试图将.so文件添加到我的android studio应用程序中

Question

我试图将.so文件添加到我的应用程序中并且我得到以下错误：

E/AndroidRuntime: FATAL EXCEPTION: main

我试图添加

compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')

和

task nativeLibsToJar(type: Jar, description: 'create a jar archive of the native libs') {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}

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

这些文件位于名为jniLibs的目录下 - ＆gt; armeabi-V7A / 86
