Android studio 项目支持JNI方法

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->jnifolder3. 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-libLOCAL_C_INCLUDES := com_shuguo_myapplication_JniClass.hLOCAL_SRC_FILES := com_shuguo_myapplication_JniClass.cpp

LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)6. 编写Application.mk

APP_ABI := armeabi armeabi-v7a x867. 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
