Androidstudio正確導入so文件方式

方法一： 
將libs文件夾下的so文件，通過gradle配置任務編譯成jar文件。 

apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
    }


    /** 導入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'])
}

方法二： 
通過插件將so文件依賴到jniLibs文件夾。 

方法三： 
最佳方法。 

android {
    sourceSets.main.jniLibs.srcDirs = ['libs']

    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
    }

}
