Android IL2CPP build crashes in MetadataCache.cpp

I'm seeing a very weird crashing bug. The first time I install my app everything works great, but if I uninstall the app and install a new build, the app will crash instantly at MetadataCache.cpp line 756. Has anyone ran into this before?

I did find out that if I go into my app settings and clear all storage related to the app, that will get the app running again.

 

Yeah seeing this issue and it's stopping us from making a certification build.

 

Has the bug been reported yet because I have the same issue installing the the app and deleting the app data (see https://forum.unity.com/threads/app-does-crash-when-installing-the-app-via-apk.731876/ )

 

I just figured out that my App works with 2019.1.x but starting with 2019.2.x it does not work anymore.

 

@JoshPeterson, @SomehowLuke

Sorry guys, I haven't been able to report it yet. I was out of town for the last couple weeks. I'll try to do that early next week and I'll post the bug link here.

 

Hi Guys,

Is the problem reproducible with an empty project? or is it possible to isolate your project and share it in this thread?

 

@JoshPeterson

Hi guys, I believe I've encountered this error as well. I received the same error as the original post.

E:\Program Files\2019.1.12f1\Editor\Data\il2cpp\libil2cpp\vm\MetadataCache.cpp:755: static Il2CppMethodPointer il2cpp::vm::MetadataCache::GetMethodPointer(const Il2CppImage *, uint32_t): assertion "rid <= image->codeGenModule->methodPointerCount" failed

I've provided a bug report and attached the offending build and crash logs for both debug and release builds : http://fogbugz.unity3d.com/default.asp?1188336_qtgc3q4f37ku0dj9

If required I can provide the full project however is is over 3 gig so might have issues uploading it all.

 

Sorry for the necro, but my project suddenly started having this crash even though I didn't change any code or configuration, so I was searching frantically for a solution to this (Unity 2021.1.16f1).
NullPointerException in il2cpp::vm::MetadataCache::GetMethodPointer(Il2CppImage const*, unsigned int).

To anyone that might run into this issue, try clearing your library folder, or parts of it, before building again.
I'm still not sure what caused the issue or what resolved it, I was switching between APK builds and App Bundle builds, and suddenly this crash appeared on the final AppBundle build.

It seems related to cached build files in /Library, so after clearing all il2cpp*-folders, BuildCache and csproj files, the issue went away. Hope this spares someone a few days of debugging.

 

you solved my problem! thank you!

 

Thank you!

Same story 2020.3.16 il2cpp armv7+arm64 at first crashes in ParticleSystem and GlobalMetadata.cpp, after remove of particles start crashing in MetadataCache. But exported project always work fine after build with Android Studio, so some cache troubles explain it.

 

It‘s great！

 

Super! Thank you!

I also was switching between APK builds and App Bundle builds (between Mono and IL2CPP).
