在 Android 模拟器中运行 Sceneform 应用
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
使用 Android 模拟器在没有实体设备的情况下测试 AR 场景。借助 Android 模拟器，您可以在受您控制的模拟设备的虚拟环境中运行 ARCore 应用。
设置您的开发环境
软件要求：
硬件要求：
- 您还需要一个支持 OpenGL ES 3.0 或更高版本的开发机器才能在您的应用中使用 Sceneform。
安装 Android Studio 3.1 或更高版本。
在 Android Studio 中，依次转到 Preferences > Appearance and Behavior > System Settings > Android SDK。
选择 SDK Platforms 标签页，然后勾选 Show Package Details。
在 Android 8.1 (Oreo) 下，选择：
Google APIs Intel x86 Atom System Image API 级别 27，版本 4 或更高版本。
选择 SDK Tools 标签页，然后添加 Android 模拟器 27.2.9 或更高版本。
点击 OK 以安装选定的软件包和工具。
再次点击确定以确认更改。
接受组件安装程序的许可协议。
点击 Finish。
创建支持 AR 的虚拟设备
您可以按照 Android Studio 说明来创建支持 AR 的虚拟设备。
- 选择 Pixel 或 Pixel 2 硬件配置文件。
- 选择 Oreo：API 级别 27：x86：Android 8.1 (Google API) 系统映像。
确认您的虚拟设备已正确配置：
- 转到验证配置 > 显示高级设置。
- 确保相机返回设置为 VirtualScene。
Sceneform 需要 OpenGL ES 3.0 或更高版本。
确保您的模拟器已配置为使用最新版本的 OpenGL ES：
- 点击正在运行的模拟器工具栏中的
![了解详情]()
。
- 依次选择设置 > > 高级 >：OpenGL ES API 级别 > 渲染程序最大值（最高为 OpenGL ES 3.1）。
- 重启模拟器。出现提示时，请勿保存当前状态。
重启模拟器后，与模拟设备进行短暂的互动，然后通过 grep 命令查看设备日志，检查是否使用了 OpenGL ES 3.0 或更高版本：
adb logcat | grep eglMakeCurrent
如果您看到 ver 3 0 或更高版本，则可以在模拟器中运行 Sceneform 应用：
… … … … D EGL_emulation: eglMakeCurrent: 0xebe63540: ver 3 0 (tinfo 0xd104cb40)
如果您看到的是更低版本，则表示您的桌面设备 GPU 不支持 OpenGL ES 3.0，您必须改用一台受支持的设备来运行 Sceneform 应用。
运行您的应用
在模拟器中支持 AR 的虚拟设备上测试 ARCore 应用。为此，您可以按照 Android Studio 说明在 Android 模拟器中运行应用。
更新面向 AR 的 Google Play 服务
模拟器上适用于 AR 的 Google Play 服务版本可能已过时。请按照以下说明进行更新：
从 GitHub 版本页面下载最新的 Google_Play_Services_for_AR_1.15.0_x86_for_emulator.apk。
将下载的 APK 安装到您要使用的每个 AVD 中：
启动所需的 AVD，然后将下载的 APK 拖动到正在运行的模拟器上，或者在虚拟设备运行时使用 adb 进行安装：
adb install -r Google_Play_Services_for_AR_1.15.0_x86_for_emulator.apk
对您要使用的任何其他 AVD 重复上述步骤。
控制虚拟场景
当应用连接到 ARCore 时，您会在模拟器窗口下方看到描述如何控制摄像头的叠加层和状态栏。

To do\nthis, you can follow the [Android Studio instructions](//developer.android.com/studio/run/emulator.html#runningapp) to\nrun an app in the Android Emulator.\n| **Note:** To run apps with NDK components in the Android Emulator, your app must be built with [**x86 ABIs**](//developer.android.com/ndk/guides/abis.html). For an example, see the [**ARCore HelloAR C sample app**](//github.com/google-ar/arcore-android-sdk/tree/master/samples/hello_ar_c).\n\n### Update Google Play Services for AR\n\nThe version of Google Play Services for AR on the emulator is likely out of\ndate. Follow these instructions to update it:\n\n1. Download the latest **Google_Play_Services_for_AR_1.15.0_x86_for_emulator.apk** from the GitHub\n [releases](//github.com/google-ar/arcore-android-sdk/releases) page.\n\n2. Install the downloaded APK into each AVD you'd like to use:\n\n Start the desired AVD, then drag the downloaded APK onto the running\n emulator, or install it using `adb` while the virtual device is running: \n\n ```\n adb install -r Google_Play_Services_for_AR_1.15.0_x86_for_emulator.apk\n ```\n\n \u003cbr /\u003e\n\nRepeat these steps process for any additional AVDs you'd like to use.\n\n### Control the virtual scene\n\nWhen your app connects to ARCore, you'll see an overlay describing how to control\nthe camera and a status bar below the emulator window.\n\n#### Move the virtual camera\n\nPress and hold **Option** (macOS) or **Alt** (Linux or Windows) to access camera\nmovement controls. Use the following controls to move the camera:\n\n\u003cbr /\u003e\n\n| Platform | Action | What to do |\n|--------------------------|---------------------------|----------------------------------------|\n| **macOS** | Move left or right | Hold **Option** + press **A** or **D** |\n| | Move down or up | Hold **Option** + press **Q** or **E** |\n| | Move forward or back | Hold **Option** + press **W** or **S** |\n| | Change device orientation | Hold **Option** + move mouse |\n| **Linux** or **Windows** | Move left or right | Hold **Alt** + press **A** or **D** |\n| | Move down or up | Hold **Alt** + press **Q** or **E** |\n| | Move forward or back | Hold **Alt** + press **W** or **S** |\n| | Change device orientation | Hold **Alt** + move mouse |\n\n\u003cbr /\u003e\n\nRelease **Option** or **Alt** to return to interactive mode in the emulator.\n\nUse the **Virtual Sensors** tab in [Extended controls](//developer.android.com/studio/run/emulator.html#extended)\nfor more precise device positioning.\n\n### Troubleshooting tips\n\n- If your ARCore app launches and you see an \"AR Core not supported\" message,\n check the revision on your system image. Make sure you are using\n **API Level 27 Revision 4**.\n\n- If your ARCore app fails to open the camera when it launches, make sure that\n **Camera Back** is set to **VirtualScene** , as described in the [configuration\n steps above](#configure_the_virtual_device)."]]
