help me to resolve the issue

Hi,

I have attached to the Completed event of an Entry view however when I press the Done button on my Android device the event doesn't fire.

However the event does fire when running the same application on a Windows Phone.

Has anyone else experienced this?

Thanks

Problem Statement:

I am trying to display a hosted PDF from a secure site using https in a WebView using Xamarin.Forms.

What I Have Tried:

I have a custom renderer for the Android WebView control.

If I try using the pdfjs library, I get the following output

Below is my custom renderer:

public class BindableWebviewRenderer : WebViewRenderer
{
    public BindableWebviewRenderer(Context context)
        :base (context)
    {

    }

    protected override void OnElementChanged(ElementChangedEventArgs<WebView> e)
    {
        base.OnElementChanged(e);

        if (e.NewElement != null)
        {
            var customWebView = Element as BindableWebView;
            Control.Settings.AllowUniversalAccessFromFileURLs = true;
            Control.LoadUrl(string.Format("file:///android_asset/pdfjs/web/viewer.html?file={0}", string.Format("file:///android_asset/Content/{0}", WebUtility.UrlEncode(customWebView.URL))));
        }
    }
}

I have also tried using

Control.LoadUrl("https://drive.google.com/viewerng/viewer?embedded=true&url=" + customWebView.URL);

But this just displays an empty page (it is also worth noting that the URL created from this also does not work in a browser).

Questions I Have Already Consulted:

• Show a pdf into a webview from a link inside that Website Xamarin
  android
• Android WebView: Display Website with PDF
• xamarin/docs-archive

Or is UWP supported too?

xamarin forms standard

look like a bug to me and I wonder how to bypass that..

[1]
on some devices the app crash when editor control got focus right after showing the keyboard.
[2]
(on my device) crashes after the clicking the done/next button when on landscape mode.
the error log in bellow.

so for [2] I tried to bypass that by:
having the editor int a frame parent control as so:

                 <Frame x:Name="frameEditor" IsTabStop="True" >
                     <Editor Margin="10"
                        x:Name="txtMemoriam"
                        HorizontalOptions="FillAndExpand"
                        AutoSize="TextChanges"
                        Placeholder="Memoriam"
                        Parent="frameEditor"

                        Completed="TxtMemoriam_Completed"
                        Focused="TxtMemoriam_Focused"

                        ></Editor>
                    </Frame>

so now: on landscape mode the "done" button change to "next" control...
and apparently, its give focus to DatePicker control (open the datepicker)... (it's unexpected Behavior but it prevents it from crashing...)

for the first issue, I have tried to set focus.. but i dont yet know if its working - cause its not crashing on my device (got the report from google play)..

    private void TxtMemoriam_Completed(object sender, EventArgs e)
    {
        //txtMemoriam.Unfocus();
        //frameEditor.Focus();
        Xamarin.Forms.Device.BeginInvokeOnMainThread(() =>
        {
            Task.Delay(1).ContinueWith(x => { this.txtMemoriam.Focus(); });
            Task.Delay(10).ContinueWith(x => { this.txtMemoriam.Focus(); });
            Task.Delay(100).ContinueWith(x => { this.txtMemoriam.Focus(); });
            Task.Delay(1000).ContinueWith(x => { this.txtMemoriam.Focus(); });
        });
    }

    private void TxtMemoriam_Focused(object sender, Xamarin.Forms.FocusEventArgs e)
    {
        this.txtMemoriam.Focus();

        Xamarin.Forms.Device.BeginInvokeOnMainThread(() =>
        {
            Task.Delay(1).ContinueWith(x => { this.txtMemoriam.Focus(); });           
            Task.Delay(10).ContinueWith(x => { this.txtMemoriam.Focus(); });
            Task.Delay(100).ContinueWith(x => { this.txtMemoriam.Focus(); });
            Task.Delay(1000).ContinueWith(x => { this.txtMemoriam.Focus(); });
        });  
    }

I have a simple ListView and I want its separators to span the whole length but the code I found that should enable it doesn't get recognized by IntelliSense and I get an error. The code is the following snippet taken from the Microsoft docs site:

<ContentPage ...
         xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core">
<StackLayout Margin="20">
    <ListView ... ios:ListView.SeparatorStyle="FullWidth">
        ...
    </ListView>
</StackLayout>

Unfortunately though it's not working for me and I get a squiggly line saying that "The attachable property 'SeparatorStyle' was not found in the type 'ListView'. Is there something wrong in my code? It is as follows:

I am running the my tests on the local emulator and they are working as expected but when i tried to run the same on the Appcenter, I am getting Object not set to an instance of object error. when i tried to find the actual error i found the app is not even initialising on the device.

splash screen image appear when navigate one page to another page. i want remove or hide after splash screen loaded.

I am getting following error while deploying the app using application loader:

ERROR ITMS-90022: “Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly ‘120x120’ pixels, in .png format for iOS versions >= 10.0.”
ERROR ITMS-90023: “Missing required icon file. The bundle does not contain an app icon for iPad of exactly ‘152x152’ pixels, in .png format for iOS versions >= 10.0.”

Any ideas how to fix this, Here is info.plist file

Hi,
how can I set the ToolbarItem.Icon property (in xaml) from the viewmodel that reads a resource embedded in a pcl?
Thanks in advance.

I have a XAML form linked to an MVVM with the binding. At the first call the form is rarely populated, from the second onwards, it works sporadically. No errors are ever generated.
This is the code:

            public int NumeroAnomalie { get; set; } = 0;
            public int NumeroFoto { get; set; } = 0;
            public bool ErrorFile { get; set; } = false;

I'm trying to implement XamlStyles in my app, but the FontSize doesn't work. TextColor, Font, HorizontalTextAlignment, Margin all seem to be working, but i'm not sure what's going on with FontSize..

any ideas how to resolve this please?

In my Page:

<Label Text ="Edit Profile" Style="{StaticResource HeaderStyle}" />

In App.Xaml:

       <Style x:Key="HeaderStyle" TargetType="Label">

            <Setter Property="TextColor"    Value = "Red"/>
            <Setter Property="Font"         Value = "Hind-Bold"/>
            <Setter Property="HorizontalTextAlignment"    Value = "Center"/>
            <Setter Property="Margin"    Value = "0,60,0,0"/>

            <Setter Property="FontSize" Value="30"/>

        </Style>

I am trying to upload the .ipa file using Application Loader. The .ipa built using VS.net Xamarin. While deploying the .ipa file using Application Loader I am getting following error:

Any ideas how to fix this? I have removed the bin and obj folder from the forms and ios project, also clean the project and rebuild it multiple times, but still having the same issues.

Hi all,
I just want to add an multicolored icon on my tabbedPage but my tabbedPage display the icon with one color
thanks for ur help

My Code Like This.

public class OtpReceive : FormsAppCompatActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
NavigationPage nav = new NavigationPage(new MainPage() { Title = "First Page" });
}
}

Trying to figure out if at all possible to set what is effectively a hover color for toolbar icons.

I have toolbar icons with dark background and white icons, and hovered selections turnout dim and don't stand out as they should. Obviously more important for a mouse input than touch as in the UWP case, but also ideal if the same can be easily set for Android (if cross-platform option doesn't exist), say in styles.xml (which I am getting to know some of the settings in there, such as Toolbar height setting, etc).

• Can you set the toolbar icons hover color across all platforms, and if so how?
• Is there an equivalent Android setting in styles.xml?

I am trying to install Xam.Plugin.Connectivity in my Xamarin. Forms project which is targeting .NetStandard 2.0 Standard. But I am getting following error:

Error NU1202 Package Xam.Plugin.Connectivity 3.2.0 is not compatible with netstandard2.0 (.NETStandard,Version=v2.0). Package Xam.Plugin.Connectivity 3.2.0 does not support any target frameworks.

My Forms version is : 3.4.01008975

The weird thing is it was working fine until my Computer got rested (Without deleting any data except uninstalling recently installed applications) yesterday due to some issue. After that when I try to open my project I got so many errors related to different stuffs. But it was working fine before Reset.

I'm looking for a way to extract the Exif data (specifically, gps coordinates where photo was taken, when available) from images on the phone, both iOS and Android.

XLabs Media Picker doesn't provide this information, and neither does the Xamarin Media Picker plug-in. None of the meta data for an image is set with either of these solutions. Has anybody implemented a way to get this information from an image on the phone?

This is how I take the picture.

             Location location = new Location();
                    location.Latitude = 52.0271723411551;
                    location.Longitude = 0.764563267810425;

                photoFile = await CrossMedia.Current.TakePhotoAsync(new StoreCameraMediaOptions
                {

                    SaveToAlbum = true,
                    Location = location,
                    Directory = "Komunalac",
                    Name = "photoKomunalac.jpg",
                    SaveMetaData = true,
                });


                var picInfo = ExifLib.ExifReader.ReadJpeg(photoFile.GetStream());

                imageSource = ImageSource.FromStream(() =>
                {
                    return photoFile.GetStream();
                });

And the picInfo does indeed hold the metadata with GPS location.

But then when I want to get the picture back from album using :

 photoPicked = await CrossMedia.Current.PickPhotoAsync(new PickMediaOptions
                {
                    PhotoSize = PhotoSize.Medium,
                    SaveMetaData = true
                });

                picInfo = null;


                if (photoPicked != null)
                {

                    picInfo = ExifReader.ReadJpeg(photoPicked.GetStream());

                    imageSource = ImageSource.FromStream(() =>
                      {
                          return photoPicked.GetStream();
                      });
                }

picInfo here doesn't contain the GPS metadata. Anyone knows what went wrong or a different way to save the image with metadata to the android/ios?
