Android gradle ndk jni build с внешней библиотекой и собственной отладкой (ARToolkit)

Question

Я пытаюсь, чтобы студия Android была моей основной средой разработки для Java и кода c/C++. Я хочу иметь возможность отлаживать собственный код.

В этом случае я пытаюсь использовать ARToolkit5 в качестве библиотеки.

Из-за некоторых примеров в ARToolkit5 у меня есть этот файл сборки.

я имею этот Android.mk файл

MY_LOCAL_PATH := $(call my-dir) 
LOCAL_PATH := $(MY_LOCAL_PATH) 

# Pull ARToolKit into the build 
include $(CLEAR_VARS) 
ARTOOLKIT_DIR := $(MY_LOCAL_PATH)/../../../../../artoolkit5/android 
ARTOOLKIT_LIBDIR := $(call host-path, $(ARTOOLKIT_DIR)/obj/local/$(TARGET_ARCH_ABI)) 
define add_artoolkit_module 
    include $(CLEAR_VARS) 
    LOCAL_MODULE:=$1 
    LOCAL_SRC_FILES:=lib$1.a 
    include $(PREBUILT_STATIC_LIBRARY) 
endef 
ARTOOLKIT_LIBS := ar2 kpm util eden argsub_es armulti ar aricp jpeg arvideo 
LOCAL_PATH := $(ARTOOLKIT_LIBDIR) 
$(foreach module,$(ARTOOLKIT_LIBS),$(eval $(call add_artoolkit_module,$(module)))) 

LOCAL_PATH := $(MY_LOCAL_PATH) 

# Android arvideo depends on CURL. 
CURL_DIR := $(ARTOOLKIT_DIR)/jni/curl 
CURL_LIBDIR := $(call host-path, $(CURL_DIR)/libs/$(TARGET_ARCH_ABI)) 
define add_curl_module 
    include $(CLEAR_VARS) 
    LOCAL_MODULE:=$1 
    #LOCAL_SRC_FILES:=lib$1.so 
    #include $(PREBUILT_SHARED_LIBRARY) 
    LOCAL_SRC_FILES:=lib$1.a 
    include $(PREBUILT_STATIC_LIBRARY) 
endef 
#CURL_LIBS := curl ssl crypto 
CURL_LIBS := curl 
LOCAL_PATH := $(CURL_LIBDIR) 
$(foreach module,$(CURL_LIBS),$(eval $(call add_curl_module,$(module)))) 

LOCAL_PATH := $(MY_LOCAL_PATH) 
include $(CLEAR_VARS) 

# ARToolKit libs use lots of floating point, so don't compile in thumb mode. 
LOCAL_ARM_MODE := arm 

LOCAL_PATH := $(MY_LOCAL_PATH) 
LOCAL_MODULE := ndkDebugModule 
LOCAL_SRC_FILES := nftSimple.cpp ARMarkerNFT.c trackingSub.c 

# Make sure DEBUG is defined for debug builds. (NDK already defines NDEBUG for release builds.) 
ifeq ($(APP_OPTIM),debug) 
    LOCAL_CPPFLAGS += -DDEBUG 
endif 

LOCAL_C_INCLUDES += $(ARTOOLKIT_DIR)/../include/android $(ARTOOLKIT_DIR)/../include 
LOCAL_LDLIBS += -llog -lGLESv1_CM -lz 
LOCAL_WHOLE_STATIC_LIBRARIES += ar 
LOCAL_STATIC_LIBRARIES += ar2 kpm util eden argsub_es armulti aricp jpeg arvideo cpufeatures 
#LOCAL_SHARED_LIBRARIES += $(CURL_LIBS) 
LOCAL_STATIC_LIBRARIES += $(CURL_LIBS) 

include $(BUILD_SHARED_LIBRARY) 

$(call import-module,android/cpufeatures) 

Эта сборка работает должным образом. Теперь я пытаюсь преобразовать это в файл экспериментального градиента Android, чтобы иметь возможность его отлаживать. Ну теперь я имею это состояние:

apply plugin: 'com.android.model.application' 

model { 
    android { 
     compileSdkVersion = 23 
     buildToolsVersion = "23.0.3" 

     defaultConfig.with { 
      applicationId = "com.nomad5.ndkdebug" 
      minSdkVersion.apiLevel = 16 
      targetSdkVersion.apiLevel = 23 
      versionCode = 1 
      versionName = "0.1" 
     } 
    } 
    /* 
    * native build settings 
    */ 
    android.ndk { 
     moduleName = "ndkDebugModule" 
     cppFlags.add("-I./../../../../../artoolkit5/include/ ") 
    } 

    android.buildTypes { 
     release { 
      minifyEnabled = false 
      proguardFiles.add(file('proguard-rules.txt')) 
     } 
     debug { 
      debuggable = true 
      ndk.with { 
       debuggable = true 
      } 
     } 
    } 
}

         arRoot.absolutePath + "/android/jni/curl/include"] 
     } 
     source { 
      /* we set this to NOT automatically compile everything */ 
      srcDirs = ["src/main"] 
      include "jni/nativeCodeA.cpp" 
      include "jni/nativeCodeB.cpp" 

     }

      srcDirs = [arRoot.absolutePath + "/include", 
         arRoot.absolutePath + "/android/jni/curl/include"] 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile project(':aRBaseLib') 
    compile 'com.android.support:appcompat-v7:23.4.0' 
}   

Проблема с Gradle НКА билда, что в моих файлах (nativeCodeA.cpp, например) все включает, которые в ../../../../../artoolkit5/android не найден. Поэтому все

#include <AR/ar.h> 
#include <AR/arMulti.h> 
#include <AR/video.h> 
... 

не найдены.

Как добавить папку в конструкцию ndk, известную как gradle, как LOCAL_C_INCLUDES в make-файле. И как я могу указать конкретные файлы для компиляции, как LOCAL_SRC_FILES в make-файле. (Как Gradle знает файлы, даже если не указать те явно?)

Кстати я использую

distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip 

с

'com.android.tools.build:gradle-experimental:0.4.0'

Хорошо, я исследовал много и нашли несколько примеров, которые работают. Прежде всего, вы должны использовать последнюю Gradle плагин как Экспериментальные это в корне build.gradle

'com.android.tools.build:gradle-experimental:0.4.0' 

Тогда ваш Gradle файл будет выглядеть следующим образом

apply plugin: 'com.android.model.application'
