Ionic apps are created and developed primarily through the Ionic command-line utility. The Ionic CLI is the preferred method of installation, as it offers a wide range of dev tools and helps options along the way. It is also the main tool through which to run the app and connect it to other services, such as App flow.
Installing The Ionic CLI
Before proceeding, make sure your computer has Node.js installed. See these instructions to set up an environment for Ionic.
Install the Ionic CLI with npm:
npm install -g @ionic/cliIf there was a previous installation of the Ionic CLI, it will need to be uninstalled due to a change in package name.
Setup Android Studio / SDK
Android Studio is the IDE for creating native Android apps. It includes the Android SDK, which will need to be configured for use in the command line.
