If you try out the native compiler, take a look at the README 
that comes with it for instructions.

If you have a D/OpenGL app you'd like to port to Android and 
submit to the Play Store, let me know if I can help with that 
process.

 Cannot build ldc for Android according to instructions
 http://wiki.dlang.org/Build_LDC_for_Android

   git clone --recursive 
 https://github.com/ldc-developers/ldc.git
   cd ldc/
   git submodule update
   curl -O https://gist.githubusercontent.com/joakim- 
 noah/63693ead3aa62216e1d9/raw/b89d77d66a80206b4dd3d78bb10d83a7e368f3d4/ldc_android_arm
   git apply ldc_android_arm

 Patch cannot be applied to current ~master
 I've tried to checkout several recent tagged versions - doesn't 
 work too.
 Probably it's applicable only to some particular LDC version.
 What version of ldc should I checkout to apply this patch?

 (Building LDC on Windows)


It's not hard to figure out, as 'git apply ldc_android_arm' says 
it fails on dmd2/root/port.c and 'git log dmd2/root/port.c' shows 
this recent change to master:

https://github.com/ldc-developers/ldc/commit/556e3a691f72b97cce31d85740e8dc12cafc9f53#diff-2268700876655bdfa9d178b9cc466277

I've updated the gist and wiki page to take that change into 
account; simply download the new gist, as shown on a reloaded 
wiki page.

Also, I haven't tried cross-compiling from Windows, so you may 
run into other problems there.  The main one I can think of is 
that the test runner targets I added to CMake may have an issue, 
but there could be additional incompatibilities that I simply 
haven't run into on linux.  Hopefully, it just works. :)

Anyway, this is a good reason to get all this stuff merged soon, 
which is what I was looking into now anyway, although that 
particular change is from Kai's long-unmerged longdouble2 branch.

Thanks, shows that I've only tested with OpenGL ES 1.0 so far.  I 
was going to try porting one of the NDK sample apps that uses 2.0 
next, shouldn't be an issue.

I had a dub.json written up locally, but simply never bothered to 
commit and register it.  I'll do so now.

I'm trying to build native-activity sample in .d.
I have build cross ldc compiler using your instructions. When I 
have build native activity its work properly on BlueStack, but on 
my phone (android 4.2.1) this always crash and run again. Your 
app test runner work perfect and every test passed.
Application always crash when I'm using android_app.savedState.

if (state.savedState != null) {
     // We are starting with a previous saved state; restore from 
it.
     engine.state = *cast(saved_state*)state.savedState; //crash!
}

Sorry for bad english.

Don't compare against null using =, compare using is.

android_app.savedState appears to be defined here:

https://github.com/joakim-noah/android/blob/polish/android_native_app_glue.d#L56

It's a void *. So comparing against null with != is identical to !is.

There are actually cases where comparing against null with != is valid, 
and what you want exactly (e.g. comparing a string to null to check for 
empty string).

In this case, fixing the comparison is not the answer. What is happening 
is one of several things:

1. I don't know what type `engine` is, so if it's a pointer, then 
dereferencing the state member may be the culprit if engine is invalid.
2. If state is a pointer, then you could be crashing at the if statement 
(unlikely).
3. state or state.savedState isn't being properly initialized.
4. Something else (e.g. code generation error). Hope it's not this one.

I don't know what was bad but I start working on something 
different.
I managed to compile project with SDL. Using SDL c++ code which 
call my D code. It's work.
Used libraries: SDL, Assimp, FreeImage.

Hmm, I am unable to reproduce the crash with that sample app on 
my tablet running Marshmallow.  Can you try the prebuilt 
cross-compilers at 
https://github.com/joakim-noah/android/releases and see if the 
problem crops up with those too?

If you are able to reproduce consistently with some compiler, 
please file an issue with more info, such as which ldc version 
you built and what commands you used to build the app, either at 
the github repo for the sample app, 
https://github.com/joakim-noah/android/, or if you can reproduce 
with the pre-built ldc compilers, at the ldc github, 
https://github.com/ldc-developers/ldc/.
