Resolved 1.0.0-exp.8: Editor 2022.2.0b8 android build crashes due to Unity.Networking.Transport error

    After building with the Default build pipeline (not the platform build pipeline for 0.51) for Android, I get a crash right at startup.

    Now I know there are multiple issues with building dots projects currently (after each build editor crashes, selecting faster (smaller) build, etc.) but I did manage to get a linux (server) build working, while the android build does not.

    I assume it is netcode related due to the reference to Unity.Networking.Transport errors I receive.

    Is this a known issue with the current editor version (2022.2.0b8) or did I miss a specific config needed to make a netcode projects work on android?

    Any help would be appreciated.

    Same problem here when building for Oculus Quest 2 (which runs on Android). But I get no error message. And I don't have Netcode or Transport installed in my project.

    I have reported it through the bug reporting system (case number: IN-18768).

    I also have a minimal repo (it crashes without even creating a custom client-server bootstrap)

    https://github.com/Occuros/DotsNetcodeBuildErrorSample

    Hopefully, that can be investigated soon, really looking forward to testing out 1.0 on a real device.

    Unity 2022.2.0b11 has fixed the player crashing when containing a subscene in the scene. When having set the compiler to IL2CPP. I don't know however if the Unity Networking error has been fixed, but maybe it's related.

    For this specific issue I already posted a fix you can apply in another thread:

    You need to replace in the DefaultDriverBuilder.RegisterClientDriver the call to new BaselibNetworkInterface with new UDPNetworkInterface.

    Code (csharp):
    1.  
    2.         public static void RegisterClientDriver(World world, ref NetworkDriverStore driverStore, NetDebug netDebug, NetworkSettings settings)
    3.         {
    4.             Assert.IsTrue(ClientServerBootstrap.RequestedPlayType != ClientServerBootstrap.PlayType.Server);
    5.             Assert.IsTrue(world.IsClient());
    6. #if !UNITY_CLIENT
    7.             if (UseSocketDriver(netDebug))
    8.             {
    9.                 netDebug.DebugLog("Create client default socket network interface driver");
    10.                 var driverInstance = DefaultDriverBuilder.CreateClientNetworkDriver(new UDPNetworkInterface(), settings);
    11.                 driverStore.RegisterDriver(TransportType.Socket, driverInstance);
    12.             }
    13.             else
    14.             {
    15.                 netDebug.DebugLog("Create client default IPC network interface driver");
    16.                 var driverInstance = DefaultDriverBuilder.CreateClientNetworkDriver(new IPCNetworkInterface(), settings);
    17.                 driverStore.RegisterDriver(TransportType.IPC, driverInstance);
    18.             }
    19. #else
    20.             netDebug.DebugLog("Create client default socket network interface driver");
    21.             var driverInstance = DefaultDriverBuilder.CreateClientNetworkDriver(new UDPNetworkInterface(), settings);
    22.             driverStore.RegisterDriver(TransportType.Socket, driverInstance);
    23. #endif
    24.         }
    25.

    Thank you @CMarastoni with these changes the build doesn't crash anymore (with 2022.11b editor version).

    Not sure if I should mark this thread as resolved, as it still requires to modify the netcode package, or wait until the package is updated with the fix?
