Game crashes when joining on Android 11?

[jlb87720788]

Hi there,

For some players, the game crashes when joininga game when using an Android 11 device, maybe Android 10 also crash.

Unity: 2020.3.48f1
NGO: 1.5.1 (Transport: 1.3.4)
Relay: 1.0.5(Transport: 1.3.0)

But I just use unityTransport and the protocolType is Unity Transport ,not Relay. Then some android crash. Many devices work well.
The crash log is:

If you are using Unity Relay services and QOS, then I would try updating to v1.5.1 of com.unity.collections and see if that resolves your issue? The crash information provided seems to be from a release build which is difficult to determine specifically where the issue is coming from, but I do know there is a known issue with unity QOS services and android that has to do with a bug that was in the earlier version of the com.unity.collections package... v1.5.1 of com.unity.collections resolves that issue.

Otherwise, if that is not the issue then if you could make a development build and see if you can replicate the crash... the log output from that should provide more information...

Alternately, you can try disabling (if enabled) code stripping to see if that is part of the crash as well...if it doesn't crash with code stripping turned off then check to see if you have the multiplayer tools package installed...if so... try removing that package and rebuilding with code stripping turned on and see if that resolves your issue?

Apologies for sort of throwing out several possible ways to get more details...any useful information I could derive from the log you provided would be located in the portions of the log that look like libil2cpp.0x<some number>(Native Method)...which in a development build should provide more details than that.

Hello, I found that it is work well in 64-bit android phone, But crash in 32-bit android phone. and my QOS in relay 1.1.0. the com.unity.collections is 1.2.4 in qos.

@jlb87720788
Ahh, yeah the QOS -> Collections crash was specific to 32 bit Android builds.
Could you try upgrading your com.unity.collections to v1.5.1?
In the Package Manager, select "Add package by name" and enter:
Name: com.unity.collections
Version: 1.5.1

Then see if you still get the crash on 32 bit Android builds?

I have the same issue, its not related to relays. It's when Android is built with IL2CPP, and tries to receive a customNamedMessage.
I made a very simple project where all it does it connect to a dedicated server, and the server sends a customNamedMessage on connection. It immediately makes the android app crash. If the android app is built with Mono there is no problem.

Another strange thing is that if Script Debugging is enabled on the android build, it will not crash.

I am on Android 13, 5.10.157-android13-4
But i had other people using my netcode asset report issues with android they may be on different versions.

[Marc477]

So I made a test project here that crashes Android: https://github.com/Marc477/AndroidTest

I'm not the only one with this issue, I published a Unity Asset store asset using Netcode and many people reported that issue to me before I had to investigate.

This project was uploaded with 2020.3.37 so that its easier to test on other unity version. but i have the bug on all unity version and on all netcode version that i tried. (I tried latest of 2021, I tried Netcode 1.4.0, 1.5.2, 1.3.1)

Before building, in the game scene, change the connection address to the IP of your server (TheNetwork prefab).

Here are my build settings for Android

Here are my build settings for my linux dedicated server.

What i did is create a Digital Ocean droplet and run the dedicated linux server on it.

Then I make an android build and click on the test button a few times, until it crash.

Remember that it works in Mono, and it also works when Script debugging is enabled.
It doesn't work in IL2CPP without script debugging.

[Marc477]

So after further investigation, in my project, if i change target architecture from ARMv7 to ARMv64, its working in IL2CPP !!
So there is definitely a problem that needs to be fixed with netcode on Android IL2CPP ARMv7

EDIT: I do NOT use the com.unity.collections package in my project and installing it (1.5.1) does NOT solve the problem.

@Marc477
What is your project's code stripping level set to for your ARMv7 build?

[Marc477]

I tried disabling code stripping but it doesn't seem to make a difference

[NoelStephensUnity]

Ok, I am going to build and test the project you provided.
👍

@Marc477
Just as a side note, you will want to dispose of that FastBufferWriter after you send the message...
Easy way to handle that is:

        using (FastBufferWriter writer = new FastBufferWriter(0, Allocator.Temp, 1024))
        {
            network.CustomMessagingManager.SendNamedMessage("action", NetworkManager.ServerClientId, writer, NetworkDelivery.Reliable);
        }   

or...

        FastBufferWriter writer = new FastBufferWriter(0, Allocator.Temp, 1024);
        network.CustomMessagingManager.SendNamedMessage("action", NetworkManager.ServerClientId, writer, NetworkDelivery.Reliable);
        writer.Dispose();

[Marc477]

That's right. Thanks for pointing out. I do dispose all the buffer in my main project I just forgot to dispose it in this test project. So it's probably not what cause the Android Crash.

I did a push to fix that.

[NoelStephensUnity]

Yeah, definitely not why it is crashing... but just making sure... finally have things setup and building to see where it crashes.

[Marc477]

So does it crash for you ?
