Question

根据链接http://ph0b.com/new-android-studio-ndk-support/查看子标题＆＃34;使用Android.mk/Application.mk" ;,文章声称可以使用Android Studio进行编辑和调试。我已按照该文章的所有说明进行操作，但调试器似乎从未遇到过断点。这对任何人都有效吗？

我的设置

Android Studio 1.4
Gradle 2.6
Android Gradle插件0.3.0-alpha5

我的build.gradle看起来像这样

申请插件：＆＃39; com.android.model.application＆＃39;

模型{ android { compileSdkVersion = 21 buildToolsVersion =＆＃34; 23.0.0 rc2＆＃34;

    defaultConfig.with {
        applicationId = "blah.blah1.com.blah3"
        minSdkVersion.apiLevel = 21
        targetSdkVersion.apiLevel = 22
        versionCode = 1
        versionName = "1.0"
    }
}

android.buildTypes {
    release {
        minifyEnabled = false
    }
}

android.ndk {
    moduleName = "blahPlayer"
    ldLibs = ["log"]
    cppFlags += "-std=c++11"
    cppFlags += "-I${blahRoot}".toString()
    stl = "gnustl_shared"
}

android.sources {
    main.jni {
        source {
            srcDirs = ['src/main/none']
        }
    }
    main.jniLibs {
        source {
            srcDirs = ['src/main/libs']
        }
    }
}

android.productFlavors {
    create("arm") {
        ndk.with {
            abiFilters += "armeabi-v7a"
        }
    }
}

}

我的原生资源在app / src / jni中的资源和FS的不同位置之间分配（因为某些来源是第三方）
代码完成正常（我可以在第三方源中包含和使用源代码）
我使用Android.mk和Application.mk以及外部的ndk-build构建所有本机源。 SO文件在jniLibs下生成，应用程序运行正常

当我在app / src / jni或第三方源位置的本机源中设置断点时，调试器永远不会命中它们。

使用传统的makefile编译时，生成如下结构：

-obj 
  -local
    -armeabi-v7a
        -obj-debub
         xxx.o
         xxx.d
         zzz.o
         zzz.d 
      hello-jni.so

使用Android Studio调试的技巧是jniLibs块的配置。必须是这样的：

main.jniLibs {
            source {
//                srcDirs = ['src/main/libs']
                srcDirs = ['src/main/obj/local']
            }
        }

为了不再怀疑，我的gradle看起来像这样。

    import org.apache.tools.ant.taskdefs.condition.Os
    plugin: 'com.android.model.application'
    model {
       android {
        compileSdkVersion = 23
        buildToolsVersion = "23.0.0"
        defaultConfig.with {
            applicationId = "com.example.hellojni"
            minSdkVersion.apiLevel = 4
            targetSdkVersion.apiLevel = 23
        }
        tasks.withType(JavaCompile) {
            compileTask -> compileTask.dependsOn buildNative
        }
      }

    compileOptions.with {
        sourceCompatibility=JavaVersion.VERSION_1_7
        targetCompatibility=JavaVersion.VERSION_1_7
     }
    android.ndk {
        moduleName = "hello-jni"
        stl = 'gnustl_shared'
     }
    android.sources {
        main.jni {
            source {// srcDirs = ['src/main/jni/']
                       srcDirs = ['src/main/jni/none']
            }
        }
        main.jniLibs {
            source {// srcDirs = ['src/main/libs']
                       srcDirs = ['src/main/obj/local']
            }
        }
     }
    android.buildTypes {
      release {
            minifyEnabled = false
            proguardFiles  += file('proguard-rules.txt')
        }
    }
   } 
   String getNdkDir() {
    if (System.env.ANDROID_NDK_ROOT != null)
        return System.env.ANDROID_NDK_ROOT
    Properties properties = new Properties()
    properties.load(project.rootProject.file('local.properties').newDataI
 putStream())
    String ndkdir = properties.getProperty('ndk.dir', null)
    if (ndkdir == null)
        throw new GradleException("NDK location not found. Define 
ocation with ndk.dir in the local.properties file or with an 
NDROID_NDK_ROOT environment variable.")
    return ndkdir
}
String getNdkBuildCmd() {
    String ndkbuild = getNdkDir() + "/ndk-build"
    if (Os.isFamily(Os.FAMILY_WINDOWS))
      ndkbuild += ".cmd"
    return ndkbuild
}
task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
    commandLine getNdkBuildCmd(),
            '-C', file('src/main/').absolutePath, // Change src/main/jni the relative path to your jni source
            '-j', Runtime.runtime.availableProcessors()
//            'NDK_DEBUG=1'
}

我的Android.mk文件：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include $(LOCAL_PATH)/Application.mk
LOCAL_MODULE := hello-jni
LOCAL_PATH := $(call my-dir)
LOCAL_C_INCLUDES := $(LOCAL_PATH)/
LOCAL_LDLIBS := -llog \
                 -landroid \
LOCAL_SRC_FILES := bmain.c \
                   hello-jni.c
LOCAL_CPPFLAGS += -std=c++11
include $(BUILD_SHARED_LIBRARY)

我的Application.mk文件：

APP_OPTIM := debug
APP_ABI   := armeabi-v7a
APP_PLATFORM := android-10
APP_STL := gnustl_static

使用Traditional make文件调试AndroidStudio NDK
