通俗易懂接入阿里Sophix热修复

Sophix平台：https://emas.console.aliyun.com/
移动热修复（Mobile Hotfix）是面向移动互联网的APP热修复解决方案。产品基于阿里巴巴首创Hotpatch技术，提供细粒度热修复能力，无需等待，实时修复应用线上问题。
说明：Sophix平台创建应用，创建完根据提示下载aliyun-emas-services.json文件，需要用到三个参数：App ID、App Secret、RSA密钥。

接入SDK

编辑项目级build.gradle

buildscript {
    repositories {
        google()
        jcenter()
        //阿里
        maven { url "http://maven.aliyun.com/nexus/content/repositories/releases" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        //阿里
        // 添加emas-services插件
        classpath 'com.aliyun.ams:emas-services:1.0.1'

    }
}

allprojects {
    repositories {
        google()
        jcenter()
        //阿里
        maven { url "http://maven.aliyun.com/nexus/content/repositories/releases" }
        
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

---

编辑app级build.gradle

在 apply plugin: 'com.android.application'下面加入

apply plugin: 'com.android.application'

在dependencies里加入

 //阿里SopHix热修复
 implementation 'com.aliyun.ams:alicloud-android-hotfix:3.2.6'

编辑 AndroidManifest.xml

在application

在application里加入

把下载的aliyun-emas-services.json文件放到项目app目录下

如果运行报错

java.lang.RuntimeException: Manifest merger failed with multiple errors, see logs
解决方法
打开AndroidManifest.xml
点击下面的Merged Manifest
这时你会看到具体报错信息，修改掉即可

布局 activity_main

项目代码大功告成啦

最后下载补丁和调试工具

patch补丁包生成需要使用到打补丁工具SophixPatchTool, 如还未下载打包工具，请前往下载Android打包工具。
