NDK使用
- JDK:Java Development Kit
- SDK:Software Development Kit
- NDK:Native Development Kit
- JNI: Java Nattive Interface
NDK开发流程：
- 下载NDK并配置NDK路径
- 新建项目
修改build.gradle文件
替换classpath:com.android.tools.build:gradle-experimental:0.4.0
替换apply plugin:com.android.model.application
添加moudel{}至android{},即:model{android{}}minSdkverion 15 targetSdkVersion 23
versionCode 1versionName "1.o"替换为minSdkVersion.apiLevel=4targetSdkVersion.apilevel=23- 添加android.ndk{moduleName="onlystar-android-jni-demo"}
- 参考实例Demo的build.gradle
apply plugin: 'com.android.model.application'model {android {compileSdkVersion = 23buildToolsVersion = "23.0.2"defaultConfig.with {applicationId = "com.example.hellojni"minSdkVersion.apiLevel = 15targetSdkVersion.apiLevel = 23}}compileOptions.with {sourceCompatibility=JavaVersion.VERSION_1_7targetCompatibility=JavaVersion.VERSION_1_7}/** native build settings*/android.ndk {moduleName = "geekband-hello-jni-demo"/** Other ndk flags configurable here are* cppFlags.add("-fno-rtti")* cppFlags.add("-fno-exceptions")* ldLibs.addAll(["android", "log"])* stl = "system"*/}android.buildTypes {release {minifyEnabled = falseproguardFiles.add(file('proguard-rules.txt'))}}android.productFlavors { // for detailed abiFilter descriptions, refer to "Supported ABIs" @ // https://developer.android.com/ndk/guides/abis.html#sacreate("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 emptycreate("all")}}dependencies {compile fileTree(dir: 'libs', include: ['*.jar'])testCompile 'junit:junit:4.12'compile 'com.android.support:appcompat-v7:23.1.1'compile 'com.android.support:design:23.1.1'}项目依赖
引入aar文件----两种方法
1.在build.gradle中添加
allprogects{responsitores{jcenter()flatDir{dirs 'libs'}}
}在dependencies中添加
compile(name:'aar_filename',ext:'aar')
2.新建module，选择 Import .JAR/.AAR Package，导入aar文件
