【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')
}
