Ionic mobile development; Error when preparing android in Ionic

Question

I am getting an error when I add android platform and prepare android.

When I run the following command :-

 ionic capacitor add android

I get following error:-

[error] "android" platform already exists. To add a new "android" platform, please remove "D:\ionic\myapp\android" and run this command again. WARNING! your native IDE project will be completely removed. [ERROR] An error occurred while running subprocess capacitor. capacitor.cmd add android exited with exit code 1.

I updated the android by using the following command:-

ionic capacitor update android

It updated my android : -

capacitor.cmd update android √ Updating Android plugins in 73.77ms
Found 0 Capacitor plugins for android: √ update android in 473.61ms Update finished in 0.593s

Then I tried to prepare the android to start in Android studio :-

ionic cordova prepare android

I got the following error:-

cordova.cmd platform add android --save Error: npm: Command failed with exit code 1 Error output: npm ERR! code ENOLOCAL npm ERR! Could not install from "android" as it does not contain a package.json file.

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

I tried to remove cordova and install again. But it is not working.

Have I missed any plugin. I have added the capacitor in the beginning of the project.

Could anyone please suggest any solution ?
