Found an issue when add android platform in Ionic? how I resolve this?

That project sounds broken.

I would advice you to start a new project with ionic start and see if everything works with that one.

Would I change anything in my environmental settings?

In this where I set path 1 or 2.

Why should these be relevant in any way here?

i delete and started new project and my new project also containing same issue…

When I ran ionic cordova platform add android I found below error.,

cordova platform add android --save
Using cordova-fetch for cordova-android@~6.3.0

Error: Failed to fetch platform cordova-android@~6.3.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.
Error: cmd: Command failed with exit code ENOENT

[ERROR] Exception:

Please post the whole output of that command.
Please post your ionic info output for that project.

Your problem is probably with npm, something to do with permissions and files. This happens quite often and is almost impossible to successfully debug (at least here in the forum).

One solution: Uninstall your node, install nvm (or nvm-windows if you are on Windows), install a new node (which includes npm) with this, then install ionic and cordova again and try your command again. The problem should be gone.
