问题
在Android 7的机器上下载ktcp应用后，即使把ktcp的receiver组件全部disable掉，重启开机还是会启动ktcp
根据日志和dumpsys package com.ktcp.video发现CHRestoreBroadcastReceiver已经disable了，但是还是因为接收开机广播被拉起来
logcat日志ActivityManager: Start proc 4216:com.ktcp.video/u0a59 for broadcast com.ktcp.video/.receiver.CHRestoreBroadcastReceiverdumpsys信息disabledComponents: ……com.ktcp.video.receiver.CHRestoreBroadcastReceiver
分析
思路1：完整了解Android是如何通过disable component禁止应用启动的
接收开机广播启动进程的日志如下，在processNextBroadcast()通过startProcessLocked()启动的
BroadcastQueue: Need to start app [background] ****** for broadcast BroadcastRecord{82a3f50 u0 android.intent.action.BOOT_COMPLETED}
ActivityManager: startProcess: name=****** app=null knownToBeDead=true thread=null pid=-1
ActivityManager: startProcessLocked
ActivityManager: java.lang.Exception
ActivityManager: at com.android.server.am.ActivityManagerService.startProcessLocked(ActivityManagerService.java:3691)

ActivityManager: at android.os.Binder.execTransact(Binder.java:565)在这个地方将所有BOOT_COMPLETED的接收者打印出来发现receivers中有CHRestoreBroadcastReceiver
这个地方由于广播接收者太多一共64个，直接打印的话日志打不全，需要循环打印
1375 2411 V BroadcastQueue: recIdx=62, receivers.size()=641375 1799 V BroadcastQueue: recIdx=63, receivers.size()=64
那Android时怎么把disableComponet的receiver添加到receivers中的呢？
这里就涉及到Intent、IntentFilter、IntentResolve相关的逻辑，找深入理解Android卷II看看整体逻辑，在加日志分析
发现是在开机阶段PackageManager扫描apk包时直接添加上了，这样整个流程就搞明白了
CHRestoreBroadcastReceiver明明状态时COMPONET_ENABLED_STATE_DISABLED，但是还是通过addFilter加到接收者队列中了
W PackageManager: ==> For Activity com.ktcp.video.receiver.CHRestoreBroadcastReceiver
W PackageManager: intent= ActivityIntentInfo{bc38401 com.ktcp.video/.receiver.CHRestoreBroadcastReceiver}
V PackageManager: type=receiver, a.getComponentName()=ComponentInfo{com.ktcp.video/com.ktcp.video.receiver.CHRestoreBroadcastReceiver}, 2

V IntentResolver: Category: "android.intent.category.Default"
V IntentResolver: AutoVerify=false
V IntentResolver: Building Lookup Maps:
V IntentResolver: Action: android.intent.action.BOOT_COMPLETED整个流程明白后，就可以有相应的解决方案了
注意事项：
（1）日志过长，logcat打不全
（2）试解决方法时，先加日志，日志符合预期后在真正添加，不然加的不对，系统经常挂掉
