General programming discussion • How to setup environment for android development with Gradle and Kotlin

Hi, I'm trying to create an Android app on my RPi 400, but I find setting environment up hard.
Sorry if this a wrong forum.

Android Studio is out of the question, because it's too heavy, so tools have to be installed manually.

My steps were:

1. Installed sdkman! and then Gradle and Kotlin using it.
2. Installed command-line tools (36) only as many guides have suggested, updated the PATH, and then using the sdkmanager tool I've installed the build-tools (36), platform-tools (36.0.2), and platform (36) packages.
3. Initialized a minimal application project using Gradle, applying Android Gradle Plugin and Kotlin plugin to it. Building was successful..

I want to make a GUI app so want to see what's going on, but adb (Android Debug Bridge) doesn't work... First of all, it's an x86_64 app (probably because no one cares), so it's running through box64 that outputs these warnings before running and then I get a SIGSEGV:
After box64's output, the adb itself outputs:
There is no log, btw. Maybe I did a bad job, but I couldn't find anything useful to help me.

• Tried using the apt package. Installed adb (then android-platform-tools, uninstalling previous), and the daemon now starts.
• Enabled USB debug on my phone and connected it to Pi, but it doesn't list in adb devices.

Figured that maybe it's something to do with SDK and adb version incompatibility (eh..), so I've installed complete SDK through apt (android-sdk android-sdk-build-tools android-sdk-helper android-sdk-platform-tools) as someone on the forum had suggested, but still no luck as now the project build fails because of unsigned licenses. But there is no tool in apt to sign them!

Now I'm thinking that maybe Pi just failed to register my phone as a device.. But I can't be really sure at this point, as I'm getting very upset with how much time I've wasted on this...
