il2cpp support

[NumanDogruay]

I will try Script Backend il2cpp Not working on Android and Ios.
When try on Android:
It's not send debug to editor. I connect with breakpoint it's give Culture error on Debug.log side
When try Ios:
On load give error like
Exception: Encoder error - BadArgument
at Mumble.OpusEncoder.set_EnableForwardErrorCorrection (Boolean value) [0x00000] in :0
at Mumble.OpusCodec.InitializeEncoderWithSampleRate (Int32 newSampleRate) [0x00000] in :0
at MumbleTester.Start () [0x00000] in :0

I thing can't load static lib Unity on il2cpp.
It's working on mono Script Backend but Ios only selected il2cpp.

Any idea?

This plugin doesn't support ios to the best of my recollection. I also haven't tested il2cpp on Android, but I'm surprised that it doesn't work out of the box. Unfortunately, I really can't spend time working on this plugin anymore, but if you have any more errors / tests I can maybe point you in the right direction.

I build opus with https://trac.pjsip.org/repos/ticket/1904 this description and xcode saw library i thing only problem on il2cpp on unity..
Unity says
"When using the IL2CPP scripting backend, you can use C/C++ source files as plug-ins and Unity compiles them along with IL2CPP generated files. This includes all C/C++ source files with extensions .c, .cc, .cpp and .h." on this page
https://docs.unity3d.com/Manual/AndroidNativePlugins.html

Do you thing using this is work?
Thanks for reply.

[BananaHemic]

I think that using the opus c and .h files could work, but I think it'd be making your life more difficult. I think the easiest solution would be to just use the compiled opus libraries that are already in the repo.

Any new update on this issue?
I have this issue in unity2019.4.5 il2cpp android build

[BananaHemic]

I haven't looked into this personally, if you try something and hit an error you're welcome to post it here and I can take a look

Thank you for response,
In unity editor everything is Ok but after build for android with IL2CPP scripting backend, running example scene on device gives this error:
DllNotFoundExeption: Unable to load DLL 'opus-1_3': The specified module could not be found

[BananaHemic]

Hmm, I'm seeing other people with some similar issues in other repos. I think we need to change the DLLImport. You might want to change this line so that the __Internal name is being used for IL2CPP...Not sure if that will do the trick however

I did this and now I get error in build process(Building Native Binary with IL2CPP) :

Seems that that did not do the trick. What arch is your android phone?
Honestly, what we might want to do is look at another unity asset that uses opus, like Photon, and see if they have the same problem and if not, why.

Good news, DllNotFoundExeption solved! I used the opus android plugin in this repo: https://github.com/TyounanMOTI/UnityOpus
Build Succeeded.

Bad news, new error:
ArgumentException: Get method not found for 'Name'

[BananaHemic]

I had meant Photon Voice, not just Photon.
Did you just change out the .so? If so, which one?

The error you listed looks like unity stripped something out that it should not have. You can change that in PlayerSettings > ManagedStrippingLevel

I removed files and folders in Plugins>Android and copied unityopus.aar there. Also changed "pluginName" in "NativeMethods" class to "unityopus", like this:
#if UNITY_ANDROID
const string pluginName = "unityopus";
#else

I disabled ManagedStrippingLevel but the error still remains.

Do you have any obfuscators in use? It seems like the serialization on this line is using reflection, which fails on "Name" for some reason. Seems like a lot of people have trouble with protobuf and il2cpp. You might want to try the solution listed here

Unfortunately, adding that link.xml did not solve the problem. I think the problem is .NET version. Unity has removed .NET3.5 from Api Compatibility Levels and now it is forced to .NET4.x. Maybe we need protobuf-net.dll that targets .NET4.x. I searched but I could not find one. Hope you can help.

[BananaHemic]

I don't think so, the error you got really looks like either IL2CPP is not generating some needed code, or IL2CPP is stripping something needed. I think a NET version difference error would look quite different.

For next steps, I think you want to figure out which of those two possibilities it is. You might want to write some reflection code yourself to see which fields are available. Sorry I can't be more helpful
