Hello everyone,
I have a test.xaml file and his corresponding test.xaml.cs file in my common xamarin project.
When I add a "Clicked='MyHandler'" option on a tag in my test.xaml file, VS doesn't generate the code for the event in test.xaml.cs file...
I'm really stuck with this issue...
Hi developers,
I have a sample Xamarin Forms application and i'm using Zxing.Net.Mobile.
I can read QR Codes, ITF Small codes but, I can't read barcodes that has 44 digits.
My ideia is with app, read bank slip some figure below:
How do this?
It is my simples code:
`
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
}
async private void openScanner_Clicked(object sender, EventArgs e)
{
var opts = new ZXing.Mobile.MobileBarcodeScanningOptions
{
PossibleFormats = new List<ZXing.BarcodeFormat> { ZXing.BarcodeFormat.QR_CODE, ZXing.BarcodeFormat.ITF,
ZXing.BarcodeFormat.All_1D, ZXing.BarcodeFormat.EAN_13, ZXing.BarcodeFormat.CODE_39, ZXing.BarcodeFormat.CODE_128,
ZXing.BarcodeFormat.PDF_417, ZXing.BarcodeFormat.UPC_EAN_EXTENSION
}
};
opts.TryHarder = true;
var barcodeReader = opts.BuildBarcodeReader();
barcodeReader.Options.AllowedLengths = new[] { 44 };
ZXingScannerPage scanPage = new ZXingScannerPage(opts);
ITFReader
scanPage.OnScanResult += (result) => {
Device.BeginInvokeOnMainThread(() => {
Navigation.PopAsync();
DisplayAlert("Scanned Barcode", result.Text, "OK");
});
};
await Navigation.PushAsync(scanPage);
}
}
`
My root page is a ContentPage. I set it like this in App.xaml.cs:
public App ()
{
InitializeComponent();
MainPage = new MainPage();
}
when i detect a user is just authenticated for the first time I forward them to a registration screen that I want to be modal using the following code:
var editNamePage = new RegisterNameEditorPage();
await Navigation.PushModalAsync(editNamePage);
The navigation is successful and the screen works as designed when running in the Android emulator and a physical Android device. However when I run in an iOS simulator the fields do not take any user input. It's like they are hit test invisible. Basically my app is bricked. Can't do anything. This ONLY happens in iOS simulator (havent tried it on a physical iOS device). But it works correctly on Android simulator and physical device.
I'm trying to setup the airwatch SDK from this link: components.xamarin.com/gettingstarted/awsdk for use with Xamarin forms. The link has instructions for setting it up for android and IOs. Is it compatible with Xamarin.Forms? Does anyone have any examples with it working with forms?
Thanks,
I have a client that wants to use our mobile application but they seem unable to install it to their devices via Airwatch. Would my application need the Airwatch SDK or is it a setting on their end? Thanks in advance
We are using Xamarin Forms for Android and iOS. Is there documentation / steps to achieve the VMWare Airwatch SDK integration for Xamarin Forms on Android and iOS.
Thanks.
I need to have a custom view in Xamarin.Forms. I need the header to have button in the middle of it, not a toolbar button on the side. The page also needs to change between content pages. Currently I am trying to get the CarouselPage to work since it has the ability to load content pages whereas the CarouselView does not. Also, I cannot use the latest version of Xamarin.Forms (2.5.x) because I must support Android 6 (Marshmallow), so I'm stuck with 2.4.0.282. I have looked at many custom alternatives, but they all require Android 7 or higher which will not work, also, sometimes they say they'll support a lower version of Android, but something they reference requires a higher version.
Any thoughts on how to accomplish this task?
Thanks,
Daniel
Hi everyone, In my app have a feature like take photos for profile picture. I am using xam.plugin.media 3.02v for taking photos, it's working fine but after updating my xcode to 9.2v it's getting crashed. After taking photo and click "use photo" tab in my ipad, app is crashed. I have used 'NSCameraUsageDescription' and 'NSPhotoLibraryUsageDescription' permissions but still getting crashed. Please suggest any idea for crashing of app. Thanks in advance.
So I want to learn xamarin forms, but there are bugs like this everywhere.
I go and select new project > cross platform >cross platform app (xamarin forms) > select blank template > ui tech: xamarin.forms and code sharing strategy: .NET standard
So, I go to the mainfile xml to generate a new button.
I can generate some code like this
<Button Text="dd"
Clicked=""
but when Im writing "clicked", intelligense should give me the option to autogenerate this code
Clicked="Button_Clicked"
so that function gets created on the background.
This works properly on the shared project strategy, but on .net standard strategy it doesnt work.
Is there something that can be done about this?
I am using this [Xamarin Forms Library of Google maps: https://github.com/amay077/Xamarin.Forms.GoogleMaps/. Now I have properly integrated it on my project. My question is, is there a way I can include streetview on my project or at least open the googlemaps streetview on the device when a button is clicked. I can't seem to find a good tutorial for this. I'm quite new to xamarin. Thanks in advance
How can I detect when a user enables smart invert on iOS in Xamarin.Forms? And how can I tell iOS not to invert my app that I already set it?
Hi all together,
i create a new solution in Xamarin.Forms.
As i select UWP as StartProject the Debugger is missing all BreakPoints.
In Android the Debugger is working as expected.
Any ideas?
Thanks

Have anyone already configure the linker to work properly with the Microsoft Unity container?
I have an app that is currently in production but at for now i've only use "SDK assemblies only". So i'm trying to reduce the size of this app and linker is the best option but i'm not getting to make it work.
I've already make a test: created a new Prism.Unity app, with the Prism Template Package and the only change that i made was set link to full mode...the app crashes as well.
The error message:

Hello everybody, I have problem initiating an isolated services, sometimes known as Long Running Services. The process crashes on start. The same process starts and operates with no issues if run without IsolatedProcess attribute.
So I have discovered the issue is with the top part of the code, please look at the code below;
namespace AppClient.Droid
{
[Service
(Name= "com.Location.App.SimpleService",
IsolatedProcess = true,
Icon = "@drawable/icon",
Process = "com.Location.App.SimpleService",
Label = "SimpleService")]
public class SimpleService : Service
{ ...........}
Please note that com.Location.App is my package name set into Manifest xml file - <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.Location.App"
I initiate process from MainActivity during application load and the service should remain running even if UI of the application is closed.
I will appreciate for your time.
I have successfully implemented Control template for my app and added Commands as Template binding.
But now i need to show busy indicator in control template. i have IsBusy bool in my view model base.
When i try to create bool or Boolean Bindable property in my Main Page it throws errors.
I am following xamarin "Binding from a ControlTemplate"
public static readonly BindableProperty IsBusyCommandProperty = BindableProperty.Create("IsBusyCommand", typeof(bool), typeof(MainPage), null);
Error comes from bindable property
System.TypeInitializationException: The type initializer for 'Myproj.Views.Navigation.MainPage' threw an exception. ---> System.ArgumentException: Not a valid default value
What's the preferred way to name iOS abstractions? Let's say I have a iOS-service of some sort. It makes sense to prefix it with iOS, but to follow the c# conventions I should case it like IosService, but that looks like an interface.. What do you guys usually do? Suppress the warning, follow the c# convention, or some other variant?
Hi
Is there an event fired when an iOS app closes, which I could use to consume an api call?
I don't want to make the api call when the app enters the background by pressing the home button.
Only want to call it when a user swipes the app off/ force closes.
thank you in advance
Due to version conflict I did Uninstall and then Reinstall all of the NuGet Packages in .Droid and Portable project accordingly.
