[Android-tools-devel] Does this thing actually work?

Whoops, forgot to mail to the list. Also where I say "Android's toolset" I mean "Debian's Android toolset".

Then what do I do? I'm not using any IDE, nor am I using Kotlin. Once again, my project is here:
https://github.com/fluffrabbit/debian-android-simple
I also started a forum at mobilegamedev.org where I hope to talk about this stuff in the future with people who may be new and willing to learn. Is there a straightforward way to build using Android's toolset? Paul seemed to provide one, but for some reason it's not working and it's causing me a little anxiety because it is not hard at all to build (for example) a C++ program for Linux or Windows from Debian or Ubuntu.
Thanks for your patience with me.

Thanks for trying out the packages.

Android SDK is in fact only the metapackage `android-sdk` and additionally `android-sdk-platform-23`. We mostly focus on maintaining them. If you tell your IDE or Gradle to use `/usr/lib/android-sdk` as the SDK plus the upstream Gradle plugin, you should be able to build something.

However, for now we only maintain one SDK Platform (23) and one version of Build-Tools, so you must configure the project to use them. We are trying to package a more recent SDK Platform, but we will unlikely maintain multiple versions of anything.

The Gradle plugin we packaged as well as `android-sdk-helper` is just a workaround to let you build a project that skip the configurations mentioned above. Unfortunately any recent versions of them requires Kotlin which is being worked on. As of now the Gradle plugin and Gradle itself is terribly outdated so I don't recommend using them.
