When I am running to make the Apk in GitHub I got the error. As I am building the Apk in GitHub. There is no way to define something inside manifest as it is building every time fresh. All I can do is inside the Config.Xml file. After Adding android:exported="false" to it, also getting same error. Both images for this question reference attached here. GitHub Error and Config.Xml. Help will be appreciated.

I am trying to create my first React Native application. I have a login screen from which I want to navigate to a register screen if users want to sign up.

To achieve this, I was thinking of opening a modal above the first screen (login). I created the following:

I have this listener:

I have a column with a list of countries. I wish to delete all rows which do not have any of the countries listed in arrchoices. (i.e. I want to keep all rows with these countries). My data has about 4,000 rows. My macro ends up deleting all rows instead.

I've been trying to map an array of items which is passed from my Home Component to another but I'm always getting the error restaurants.map is Undefined. I fetch the data from Yelp and store it in a State(Home Component), then I pass this to another component, retrieve it through props and try to map through it(RestaurantItems Component). Please help. I have attached the code of my two components..

Home Component

As you can see in the image below, I have to give some top margin in order to "not" hide my half of the content under the navigation header, isn't header supposed to be a "safe area" for the below content, to be on the safe side I provided the SafeAreaView but still my content goes under the Header and unfortunately I have to give some hardcoded margin top value to avoid hiding.

The above image is when I comment marginTop.

Above image is when I add marginTop: 70

After multiple hours, google searches and trying to go back to previous code I can't get this weird Exception out of the way. So I'm open for any suggestion.

I did an update to an existing ClickOnce-Deployment Project of mine and in Debug everything works totally fine. After finishing the update I wanted to test the application in my own network as it is a multi-user app. Turns out I must've destroyed something along the way and because I didn't back-up the old code I can't do a rollback.

I added an Exception-catching code in the App.xaml.cs to write into a log, so if the users get an exception I can check the logs and act accordingly. This is where following log comes from:

Zeilennummer "8" und Zeilenposition "9" von "Durch den Aufruf des Konstruktors für Typ "MietPlaner2020.MainWindow", der den angegebenen Bindungseinschränkungen entspricht, wurde eine Ausnahme ausgelöst.". bei System.Windows.Markup.XamlReader.RewrapException(Exception e, IXamlLineInfo lineInfo, Uri baseUri) bei System.Windows.Markup.WpfXamlLoader.Load(XamlReader xamlReader, IXamlObjectWriterFactory writerFactory, Boolean skipJournaledProperties, Object rootObject, XamlObjectWriterSettings settings, Uri baseUri) bei System.Windows.Markup.WpfXamlLoader.LoadBaml(XamlReader xamlReader, Boolean skipJournaledProperties, Object rootObject, XamlAccessLevel accessLevel, Uri baseUri) bei System.Windows.Markup.XamlReader.LoadBaml(Stream stream, ParserContext parserContext, Object parent, Boolean closeStream) bei System.Windows.Application.LoadBamlStreamWithSyncInfo(Stream stream, ParserContext pc) bei System.Windows.Application.DoStartup() bei System.Windows.Application.<.ctor>b__1_0(Object unused) bei System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) bei System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

On my google searches I found this translation into english:

The invocation of the constructor on type 'TestWPF.MainWindow' that matches the specified binding constraints threw an exception.

The code of the MainWindow-Constructor looks like that

I just installed react navigation version 6 and i received below error

Attempt to invoke interface method boolean com.swmansion.reanimated.layoutReanimation.NativeMethodsHolder.isLayoutAnimationEnabled() on a null object reference

below is my code

I use a ZStack to display a fullscreen background image underneath the main UI. The main UI consists of a VStack with multiple views separated by flexible Spacers to scale down or up on different device sizes. Now I experience that the Spacers will not scale down on small devices because the background image on small devices remains bigger than the screen size and keeps the ZStack tall, see screenshot of the preview of iPhone 8. What am I doing wrong here?
