okio VS kotlinx.serialization

I am involved in the development of Android application which is a rather "thick" mobile client for a Web service. It heavily communicates with the server but also has a lot of inner logic too. So, I decided to use some features of Google Guava library to simplify development process. Here is a list of features I'm very interested in: immutable collections, base utils, collection extensions, functional programming sugar and idioms (common.collect and common.base), primitives utilities (common.primitives), hashing utilities (common.hash), concurrent utils (futures and AsyncFunction). Things I don't want to use in Android: common.cache (see question below), common.eventbus (we have better Android specific libs for this, such as Otto), common.io (we can use okio for Android now).

Yeah Kotlin's own standard library is a lot smaller than Java's currently so you'll need to use something third-party for this. Okio is a popular option https://square.github.io/okio/ it has a Buffer type which is pretty similar to Java's ByteBuffer

Use okio, it is Multiplatform now. I use this for my own library KStore

For networking, file IO, and streams in general, there's Korio and for Java; for just networking, there's LiteNetLib for C#; for what looks like data streams in general, there's Okio also for Java; and Tokio for multi-threaded IO in Rust.

Okio is nice for input/output streams, and sockets.

Sounds like you want https://square.github.io/okio/

On JVM, there is plenty of existing solution already on for multiplatform uses I'd suggest checking amazing Okio library by Square, that seems to cover most of basic use-cases.

I think the main multiplatform library for I/O currently is okio, https://github.com/square/okio. As for compression, you should probably create an expect class for the compressor and use platform specific calls for actual compression. Take a look at https://kotlinlang.org/docs/mpp-connect-to-apis.html.

Have you tried this:? https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md

Regardless, I followed the documentation to register List for polymorphic serialization and my static code analysis does not seem to be happy with it.

I think kotlinx.serialization might come close, but looks like custom Encoders and Decoders are still experimental.

This example will not work on a multiplatform project. you are using gson, gson runs only on jvm, you should use https://github.com/Kotlin/kotlinx.serialization for the json parsing

This is the issue to +1 https://github.com/Kotlin/kotlinx.serialization/issues/1931

Fun fact, kotlinx.serialization had a release just recently which makes it come with some bundled proguard rules to make this experience easier. Yes you'll still have issues if you're using things via reflection and try to serialize things that proguard deemed unused and removed them, but it's a step forward https://github.com/Kotlin/kotlinx.serialization/releases/tag/v1.5.0-RC

Kotlin Serialization

Kotlin Serialization is also a newer option, but doesn't have as much traction.
