Android模拟器重启失败

Question

我使用Visual Studio 2019安装了Android模拟器，并使用Windows功能启用了hyper-v和hypervisor平台。

我使用“ Android设备管理器”工具创建了新设备，当我启动它时，它运行良好。但是，如果我关闭它并重新开始，它将打开，并且屏幕显示上次会话的最后状态。然后什么也没有发生，它永远不会加载。如果我将设备系统设置恢复为默认状态并重新启动，则可以正常运行，但是我不想每次都这样做，而且我希望能够在会话之间存储应用程序数据。

那我该如何工作呢？

还是我如何使其停止尝试保存状态，始终开始冷态？

我有Windows 10，Android仿真器版本28.0.25，SDK工具26.1.1，SDK平台工具28.0.2。

我的设备的config.ini：

Answer 1

有一个名为Quickboot的设置，您可以为每个AVD分别禁用它，它将每次都进行冷启动。

但这不是最好的解决方案，我希望Quickboot能够实际工作。
