I am using xamarin forms and a tablet emulator with SO Nougat 7.0 and try to update the display size, but if the app was running before that and I enter again, the app crash showing the next message

If I open the app again the display size is correct and can see the images bigger or smaller, but I can´t get rid of the crash.

My miniprogram loads in the miniprogram studio emulator but I get this error after releasing it to the super app. The app uses web-view to link to an external site.
In preview mode i can't view the action bar icon but if I build the project in android I can see them.
In the console I have this:
LOG from device OnePlus X: Angular is running in the development mode. Call enableProdMode() to enable the production mode.
LOG from device OnePlus X: Error: Could not load action bar icon: res://back
If by preview mode you mean the nativescript preview application on your phone then you get the error because your resource is missing, as in the preview you don't carry your App_Resources folder on the device
Copy menu_black.png image to all resolution folders, since menu_black.png is not available for resolution of your respective emulator it is not visible. In tutorial they only have shown to add this image for mdpi and xdpi but that's not sufficient please add this image in all other available resource folders.
I have attached an image which shows the reply from Udemy tutor itself
I am working in a project where I am building two version of application native win32 and Windows Store App.
My rendering code is working in win32 but in Windows store app the screen is blank with clear color. I tried to debug the issue and captured some frame from Visual Studio Graphics Diagnostic tool. Interestingly the capture frame is showing full rendered screen with all objects showing (while the actual rendering window is blank)!
Can anyone give me some clue, what can be the issue?
I am working on Photo application.
In which a user can upload, view, and download pictures to and from the cloud.
For back-end I am using buddy API.
The problem I am facing is that once I choose a photo and try to upload it to the cloud it gives me 'Null reference exception' and this only happens when ran from Visual Studio (either to the device or emulator).
But once its deployed on my phone it uploads and behaves normally.
I don't know where to exactly put the blame and from where to start looking into this problem.
It fails on:
var photo = await album.AddPictureAsync(e.ChosenPhoto);
with the error:
A first chance exception of type 'System.NullReferenceException'
occurred in PhotoApplication.DLL
Having completed my Windows 8 Metro App, I'm trying to push it through a "Windows Application Certification Kit" test. It failed because my SplashScreen logo was too big. I get the following message:
App resources validation
Error Found: The app resources validation test detected the following errors:
- Image reference "Assets\SplashScreen.png": The image "c:\MyProject\bin\Release\AppX\Assets\SplashScreen.png" failed the size restrictions of 620 X 300.
However, I have reduced this size to be much smaller than this now (225 x 300), but am still getting the error. Also, when I run the app, the splash screen appears the same size (but with a much lower resolution).
Can anyone tell me what I need to do to make the program recognise the size is decreased?
The splashscreen should be exactly 620 x 300 pixels. Open the package.appmanifest file and you'll see a red error sign on the splash screen image name. You can use a transparent background to make up for the extra margins that you have to include to reach the correct size.
