Hello, I've implemented initial support of Android in DlangUI. Only armv7a architecture is supported so far. You can downlowd sample APK: https://sourceforge.net/projects/crengine/files/DlangUI/ How to add support of Android to your DlangUI project. ===================================================== Copy dlangui/android/android_project directory to you DlangUI project directory. Probably you will want to change android package name in AndroidManifest.xml and application display name in res/values/strings.xml Modify android_app.mk, android_build_config.mk android_app.mk ============== Update LOCAL_SRC_FILES to include all your project's files. android_build_config.mk ======================= Update paths to Android NDK, SDK, DlangUI source directory. Default values: export DLANGUI_DIR=$HOME/src/d/dlangui export NDK=$HOME/android-ndk-r11c export SDK=$HOME/android-sdk-linux export LDC=$HOME/ldc2-android-arm-0.17.0-alpha2-linux-x86_64 export NDK_ARCH=x86_64 Use LDC cross compiler for armv7a build according instructions https://wiki.dlang.org/Build_LDC_for_Android#Build_a_sample_OpenGL_Android_app_ported_to_D

I just took his NativeActivity example and modified a bit to make dlangui's platform class implementation. I would be nice to have all Joakim's patches in upstream LDC and druntime/phobos.

(Freetype library has name libft2.so on Android) PR is submitted, but not yet integrated into DerelictFT: https://github.com/DerelictOrg/DerelictFT/pull/9 PS: Current build is using android-19 API (Android 4.4 Kitkat) due to GLES3 dependency. Will provide support of older platforms later, if needed.

FYI, for anyone facing a similar problem in the future and is hung up waiting on me to merge a pull request, the base loader in DerelictUtil allows overriding the default library names. So instead of a library like DLangUI requiring a patched Derelict package, you could do this: version(Derelict_OS_Android) DerelictFT.load("libft2.so"); You can pass multiple library names as a single, comma-separated string: DerelictFT.load("libft2.so,libfreetype.so"); Or as an array (which is what the above is converted to internally anyway): DerelictFT.load(["libft2.so", "libfreetype.so"]);

Thank you for your help! I've updated dlangui dub.json with
latest DerelictFT.

On older androids, application CatLog (available on Market) was able to store logs to file. But on latest android, app cannot read logs of other applications, and CatLog shows none useful. You can try CatLog, but if it does not work (if you cannot see any messages with 'dlangui' tag), the only way to get logs I know is to use 'adb' utility from Android SDK. Download Android SDK, unpack to some folder, use sdk/platform-tools/adb utility. Connect device to pc using USB. `adb logcat` from commandline shows log messages from device. run `adb logcat > log.txt`, then start program which crashes on device, then press Ctrl+C to stop adb logcat. Now file log.txt should contain logs with crash.Does it crash instantly or shows app GUI for some time?

Might be useful for me to port some D code for internal enterprise apps to Android that currently runs on linux (I recognise how experimental it is, but I'm okay with that since mobile is just nice to have, and not yet necessary). Will you be at dconf?

I would say it will take a week or too to make iOS backend once we have working compiler for iOS (in my estimations it will have 1K-2K lines of D code and 1K-2K lines of obj-c code. Unfortunately, I have no experience with objective C neither with iOS programming.
