【亲测有效】在Android studio中导入.so文件

1、先在工程的libs文件下导入.so文件

2、在build.gradle中（本工程的gradle文件）中的android{}段内填入

/** 导入so文件 */task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") {    destinationDir file("$projectDir/libs")    baseName "Native_Libs2"    extension "jar"    from fileTree(dir: "libs", include: "**/*.so")    into "lib"}

tasks.withType(JavaCompile) {    compileTask -> compileTask.dependsOn(nativeLibsToJar)}

　在　

dependencies {}内加入

provided fileTree(dir: ‘libs‘, include: [‘*.jar‘])

3、将生成的Native_Libs.jar文件右键AddAsLibrary

-------------------------完成的gradle-------------------------------------------

apply plugin: ‘com.android.application‘

android {    compileSdkVersion 23    buildToolsVersion "23.0.0"

    defaultConfig {        applicationId "com.ntu.dc.smarthospital"        minSdkVersion 14        targetSdkVersion 23        versionCode 1        versionName "1.0"    }

    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘        }    }

    /** 导入so文件 */    task nativeLibsToJar(type: Zip, description: "create a jar archive of the native libs") {        destinationDir file("$projectDir/libs")        baseName "Native_Libs2"        extension "jar"        from fileTree(dir: "libs", include: "**/*.so")        into "lib"    }

    tasks.withType(JavaCompile) {        compileTask -> compileTask.dependsOn(nativeLibsToJar)    }}

dependencies {    provided fileTree(dir: ‘libs‘, include: [‘*.jar‘])    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])    compile ‘com.android.support:appcompat-v7:23.0.0‘    compile files(‘libs/nineoldandroids-library-2.4.0.jar‘)    compile project(‘:refresh‘)    compile files(‘libs/Msc.jar‘)    compile files(‘libs/Sunflower.jar‘)    compile files(‘libs/Native_Libs2.jar‘)}
