I expect it to add platform and do not throw any errors

Steps to reproduce:

1. Create new project: ionic start --v2 myApp
2. Install the latest version of app-scripts: npm install @ionic/app-scripts@latest
3. Run ionic platform add androoid

This is issue with cordova latest release with Android 24. So downgrade your cordova from 6.4.0 to 6.0.0 will solve this issue.

npm install -g [email protected]

It is not ionic issue.

Using the Android SDK manager you need to install the SDK Platform for Android 7.0(API 24).

Up to now you have probably been using API 23.

Hello! Thanks for opening an issue with us! As this seems like more of a support question i will urge that you ask this question on our forum. Thanks for using Ionic!

Upgrading Android SDK to platform 24 solved both issues. Please update Ionic documentation by adding it as pre-requisite for RC installation.
