Hi,
Summary of the problem
I have a mobile application project in Ionic5. I have successfully run the command npm install, but when I run ionic cordova platform add android I have this error :
sudo ionic cordova platform add android
> cordova platform add android
Using cordova-fetch for cordova-android
Failed to fetch platform cordova-android
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

What I tried
- I tried different versions of Angular, NodeJs and Ionic …
- I had completely uninstall all npm package and Node Js
- Deleted package.json
- Deleted node_module directory
- Clean npm cache
- Re-run npm install (successfuly again)
But same probleme …
I have no idea why it finds @angular/core@9.1.13 when the installed version is ~10.2.5
if anyone has an idea it will save my day 
THANKS
