Once you see this error, wait for emulator to show lock screen. And then relaunch the app in your IDE and check the emulator again. It works for me always.
In Android studio, you can relaunch by clicking the green play button or ctrl + r.
Facing Same issues following Link helped solving the problem. The above solutions were not helpful for me. deployment-failed-could-not-access-the-package-manager-is-the-system-running
By restarting server using CMD application was back to work. Open cmd (Run as administrator), open this
cd C:\Program Files (x86)\Android\android-sdk\platform-tools
(this path must specify your android-sdk installation folder )
Now, first write,
adb kill-server
and then adb start-server
.
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.
If this error is gotten when using a rooted device's su prompt and not from emulator, disable SELinux first
setenforce 0
You may need to switch to shell user first for some pm operations
su shell
then re-run your pm
command.
Same applies to am
commands unavailable from su prompt.
Check your project build is in Debug mode not Release, I had some problem for debugging always I forget to change Release mode to Debug (Xamarin Users)
You can avoid the error by setting default device before launching application. Launch the AVD before starting the app.
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:
App should install without error.
Kill the process/server and restart it.! It worked.
The solution for me was to restart the IDE. I suspect that a slow emulator was hiding from view, blocking installation on my device.
