adb remount从模拟器运行时在api 29上无法正常工作。该命令在所有其他已尝试过的模拟器（18、23、25、26、27和28）上运行良好。
知道为什么会这样吗？

我用模拟器启动模拟器-avdPixel_3a_XL_API_29可写系统-no-snapshot-load
我发现很多ppl遇到模拟器冻结和无法启动android如果你尝试
$ adb root
$ adb disable-verity
$ adb reboot <--- By now emulator is freezed
那你可以试试这个
$ adb root
$ adb shell avbctl disable-verification <--- this will not freeze the emulator
$ adb reboot
当模拟器重新启动时尝试重新挂载将没有问题
adb root
adb remount
adb push将能够在system目录上编写
参见@KiddDon答案，这似乎是一个实际的解决方案

即使API30（APIR），此问题仍然存在！甚至在使用可写系统选项启动模拟器时：（模拟器-可写系统-avdNAME_OF_DEVICE）！
我尝试按照这些说明禁用-verity并在重新挂载之前重新启动
注意：我在使用带有“AVD”提供的“Android Sdk图像”的模拟器时遇到了当前问题。但是，这种图像可能会受到一些限制。所以其他类型的Android图像可能不会发生这种情况
$ adb root
$ adb disable-verity
$ adb reboot
$ adb wait-for-device
$ adb root
$ adb remount
$ adb shell stop
$ adb sync
$ adb shell start
$ adb reboot
$ adb push <source> <destination>
$ adb reboot
$ adb disable-verity
$ adb reboot
$ adb remount -R
注意：如果设备已经处于adb remount状态，则-R不会重新启动。
