could not access the package manager. is the system running while installing android application
You need to wait for the emulator to full start - takes a few minutes. Once it is fully started (UI on the emulator will change), it should work.
You will need to restart the app after the emulator is running and choose the running emulator when prompted.
As other have said, this error occurs because the emulator is still in the process of launching. An attempt to access the package manager, for the device, at this time causes an error.
It's just a simple timing issue. Here are the steps to avoid this error:
- Wait until the emulator 'lock screen' is showing.
- Run the 'app' again (^R in most IDE's).
- Choose the running device (Should be the same emulator).
App should install without error.
In my case it was just that the emulator took 9 minutes to start. Wait until you see the lock icon on the emulator LCD. Or use actual tablet or phone.
