Android - 不幸的是，相机已停止 - 默认相机

Question

我正在尝试创建一个Android虚拟机来测试一些相机应用程序。当我使用下面显示的配置选项启动AVD时，我通常会收到“不幸的是，相机已停止。”＃39;错误。有时，相机应用程序实际上工作。这是模拟器中的默认相机应用程序。

我的AVD规格：

如果图片不可用，这是AVD规范的文本：

Device: 5.4" FWVGA (480 X 854: mdpi)
Target: Android 5.0.1 - API Level 21
CPU/ABI: ARM(armeabi-v7a)
Keyboard: (checked) Hardware keyboard present 
Skin: No skin
Front Camera: None 
Back Camera: Webcam0
Memory Options: RAM:512 VM Heap:16
Internal Storage: 200 MiB
SD Card: Size 200 MiB
File: [blank]
Emulation Options: (unchecked) Snapshot (checked) Use Host GPU 

以下是相机无法启动时收到的错误图片：

如果你看不到屏幕捕获的图片错误窗口说，＆＃34;不幸的是，相机已停止＆＃34;。

当应用程序不起作用时，我会看到以下框：

当相机应用程序实际运行时，模拟器启动时网络摄像头灯也会亮起，并且不会要求我选择哪个网络摄像头。

当相机不工作时，会显示日志中这些有趣的行：

有谁知道发生了什么事？我在Windows 7操作系统上。
