.Net 10 app craashes at startup with Fragment error

[marcojak]

Description

If I update my app to MAUI 10 and .Net 10, I get the following error:

java.lang.IllegalArgumentException: No view found for id 0x7f0900fd (com.hightouch.safenotes2:id/italic) for fragment NavigationRootManager_ElementBasedFragment{5e202cf} (7ca5a27f-a5e3-4339-97ec-fd5a6be67fb7 id=0x7f0900fd)

As a workaround, I have to clean the solution, uninstall the app from the simulator and then it might work.
If I go back to MAUI 9 and .Net 9, I don't have the issue anymore.

Steps to Reproduce

I simply run my project and after the splashscreen I get the error instead of seeing the first page of my app.

If I go back to .Net 9 and MAUI 9, then it works.

It's impossible to reproduce. It's such a random bug.
If I clean and rebuild then it works but then it stops again with a random pattern.

Maybe you log metrics somewhere? Could you share more details (stacktrace etc.)?

[marcojak]

Sure, here is the StackTrace. Just as a note: When I get this error. I clean the solution, remove the bin & obj folders, build the solution again and it works. so it's not the code. Anyway here is what I get:

`Java.Lang.IllegalArgumentException: No view found for id 0x7f0900fd (com.hightouch.safenotes2:id/italic) for fragment NavigationRootManager_ElementBasedFragment{e8564e0} (5ce0d7e9-7f86-493d-95ec-0e9af8d9addf id=0x7f0900fd)

Thanks for the details. The crash occurs during FragmentStateManager.createView() when the navigation system tries to inflate a fragment but cannot locate the required view resource. Maybe could be related with dotnet/maui#24774
@jonathanpeppers Thoughts?

[Cheesebaron]

This is not happening only for MAUI, it also happens in a plain .NET Android App and only a rebuild fixes this.

[jonathanpeppers]

Can someone comment if this is happening in .NET 9 or only .NET 10?

I cannot consistently reproduce. But this is on .NET 9. I don't think I seen it on .NET 10 RC1/RC2.

@Luckre can you edit your post and share that as a file? It's 10 pages of scrolling.

I asked chatgpt about how to fix it and it noted that the mobile device that caused this error is one of the Chinese brands that are aggressive against apps that uses memory like my image editing app

Some manufacturers are notorious for aggressive memory and background process management:
Huawei / Honor: EMUI aggressively reclaims memory and may interfere with fragment restoration or image decoding.
Xiaomi / Redmi / POCO: MIUI has strict background limits and may kill apps silently if memory spikes.
Samsung` (One UI): Generally stable, but older models or budget lines (A series) may crash under bitmap pressure.
OPPO / Vivo / Realme: ColorOS and FuntouchOS often prioritize battery and memory over app stability.
