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 =
buildToolsVersion = "23.0.2"
defaultConfig.with {
applicationId = "me.chunsheng.jni"
minSdkVersion.apiLevel =
targetSdkVersion.apiLevel =
}
}
/*
* 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
