Would you mind posting your example code? I'm supposed to be exploring using D on android myself next week and a little kick to help get started would be cool; I've never actually done any android stuff.

As I understand it though, you aren't supposed to use native code for the bulk of the app which sucks. But still some D is better than no D.

I don't mind, but the code is currently Java + D without any Android. I can post it in such state, the only thing that keeps me from moving it to Android is absence of D compiler with ARM back-end (though I'm sure it exists and I have even seen some articles about building D for ARM and Android).

Concluding, I can post the could if you like, or I can first try compiling it for ARM :-)

You're not supposed to use native code in Android, right, but many companies do. The company I work for uses C++ in order to make project cross-platform between iOS and Android.

I just came here to ask same question :D

whatever's easiest for you. I have an arm cross compiler targeting the raspberry pi, not sure if that will work for the android device or not, I'll try it later (the device arrived yesterday, but I haven't had much of a chance to play with it yet). But I've never done JNI before either, so I'm starting more or less from scratch here.
