我想把Android Studio作为我的主要开发IDE用于Java和C/C++代码。我希望能够调试本地代码。
在这种情况下,我正在尝试使用ARToolkit5作为库。
由于ARToolkit5中的一些示例,我有这个构建文件。

这个构建正在正常工作。现在我正在尝试将其转换为Android实验性Gradle文件以便能够进行调试。目前我处于这个状态:
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
}
}
}
}

android.sources.main {
jni {
exportedHeaders {

arRoot.absolutePath + "/android/jni/curl/include"]

Gradle ndk构建的问题在于,我的文件(例如
nativeCodeA.cpp
)中所有在../../../../../artoolkit5/android
中的包含都无法找到。因此,所有的...#include <AR/ar.h>
#include <AR/arMulti.h>
#include <AR/video.h>
...
找不到。
如何像makefile中的LOCAL_C_INCLUDES
一样将文件夹添加到gradle感知的ndk构建中。并且如何像makefile中的LOCAL_SRC_FILES
一样指定要编译的特定文件。(即使没有显式指定,Gradle如何知道这些文件?)
顺便说一下,我正在使用
distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip
使用
'com.android.tools.build:gradle-experimental:0.4.0'
