Let me try with this: https://docs.unity3d.com/Manual/AndroidNativePlugins.html
then if I can’t make it work he’s our last hope 
CsoundUnity Package (UPM) development
I tried to understand what to do, but I’m kinda lost… The problem is that the libs are not copied at all inside the apk.
Maybe a hint from Hector would be helpful!
I’ll try again with his .so libs and try to understand why they are copied (I think they are linked somehow with libnative.so)
Maybe I should rebuild the jni libs and link them with libnative.so? 
Do you think Steven could help?
This are the relevant scripts that build Csound for Android:
I’m sorry but I have no experience with this kind of stuff 
Hector got back to me. He doesn’t think he created libnative.so at all. 
He thinks it did, in which case it is probably just this. We haven’t needed that for some time, so I think libnative.so might be a red herring. Hector said he will take a look and see if he can offer any advise. Fingers crossed.
When you create the package from Unity? Can’t we simply place them there afterwards?
Really? Just the two methods?
Yeah when I build the apk for Android the libs simply aren’t copied inside it, while with Hector libs are.
Yes we can place them there afterwards but the procedure is a bit ugly since the apk has to be unzipped, then rebuilt after the copy, which requires aligning and signing again. Not something the CsoundUnity user would like doing (me too )
And at the end, I’m not sure it will work! (I used to do something like this to add some kind of assets to an already compiled application when I didn’t want to reopen an old Unity project)
I see what you mean. Hector wasn’t using the new packages system in his builds was he? Could that have anything to do with it?
No I think not, because it works with the libs that were inside his .unitypackage!
It just crashes as soon as we call GetSpoutSample
Hector was definitely using an older version of Csound than we are.
I think so. Is there method to retrieve the version?
I’m not sure how you might. Steven did mention something some time ago about creating a .aar package for Csound on Android ubt I’m not sure how far he got. One thing we could probably do is remove the calls to GetSpoutSample and SetSpinSample and just use spin/spout pointers instead. We had that working before if I’m not mistaken, but went back to using the GetSpoutSample() methods because they we cleaner. If we did that, then we could probably use Hector’s package. But it leaves us in a bad place for future release.
It should be easier to use the .aar instead of the .so, hope he managed to do it!
Indeed we should have the latest libs also on Android, so that all the platforms use the same API, and avoid having too much platform dependent code.
Finally back on this for a while!
I’m focusing on Android support, the problem we have there is that GetOutputSample crashes with this log:

So the good thing is that the build includes the libraries (I’m testing this on the latest Unity version), the bad one is that the code we are using inside OnAudioFilterRead doesn’t work on Android:
//if csound nChnls are more than the current channel, set the last csound channel available on the sample (assumes GetNchnls above 0)
var outputSampleChannel = channel < GetNchnls() ? channel : GetNchnls() - 1;
samples[i + channel] = (float)GetOutputSample((int)ksmpsIndex, (int)outputSampleChannel) / zerdbfs;
what can we do? Why the crash?
Is there an alternative method we can use on Android?
I also tried to wait until Csound has finished initialisation, but I always have the crash.
Hi @giovannibedetti. I’m not sure what the problem is. If you replace the calls to GetOutputSample() and return random floats between -1 and 1 does it still crash? Are we certain this is the cause of the crash, or will calls to any CsoundAPI method in the OnAudioFilterRead() method cause a crash?
Good point.
I just tried to remove the call to GetOutputSample on the development project (Unity 2019.3.9f1) and got a crash, so could it be something related with FMOD?

I don’t see anything in the log to indicate that Csound has compiled correctly? I would expect to see some output Csound? What about you try to compile a csd string instead of a file? If there is an error when you call performKsmps() it might be that the file didn’t compile correctly? I don’t know, just clutching at straws here…
Yes the csd is compiled correctly:
2021-01-12 15:25:29.878 22183-22216/? I/Unity: System buffer size: 512, buffer count: 4 , samplerate: 24000

2021-01-12 15:25:29.921 22183-22216/? I/Unity: CsoundUnity done init
Well the sample rate is a bit strange… but apart from this, the fact is that the crash comes when there is a computation in OnAudioFilterRead: we’re compiling the csd as a string now (if a csd has been set), and if it compiles this we set a compiledOK bool to true, and the code in OnAudioFilterRead is executed.
Are we overriding the sample rate? I thought we did, but it looks commented out:
Do you still have the source from the version @virtualHC send you? Are there any Android specific things he added that we’re missing?
Yes I can uncomment that part, I don’t remember exactly why it is commented 
EDIT: I think it’s because we’re using Params to set the control rate and sample rate, and probably this is not working
I’ll have a look at the code by Hector again to see what’s different 
EDIT: I’m having a look, but the code is mostly the same: we’re not copying anymore csds from the StreamingAssets folder to the PersistentFolder, the Csound initialisation is the same.
In OnAudioFilterRead we’re using the same getOutputSample, so I can’t understand the crash!!
I wonder if it might be worth trying some older versions of Csound to see if they work Ok? How does one go about debugging unity apps on Android? Might there be something destroying Csound at some point during the process? Or does it somehow become NULL at some point?
Actually, can you try calling performKsmps() straight after starting Csound?
