启动Activity
- 显式启动，常规启动使用：
am start packageName/ActivityName
隐式启动：
am start -a actionName pacakgeName
- 系统应用启动
am start -W com.oppo.camera
- 普通应用想通过包名启动，分两个阶段
//1.通过monkey命令查询b得到启动activity（关注 + Using main activity这一行即可！！！） monkey -v -v -v -p com.example.component -c android.intent.category.LAUNCHER 0 bash arg: -v bash arg: -v bash arg: -v bash arg: -p bash arg: com.example.component bash arg: -c bash arg: android.intent.category.LAUNCHER bash arg: 0 args: [-v, -v, -v, -p, com.example.component, -c, android.intent.category.LAUNCHER, 0] arg: "-v" arg: "-v" arg: "-v" arg: "-p" arg: "com.example.component" arg: "-c" arg: "android.intent.category.LAUNCHER" arg: "0" data="com.example.component" data="android.intent.category.LAUNCHER" .ConversationList (from package com.android.mms) // - NOT USING main activity com.coloros.weather.main.view.WeatherMainActivity (from package com.coloros.weather2) // - NOT USING main activity com.dianping.v1.NovaMainActivity (from package com.dianping.v1) // - NOT USING main activity com.duowan.kiwi.simpleactivity.SplashActivity (from package com.duowan.kiwi) // - NOT USING main activity com.eg.android.AlipayGphone.AlipayLogin (from package com.eg.android.AlipayGphone) // + Using main activity com.example.component.MainActivity (from package com.example.component) // - NOT USING main activity com.mc10086.cmcc.base.StartPageActivity (from package com.greenpoint.android.mc10086.activity) // - NOT USING main activity com.heytap.health.oobe.LaunchActivity (from package com.heytap.health) ## Network stats: elapsed time=49ms (0ms mobile, 0ms wifi, 49ms not connected) // Monkey finished //2.获取activity再结合包名启动（参考前面）启动Service
am startservice am stopservice发送广播
给未启动应用发送广播，用于启动
//参考intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES) am broadcast -a com.example.component.StartAction -f 32 com.example.component //必须以静态广播方式注册启动instrument测试（自动化测试很多使用这里的原理）
am instrument 测试apk包名/测试apk中的Instrumentaion实现类，原生是AndroidJUnitRunner
