android 模拟器 sdk 10 api 29 在重新安装和重启后不会启动 [英] android emulator sdk 10 api 29 won't start after remount and reboot

问题描述

我在尝试使用 SDK 10 和 API 29 重新安装设备时遇到奇怪的行为，在重新安装模拟器后挂起(设备离线)重现:

I'm running into strange behaviour when trying to remount device with SDK 10 and API 29, after the remount the emulator hang (device offline) To reproduce:

• 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 重新挂载

The adb remmount result failure as follow:
adb remount
