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.

if (state.savedState !is null) {

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/.
