I do not know which code is wrong you have to find the code which cause the error.

you can ctrl+k,ctrl+c the possible code and find out which code cause the error.

Hi, so basically the app is pretty simple and its was working fine, but i wanted to add more features and decided to add a Menu to handle the different options to redirect to new screens within the app, but when i added the app started crashing and now it gaves me this error and im not quite sure how to solve it.

I tried using this TUTORIAL obviously modifying it in order to make it work for my app, but still no results, yo can find a demo of the app HERE

Hamburger Menu/Side Menu is something like this

Hi @JessieZhang-MSFT so what i do is,

1: Open the Project
2: Clean And Rebuild the Solution
3: Then Start the Application and wait for like 5 mins or more, the android emulator screen should show the app home screen but instead it shows the mentioned error, you want me to record a video maybe ?

Hi, NeidennX-8393. For the hamburguer menu, try using Xamarin.Forms.Shell as the application template. Shell provide the fundamental features and reduces the complexity of mobile application development.

Check the doc:

I'm sorry to reply you so late because of illness. I tested your latest demo, but I still couldn't reproduce this problem.
After more than ten minutes, the app still works normally.

HI @JessieZhang-MSFT So sorry to hear that, hope you're getting well, ok is weird but try deleting all the versions you have of the demo from your PC, then download it again and extract it to a different folder, that should do the trick, and let me know if you're able to reproduce the issue.

It is a pity that the problem has not been repeated. What device did you test it on?
I tested on my emulator (pixel 2 Orel 8.1).
