GradleToSo

so shared object jni java native interface ndk native developmentit

Android Studio 生成so文件的两种方法

此demo是方式1

1.配置local.properties gradle.properties app下的build.gradle

ndk.dir=/Users/MaShiZhao/Android/sdk/ndk-bundle sdk.dir=/Users/MaShiZhao/Android/sdk

android.useDeprecatedNdk=true

defaultConfig { applicationId "com.example.mashizhao.gradleso" minSdkVersion 14 targetSdkVersion 25 versionCode 1 versionName "1.0"

    ndk {
        moduleName "GradleSo"          //生成的so名字
        abiFilters "armeabi", "armeabi-v7a", "x86" //输出指定三种abi体系结构下的so库，可忽略
    }
}

compile 'com.android.tools.build:gradle-experimental:0.7.0'

2.创建java

public class Jni { static { System.loadLibrary("GradleSo"); }

public static native String stringFromJNI();

}

//不知道这两部如何精简

stringFromJNI报错 command+enter

注释掉build.gradle里面的 compile 'com.android.tools.build:gradle-experimental:0.7.0'

仍然给报错在command+enter

3.在app/build/intermediates/ndk/debug/lib 下有so文件

完成
