mobileapp | toggl mobile app | State Container library

This is my first time using android studio and I would appreciate your help here . I try to run my app on an emulator and while the emulator runs smoothly the app does not appear on it and when I run the app it just says Gradle build finished and stops . I'm pretty sure the problem is in the app configuration but I have no prior experience.

My androidManifest.xml

It seems like CORS error is well-known issue in the web field. But I tried flutter web for the first time ever and I faced critical error.

The code below worked well in app version when it was running on iOS device, but when i tested the same code on Chrome with web debugging from beta channel, it encountered CORS error.

Other stackoverflow answers explained how to solve the CORS issue with serverside files of their projects. But I have totally no idea what is server thing and how to deal with their answers. The error message from Chrome console was below

[ Access to XMLHttpRequest at 'https://kapi.kakao.com/v1/payment/ready' from origin 'http://localhost:52700' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. ]

So, what i want to do is to solve above 'Access-Control-Allow-Origin header' issue ONLY WITH DART CODE! Code below is what i've tried to solve these issues only with my main.dart.

I try to add AzureAppConfiguration to my dotnet core web application using the following Code:

I am working with Xamarin Forms and trying to implement a loading overlay that would display text show the spinny thing and disable buttons.

Since buttons need to be disabled when loading I am trying to use InverseBoolConverter

It works ok on iOS (gives a warning but I am too cool to care), Android gives an error instead, Error XLS0505 Type 'Helpers:InverseBoolConverter' is used like a markup extension but does not derive from MarkupExtension. and the build mechanism is not cool enough to build it, so I have a problem.

UPDATE - Issue #1 is Solved, Issue#2 is still unsolved You can view a very crude demonstration video of my issue at https://www.youtube.com/watch?v=5_6KJ0QJouM

I am building have a Xamarin.Forms app with an SQLite database using the MVVM design pattern and C#

When try to Save a record to the database from a View the update/save does not appear to be saving to the SQLite database or reflect in other Views.

I know the database Save method does work as I have created some dummy data when the application first loads (in App.xaml.cs) using the DeveloperData.cs file.

I have two issues.

(SOLVED) Issue 1 - Data not Saving to Database when I call the Save command from the MerchandiserEditPage.xaml, which uses the MerchandiserEditPageViewModel.cs ViewModel, the record does not appear to save.

Issue 2 - Changes Reflecting in other Views Once the updated data is saved to the database, how can I reflect that change in other views? After I Save a record from the MerchandiserEditPage that View is "Popped" off the stack and the user is returned to the MerchandiserProfileView. I want the updated data to be reflected in all other views on the stack. But this doesn't appear to be happening? (I tested this using hardcoded data and the same issue occurred, so problem is not directly related to issue 1)

There are many files in my project, that can be viewed/downloaded from my GitHub repository but I will concentrate on the following in this question.

• MerchandiserEditPage.xaml (View)
• MerchandiserProfilePage.xaml (View)
• MerchandiserDatabase.cs (Database Functions)x
• MerchandiserEditPageViewModel.cs x

MerchandiserDatabase.cs (Database Functions)

Should ViewModels inherit other ViewModels?

I have a MerchandiserViewModel that contains the basic properties and database functions for a Merchandiser model.

The MerchandiserViewModel has a SelectedMerchandiser property that holds the selected Merchandiser from the ItemSelected in a ListView

MerchandiserViewModel.cs

I have ViewModels instantiated as a Static Resource in App.xaml.

I am trying to set up a build pipeline for the Xamarin Android app using AzureDevops Pipeline.

The step that is causing my hair to go thin and grey is Signing and Zipaligning.

For signing, I have created a self-signed key using:

keytool -genkeypair -v -keystore keystore.keystore -alias keyAlias -keyalg RSA -keysize 2048 -validity 10000

Then I have added keystore.keystore to azureDevOps secure files location and enabled it for all pipelines

I then set the signing step in the following way:

My Sample custom control inherits from the SKCanvaView and overrides the OnTouch method. It simple prints into the Debug stream action type, however, the action type is always the type of Pressed.

From my understanding, I should get action types like Pressed, Released, Moved, Cancel. Why I'm getting only the Pressed action type?
