Android Device Monitor 已在 Android Studio 3.1 中废弃，并已从 Android Studio 3.2 中移除。您可以通过 Android Device Monitor 使用的功能已被新功能所取代。下表可帮助您确定应使用哪些功能代替这些已废弃和已移除的功能。
启动 Android Device Monitor
如需在 Android Studio 3.1 及更低版本中启动独立的 Device Monitor 应用，请在命令行的 android-sdk/tools/ 目录中输入以下内容：
monitor
然后，您可以从 Devices 窗格中选择连接的设备，以将此工具关联到该设备。如果您无法查看相关窗格或窗口，请从菜单栏中依次选择 Window > Reset Perspective。
注意：每个设备一次只能附加到一个调试程序进程。因此，例如，如果您使用 Android Studio 在设备上调试应用，需要先断开 Android Studio 调试程序与该设备的连接，然后才能从 Android Device Monitor 附加调试程序进程。

The features that you could use\nthrough the Android Device Monitor have been replaced by new features. The table\nbelow helps you decide which features you should use instead of these deprecated\nand removed features.\n\n| Android Device Monitor component | What you should use |\n|----------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| **Dalvik Debug Monitor Server (DDMS)** | This tool is deprecated. Instead, use [**Android Profiler**](/studio/profile) in Android Studio 3.0 and higher to profile your app's CPU, memory, and network usage. If you want to perform other debugging tasks, such as sending commands to a connected device to set up port-forwarding, transfer files, or take screenshots, then use the [**Android Debug Bridge (`adb`)**](/studio/command-line/adb), [**Android Emulator**](/studio/run/emulator), [**Device Explorer**](/studio/debug/device-file-explorer), or [**Debugger window**](/studio/debug). |\n| **Traceview** | This tool is deprecated. To inspect `.trace` files captured by [instrumenting your app](/studio/profile/generate-trace-logs) with the [Debug](/reference/android/os/Debug) class, record new method traces, export `.trace` files, and inspect real-time CPU usage of your app's processes, use the Android Studio [**CPU profiler**](/studio/profile/cpu-profiler). |\n| **Systrace** | If you need to inspect native system processes and address UI jank caused by dropped frames, use [**`systrace `**](/topic/performance/tracing/command-line) from the command line or the simplified **System Trace** in the [**CPU Profiler**](/studio/profile/cpu-profiler). The **CPU Profiler** provides many features for profiling your app's processes. |\n| **Tracer for OpenGL ES** | Use the **[Android GPU Inspector](/agi)**. |\n| **Hierarchy Viewer** | If you want to inspect your app's view hierarchy at runtime, use [**Layout Inspector**](/studio/debug/layout-inspector). If you want to profile the rendering speed of your app's layout, use **[Window.OnFrameMetricsAvailableListener](/reference/android/view/Window.OnFrameMetricsAvailableListener)** as described in [this blog post](https://android-developers.googleblog.com/2017/08/understanding-performance-benefits-of.html). |\n| **Pixel Perfect** | Use **[Layout Inspector](/studio/debug/layout-inspector)**. |\n| **Network Traffic tool** | If you need to view how and when your app transfers data over a network, use the [**Network Profiler**](/studio/profile/network-profiler). |\n\nStart Android Device Monitor\n----------------------------\n\nTo start the standalone Device Monitor application in Android Studio 3.1 and\nlower, enter the following on the command line in the\n\u003cvar translate=\"no\"\u003eandroid-sdk\u003c/var\u003e`/tools/` directory: \n\n```\nmonitor\n```\n\n\u003cbr /\u003e\n\nYou can then link the tool to a connected device by selecting the device\nfrom the **Devices** pane. If you have trouble viewing panes or windows,\nselect **Window \\\u003e Reset Perspective** from the menu bar.\n\n**Note:** Each device can be attached to only one debugger\nprocess at a time. So, for example, if you are using Android Studio to debug\nyour app on a device, you need to disconnect the Android Studio debugger from\nthe device before you attach a debugger process from the Android Device\nMonitor."]]
