I can't compile a minimalist Löve project in order to make an app for Android. I'm stuck at the "licence stage". In Debian 10, sdkmanager seems not to be installable separately (all sources I found on the internet mention or suppose some Android SDK program previously installed). I haven't found any independent executable or installer to it. I do not want to install Android SDK in order to create a licence. Since this is my first time creating an Android app, I would like to know how to insert such a licence "manually".
Command as per this tutorial
./gradlew assembleEmbedNoRecordRelease
Error:
