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

Am I sleeping? Can we develop UI applications for Android on D? It's great!

Yes, and the same code may run on both desktops and Android.

Forgot to add that DerelictFT patch is required for DlangUI/Android.
(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.

DlangUI Tetris example now works ok on Android (arm, android4.4+)

You can download it here:

I was late, but I have since gotten this taken care of, so it's all golden.

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.
