Root android emulator mac android studio how to#
I've tried emulator -avd -writeable-system but I get 'emulator' is not recognized as an internal or external command, operable program or batch file.Ĭan someone please help me figure out how to run the emulator in such a way that I can write to /system? It appears to work, but if I then try to write to /system, I get mv: /system: Read-only file system) I've tried adb shell mount -o rw,remount /system, but I get mount: '/system' not in /proc/mounts.īut get the same mount: '/system' not in /proc/mounts error (I also tried running adb disable-verity and rebooting before remounting, but I still get the same remount error.)

I've made sure to run adb root and that works, though adb remount gives remount of the / superblock failed: Permission denied as an error. I'm currently using the Pixel 2 - API 28 AVD (targets Android 9.0). I've made sure to use a rootable, non-Google Play Services AVD. I want to be able to write to /system in my Android Studio Emulator.
