问题


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:

  • OS: MacOs
  • Using android studio define new device: pixel 2 (or pixel 3/nexus 5), Android 10.0 x86, API 29
  • start the emulator using command line: emulator -avd Pixel_2_API_29_SDK10 -writable-system -verbose
  • run adb -s emulator-5554 root
  • run adb -s emulator-5554 remount
The adb remmount result failure as follow:
adb remount
