                    WidthRequest="30" MinimumWidthRequest="30"/>
        </StackLayout>
    </NavigationPage.TitleView>

How do I make the menu icon marked in red, invisible? or get rid of it?
