I have finished a project, and I would like to build an apk. I have tried to build it, but after writing the sentences to build it, the third code gave me an error. Here the code or sentences I wrote to be built it.

ionic cordova platform remove android
ionic cordova plarform add android@6.4.0
ionic cordova build android

I have built a project 3 day ago following the code I wrode above. Here the error. ( this time I connect with firebase)

Platform android already added.
[ERROR] An error occurred while running subprocess cordova.

        cordova platform add android@6.4.0 --save exited with exit code 1.

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

E:\ionic\notasFirebase>ionic cordova build android

ERROR An error occurred while running subprocess cordova this can occur due to many reasons Plz check weather all plugins in package.json file are loading correct If any of that is deprecated or any extra plugin is present which is not useful but its in package.json remove that and build the apk this may solve the problem

I encountered this error, and I reinstalled Cordova:

npm uninstall -g cordova
npm install -g cordova

And it works on my side. There are other reasons for this error, so I am not sure this will work on your side.
