I am thinking of it from a slightly different point of view. First, start with a plug-in that works with Android's native Gradle-based build system. This essentially would just add Clojure compilation support for Android, but doing it in such a way so that all of Android's build features now support Clojure as well. At this point, lein-droid is a completely separate project, unaffected by these changes. > > > 2.

Question: What is this Android build system that we refer to? The idea is this: Android moved from an Ant-based build system to a Gradle-based build system so that, amongst other features, it was more easily extendable. Thus the Clojure plug-in for Android/Gradle fits in with that philosophy. Some of the features that the new build system supports are differently configured debug/release builds. lein-droid also supports that functionality. Could we make lein-droid become a user-friendly shell around the Android build system? Clojure users are comfortable with Leiningen, so that's an important reason why lein-droid is essentail. However, lein-droid was created before the new build system, so it could potentially be even more powerful if it could leverage the Android build system by treating it as a library. I haven't fully investigated the extent to which this is feasible, but I think it's a good direction to go. This would decouple lein-droid from a lot of implementation details about how Android projects are built. Ultimately, if lein-droid could use what's in a project.clj file to generate a build.gradle file or configure the Gradle build at runtime, that should give use the best of both worlds: Clojure-friendly project definition and the full power of the native Android build infrastructure. For example, Leiningen profiles could map to Android build flavours. I hope this helps. Sincerely, DanieL > > 3.
