(https://facebook.github.io/react-native/releases/0.23/docs/android-setup.html)
Define the ANDROID_HOME environment variable
On Windows, go to Control Panel -> System and Security -> System -> Change settings -> Advanced -> Environment variables -> New
//
Add an environment variable ANDROID_HOME pointing at your sdk. In Windows it might look something like C:\Users\XXXX\AppData\Local\Android\Sdk . Don’t forget to restart your terminal.
