What are the differences between

HttpClient(Android)

and

HttpClient(OkHttp)

with regards to

ktor-client

?

Mainly minimal supported android version

There’s no difference in the underlying implementation? Why wouldn’t we then always use the one that supports lower version?

There are https://ktor.io/docs/http-client-engines.html

Yes, I went through that. That doesn’t really answer my question. They only say there’s

CIO

,

Android

and

OkHttp

engines that can be used on Android platform. I’m currently using

Android

engine and I want to switch to

OkHttp

for specific reasons. Are there some downsides of doing that? Performance impact, behaviour changes, etc.?

Behaviour should not change apart from bumping into unsupported android/jvm versions or http features (as listed in the linked tables)

Thanks for the information. OkHttp engine wraps OkHttp, do you maybe know which library Android engine wraps?

Native android http client from sdk

Thank you

You're welcome

Also, you can find the discussion about difference between those two engines here.
