Not difficult, but it hasn't really been done yet.  I don't 
anticipate JNI causing much of a problem, but I need to look into 
it more.


I'd rather create all the complex stuff in D and either use it 
natively through java(I need a UI).


If it is workable, can the same be said for IOS(just recompile 
the D source to the IOS architecture then use it in an IOS app 
for the ui)?


Dan would have to answer the question of how well his iOS support 
integrates with Obj-C and the iOS GUI.


Mobile support is in alpha, meaning it's mostly been used to run 
a bunch of unit tests in the background.  I hope to release a 
beta for Android in the next couple weeks, along with JNI 
integration and sample apps.  Once that's done, you may consider 
using D for such an app, if you don't mind using a beta.

I've added basic Android support to DlangUI library recently.

http://forum.dlang.org/thread/cdekkumjynhqoxvmg...@forum.dlang.org

DlangUI is cross platform GUI library for D.
Your source code will be compiled on Windows, Linux, Mac and 
Android.

I hope Android backend will become usable soon (still need to add 
support of timers, text input (with onscreen keyboard), 
animation, user messages).


iOS support will probably be added in future.

Depending on your budget, you could also look at Corona - Lua can 
call D easily.


I haven't used on Android, but Qt QML may be worth a look (D 
bindings to QML).



Wrt to D on android I would try porting some existing code and 
see how that goes.  I think stuff seemed to work but because you 
don't yet have so much company then it may be hard to be sure you 
might not hit some problems till you try.

Short answer is it should work: see "Alpha support for mobile" links on
http://dlang.org/download.html

Joakim has been pushing Android support and I've been working on getting
iOS into the core language.  The caveat is that both are alpha support
and it is hard to predict when they will be first class D citizens.

Speaking for the iOS support, the downloadable compiler is based on
2.068 (LDC 0.17.0) and will move to whatever LDC supports after 1.0.0 is
released.  I don't know of any problems at this stage, as long as you
just want to side load your app.  Submitting to the App Store is another
matter.  It has not been done yet and Apple's requirement to include
embedded bitcode is missing currently.

Anyone?


If you're treating the Android/iOS applications as purely 
"client-side", then there's no reason why you can't create a 
"server-side" application in D using something like vibe.d and 
then passing data between clients and servers using JSON or 
similar data interchange formats. That way,you only develop the 
main server-side application in D, and can communicate with it 
using any other language (Java/C#/Swift) on other operating 
systems and devices.
