简介
dumpsys是一种在Android设备上运行的工具，它提供有关系统服务的信息。 您可以使用Android(ADB）从命令行调用dumpsys，以获取在连接设备上运行的所有系统服务的诊断输出。 此输出通常比您想要的更冗长，因此请使用下面描述的命令行选项仅为您感兴趣的系统服务获取输出。此页面还介绍了如何使用dumpsys完成常见任务，例如检查输入 ，RAM，电池或网络诊断.

adb shell dumpsys activity top
adb shell dumpsys activity top
输出
TASK android.task.contacts id=42 userId=0
ACTIVITY com.android.contacts/.activities.PeopleActivity 6cf28a9 pid=19638
Local Activity e579e8d State:
mResumed=true mStopped=false mFinished=false
// ... 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，根据输出可得到联系人的应用包名是：「com.android.contacts」
adb shell dumpsys activity activities
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 」
