Local Android plugin plugin {plugin name} not found error

Repost from here

I'm developing a simple Android plugin to detect whether it's running Android TV or other devices, but I keep getting plugin not found error from the frontend:

08-18 09:56:39.021 17778 17778 E Tauri/Console: File: http://192.168.1.102:1420/_next/static/chunks/_89715b00._.js - Line 651 - Msg: Uncaught (in promise) plugin android-tv-check not found

I tried several things, like changing the name to not using dashes, still no luck. I tried cargo build --release as well and ran pnpm build afterwards. No luck. Any pointers?

Did you register the plugin on the rust side? eg .plugin(tauri_plugin_android_tv_check::init()) somewhere in your project lib.rs file? You do in the repo's example but that doesn't use nextjs so i assume you test this somewhere else.

Ok, that's a silly mistake. Now I have made progress. Got java.lang.ClassNotFoundException:

I clearly have the Kotlin class there named AndroidTvCheckPlugin.kt. Do I need to build the plugin for Android?

[FabianLars]

I think this https://github.com/smbcloudXYZ/tauri-plugin-android-tv-check/blob/main/src/mobile.rs#L18 is missing the package name or something, for example our deep link plugin: https://github.com/tauri-apps/plugins-workspace/blob/v2/plugins/deep-link/src/lib.rs#L32

Works like a charm. Thanks @FabianLars
