【问题描述】：

在尝试使用 SDK 10 和 API 29 重新安装设备时，我遇到了奇怪的行为，在重新安装模拟器后挂起（设备脱机） 复制：

操作系统：MacOs
使用 android studio 定义新设备：pixel 2（或 pixel 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
List of devices attached
emulator-5554   offline

【问题讨论】：

这能回答你的问题吗？ Is adb remount broken on android api 29?

【解决方案1】：

我成功了

adb root
adb shell avbctl disable-verification
adb reboot
adb root
adb remount

【讨论】：

如果它不起作用，请使用 -writable-system 运行模拟器。
