Android Device Monitor は、Android Studio 3.1 でサポートが終了し、Android Studio 3.2 からは削除されています。Android Device Monitor で使用できる機能は、新機能に置き換えられました。以下の表に基づいて、サポートが終了した機能や削除された機能の代わりに使用できる機能をご確認ください。
Android Device Monitor を起動する
Android Studio 3.1 以降でスタンドアロンの Device Monitor アプリケーションを起動するには、android-sdk/tools/ ディレクトリで、コマンドラインに次のように入力します。
monitor
[Devices] ペインでデバイスを選択すると、ツールと接続デバイスをリンクできます。ペインやウィンドウの表示に問題がある場合は、メニューバーから [Window] > [Reset Perspective] を選択してください。
注: 各デバイスにアタッチできるデバッガ プロセスは、一度に 1 つだけに限られます。そのため、たとえば、Android Studio を使用してデバイス上のアプリをデバッグしている場合、Android Device Monitor からデバッガ プロセスをアタッチするには、Android Studio デバッガをデバイスから切断する必要があります。

The features that you could use\nthrough the Android Device Monitor have been replaced by new features.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."]]
