How to use MainActivity.kt / MainActivity.java

[kislenko-artem]

Hello! Sorry for my question, but I didn't found any information for xbuild.
I write a project, and I need to call native functions for android. How can I do this?
So I need to add MainActivity.kt / MainActivity.java, but how can I link it?

Hi,

I had to do the same thing. You have to create in the repository a "kotlin" folder with all your kotlin files in it like I did it for my project: https://gitlab.com/Murmele/weather/-/tree/main/kotlin?ref_type=heads

Then you need to set the has_code variable in the manifest: https://gitlab.com/Murmele/weather/-/merge_requests/10/diffs#7a130749a4b98b0be7536bbde54cea8db971e3b5_21_29

Create a jni access point in your rust code:
