步骤：

1. build.gradle 配置如下，主要两项 ndk 和 sourceSets

apply plugin: ‘com.android.application‘

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.1"
    defaultConfig {
        applicationId "com.shuguo.myapplication"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        ndk {
            moduleName "native-lib"
            ldLibs "log", "z", "m"
            abiFilters "armeabi", "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(‘proguard-android-optimize.txt‘), ‘proguard-rules.pro‘
        }
    }
    sourceSets {
        main {
            jniLibs.srcDirs = [‘src/main/jni/libs‘]
        }
    }
}
2. 创建jni目录，file->new->folder->jnifolder
3. 配置ndk-build 
4. 创建.h文件，cpp文件
5. 编写Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE := native-lib
LOCAL_C_INCLUDES := com_shuguo_myapplication_JniClass.h
LOCAL_SRC_FILES := com_shuguo_myapplication_JniClass.cpp

LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)
6. 编写Application.mk

APP_ABI := armeabi armeabi-v7a x86
7. 在cmd中使用如下命令

　　C:\Users\baoyi.yang\Desktop\MyApplication\app\src\main\jni>ndk-build NDK_PROJECT
　　_PATH=. APP_BUILD_SCRIPT=./Android.mk NDK_APPLICATION_MK=./Application.mk

　8. 编译
