但是，无论我如何尝试为不同版本的 API 创建虚拟设备，模拟器都无法正常工作。从 Visual Studio 启动时，模拟器加载窗口会永远冻结（或冻结很长时间）。当通过命令行启动时，模拟器 ( C:\Program Files (x86)\Android\android-sdk\tools\emulator.exe) 会生成：

PS C:\Program Files (x86)\Android\android-sdk\tools> ./emulator -avd nexus_one_lollipop_5_0_-_api_21 
emulator: WARNING: encryption is off
ANGLE: D3D11: rx::Renderer11::generateConfigs
emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByName: No matching signal for on_new_posture_requested(int) ((null):0, (null))


emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByName: No matching signal for on_dismiss_posture_selection_dialog() ((null):0, (null))


Failed to open /qemu.conf, err: 2
Incompatible HAX module version 3,requires minimum version 4
No accelerator found.
qemu-system-i386.exe: failed to initialize HAX: Invalid argument

之后，qemu 进程永远挂起。它仅通过任务管理器中的kill结束。

该-no-snapshot-load选项对任何事情都没有影响。我以管理员身份运行所有内容，我也尝试以简单用户身份运行它 - 结果是一样的。

如果我创建一个С:\qemu.conf文件，那么输出会改变：

emulator: WARNING: encryption is off
ANGLE: D3D11: rx::Renderer11::generateConfigs
emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByName: No matching signal for on_new_posture_requested(int) ((null):0, (null))


emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByName: No matching signal for on_dismiss_posture_selection_dialog() ((null):0, (null))


qemu-system-i386.exe:/qemu.conf:1: no group defined
emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByName: No matching signal for on_posture_valueChanged(int) ((null):0, (null))

之后，模拟器不再挂起，它只是在输出后立即退出。

我还想指出，另一个仿真器文件 ( C:\Program Files (x86)\Android\android-sdk\emulator\emulator.exe) 产生的输出略有不同。我不明白为什么会这样以及它会影响什么。

PS C:\Program Files (x86)\Android\android-sdk\emulator> ./emulator -avd nexus_one_lollipop_5_0_-_api_21
emulator: WARNING: encryption is off
C:\Program Files (x86)\Android\android-sdk\emulator\qemu\windows-x86_64\qemu-system-i386.exe:/qemu.conf:1: no group defined
PS C:\Program Files (x86)\Android\android-sdk\emulator>

现在我不知道该怎么办了。下一步是重新安装 Windows，但它太长太无聊，需要很多设置 -我现在还没准备好。

好久没用安卓开发了。似乎以前一切正常，但我不能说多久以前。也许某些组件的一些定期更新破坏了模拟器......顺便说一句，该项目正在成功组装。但是，我无法在我的 PC 上运行它。

是否可以在不重新安装 Windows 的情况下解决问题？如何？

解决方案

我的问题原来是 Visual Studio对HAXM没有任何作用。是的，是他造成了主要错误。如果您的错误输出与我的相似，则重要的问题在于 HAXM。

事实证明，从 Android SDK 菜单安装和卸载 HAXM（如问题截图所示）并不意味着实际安装或卸载。

正如我在问题中所说，以前一切都对我有用，但我很长一段时间都没有回到这个问题上。所以，我安装了HAXM，但是旧版本。由于某种原因，Visual Studio 既不能更新也不能卸载它。安装新版本时，旧版本没有被替换，被认为是优先事项，因此安装新版本而不删除旧版本并没有帮助。

如果您的旧 HAXM 安装程序（应该卸载旧 HAXM）不起作用，请继续阅读。那么，我如何修复错误：

  1. 通过 Android SDK 菜单“移除”HAXM。
  2. 检查条目（我没有Device manager在HAXM这里删除任何内容，因为我没有找到它）
  3. 删除了旧的 HAXM 文件夹C:\Windows\System32\DRVSTORE\intelhaxm_*
  4. 启动损坏的旧 HAXM 安装程序以删除 HAXM 注册表项。在人工干预之前，他不想工作，理由是缺少某种 .msi 文件。
  5. 重启电脑
  6. 我确保使用以下命令从系统中删除了旧的 HAXM：C:\Program Files (x86)\Android\android-sdk\emulator> .\emulator-check.exe accel
  7. 通过 Android SDK 菜单“安装”HAXM。（这一步没有安装任何东西——上一步的命令仍然报告没有HAXM。）
  8. 从英特尔官方存储库安装 HAXM：https://github.com/intel/haxm/releases
  9. 使用第 6 步中的命令，我确保 HAXM 安装正确（例如，显示了我 PC 上的输出）：
PS C:\Program Files (x86)\Android\android-sdk\emulator> .\emulator-check.exe accel
accel:
0
HAXM version 7.7.0 (4) is installed and usable.
accel

之后，模拟器应该可以工作了。也许Android Device Manager会显示设备模拟器已经在运行（但我没有找到qemu*和emulator处理）。可能，这可以更准确地解决，但我只是删除了现有设备并重新创建了它。
