Android插件化开发和组件化开发其实是类似的，都是为了便捷开发，提高效率。但插件化的一个好处就是可以实现在线下载更新安装插件，类似热更新的功能，而热更新的classloder技术在插件化中也是关键点。
主要插件化框架：
2019年 爱奇艺qisaw 腾讯shadow
2017年 滴滴virtualapk 360 Replugin
之前还有ali altas Driodplugin等等
主要的技术我觉得是类似的，shadow号称0HOOK，但aiqiyi说看了企鹅的源码，是有hook的，有兴趣可以看看
主要尝试了shadow和replugin，因为对比下来这两种用户广泛，而且兼容性好些
shadow我down了源码和demo，能够很好的运行，但对已有项目的更改可能稍多，同时调研了replugin，感觉replugin的集成更加快捷，先行记录
1.由于兼容或资源问题，宿主的工程添加
maven{url "https://dl.bintray.com/soli/maven"}2.添加RePlugin Host Gradle依赖
classpath 'com.qihoo360.replugin:replugin-host-gradle:2.3.1'3.宿主的app gradle
implementation 'com.qihoo360.replugin:replugin-host-lib:2.2.1' // 集成 RePlugin 添加的配置4.
一是继承RePluginApplication
public class App extends RePluginApplication二是非继承的方式
public class MainApplication extends Application { @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); RePlugin.App.attachBaseContext(this); .... } @Override public void onCreate() { super.onCreate(); RePlugin.App.onCreate(); .... } @Override public void onLowMemory() { super.onLowMemory(); /* Not need to be called if your application's minSdkVersion > = 14 */ RePlugin.App.onLowMemory(); .... } @Override public void onTrimMemory(int level) { super.onTrimMemory(level); /* Not need to be called if your application's minSdkVersion > = 14 */ RePlugin.App.onTrimMemory(level); .... } @Override public void onConfigurationChanged(Configuration config) { super.onConfigurationChanged(config); /* Not need to be called if your application's minSdkVersion > = 14 */ RePlugin.App.onConfigurationChanged(config); .... } }5.plugin app
buildscript { dependencies { classpath 'com.qihoo360.replugin:replugin-plugin-gradle:2.2.4' ... } } apply plugin: 'replugin-plugin-gradle' dependencies { compile 'com.qihoo360.replugin:replugin-plugin-lib:2.2.4' ... }6.plugin apk存放路径
只需两步即可：
将APK改名为：[插件名].jar放入主程序的assets/plugins目录好了，准备打开插件吧
Intent intent = RePlugin.createIntent("demo2", "com.qihoo360.replugin.sample.demo2.databinding.DataBindingActivity"); context.startActivity(intent);
到此replugin就集成完了，能正常启动app中的apk了，但是可能运行中遇到各种问题，
1.比如replugin不支持java8，因此你的插件项目如果使用了java8的新特性，如lambad表达式等，就需要进行改造了
2.项目必须包含v4或者v7包，否则会报错，replugin用到了包里的loadmanager
3.gradle版本问题，如果遇到莫名其妙的问题，考虑gradle版本和replugin版本的问题
还有很多设置，比如插件别名，多进程，外置插件等等，这些都简单些了，看需要研究，最主要的是能集成，跑起来。
我demo的源码：
