@simon.vergauwen Are there any particular proguard rules I need for Arrow's retrofit adapter? I'm getting 
java.lang.IllegalArgumentException: Unable to create call adapter for ta.b<d2.a>
after minifying my code...

I added those rules, and I'm still getting that error...
I'm using the 
Either<CallError, T>
form...
s
In that case there might be some other issue with your proguard config
d
It does say something about a call adapter and that's the only new call adapter I used in this version.
AND I added Arrow...
s
Try disabling r8 full mode. That will confirm if it's the issue I linked above or something else
d
yup, it works w/o full mode @stojan

The arrow adapter used to work without any additional config. With r8 full mode the issue is because of Retrofit. So it's probably something with your code. Maybe check the proguard config for any JSON parsing lib. You could also search this channel, there was a similar discussion some time ago, it might have some additional information
d
Ok, thanks! At least I know it works for others... I'll try to see what's causing this on my side.
It seems that to get the retrofit arrow adapter to work with r8 full mode, I needed to add 
-keep,allowobfuscation,allowshrinking class arrow.core.Either

Didn't we put this in the documentation? 🤔
d
Where? I don't really see a section on Android?
s
I thought it was added somewhere in the documentation of the retrofit adapter, but I might be mistaken. It would be welcomed though! And/or is there a way to bundle this with the library?
s
Yes, there is a way to bundle it
d
There isn't any documentation in the github repo... and in the Arrow docs there's just a link to it with no comment.
