# ktor

[Vincent Barthelemy]

Hi 🙂 I have been playing with Kotlin/Native for Android (building final executable binaries that run on Android devices) and I was wondering if there is a way to use ktor server for androidNativeArm64.

I tried to use ktor-server-cio but I run into dependency resolution error (I guess Ktor server CIO does not support android native as presented in the Supported platforms documentation).
I found this related question with an answer mentioning a "partial support" but I suspect that "native/android" was referring to "native targets and/or android (jvm) target", not "android native target".

Does someone managed to make ktor-server work from android native binary and/or have some pointers I could look at? 🙏

We have some work in progress for introducing native android https://youtrack.jetbrains.com/issue/KTOR-7289/Support-androidNative-targets

Great news, thanks a lot for the information and the link 🙏

Follow-up - in case someone might be interested in running ktor on android native -

• the initial support for android native targets by whyoleg worked like a charm (at least for my use case)
• I have just modified the publication script to publish androidNativeXXX artifacts

• Running ./gradlew publishToMavenLocal to publish artifacts locally make it possible to depends on io.ktor:ktor-server-cio and io.ktor:ktor-server-server from android native source sets.
• Pushing the final binary on an Android Emulator and starting the server worked perfectly (at least for a simple "Hello World" exemple)
• Forwarding ports with adb made it even possible to reach the web server running on the android emulator from a browser running on the host machine ! 🎉
Thanks again @Bruce Hamilton for pointing me in the right direction! Made my day :)
