Cannot build ofxLua on Android Studio

[cuinjune]

I can build an empty OF project without problems but when I add ofxLua, I cannot build the project. (I used Project Generator to create a project)

Here's the screenshot of errors I get:

Any advice or guidance would be greatly appreciated.

I figured out how to fix this error.

Add the following code in ofxLua/libs/lua/luaconf.h file: (e.g. in line 75)

#if defined(LUA_USE_ANDROID)
#include <android/log.h>
#define lua_getlocaledecpoint()    '.'
#define lua_writestring(s,l)        __android_log_write(ANDROID_LOG_DEBUG, "LUA_PRINT", (s))
#define lua_writeline()             __android_log_write(ANDROID_LOG_DEBUG, "LUA_PRINT", "\n")
#define lua_writestringerror(s,p)   __android_log_print(ANDROID_LOG_ERROR, "LUA_PRINT", (s), (p))
#endif

And add the followings in ofxLua/addon_config.mk

android/armeabi:
	ADDON_CFLAGS += -DLUA_USE_ANDROID
	ADDON_SOURCES_EXCLUDE += src/bindings/desktop/% src/bindings/linuxarm/%
	ADDON_INCLUDES_EXCLUDE += src/bindings/desktop/% src/bindings/linuxarm/%

android/armeabi-v7a:	
	ADDON_CFLAGS += -DLUA_USE_ANDROID
	ADDON_SOURCES_EXCLUDE += src/bindings/desktop/% src/bindings/linuxarm/%
	ADDON_INCLUDES_EXCLUDE += src/bindings/desktop/% src/bindings/linuxarm/%

In Android Studio, the exclude flags had no effect on the project (maybe a bug) so I had to manually remove the 2 folders (desktop, linuxarm) from ofxLua/src/bindings directory.

Also, to make Android Studio read the C flags from the addon_config.mk file, I had to add the following code below cppFlags.addAll(addonCppFlags(abi, ofRoot())) in build.gradle file.

• CFlags.addAll(addonCppFlags(abi, ofRoot()))

After the fix, I could successfully build and run ofxLua project on an Android device.

I've rolled your suggestions into the feature/android branch. Can you check that it builds for Android? The AS project fix steps are included in the readme.

Also, if those project issues are related to the OF ProjecGenerator, I suggest opening an issue with the OF PG repo.

Closing for now.

The feature/android branch is merged now. Please test it when you can and we can go from there.
