这个bash窗口怎么打开的，如何登陆成功的呢，这部分老师在后续课程中能演示么

C:\Users\Administrator>adb shell am start -n com.tencent.mobileqq/.activity.QQLSActivity -S Stopping: com.tencent.mobileqq Starting: Intent { cmp=com.tencent.mobileqq/.activity.QQLSActivity } Security exception: Permission Denial: starting Intent { flg=0x10000000 cmp=com.tencent.mobileqq/.activity.QQLSActivity } from null (pid=22030, uid=2000) not exported from uid 10128 java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.tencent.mobileqq/.activity.QQLSActivity } from null (pid=22030, uid=2000) not exported from uid 10128 at com.android.server.am.ActivityStackSupervisor.checkStartAnyActivityPermission(ActivityStackSupervisor.java:1953) at com.android.server.am.ActivityStarter.startActivity(ActivityStarter.java:1264) at com.android.server.am.ActivityStarter.startActivity(ActivityStarter.java:685) at com.android.server.am.ActivityStarter.startActivityMayWait(ActivityStarter.java:2310) at com.android.server.am.ActivityStarter.execute(ActivityStarter.java:625) at com.android.server.am.ActivityManagerService.startActivityAsUser(ActivityManagerService.java:6109) at com.android.server.am.ActivityManagerService.startActivityAsUser(ActivityManagerService.java:6078) at com.android.server.am.ActivityManagerShellCommand.runStartActivity(ActivityManagerShellCommand.java:479) at com.android.server.am.ActivityManagerShellCommand.onCommand(ActivityManagerShellCommand.java:161) at android.os.ShellCommand.exec(ShellCommand.java:103) at com.android.server.am.ActivityManagerService.onShellCommand(ActivityManagerService.java:19106) at android.os.Binder.shellCommand(Binder.java:634) at android.os.Binder.onTransact(Binder.java:532) at android.app.IActivityManager$Stub.onTransact(IActivityManager.java:3500) at com.android.server.am.ActivityManagerService.onTransact(ActivityManagerService.java:3860) at com.android.server.am.OppoActivityManagerService.onTransact(OppoActivityManagerService.java:853) at android.os.Binder.execTransact(Binder.java:731)

老师，请问有推荐的IOS模拟器么？

我用真机启动直接就杀死了，不能启动

我用真机 （输入命令打开app进不去）

win10的电脑，输入adb logcat | grep -i displayed查找包名，却报错显示：'grep' 不是内部或外部命令，也不是可运行的程序 或批处理文件。

老师，我使用你说的adb logcat | grep Displayed命令，在gitbash里边获取程序的入口，雪球已经启动起来，然后捕获到了一个 Displayed com.xueqiu.android/.view.WelcomeActivityAlias， Displayed com.xueqiu.android/.common.MainActivity，我在百度上没有查出来他们两个的区别。如果有其他app的话，选择包名和启动名的话，就选择welcomeActivity吗 $ adb logcat | grep Displayed I/ActivityManager( 1761): Displayed com.vphone.launcher/.Launcher: +5s645ms I/ActivityManager( 1761): Displayed com.android.settings/.Settings: +1s970ms I/ActivityManager( 1761): Displayed com.xueqiu.android/.view.WelcomeActivityAlias: +6s448ms I/ActivityManager( 1761): Displayed com.xueqiu.android/.common.MainActivity: +5s28ms

老师我启动luckin coffee 的时候报以下错，为什么呢 $ adb shell am start -n com.lucky.luckyclient/.splash.boot.BootAdvertActivity -S Stopping: com.lucky.luckyclient Starting: Intent { cmp=com.lucky.luckyclient/.splash.boot.BootAdvertActivity } Security exception: Permission Denial: starting Intent { flg=0x10000000 cmp=com.lucky.luckyclient/.splash.boot.BootAdvertActivity } from null (pid=16267, uid=2000) not exported from uid 10189 java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.lucky.luckyclient/.splash.boot.BootAdvertActivity } from null (pid=16267, uid=2000) not exported from uid 10189 at com.android.server.am.ActivityStackSupervisor.checkStartAnyActivityPermission(ActivityStackSupervisor.java:1702) at com.android.server.am.ActivityStarter.startActivity(ActivityStarter.java:467) at com.android.server.am.ActivityStarter.startActivityLocked(ActivityStarter.java:283) at com.android.server.am.ActivityStarter.startActivityMayWait(ActivityStarter.java:913) at com.android.server.am.ActivityManagerService.startActivityAsUser(ActivityManagerService.java:4734) at com.android.server.am.ActivityManagerShellCommand.runStartActivity(ActivityManagerShellCommand.java:417) at com.android.server.am.ActivityManagerShellCommand.onCommand(ActivityManagerShellCommand.java:141) at android.os.ShellCommand.exec(ShellCommand.java:96) at com.android.server.am.ActivityManagerService.onShellCommand(ActivityManagerService.java:15518) at android.os.Binder.shellCommand(Binder.java:597) at android.os.Binder.onTransact(Binder.java:495) at android.app.IActivityManager$Stub.onTransact(IActivityManager.java:4328) at com.android.server.am.ActivityManagerService.onTransact(ActivityManagerService.java:3020) at android.os.Binder.execTransact(Binder.java:702)

怎么不讲Windows电脑上的查看打印log文件查看APP启动入口的命令？

老师您好！ 使用真机执行命令 adb shell am start -W -n com.xxx.xxx/.mvp.ui.activity.MainActivity -S 运行我们公司app的时候报错 报错信息： Stopping: com.xxx.xxx Starting: Intent { cmp=com.xxx.xxx/.mvp.ui.activity.MainActivity } Security exception: Permission Denial: starting Intent { flg=0x10000000 cmp=com.xxx.xxx/.mvp.ui.activity.MainActivity } from null (pid=4558, uid=2000) not exported from uid 10275
