Resolved! “The platform ‘35729’ does not appear to have been added to this project.”

I was working on an Ionic 3 project and debugging application live with connected Android devices by running following command

$ ionic cordova run android --device

 

Then suddenly it stopped working and showing following error in cmd

> cordova run android --proxy --device --livereload-port 35729 --dev-logger-port
 53703
Android Studio project detected
The platform "35729" does not appear to have been added to this project.
[ERROR] An error occurred while running subprocess cordova.

        cordova run android --proxy --device --livereload-port 35729
        --dev-logger-port 5... exited with exit code 1.

        Re-running this command with the --verbose flag may provide more
        information.

I also tried to reconnect device then disable/ enable device developer option, but nothing worked.

Then came to know that could be related to Ionic CLI update from 4.9.0 to 4.10.0 which I just upgraded a few minutes back

After that, I just downgraded my Ionic CLI version by running following cmd command

$ npm i [email protected]

That's it everything worked fine after that
