20190722海外小米和国内华为的关联唤醒调研

本文主要是介绍20190722海外小米和国内华为的关联唤醒调研，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

关联/链式启动的拦截机制

Android P机型	进程拦截	组件拦截	预设置自启动名单
海外版-小米MI 8 Pro	有	有	有
国内版-华为P20 Pro	有	有	有

进程拦截：主要在冷启动限制开机启动、后台启动，功能界面一般为自启动管理、后台管理；

原理：ActivityManagerService. startProcessLocked() 条件拦截，即冷启动入口拦截

组件拦截：主要在冷/热启动限制开机启动、后台启动、应用间的唤醒，组件级别拦截，功能界面一般无界面显示、或关联启动界面、或启动记录、拦截记录；

原理：

ActivityManagerService. getContentProviderImpl() 条件拦截

ActiveServices. startServiceLocked() 条件拦截

ActiveServices. bindServiceLocked() 条件拦截

ActivityStarter. startActivity() 条件拦截

BroadcastQueue. processNextBroadcastLocked()条件拦截

区别：

两者的效果都是可以限制开机启动和后台启动，组件拦截比进程拦截的区别如下：

组件拦截的时机更早，因为应用启动是先启动组件，再最后fork进程；
组件拦截管控的范围更全，热启动类型的行为也可以有效拦截；
组件拦截精细度更高，例如进程拦截只知道进程被启动了，而组件拦截可以具体到哪个进程通过什么方式启动了目标进程；
主流的华为、OPPO、VIVO、小米都有组件拦截相关的机制；

综合上述：

海外版小米 MI 8 Pro 在自启动、后台管理、关联启动都有预置黑名单进行应用管理，故Android P 上我们也可以同海外版小米的配置预置自启动黑名单；

SmartManager完成了进程拦截，组件拦截可以在目前的冷启动场景的基础做查缺补漏的拦截优化，甚至做到个别场景不依赖配置名单，智能识别和拦截关联启动行为；

热启动场景进行组件级拦截，例如加强Google 原生的规则中后台第三方应用启动后台第三方进程的限制；

拦截记录的UI界面交互，需要产品工程师进行定义；

海外版-小米 MI 8 Pro

1.1 小米自启动

1. 小米关联/链式

小米的没有单独的关联唤醒拦截界面，但是“禁止耗电应用相互调用”属于关联唤醒范畴

2. 国内版-华为P20 Pro

1. 华为自启动

07-19 14:41:49.771 1000 1681 1705 D Boost : hostingType=broadcast, hostingName=com.android.cellbroadcastreceiver/.CellBroadcastReceiver, callerPackage=android, isSystem=true, isBoostNeeded=false.

07-19 14:41:52.599 1000 1681 2093 D Boost : hostingType=service, hostingName=com.miui.analytics/.AnalyticsService, callerPackage=com.miui.msa.global, isSystem=true, isBoostNeeded=false.

07-19 14:41:48.717 1000 1681 2072 D Boost : hostingType=content provider, hostingName=com.android.settings/.cloud.CloudSettingsProvider, callerPackage=com.android.systemui, isSystem=true, isBoostNeeded=false.

2.2 华为关联/链式

只有组件拦截才可以形成下述拦截记录

3. ROM-SMGR测评

条件	测试结果
1. 安装后，不进行任何操作，桌面待机	1 小时内，23个应用后台启动
2. 安装后，按smgr推荐名单设置，66个自启动黑名单，13个白名单，桌面待机	测试12小时，黑名单应用都被限制自启动，管控Pass

上述中分析：

不点开任何应用会有应用被启动的原因第一个被启动的应用，com.ss.android.article.news(uid:10129) 被 com.android.bluetooth(uid:1002) 通过 bind-service 关联启动. 存在第一个第三方应用被启动后，com.ss.android.article.news(uid:10129)通过 PUSH SDK相关的start-activity\start-service\bind-service\send-broadcast\content provider机制启动了更多的应用，手机出现后台进程数量多、卡顿、发热现象
SmartManager 的自启动管控早期版本的SmartManager存在漏洞，即content provider\activity 类型启动会不区分黑白名单直接允许后台运行。本次版本优化，主要策略如下：

1.启动类型service\broadcast\content provider的为非前台进程应用，后台启动会根据黑名单进行拦截
2.启动类型为 activity 类型的非前台进程，新增了一条过滤，即ClassName为 com.igexin.sdk.GActivity直接拦截启动，除此之外唐敏提供了更多Activity类型的透明界面异常后台启动：com.igexin.sdk.GActivity
com.tencent.pangu.link.LinkProxyActivity
com.ifeng.news2.getui.DynamicGetuiActivity
com.pingan.servicewindow.service.GeTuiActivity
3.灭屏30分钟内，查杀3次，亮屏每5分钟查杀后台进程

private static final List<String> ANNOYING_NAMES = new ArrayList<String>(){{

add("com.igexin.sdk.GActivity");

}
