The adapter always returns null when using Android's R8 minification

[Paul-Etienne]

Hello, first of all, I don't know if you're still maintaining this repo, but in case you do, here's a problem I'm facing at the moment.

I was using your adapter class to convert Retrofit's responses into Kotlin Result<T> type, which was working perfectly in debug mode, without R8 enabled. But I'm now trying to build a release version with R8 enabled, and as soon as the response reaches the adapter, I always end up receiving a null value.

I'm guessing some Proguard rules are necessary to make your adapter work, I'm still trying to figure out which rules to add though. I assume it's tied to the reflection part. I'll post here if I manage to find rules that work, otherwise if you have time you can have a look as well.

I've just realized I don't necessarily need this adapter returning Kotlin's Result<T> type. I've just noticed I can simply use Retrofit's Response<T> type thanks to that SO post. I didn't need to change much code in my application and this type is compatible out of the box with Proguard's minification, so I'm just gonna go with that.

I won't spend more time looking for a Proguard rule that would fix this repo's adapter solution. I'll leave the issue open in case somebody really needs to have a Result<T> type and have R8 enabled.
