android 模拟器 sdk 10 api 29 在重新安装和重启后不会启动

Question

在重新安装模拟器挂起（设备离线）后，尝试使用 SDK 10 和 API 29 重新安装设备时，我遇到了奇怪的行为要重现：

• 操作系统：MacOS
• 使用 android studio 定义新设备：像素 2（或像素 3/nexus 5）、Android 10.0 x86、API 29
• 使用命令行启动模拟器： emulator -avd Pixel_2_API_29_SDK10 -writable-system -verbose
• 运行adb -s emulator-5554 root
• 运行adb -s emulator-5554 remount

The adb remmount result failure as follow:
adb remount

• 运行： adb -s emulator-5554 reboot adb reboot导致模拟器挂起

➜  ~ adb devices
