Android studio 配置JNI环境

Android studio配置jni开发环境，主要配置是两个build文件，以及新建一个jni文件，放c代码。

代码如下1：

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

model {
    android {
        compileSdkVersion = 23
        buildToolsVersion = "23.0.2"

        defaultConfig.with {
            applicationId = "me.chunsheng.jni"
            minSdkVersion.apiLevel = 9
            targetSdkVersion.apiLevel = 23
        }

    }


    /*
 * native build settings
 */
    android.ndk {
        moduleName = "hello-world"
        /*
    moduleName = "hello-jni"
     * Other ndk flags configurable here are
     * cppFlags.add("-fno-rtti")
     * cppFlags.add("-fno-exceptions")
     * ldLibs.addAll(["android", "log"])
     * stl       = "system"
     */
    }

    android.buildTypes {
        release {
            minifyEnabled = false
            multiDexEnabled = true
            proguardFiles.add(file("proguard-rules.pro"))
        }
    }


    android.productFlavors {
        // for detailed abiFilter descriptions, refer to "Supported ABIs" @
        // https://developer.android.com/ndk/guides/abis.html#sa
        create("arm") {
            ndk.abiFilters.add("armeabi")
        }
        create("arm7") {
            ndk.abiFilters.add("armeabi-v7a")
        }
        create("arm8") {
            ndk.abiFilters.add("arm64-v8a")
        }
        create("x86") {
            ndk.abiFilters.add("x86")
        }
        create("x86-64") {
            ndk.abiFilters.add("x86_64")
        }
        create("mips") {
            ndk.abiFilters.add("mips")
        }
        create("mips-64") {
            ndk.abiFilters.add("mips64")
        }
        // To include all cpu architectures, leaves abiFilters empty
        create("all")
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
}

代码如下2：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle-experimental:0.4.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

直接编译，运行即可调用c代码了，本次Android studio版本 2.0—beta 7.以及配置文件如上。

由于版本更新，gradle的语法的改变，build文件可能会发生变化，时刻关注官网
