+This is template for DlangUI Android project.
+============================================
+
+Copy this directory to some DlangUI project's directory to allow Android builds.
+
+Currently only armv7a architecture is supported.
+
+
+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 
+
