出发点一：
Android 引入了「任务栈」的概念，这个概念对于 Android 设备上的返回按键有极其重要的联系。有时候按下返回按钮或者点击关闭当前 Activity 的操作，都不知道 Android 系统会把程序带到哪个 Activity ，不确定这是否是最后一个 Activity 以致退出了整个程序。亦或者一些按钮和操作循环产生 Activity 而造成内存膨胀。对于这些问题，如果能够在调试期间知道当前任务栈的情况，就能很方便的观察和发现问题存在的原因，进而选择正确的 launchMode ，设置且当 Intent 的 Flag 来使程序达到预期的效果。 出发点二：手机里装着一个应用，在不反编译也不做其他处理的情况下，你可以对这个应用了解多少。 出发点三：「出自官方文档」dumpsys is a tool that runs on Android devices and provides information about system services. You can call dumpsys from the command line using the Android Debug Bridge (ADB) to get diagnostic output for all system services running on a connected device. This output is typically more verbose than you may want, so use the command line options described below to get output for only the system services you're interested in. This page also describes how to use dumpsys to accomplish common tasks, such as inspecting input, RAM, battery, or network diagnostics. 命令格式： adb shell dumpsys activity [options] [WHAT] option 参数 options 含义 -a 包括所有可用 Servier 状态 -c 包括 Client 状态，即 App 端情况 -p PACKAGE 限定输出指定包名 WHAT 参数 WHAT 含义 a[ctivities] activity 状态 b[roadcasts] [PACKAGE_NAME] broadcast 状态 s[ervices] [COMP_SPEC ...] service 状态 prov[iders] [COMP_SPEC ...] content provider 状态 p[rocesses][PACKAGE_NAME] 进程状态 o[om] 内存管理 i[ntents] [PACKAGE_NAME] pending intent 状态 r[ecents] 最近 activity perm[issions] URI 授权情况 all 所有 activities 信息 top 顶部 activity 信息 package package 相关信息 开始练习 练习一：输入： adb shell dumpsys activity输出： ACTIVITY MANAGER PENDING INTENTS (dumpsys activity intents) //注意一下 * PendingIntentRecord{1004eb1 com.tencent.mobileqq broadcastIntent} * PendingIntentRecord{a9858c7 com.google.android.gms broadcastIntent} * PendingIntentRecord{dc3ae3d com.tencent.mm startService} // 省略 N 行 ... ACTIVITY MANAGER BROADCAST STATE (dumpsys activity broadcasts) //注意一下 Historical broadcasts [foreground]: #0: BroadcastRecord{63c6dd9 u-1 android.hardware.usb.action.USB_STATE} // 省略 N 行 ...

ACTIVITY MANAGER URI PERMISSIONS (dumpsys activity permissions) //注意一下 Granted Uri Permissions: * UID 10129 holds: UriPermission{b827fb4 0 @ content://downloads/all_downloads/125} UriPermission{2b167dd 0 @ content://downloads/all_downloads/134} UriPermission{51cbf52 0 @ content://downloads/all_downloads/148} UriPermission{af4a223 0 @ content://downloads/all_downloads/169} ACTIVITY MANAGER SERVICES (dumpsys activity services) //注意一下 User 0 active services: * ServiceRecord{da1e320 u0 com.android.bluetooth/.hid.HidService} app=null created=-12d3h35m44s197ms started=false connections=1 // 省略 N 行 ...

PendingIntentRecord adb shell dumpsys activity broadcasts adb shell dumpsys activity providers// Published single-user content providers (by class) / Published user 0 content providers (by class) / adb shell dumpsys activity permissions adb shell dumpsys activity services adb shell dumpsys activity recents adb shell dumpsys activity activities adb shell dumpsys activity processes 练习二：输入： adb shell dumpsys activity top输出： TASK com.jianshu.haruki id=101 ACTIVITY com.jianshu.haruki/com.baiji.jianshu.MainActivity fb571c1 pid=21291 // ... 只举出了前两行，省略了 N 行代码获取当前 Android 系统中与用户交互的 Activity 的详细信息，根据输出可得到简书的应用包名是：「com.jianshu .haruki」 练习三：输入： adb shell dumpsys activity activities意义： 显示当前所有在运行的任务栈，它们的 id 分别是什么。对于每个 Task 也有 Activity 数量等信息，同时也列出了其中的 Activity 列表，并且对于每个 Activity 也有比较详细的描述，比如启动它的 Intent 的内容。如果觉得内容过多，只想看看栈的内容，也可以直接跳到「Running activities (most recent first) 那部分，比较简洁而又明了的列出了栈中的 Activity 列表，就能知道当按下返回键的时候会应该回到哪个 Activity 」 练习四：输入： adb shell dumpsys package com.jianshu.haruki[此处写的是『简书』的应用包名]输出： Activity Resolver Table: // 标注：这里开始解析「activity」标签 Full MIME Types: text/plain: 28edf2a com.jianshu.haruki/com.baiji.jianshu.ui.editor.EditorActivityV19 Base MIME
