No loader found for resource: res://[...].kt

[elfefe]

Hey, The application build and start correctly on Android, but then i have a black screen and this error who indicate an issue when reading the kotlin files at runtime:

E/godot: ERROR: No loader found for resource: res://src/main/kotlin/com/gameoftricks/jmcity/JMAnimator.kt. E/godot: at: _load (core/io/resource_loader.cpp:278) - Method failed. Returning: RES()

I use d8 for the build:

godot {
    isAndroidExportEnabled.set(true)
    d8ToolPath.set(File("${System.getenv("ANDROID_SDK_ROOT")}/build-tools/32.0.0/d8"))
    androidCompileSdkDir.set(File("${System.getenv("ANDROID_SDK_ROOT")}/platforms/android-32"))
}

The full log error:

Hello ! Did you installed godot kotlin android export template ? I think you're using official godot one.

Hello ! Did you installed godot kotlin android export template ? I think you're using official godot one.

Do I just need to install the template ? Is there a documentation on how to use the template ? I've just tried with the template installed, it does the same ! I now have android (build, plugin, .build_version) on my resource tree, I've then reinstalled the application by clicking the android icon on the Godot editor and exactly the same problem happened.

[piiertho]

We miss the doc for this I think, we only say where you can find export template.
Download android templates here: https://github.com/utopia-rise/godot-kotlin-jvm/releases
Then, you have to install them to your godot userdir, following this documentation section: https://docs.godotengine.org/en/stable/development/compiling/compiling_for_android.html#using-the-export-templates

Thanks you, I'm using godot.x11.opt.tools.64 as engine to start godot on linux. I see in the release comments that only the zip files are built engines anything else Is an export template, what do you mean ? (asking cuz i'm using the godot.x11.opt.tools.64 ̃o.O)

Hey ! Here we go again :) I've successfully built the apk, but still the same issue ... Here is my configuration

So when the application is started, I've got a black screen and the logs loop on:

Sorry for late reply, too busy those days.
Can you try to place our export template in your userdir instead of in configuration ?

Hmm this sounds to me that you are using the official godot build? This phrase basically means that per platform we have a prebuilt editor which contains our module. So to be able to run any kotlin code with godot you have to use our custom built godot editor. Not sure if you are already using that?

[chippmann]

@elfefe Do you still have this issue or was it related to the engine build you were using?

[elfefe]

@chippmann The problem as persisted, and I could not find any solution for it.

I setup the kotlin version of godot and the Android build environment wich worked as it was compiling and installing on my mobile.

The application start but then the black screen issue persist..

[chippmann]

@elfefe I think you issue might be fixed by https://github.com/utopia-rise/godot-kotlin-jvm/pull/348 (since version 0.5.0-3.5.0). If not; please provide a little repro as I cannot reproduce this issue.
