D for Android beta
The beta release of ldc 1.3, the llvm-based D compiler, is now out: https://github.com/joakim-noah/android/releases It is accompanied by a non-trivial sample app from the Android NDK, ported from C++ to about 1.2 klocs of D: the classic Utah Teapot (https://en.wikipedia.org/wiki/Utah_teapot), updated with mobile touch controls. This app also demonstrates calling Java functions from your D code through JNI, though most of it is written in D. There are two builds of ldc, a cross-compiler that you can use from a linux/x64 shell to compile to Android/ARM, and a native compiler that you can run on your Android device itself. As I pointed out last year, not only is ldc a large mixed D/C++ codebase that just worked on ARM, but it is possible to build arbitrarily large Android apps on your Android device itself, a first for any mobile platform: http://forum.dlang.org/thread/ovkhtsdzlfzqrqneo...@forum.dlang.org This is the way the next generation of coders will get into coding, by tinkering with their Android devices like we did with Macs and PCs decades ago, and D is one the few languages that is already there. I will write up instructions on how to write an Android app in D _on_ your Android device by using ldc and the Termux app, and get ldc into the Termux packages, a package repository for Android: https://play.google.com/store/apps/details?id=com.termux&hl=en

I'd guess that's the issue, as I haven't tested against those older versions of Android and this app links against Android API 21, ie 5.0 Lollipop: https://github.com/joakim-noah/android/blob/master/samples/Teapot/build-apk#L17 I'm pretty sure it'd work for your older Android versions if built slightly differently, as I used to support back to Android API 9 until a couple months ago: https://gist.github.com/joakim-noah/f475b0be37b3834b4e50d68996b6ee1d#file-ldc_1-1-0_android_arm-L3438 It can be still made to so but I set API 21 as the minimum, because anything older has been declining for some time now: http://blog.davidecoppola.com/2016/12/android-version-distribution-history-visualization-2012-2016/

I am able to reproduce the grey screen, with no teapot. I tried recompiling and linking the native D portion of the app against API 9, but noticed that the resulting native D library was exactly the same, with the same SHA hash. Then I remembered that I built the small Java portion of the app against API 21 also. My guess is that is what is causing the problem, since the Java source has to do a bit of setup so that both the Java and D code can share the UI: https://github.com/joakim-noah/android/blob/master/samples/Teapot/src/com/sample/teapot/TeapotNativeActivity.java This is needed because this sample app demonstrates using JNI to call the Java functions showUI and updateFPS, to send the framerate from D to the Java functions to display at the top left. I will note the Android 5.0 requirement on the release, thanks for reporting.

Hmm, is that the 64-bit Xiaomi device you mentioned in the github issues just now? My guess there would be that it's because ldc only supports 32-bit Android/ARM devices right now, and 64-bit devices like Xiaomi probably don't run 32-bit native Android libraries in their apps, though I don't know that for sure. I just tried installing the teapot app on another 32-bit 6.0.1 phone that I'd never tried before, worked fine. This is not an issue for Java, because the Android runtime compiles Java bytecode to native code _after_ the app is downloaded, but other languages have to provide pre-compiled libraries for each CPU architecture. Not a big deal as there are only really two in wide deployment, 32-bit and 64-bit ARM, with the vast majority 32-bit right now. Perhaps you can help us get on 64-bit ARM, as you mentioned in the github issues.

I found that SO link inconclusive, but I just found this blog post from a couple years ago that says that it depends on the device: https://ph0b.com/android-abis-and-so-files/ With your 64-bit device, either it doesn't list ARMv7 as a supported ABI or there's some bug that's stopping it from running this 32-bit ARMv7 library on ARMv8.

Yes, the goal is to document all the steps, like I do on the wiki for cross-compiling now, but more so because it's completely new to most and requires a few more steps than the official NDK/SDK. But the official NDK requires using or mimicking their build system and the SDK can be a bear to setup, as they give you a ton of stuff like an IDE and emulators, so this might actually be easier overall.

It's very nice to see your detailed release notes, with links to the patches. Hope we can get much of that into LDC master soon. There's not much left, the cross-compiler doesn't require any patches and the remaining tweaks to druntime/phobos are minimal. I'll get the last bits in, with the exception of that workaround in std.stdio for the regression specific to Android 5.0.

Thanks for publicizing it, looks like you've started a discussion on reddit.

I keep meaning to check out programming for Android, but as with far too many things, I never get around to it. But if I program for something like Android, I'd definitely prefer to be doing it in D. A huge thanks to you and everyone else who's worked on this! - Jonathan M Davis

Haha, I lol'ed when I just read this comment: "Ah, D only came into my field of view with the recent support on Android and I assumed it was a recent language designed for Android." https://www.reddit.com/r/programming/comments/6eqv46/comment/dif3sa0 Well, at least we're getting more of these Android people introduced to D.

Cool:
pkg search ldc
pkg install ldc
plk install vim
vim app.d
import std.stdio;
void main()
{
writeln("hello d on termux");
}
(volume button up+q)
(ESC button)
:w
:q
ldc2 app.d
./app
hello d on termux

I'm looking at 64-bit AArch64 support, where pretty much all the druntime tests pass with ldc 1.8 because of the great work of David, Kai, and others. The few failures are likely related to emulated TLS not being tied into the GC yet. I'll be working on this port this week.
